PROSPECTUS SUPPLEMENT

(To Base Shelf Prospectus dated June 12, 2020)

US$80,000,000

Common Shares

Oncolytics Biotech Inc. (“Oncolytics” or the “Corporation”) has entered into an equity distribution agreement dated March 4, 2021 (the “Equity Distribution Agreement”) with Canaccord Genuity LLC (the “Agent”) relating to our common shares (“Common Shares”) pursuant to which we may offer and sell Common Shares having an aggregate offering price of up to US$80,000,000. This Prospectus Supplement qualifies for distribution an aggregate of up to US$80,000,000 of our Common Shares that may be offered and sold through the Agent, as our agent, under the Equity Distribution Agreement (the “Offering”). See “Plan of Distribution” beginning on page S-19 of this Prospectus Supplement for more information regarding these arrangements.

Our Common Shares are listed on the Nasdaq Capital Market (“NASDAQ”) under the symbol “ONCY” and on the Toronto Stock Exchange (“TSX”) under the symbol “ONC”. On March 4, 2021, the last reported sale price of our Common Shares was US$3.05 per Common Share on NASDAQ and C$3.91 per Common Share on the TSX.

Upon delivery of a placement notice by us, if any, the Agent may sell the Common Shares in the United States only and such sales will only be made by transactions that may be considered to be “at-the-market distributions” as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”), including, without limitation, sales made directly on NASDAQ, or on any other existing trading market for the Common Shares in the United States. No Common Shares will be sold on the TSX or on other trading markets in Canada as at-the-market distributions. The Agent will make all sales using commercially reasonable efforts consistent with their normal sales and trading practices and on mutually agreed upon terms between the Agent and us. The Common Shares will be distributed at the market prices prevailing at the time of the sale of such Common Shares. As a result, prices may vary as between purchasers and during the period of distribution. There is no arrangement for funds to be received in escrow, trust or similar arrangement.

The compensation to the Agent for sales of our Common Shares under this Prospectus Supplement will not exceed three percent (3%) of the gross proceeds from the sale of such Common Shares. See “Plan of Distribution” in this Prospectus Supplement.

The net proceeds, if any, from sales under this Prospectus Supplement will be used as described under the section titled “Use of Proceeds” in this Prospectus Supplement. The proceeds we receive from sales will depend on the number of Common Shares actually sold and the offering price of such Common Shares. We estimate the total expenses of this Offering, excluding the Agent’s fee, will be approximately US$200,000.

In connection with the sale of the Common Shares on our behalf, the Agent will be deemed to be an “underwriter” within the meaning of Section 2(a)(11) of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and the compensation of the Agent will be deemed to be an underwriting commission or discount. We have agreed to provide indemnification and contribution to the Agent against certain liabilities, including liabilities under the U.S. Securities Act.

Neither the Agent, nor any of its affiliates or any person or company acting jointly or in concert with the Agent, has over-alloted, or will over-allot, Common Shares in connection with the Offering or effect any other transactions that are intended to stabilize or maintain the market price of the Common Shares.

An investment in the Common Shares is speculative and bears certain risks. See “Risk Factors” on beginning on page S-10 in this Prospectus Supplement and on page 6 of the accompanying Prospectus.

This Offering is made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States and Canada (“MJDS”), to prepare this Prospectus Supplement and the Prospectus in accordance with Canadian disclosure requirements. Prospective investors in the United States should be aware that such requirements are different from those of the United States. Financial statements included or incorporated by reference in the Prospectus have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and may not be comparable to financial statements of United States companies. Such financial statements are subject to auditor independence standards, in addition to the standards of the Public Company Accounting Oversight Board (United States) and the United States Securities and Exchange Commission (“SEC”) independence standards.

Prospective investors should be aware that the acquisition of the Common Shares described herein may have tax consequences both in the United States and in Canada. Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein. This Prospectus Supplement and the Prospectus may not describe these tax consequences fully. You should read the tax discussion under the headings “Certain Canadian Federal Income Tax Considerations” and “Material United States Federal Income Tax Considerations” in this Prospectus Supplement.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Corporation is incorporated under the laws of Alberta, Canada, that the majority of its officers and directors are residents of Canada, that many of the experts named in this Prospectus Supplement and the Prospectus are not residents of the United States, and that a substantial portion of the assets of the Corporation and said persons are located outside the United States.

NEITHER THE SEC NOR ANY STATE OR CANADIAN SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED THE SECURITIES OFFERED HEREBY OR DETERMINED IF THIS PROSPECTUS SUPPLEMENT OR THE ACCOMPANYING PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE. Messrs. Wayne Pisano and Leonard Kruimer and Drs. William G. Rice and Bernd R. Seizinger are directors of the Corporation who reside outside of Canada. Messrs. Pisano and Kruimer and Drs. Rice and Seizinger have appointed the Corporation, at its principal place of business, as agent for service of process. Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that resides outside of Canada, even if the party has appointed an agent for service of process.

RISK FACTORS

Prospective purchasers of Common Shares should consider carefully the risk factors set out in this Prospectus Supplement, the Prospectus and the documents incorporated by reference in the Prospectus. Discussions of certain risks affecting Oncolytics in connection with its business are set forth under “Risk Factors” in the Prospectus and in our annual disclosure documents filed with the various securities regulatory authorities which are incorporated by reference in the Prospectus.

Volatility of market price of the Common Shares

The market price of the Common Shares may be volatile. The volatility may affect the ability of holders of Common Shares to sell the Common Shares at an advantageous price. Market price fluctuations in the Common Shares may be due to the Corporation’s operating results failing to meet the expectations of securities analysts or investors in any quarter, downward revision in securities analysts’ estimates, governmental regulatory action, adverse change in general market conditions or economic trends, acquisitions, dispositions or other material public announcements by the Corporation or its competitors, along with a variety of additional factors, including, without limitation, those set forth under “Forward-Looking Statements” in this Prospectus Supplement. In addition, the market price for securities in the stock markets, including the NASDAQ and the TSX, recently experienced significant price and trading fluctuations. These fluctuations have resulted in volatility in the market prices of securities that often has been unrelated or disproportionate to changes in operating performance. These broad market fluctuations may adversely affect the market price of the Common Shares.

The Corporation will have broad discretion over the use of the net proceeds from the Offering and the Corporation may not use these proceeds in a manner desired by the Corporation’s shareholders

Management will have broad discretion with respect to the use of the net proceeds from the Offering and investors will be relying on the judgment of management regarding the application of these proceeds. Management could spend most of the net proceeds from the Offering in ways that the Corporation’s shareholders may not desire or that do not yield a favorable return. You will not have the opportunity, as part of your investment in the Common Shares, to influence the manner in which the net proceeds of the Offering are used. At the date of this Prospectus Supplement, the Corporation intend to use the net proceeds from the Offering as described under the heading “Use of Proceeds”. However, the Corporation’s needs may change as the business and the industry the Corporation addresses evolve. As a result, the proceeds to be received in the Offering may be used in a manner significantly different from the Corporation’s current expectations.

The Common Shares offered hereby will be sold in “at-the-market” offerings, and investors who buy Common Shares at different times will likely pay different prices

Investors who purchase Common Shares in this Offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. The Corporation will have discretion, subject to market demand, to vary the timing, prices, and numbers of Common Shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their Common Shares as a result of share sales made at prices lower than the prices they paid.

The Corporation does not currently intend to pay any cash dividends on the Common Shares; therefore, the Corporation’s shareholders may not be able to receive a return on their Common Shares until they sell them

The Corporation has not declared or paid any dividends since its incorporation. The Corporation currently intends to retain earnings, if any, to finance the growth and development of its business and does not currently intend to pay cash dividends on the Common Shares in the foreseeable future. Any return on an investment in the Common Shares will likely come from the appreciation, if any, in the value of the Common Shares. The payment of future cash dividends, if any, will be reviewed periodically by our board of directors and will depend upon, among other things, conditions then existing including earnings, financial condition and capital requirements, restrictions in financing agreements, business opportunities and conditions and other factors.

You may be unable to enforce actions against us, certain of our directors and officers, or the experts named in this Prospectus Supplement under U.S. federal securities laws.

We are a company continued under the laws of the Province of Alberta, Canada. Most of our directors and officers as well as the certain of the experts named in this Prospectus Supplement and the accompanying Prospectus, reside principally in Canada. Because all or a substantial portion of our assets and the assets of these persons are located outside of the United States, it may not be possible for you to effect service of process within the United States upon us or those persons. Furthermore, it may not be possible for you to enforce against us or those persons in the United States, judgments obtained in U.S. courts based upon the civil liability provisions of the U.S. federal securities laws or other laws of the United States. There is doubt as to the enforceability, in original actions in Canadian courts, of liabilities based upon U.S. federal securities laws and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based upon the civil liability provisions of the U.S. federal securities laws. Therefore, it may not be possible to enforce those actions against us, certain of our directors and officers or certain of the experts named in this Prospectus Supplement.

The Corporation is likely a “passive foreign investment company” which may have adverse U.S. federal income tax consequences for U.S. shareholders

U.S. holders of Common Shares should be aware that the Corporation believes it was classified as a passive foreign investment company (“PFIC”) during the tax year ended December 31, 2020, and based on current business plans and financial expectations, the Corporation expects that it will be a PFIC for the current tax year and may be a PFIC in future tax years. If the Corporation is a PFIC for any year during a U.S. shareholder’s holding period of the Common Shares, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any “excess distribution” received on its Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distribution, unless the shareholder makes a timely and effective “qualified electing fund” election (“QEF Election”) or a “mark-to-market” election with respect to the Common Shares. A U.S. shareholder who makes a QEF Election generally must report on a current basis its share of the Corporation’s net capital gain and ordinary earnings for any year in which the Corporation is a PFIC, whether or not the Corporation distributes any amounts to its shareholders. A U.S. shareholder who makes a mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer’s adjusted tax basis therein. This paragraph is qualified in its entirety by the discussion below under the heading “Material United States Federal Income Tax Considerations.” Each U.S. shareholder should consult its own tax advisors regarding the PFIC rules and the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.

THE CORPORATION

Oncolytics Biotech Inc. was incorporated pursuant to the ABCA on April 2, 1998 as 779738 Alberta Ltd. On April 8, 1998, we amended our articles of incorporation (the “Articles”) and changed our name to Oncolytics Biotech Inc. On July 29, 1999, we amended our Articles by removing the private company restrictions included therein and subdivided the 2,222,222 Common Shares issued and outstanding into 6,750,000 Common Shares. On February 9, 2007, we amended our Articles to permit shareholder meetings to be held at any place in Alberta or at any other location as determined by our board of directors. On May 22, 2019, we amended our Articles of Incorporation to effect a consolidation of the Common Shares on the basis of 9.5 pre-consolidation Common Shares for each one post-consolidation Common Share.

We have two material operating subsidiaries: Oncolytics Biotech (Barbados) Inc. and Oncolytics Biotech (US) Inc., a Delaware corporation. Oncolytics Biotech (Barbados) Inc. is incorporated pursuant to the laws of Barbados and is a wholly-owned direct subsidiary of the Corporation. Oncolytics Biotech (U.S.) Inc. is incorporated pursuant to the laws of Delaware and is a wholly-owned direct subsidiary of Oncolytics Biotech (Barbados) Inc.

Our head office and principal place of business is located at 210, 1167 Kensington Crescent N.W., Calgary, Alberta, T2N 1X7. Our registered office is located at 4000, 421 - 7^th Avenue S.W., Calgary, Alberta, T2P 4K9.

BUSINESS OF THE CORPORATION

Since our inception in April of 1998, Oncolytics Biotech Inc. has been a development stage company and we have focused our research and development efforts related to pelareorep, a systemically administered immuno-oncology viral agent with the potential to treat a variety of cancers. We have not been profitable since our inception and expect to continue to incur substantial losses as we continue research and development efforts. We do not expect to generate significant revenues until, if and when, pelareorep becomes commercially viable.

Our potential product for human use, pelareorep, an unmodified reovirus, is a first in class systemically administered immuno-oncology viral agent for the treatment of solid tumors and hematological malignancies.

For further information regarding our business, see our Annual Report and other documents incorporated by reference in this Prospectus Supplement which are available electronically under the Corporation’s profile on SEDAR (www.sedar.com) and on EDGAR (www.sec.gov/edgar.shtml).

USE OF PROCEEDS

The net proceeds from the Offering are not determinable in light of the nature of the distribution. The net proceeds of any given distribution of Common Shares through the Agent in an “at-the-market distribution” will represent the gross proceeds after deducting the compensation payable to the Agent under the Equity Distribution Agreement and expenses of the distribution. The Agent will receive a cash fee not exceeding three percent (3%) of the gross proceeds realized from the sale of our Common Shares for services rendered in connection with the Offering. We estimate the total expenses of the Offering, excluding the fee paid to the Agent, will be approximately US$250,000.

We intend to use the net proceeds from the Offering, if any, for the advancement of the Corporation’s clinical development program, related support costs and general corporate and administrative expenses. General corporate and administrative expenses may include funding ongoing operations and/or capital requirements, discretionary capital programs and potential future acquisitions. Although, the Corporation intends to expend the net proceeds from the Offering as set forth above, there may be circumstances where for sound business reasons, a reallocation of funds may be deemed prudent or necessary, and may vary materially from that set forth above. Pending the uses described above, we plan to invest the net proceeds from the Offering in short- and intermediate-term, interest bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

The amounts actually expended for the purposes described above may vary significantly depending upon a number of factors, including those listed under the heading “Risk Factors” in this Prospectus Supplement.

CONSOLIDATED CAPITALIZATION

Except for the issuance of Common Shares of the Corporation as set forth under the heading “Prior Sales” in this Prospectus Supplement, there has not been any material change in the share and loan capital of the Corporation, on a consolidated basis, since the Corporation’s most recently filed financial statements for the year ended December 31, 2020.

TRADING PRICE AND VOLUME

The Common Shares are listed and posted for trading on the TSX under the trading symbol “ONC” and on the NASDAQ under the trading symbol “ONCY”. On March 4, 2021, the closing bid price of our Common Shares on the NASDAQ was US$3.05 and the closing price of our Common Shares on the TSX was C$3.91.

The following table sets forth the market price ranges and the aggregate volume of trading of the Common Shares on the TSX and NASDAQ for the periods indicated:

PRIOR SALES

Except as disclosed under this heading, no other Common Shares or securities exchangeable or convertible into Common Shares have been issued during the twelve month period preceding the date of this Prospectus Supplement.

Common Shares

During the twelve month period prior to the date of this Prospectus Supplement, the Corporation has issued:

Stock Options

During the twelve month period preceding the date of this Prospectus Supplement, the Corporation granted stock options pursuant to its amended and restated stock option plan exercisable for an aggregate of 1,757,500 Common Shares. The particulars of such grants are set forth in the following table:

Share Awards

During the twelve month period preceding the date of this Prospectus Supplement, the Corporation granted restricted share awards pursuant to its amended and restated incentive share award plan which, upon vesting, will entitle the holders thereof to receive up to an aggregate of 148,493 Common Shares. The particulars of such grants are set forth in the following table:

PLAN OF DISTRIBUTION

We have entered into the Equity Distribution Agreement with the Agent under which we may issue and sell from time to time up to US$80,000,000 of our Common Shares through the Agent, as agent. Common Shares having an aggregate Offering amount of up to US$80,000,000 are being offered under this Prospectus Supplement.

Sales of the Common Shares will be made in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102, including sales made directly on the NASDAQ or other existing trading markets in the United States. Subject to the terms and conditions of the Equity Distribution Agreement and upon delivery of a placement notice from us, the Agent will solicit offers to purchase our Common Shares directly on the NASDAQ or other existing trading markets in the United States. We will instruct the Agent as to the number of Common Shares to be sold by them from time to time. No Common Shares will be sold on the TSX or on other trading markets in Canada as at-the-market distributions. We may instruct the Agent not to the sell Common Shares if the sales cannot be effected at or above the price designated by us from time to time. We or the Agent may suspend the Offering of the Common Shares upon notice and subject to other conditions.

We will pay the Agent commissions, in cash, for its services in acting as agent in the sale of our Common Shares. The Agent will be entitled to compensation at a fixed commission rate of 3.0% of the gross sales price per Common Share sold. Because there is no minimum offering amount required as a condition to close the Offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We have also agreed to reimburse the Agent for certain specified expenses, including the fees and disbursements of its legal counsel, in an amount not to exceed US$50,000. We estimate that the total expenses for the Offering, excluding compensation and reimbursements payable to the Agent under the terms of the Equity Distribution Agreement, will be approximately US$200,000.

Settlement for sales of our Common Shares will occur on the second business day following the date on which any sales are made, or on such other date as is industry practice for regular-way trading, in return for payment of the net proceeds to us. Sales of our Common Shares as contemplated in this Prospectus will be settled through the facilities of The Depository Trust Company or by such other means as we and the Agent may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

The Agent will use its commercially reasonable efforts, consistent with its sales and trading practices, to solicit offers to purchase the Common Shares under the terms and subject to the conditions set forth in the Equity Distribution Agreement. In connection with the sale of the Common Shares on our behalf, the Agent will be deemed to be an “underwriter” within the meaning of the U.S. Securities Act, and the compensation of the Agent will be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the Agent against certain civil liabilities, including liabilities under the U.S. Securities Act.

The offering of Common Shares pursuant to the Equity Distribution Agreement will terminate upon the earlier of (i) the sale of all Common Shares subject to the Equity Distribution Agreement, or (ii) termination of the Equity Distribution Agreement as permitted therein. We and the Agent may each terminate the Equity Distribution Agreement at any time upon ten days’ prior notice.

The Agent and its affiliates may in the future provide various investment banking, commercial banking and other financial services for us and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, the Agent will not engage in any market making activities involving our Common Shares while the Offering is ongoing under this Prospectus Supplement.

No underwriter of the Offering, and no person or company acting jointly or in concert with an underwriter, may, in connection with the distribution under this Prospectus Supplement, enter into any transaction that is intended to stabilize or maintain the market price of the Common Shares distributed under this Prospectus Supplement, including selling an aggregate number of Common Shares that would result in the underwriter creating an over-allocation position in the Common Shares.

The TSX has conditionally approved the listing of the Common Shares offered by this Prospectus Supplement. Listing is subject to us fulfilling all of the requirements of the TSX. The Company has provided notice to NASDAQ for the listing of the Common Shares offered hereunder.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date of this Prospectus Supplement, a summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (“Tax Act”) and the regulations thereunder (the “Regulations”) generally applicable to an investor who acquires as beneficial owner Common Shares pursuant to the Offering and who, for the purposes of the Tax Act and the Regulations and at all relevant times deals at arm’s length with the Corporation and the Agent, is not affiliated with the Corporation or the Agent, is not exempt from tax under Part I of the Tax Act, and who acquires and holds the Common Shares, as capital property (a “Holder”). Generally, the Common Shares will be considered to be capital property to a Holder provided that the Holder does not hold the Common Shares in the course of carrying on a business as part of an adventure or concern in the nature of trade.

This summary is generally applicable to a Holder who, at all relevant times, for purposes of the Tax Act: (i) is not, and is not deemed to be, resident in Canada for the purposes of the Tax Act or any applicable income tax treaty or convention; and (ii) does not and will not use or hold, and is not and will not be deemed to hold, the Common Shares in connection with carrying on a business in Canada (a “Non-Resident Holder”).

Special rules, which are not discussed in this summary, may apply to certain holders that are insurers carrying on an insurance business in Canada and elsewhere. Such Holders should consult their own tax advisors with respect to an investment in Common Shares.

This summary is based upon the current provisions of the Tax Act and the Regulations in force as of the date hereof and counsel’s understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing by the CRA prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act and the Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”) and assumes that the Tax Proposals will be enacted in the form proposed, although no assurance can be given that the Tax Proposals will be enacted in their current form or at all.

Other than the Tax Proposals, this summary does not otherwise take into account or anticipate any changes in law, whether by legislative, governmental, administrative or judicial decision or action, nor does it take into account or consider any provincial, territorial or foreign income tax considerations, which considerations may differ significantly from the Canadian federal income tax considerations discussed in this summary. This summary also does not take into account any change in the administrative policies or assessing practices of the CRA.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. Holders should consult their own tax advisors with respect to their particular circumstances.

Currency

For purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of the Common Shares (including dividends, adjusted cost base and proceeds of disposition) must, to the extent such amounts are not in Canadian dollars, be converted into Canadian dollars based on an exchange rate determined in accordance with the Tax Act.

Dividends

Dividends paid or credited or deemed to be paid or credited on the Common Shares to a Non-Resident Holder by the Corporation are subject to Canadian withholding tax at the rate of 25% on the gross amount of the dividend, unless such rate is reduced by the terms of an applicable tax treaty. For example, under the Canada-United States Tax Convention (1980), as amended (the “Treaty”), the rate of withholding tax on dividends paid or credited to a Non-Resident Holder who is a beneficial owner of dividends and who is a resident of the United States for purposes of the Treaty and who is entitled to the benefits of the Treaty is generally limited to 15% of the gross amount of the dividend. Non-Resident Holders are urged to consult their own tax advisors to determine their entitlement to relief under an applicable income tax treaty.

Dispositions of Common Shares

Upon a disposition (or a deemed disposition) of a Common Share (other than to the Corporation unless purchased by the Corporation in the open market in the manner in which shares are normally purchased by any member of the public in the open market), a Non-Resident Holder generally will realize a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition of such Common Shares, net of any reasonable costs of disposition, are greater (or are less) than the adjusted cost base of such Common Share to the Non-Resident Holder.

A Non-Resident Holder generally will not be subject to tax under the Tax Act in respect of a capital gain realized on the disposition or deemed disposition of a Common Share, unless the Common Share constitutes “taxable Canadian property” and is not “treaty-protected property” (each as defined under the Tax Act) of the Non-Resident Holder at the time of disposition.

Provided the Common Shares are listed on a “designated stock exchange”, as defined in the Tax Act (which currently includes the NASDAQ and TSX), at the time of disposition, the Common Shares generally will not constitute taxable Canadian property of a Non-Resident Holder at that time, unless at any time during the 60 month period immediately preceding the disposition the following two conditions are met concurrently: (i) one or any combination of (a) the Non-Resident Holder, (b) persons with whom the Non-Resident Holder did not deal at arm’s length, and (c) partnerships in which the Non-Resident Holder or a person with whom the Non-Resident Holder did not deal at arm’s length held a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any class or series of shares of the Corporation; and (ii) more than 50% of the fair market value of such shares was derived directly or indirectly from one or any combination of (a) real or immovable property situated in Canada, (b) “Canadian resource properties” (as defined in the Tax Act), (c) “timber resource properties” (as defined in the Tax Act) or (d) an option in respect of, an interest in, or for civil law a right in any of the foregoing property, whether or not such property exists. Notwithstanding the foregoing, a Common Share may otherwise be deemed to be taxable Canadian property to a Non-Resident Holder for purposes of the Tax Act.

Non-Resident Holders whose Common Shares may be taxable Canadian property should consult their own tax advisors.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined below) arising from and relating to the acquisition, ownership, and disposition of Common Shares acquired pursuant to this Offering.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder arising from and relating to the acquisition, ownership, and disposition of Common Shares. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including, without limitation, specific tax consequences to a U.S. Holder under an applicable income tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. Holder. This summary does not address the U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences to U.S. Holders of the acquisition, ownership, and disposition of Common Shares. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each prospective U.S. Holder should consult its own tax advisors regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Common Shares.

No legal opinion from U.S. legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

Scope of this Summary

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations (whether final, temporary, or proposed), published rulings of the IRS, published administrative positions of the IRS, the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, signed September 26, 1980, as amended (the “Canada-U.S. Tax Convention”), and U.S. court decisions that are applicable, and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be changed in a material and adverse manner at any time, and any such change could be applied retroactively. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation.

U.S. Holders

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of Common Shares acquired pursuant to this Offering that is for U.S. federal income tax purposes:

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (d) have a “functional currency” other than the U.S. dollar; (e) own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) acquire Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) are required to accelerate the recognition of any item of gross income with respect to Common Shares as a result of such income being recognized on an applicable financial statement; or (i) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of the outstanding shares of the Corporation. This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Tax Act; (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Common Shares in connection with carrying on a business in Canada; (d) persons whose Common Shares constitute “taxable Canadian property” under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Canada-U.S. Tax Convention. U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders described immediately above, should consult their own tax advisors regarding the U.S. federal, U.S. federal alternative minimum, U.S. federal net investment income, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of Common Shares.

If an entity or arrangement that is classified as a partnership (or other “pass-through” entity) for U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax consequences to such entity or arrangement and the partners (or other owners or participants) of such entity or arrangement generally will depend on the activities of the entity or arrangement and the status of such partners (or owners or participants). This summary does not address the tax consequences to any such partner (or owner or participants). Partners (or other owners or participants) of entities or arrangements that are classified as partnerships or as “pass-through” entities for U.S. federal income tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Common Shares.

Passive Foreign Investment Company Rules

PFIC Status of the Corporation

If the Corporation were to constitute a “passive foreign investment company” under the meaning of Section 1297 of the Code (a “PFIC”, as defined below) for any year during a U.S. Holder’s holding period, then certain potentially adverse rules would affect the U.S. federal income tax consequences to a U.S. Holder as a result of the acquisition, ownership and disposition of Common Shares. The Corporation believes that it was classified as a PFIC during the tax year ended December 31, 2020, and based on current business plans and financial expectations, the Corporation expects that it will be a PFIC for the current tax year and may be a PFIC in future tax years. No opinion of legal counsel or ruling from the IRS concerning the status of the Corporation as a PFIC has been obtained or is currently planned to be requested. The determination of whether any corporation was, or will be, a PFIC for a tax year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition, whether any corporation will be a PFIC for any tax year depends on the assets and income of such corporation over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this document. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Corporation (or any subsidiary of the Corporation) concerning its PFIC status. Each U.S. Holder should consult its own tax advisors regarding the PFIC status of the Corporation and each subsidiary of the Corporation.

In any year in which the Corporation is classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. In addition to penalties, a failure to satisfy such reporting requirements may result in an extension of the time period during which the IRS can assess a tax. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621 annually.

The Corporation generally will be a PFIC if, for a tax year, (a) 75% or more of the gross income of the Corporation is passive income (the “PFIC income test”) or (b) 50% or more of the value of the Corporation’s assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the “PFIC asset test”). “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

For purposes of the PFIC income test and PFIC asset test described above, if the Corporation owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the Corporation will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and PFIC asset test described above, and assuming certain other requirements are met, “passive income” does not include certain interest, dividends, rents, or royalties that are received or accrued by the Corporation from certain “related persons” (as defined in Section 954(d)(3) of the Code) also organized in Canada, to the extent such items are properly allocable to the income of such related person that is not passive income.

Under certain attribution rules, if the Corporation is a PFIC, U.S. Holders will generally be deemed to own their proportionate share of the Corporation’s direct or indirect equity interest in any company that is also a PFIC (a ‘‘Subsidiary PFIC’’), and will generally be subject to U.S. federal income tax on their proportionate share of (a) any “excess distributions,” as described below, on the stock of a Subsidiary PFIC and (b) a disposition or deemed disposition of the stock of a Subsidiary PFIC by the Corporation or another Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC. In addition, U.S. Holders may be subject to U.S. federal income tax on any indirect gain realized on the stock of a Subsidiary PFIC on the sale or disposition of Common Shares. Accordingly, U.S. Holders should be aware that they could be subject to tax under the PFIC rules even if no distributions are received and no redemptions or other dispositions of Common Shares are made.

Default PFIC Rules Under Section 1291 of the Code

If the Corporation is a PFIC for any tax year during which a U.S. Holder owns Common Shares, the U.S. federal income tax consequences to such U.S. Holder of the acquisition, ownership, and disposition of Common Shares will depend on whether and when such U.S. Holder makes an election to treat the Corporation and each Subsidiary PFIC, if any, as a “qualified electing fund” or “QEF” under Section 1295 of the Code (a “QEF Election”) or makes a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”). A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a “Non-Electing U.S. Holder.”

A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of the Code (described below) with respect to (a) any gain recognized on the sale or other taxable disposition of Common Shares and (b) any “excess distribution” received on the Common Shares. A distribution generally will be an “excess distribution” to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a U.S. Holder’s holding period for the Common Shares, if shorter).

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of Common Shares (including an indirect disposition of the stock of any Subsidiary PFIC), and any “excess distribution” received on Common Shares or with respect to the stock of a Subsidiary PFIC, must be ratably allocated to each day in a Non-Electing U.S. Holder’s holding period for the respective Common Shares. The amount of any such gain or excess distribution allocated to the tax year of disposition or distribution of the excess distribution and to years before the entity became a PFIC, if any, would be taxed as ordinary income (and not eligible for certain preferred rates). The amounts allocated to any other tax year would be subject to U.S. federal income tax at the highest tax rate applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as “personal interest,” which is not deductible.

If the Corporation is a PFIC for any tax year during which a Non-Electing U.S. Holder holds Common Shares, the Corporation will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether the Corporation ceases to be a PFIC in one or more subsequent tax years. A Non-Electing U.S. Holder may terminate this deemed PFIC status by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above), but not loss, as if such Common Shares were sold on the last day of the last tax year for which the Corporation was a PFIC.

QEF Election

A U.S. Holder that makes a timely and effective QEF Election for the first tax year in which the holding period of its Common Shares begins generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Common Shares. A U.S. Holder that makes a timely and effective QEF Election will be subject to U.S. federal income tax on such U.S. Holder’s pro rata share of (a) the net capital gain of the Corporation, which will be taxed as long-term capital gain to such U.S. Holder, and (b) the ordinary earnings of the Corporation, which will be taxed as ordinary income to such U.S. Holder. Generally, “net capital gain” is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and “ordinary earnings” are the excess of (a) “earnings and profits” over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each tax year in which the Corporation is a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by the Corporation. However, for any tax year in which the Corporation is a PFIC and has no net income or gain, U.S. Holders that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a U.S. Holder that made a QEF Election has an income inclusion, such a U.S. Holder may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as “personal interest,” which is not deductible.

A U.S. Holder that makes a timely and effective QEF Election with respect to the Corporation generally (a) may receive a tax-free distribution from the Corporation to the extent that such distribution represents “earnings and profits” of the Corporation that were previously included in income by the U.S. Holder because of such QEF Election and (b) will adjust such U.S. Holder’s tax basis in the Common Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a U.S. Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Common Shares.

The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as “timely” if such QEF Election is made for the first year in the U.S. Holder’s holding period for the Common Shares in which the Corporation was a PFIC. A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such year. If a U.S. Holder does not make a timely and effective QEF Election for the first year in the U.S. Holder’s holding period for the Common Shares, the U.S. Holder may still be able to make a timely and effective QEF Election in a subsequent year if such U.S. Holder meets certain requirements and makes a “purging” election to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Common Shares were sold for their fair market value on the day the QEF Election is effective. If a U.S. Holder makes a QEF Election but does not make a “purging” election to recognize gain as discussed in the preceding sentence, then such U.S. Holder shall be subject to the QEF Election rules and shall continue to be subject to tax under the rules of Section 1291 discussed above with respect to its Common Shares. If a U.S. Holder owns PFIC stock indirectly through another PFIC, separate QEF Elections must be made for the PFIC in which the U.S. Holder is a direct shareholder and the Subsidiary PFIC for the QEF rules to apply to both PFICs.

A QEF Election will apply to the tax year for which such QEF Election is timely made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent tax year, the Corporation ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which the Corporation is not a PFIC. Accordingly, if the Corporation becomes a PFIC in another subsequent tax year, the QEF Election will be effective and the U.S. Holder will be subject to the QEF rules described above during any subsequent tax year in which the Corporation qualifies as a PFIC.

The Corporation: (a) will make available to U.S. Holders, upon their written request, information as to its status as a PFIC and the PFIC status of any subsidiary in which the Corporation owns more than 50% of such subsidiary’s total aggregate voting power and (b) for each year in which the Corporation is a PFIC, provide to a U.S. Holder, upon written request, such information and documentation that a U.S. Holder making a QEF Election with respect to the Corporation and such more than 50% owned subsidiary which constitutes a PFIC is reasonably required to obtain for U.S. federal income tax purposes. The Corporation may elect to provide such information on its website. With respect to any Subsidiary PFIC in which the Corporation owns 50% or less of the aggregate voting power, upon the written request of a U.S. Holder acquiring Common Shares, the Corporation will request that such Subsidiary PFIC provide such U.S. Holder with the information that such U.S. Holder requires to report under the QEF rules; provided, however, the Corporation can provide no assurances that such Subsidiary PFIC will provide such information.

A U.S. Holder makes a QEF Election by attaching a completed IRS Form 8621, including a PFIC Annual Information Statement, to a timely filed United States federal income tax return. However, if the Corporation does not provide the required information with regard to the Corporation or any of its Subsidiary PFICs, U.S. Holders will not be able to make a QEF Election for such entity and will continue to be subject to the rules of Section 1291 of the Code discussed above that apply to Non-Electing U.S. Holders with respect to the taxation of gains and excess distributions.

Mark-to-Market Election

A U.S. Holder may make a Mark-to-Market Election only if the Common Shares are marketable stock. The Common Shares generally will be “marketable stock” if the Common Shares are regularly traded on (a) a national securities exchange that is registered with the Securities and Exchange Commission, (b) the national market system established pursuant to section 11A of the U.S. Exchange Act, or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and surveillance requirements, and meets other requirements, and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange effectively promote active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Provided that the Common Shares are “regularly traded” as described in the preceding sentence, the Common Shares are expected to be marketable stock. However, each U.S. Holder should consult its own tax advisor in this matter.

A U.S. Holder that makes a Mark-to-Market Election with respect to its Common Shares generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to such Common Shares. However, if a U.S. Holder does not make a Mark-to-Market Election beginning in the first tax year of such U.S. Holder’s holding period for the Common Shares for which the Corporation is a PFIC and such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Common Shares.

A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which the Corporation is a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Common Shares, as of the close of such tax year over (b) such U.S. Holder’s adjusted tax basis in such Common Shares. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (a) such U.S. Holder’s adjusted tax basis in the Common Shares, over (b) the fair market value of such Common Shares (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

A U.S. Holder that makes a Mark-to-Market Election generally also will adjust such U.S. Holder’s tax basis in the Common Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of Common Shares, a U.S. Holder that makes a Mark-to-Market Election will recognize ordinary income or ordinary loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years). Losses that exceed this limitation are subject to the rules generally applicable to losses provided in the Code and Treasury Regulations.

A U.S. Holder makes a Mark-to-Market Election by attaching a completed IRS Form 8621 to a timely filed United States federal income tax return. A Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the Common Shares cease to be “marketable stock” or the IRS consents to revocation of such election. Each U.S. Holder should consult its own tax advisors regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a U.S. Holder may be eligible to make a Mark-to-Market Election with respect to the Common Shares, no such election may be made with respect to the stock of any Subsidiary PFIC that a U.S. Holder is treated as owning, because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to avoid the application of the default rules of Section 1291 of the Code described above with respect to deemed dispositions of Subsidiary PFIC stock or excess distributions from a Subsidiary PFIC to its shareholder.

Other PFIC Rules

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a U.S. Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Common Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations). However, the specific U.S. federal income tax consequences to a U.S. Holder may vary based on the manner in which Common Shares are transferred.

Certain additional adverse rules may apply with respect to a U.S. Holder if the Corporation is a PFIC, regardless of whether such U.S. Holder makes a QEF Election. For example, under Section 1298(b)(6) of the Code, a U.S. Holder that uses Common Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Common Shares.

Special rules also apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC. Subject to such special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. The rules relating to distributions by a PFIC and their eligibility for the foreign tax credit are complicated, and a U.S. Holder should consult with its own tax advisors regarding the availability of the foreign tax credit with respect to distributions by a PFIC.

The PFIC rules are complex, and each U.S. Holder should consult its own tax advisors regarding the PFIC rules and how the PFIC rules may affect the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Common Shares.

General Rules Applicable to the Ownership and Disposition of Common Shares

The following discussion describes the general rules applicable to the ownership and disposition of the Common Shares but is subject in its entirety to the special rules described above under the heading “Passive Foreign Investment Company Rules.”

Distributions on Common Shares

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to a Common Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current and accumulated “earnings and profits” of the Corporation, as computed for U.S. federal income tax purposes. A dividend generally will be taxed to a U.S. Holder at ordinary income tax rates if the Corporation is a PFIC for the tax year of such distribution or the preceding tax year. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of the Corporation, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder’s tax basis in the Common Shares and thereafter as gain from the sale or exchange of such Common Shares. (See “Sale or Other Taxable Disposition of Common Shares” below). However, the Corporation may not maintain the calculations of its earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder may have to assume that any distribution by the Corporation with respect to the Common Shares will constitute ordinary dividend income. Dividends received on Common Shares by corporate U.S. Holders generally will not be eligible for the “dividends received deduction.” Subject to applicable limitations and provided the Corporation is eligible for the benefits of the Canada-U.S. Tax Convention or the Common Shares are readily tradable on a United States securities market, dividends paid by the Corporation to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the Corporation not be classified as a PFIC in the tax year of distribution or in the preceding tax year. The dividend rules are complex, and each U.S. Holder should consult its own tax advisors regarding the application of such rules.

Sale or Other Taxable Disposition of Common Shares

Upon the sale or other taxable disposition of Common Shares, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the U.S. dollar value of cash received plus the fair market value of any property received and such U.S. Holder’s tax basis in such Common Shares sold or otherwise disposed of. A U.S. Holder’s tax basis in Common Shares generally will be such holder’s U.S. dollar cost for such Common Shares. Gain or loss recognized on such sale or other disposition generally will be long-term capital gain or loss if, at the time of the sale or other disposition, the Common Shares have been held for more than one year.

Preferential tax rates currently apply to long-term capital gain of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gain of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Additional Considerations

Receipt of Foreign Currency

The amount of any distribution paid to a U.S. Holder in foreign currency, or on the sale, exchange or other taxable disposition of Common Shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). A U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who converts or otherwise disposes of the foreign currency after the date of receipt may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should consult its own U.S. tax advisors regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Foreign Tax Credit

Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Common Shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax. Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income that is subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that depend on a U.S. Holder’s particular circumstances. Accordingly, each U.S. Holder should consult its own U.S. tax advisors regarding the foreign tax credit rules.

Backup Withholding and Information Reporting

Under U.S. federal income tax law, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on individuals who are U.S. Holders that hold certain specified foreign financial assets in excess of certain thresholds. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U.S. Holders may be subject to these reporting requirements unless their Common Shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult with their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 8938.

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Common Shares will generally be subject to information reporting and backup withholding tax if a U.S. Holder (a) fails to furnish such U.S. Holder’s correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. Holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax and, under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder should consult its own tax advisors regarding the information reporting and backup withholding rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF COMMON SHARES. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR OWN PARTICULAR CIRCUMSTANCES.

STATUTORY RIGHTS OF WITHDRAWAL AND RESCISSION

Securities legislation in some provinces and territories of Canada provides purchasers of securities with the right to withdraw from an agreement to purchase securities and with remedies for rescission or, in some jurisdictions, revisions of the price, or damages if the prospectus, prospectus supplement, and any amendment relating to securities purchased by a purchaser are not sent or delivered to the purchaser. However, purchasers of Common Shares distributed under an at-the-market distribution by Oncolytics do not have the right to withdraw from an agreement to purchase the Common Shares and do not have remedies of rescission or, in some jurisdictions, revisions of the price, or damages for non-delivery of the prospectus, prospectus supplement, and any amendment relating to the Common Shares purchased by such purchaser because the prospectus, prospectus supplement, and any amendment relating to the Common Shares purchased by such purchaser will not be sent or delivered, as permitted under Part 9 of National Instrument 44-102 - Shelf Distributions.

Securities legislation in some provinces and territories of Canada further provides purchasers with remedies for rescission or, in some jurisdictions, revisions of the price or damages if the prospectus, prospectus supplement, and any amendment relating to securities purchased by a purchaser contains a misrepresentation. Those remedies must be exercised by the purchaser within the time limit prescribed by securities legislation. Any remedies under securities legislation that a purchaser of Common Shares distributed under an at-the-market distribution by Oncolytics may have against Oncolytics or its agents for rescission or, in some jurisdictions, revisions of the price, or damages if the prospectus, prospectus supplement, and any amendment relating to securities purchased by a purchaser contain a misrepresentation will remain unaffected by the non-delivery of the prospectus referred to above.

A purchaser should refer to applicable securities legislation for the particulars of these rights and should consult a legal adviser.

The foregoing statements supersede the information contained in the Prospectus under the heading “Statutory Rights of Withdrawal and Rescission” solely as it relates to the Common Shares being offered by this Prospectus Supplement.

See “Risk Factors”.

This offering is made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States and Canada (“MJDS”), to prepare this Prospectus in accordance with Canadian disclosure requirements. Prospective investors in the United States should be aware that such requirements are different from those of the United States. Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and may not be comparable to financial statements of United States companies.

Prospective investors should be aware that the acquisition of the Securities described herein may have tax consequences both in the United States and in Canada. This Prospectus may not describe these tax consequences fully. You should read the tax discussion in the applicable Prospectus Supplement and consult with your own tax advisor with respect to your own particular circumstances.

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Corporation is incorporated under the laws of Alberta, Canada, that the majority of its officers and directors are residents of Canada, that many of the experts named in this Prospectus are not residents of the United States, and that a substantial portion of the assets of the Corporation and said persons are located outside the United States.

NEITHER THE SEC NOR ANY STATE OR CANADIAN SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED THE SECURITIES OFFERED HEREBY OR DETERMINED IF THIS PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

All shelf information permitted under applicable securities legislation to be omitted from this Prospectus including, without limitation, the information disclosed in the specific terms of any offering of Securities, as discussed above, will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, except in cases where an exemption from such delivery requirements has been obtained. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of such Prospectus Supplement and only for the purposes of the distribution of the Securities to which that Prospectus Supplement pertains.

We may sell the Securities to or through one or more underwriters or dealers purchasing as principals and may also sell the Securities to one or more purchasers directly, through applicable statutory exemptions, or through one or more agents designated by us from time to time. The Securities may be sold from time to time in one or more transactions at fixed prices or not at fixed prices, such as market prices prevailing at the time of sale, prices related to such prevailing market prices or prices to be negotiated with purchasers, which prices may vary as between purchasers and during the period of distribution of the Securities. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent engaged in connection with the offering and sale of such Securities, as well as the method of distribution and the terms of the offering of such Securities, including the initial offering price (in the event the offering is a fixed price distribution), the manner of determining the offering price(s) (in the event the offering is not a fixed price distribution), the net proceeds to us and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms. See “Plan of Distribution”.

In connection with any offering of the Securities other than an “at-the-market distribution” (as defined under applicable Canadian legislation) (unless otherwise specified in the relevant Prospectus Supplement), the underwriters or agents may over-allot or effect transactions that stabilize or maintain the market price of the offered Securities at a level above that which might otherwise prevail on the open market. Such transactions, if commenced, may be interrupted or discontinued at any time. See “Plan of Distribution”.

No underwriter or dealer involved in an “at-the-market distribution” under this Prospectus, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such underwriter or dealer will over-allot securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

Owning the Securities may subject you to tax consequences. This Prospectus and any applicable Prospectus Supplement may not describe the tax consequences fully. You should read the tax discussion in any applicable Prospectus Supplement and consult with your own tax advisor with respect to your own particular circumstances.

Unless otherwise specified in the applicable Prospectus Supplement, the Subscription Receipts, Warrants and Units will not be listed on any securities exchange. There is no market through which these securities may be sold and purchasers may not be able to resell such securities purchased under this Prospectus. This may affect the pricing of such securities in the secondary market, the transparency and availability of trading prices, the liquidity of such securities, and the extent of issuer regulation. See “Forward-Looking Statements” and “Risk Factors”.

THE CORPORATION

Oncolytics Biotech Inc. was incorporated pursuant to the ABCA on April 2, 1998 as 779738 Alberta Ltd.

BUSINESS OF THE CORPORATION

General

Since our inception in April of 1998, Oncolytics Biotech Inc. has been a development stage company and we have focused our research and development efforts related to pelareorep, a systemically administered immuno-oncology (“I-O”) viral agent with the potential to treat a variety of cancers. We have not been profitable since our inception and expect to continue to incur substantial losses as we continue research and development efforts. We do not expect to generate significant revenues until, if and when, pelareorep becomes commercially viable.

Our potential product for human use, pelareorep, an unmodified reovirus, is a first in class systemically administered I-O viral agent for the treatment of solid tumors and hematological malignancies.

Further information regarding the business of the Corporation is contained in the Annual Report under the heading “Item 4 – Information on the Company”, which document is incorporated by reference in this Prospectus. See “Documents Incorporated by Reference.”

Recent Developments

On May 14, 2020 we announced the publication of two abstracts in connection with the upcoming ASCO Virtual Annual Meeting on May 29-31. The first abstract ("Multiple Myeloma Abstract"), which has been accepted as an electronic poster, reports on viral replication, tumor immune responses, and treatment safety in multiple myeloma patients treated with pelareorep in combination with carfilzomib (Kyprolis®). The second abstract ("Pancreatic Cancer Abstract") reports on treatment tolerability and efficacy in pancreatic cancer patients treated with pelareorep, in combination with pembrolizumab (Keytruda®).  

The Multiple Myeloma Abstract highlighted the following:

The Pancreatic Cancer Abstract highlighted the following:

On May 26, 2020, we announced the publication of an electronic-poster (“ePoster”) with clinical data from the Corporation's AWARE-1 window-of-opportunity breast cancer study. The data demonstrates a pelareorep-induced adaptive immune response in the tumor microenvironment (“TME”) and the potential of a predictive biomarker (T cell clonality) to identify patients with breast cancer most likely to respond to pelareorep. The ePoster was published on May 23, 2020 and presented as part of the European Society for Medical Oncology Breast Cancer Virtual Meeting.

Key data and conclusions from this ePoster include:

The results show intravenous delivery of pelareorep reaches the primary breast cancer tumor target.  Importantly, the large increase in CD8+ T cells is prognostic of positive treatment outcomes, and the increased expression of PD-L1 suggests a treatment synergy when combining pelareorep and anti-PD-L1 checkpoint inhibitors, such as Tecentriq®. The correlation between T cell clonality and tumor inflammation continues to show promise across multiple indications and increases our ability to identify patients likely to respond to treatment.

On May 29, 2020, we announced the publication of an ePoster with clinical proof-of-concept data from the Corporation's phase 1b study in carfilzomib-refractory multiple myeloma patients treated with pelareorep in combination with carfilzomib (Kyprolis®). Data presented in this ePoster demonstrates that the pelareorep-carfilzomib combination treatment results in selective replication of pelareorep in cancer cells and beneficial induction of an inflamed tumor environment associated with clinical responses. The ePoster was published and presented as part of the American Society of Clinical Oncology Virtual Annual Meeting.

The ePoster, Oncolytic virus Pelareorep [P] plus Carfilzomib & Dexamethasone [Kd] phase 1 trial in Carfilzomib-refractory patients (NCI9603): responses with cytokine storm was co-authored by Dr. Douglas W. Sborov MD, MS, Assistant Professor, Division of Hematology and Hematologic Malignancies, University of Utah – Huntsman Cancer Institute, and Craig Hofmeister, M.D., MPH, Associate Professor, Department of Hematology and Medical Oncology Emory University School of Medicine, as well as several other colleagues at institutions across the United States. Key data and conclusions from six patients in the study are presented in this ePoster and include:

DESCRIPTION OF SHARE CAPITAL

Authorized Capital

Our authorized capital consists of an unlimited number of Common Shares. The following is a summary of the provisions attached to our Common Shares.

Common Shares

The holders of our Common Shares are entitled to one vote per share at meetings of shareholders, to receive such dividends as declared by the Board and to receive our remaining property and assets upon dissolution or wind up. Our Common Shares are not subject to any future call or assessment and there are no pre-emptive, conversion or redemption rights attached to such shares.

After giving effect to the exercise of all outstanding options to acquire Common Shares and all outstanding share awards granted under the Corporation’s Incentive Share Award Plan, we would have 42,938,570 Common Shares issued and outstanding.

Common Share Purchase Warrants

As of the date hereof, we have 16,443,500 Common Share purchase warrants (the “2017 Warrants”) issued and outstanding. Each 9.5 2017 Warrants entitles the holder to purchase one Common Share until June 1, 2022, at an exercise price of $9.025. The 2017 Warrants are subject to acceleration if the volume weighted average price of the Common Shares equals or exceeds $2.50 for a period of 15 consecutive trading dates.

As of the date hereof, we have 265,757 Common Share purchase warrants (the “2019 Warrants”) issued and outstanding. Each 2019 Warrant entitles the holder to purchase one common share at an exercise price of US$0.90 until August 16, 2024.

In addition, as of the date hereof, the Corporation has outstanding a Common Share purchase warrant (the “Adlai Warrant”) exercisable by the holder thereof until November 14, 2020 to purchase such number of Common Shares as is calculated by dividing US$6,000,000 by the Exercise Price.

For purposes of the Adlai Warrant, the term “Exercise Price” means an amount equal to 120% of the volume weighted average trading price of the Common Shares on the Nasdaq Capital Market (or, if the Common Shares are not then listed on the Nasdaq Capital Market, on the Toronto Stock Exchange) for the five trading days immediately preceding the exercise date.

The Adlai Warrant is subject to a right to call by the Corporation upon the date of the enrollment of the fiftieth (50^th) patient in a Phase 3 Study related to pelareorep.

PLAN OF DISTRIBUTION

We may sell the Securities to or through one or more underwriters or dealers purchasing as principals and we may also sell the Securities to one or more purchasers directly, through applicable statutory exemptions, or through one or more agents designated from time to time. The Securities may be sold from time to time in one or more transactions at fixed prices or not at fixed prices, such as market prices prevailing at the time of sale, prices related to such prevailing market prices or prices to be negotiated with purchasers, which prices may vary as between purchasers and during the period of distribution of the Securities. The Prospectus Supplement relating to a particular offering and sale of Securities will identify each underwriter, dealer or agent engaged in connection with the offering and sale of such Securities, as well as the method of distribution and the terms of the offering and sale of such Securities, including the initial offering price (in the event the offering is a fixed price distribution), the manner of determining the offering price(s) (in the event the offering is not a fixed price distribution), the net proceeds to us and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms. Only underwriters so named in the Prospectus Supplement are deemed to be underwriters in connection with the Securities offered and sold thereby.

If the underwriters purchase Securities from us as principal, the Securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, at market prices prevailing at the time of sale or at prices related to such prevailing market prices. The obligations of the underwriters to purchase such Securities as principal will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all the Securities offered and sold by the Prospectus Supplement if any of such Securities are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to underwriters, dealers or agents may be changed from time to time.

The Securities may be sold from time to time in one or more transactions at a fixed price or prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution. If, in connection with the offering of Securities at a fixed price or prices, the underwriters have made a bona fide effort to sell all of the Securities at the initial offering price fixed in the applicable Prospectus Supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial public offering price fixed in such Prospectus Supplement, in which case the compensation realized by the underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid to us by the underwriters. Any such reduction to the public offering price will not affect the net proceeds received by the Corporation.

The Securities may also be sold directly by us, pursuant to applicable statutory exemptions, at such prices and upon such terms as agreed to by us and the purchaser or through one or more agents designated by us from time to time. Any agent involved in the offering and sale of the Securities in respect of which this Prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement, any agent would be acting on a best efforts basis for the period of its appointment.

We may agree to pay the underwriters a commission for various services relating to the issue and sale of any Securities offered hereby. Any such commission will be paid out of our general funds. Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with us to indemnification by us against certain liabilities under securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.

Any offering of Subscription Receipts, Warrants or Units will be a new issue of securities with no established trading market.
