![Icon Description automatically generated](tm2310426d1_424aimg01.jpg)

**Up to $8,370,000**

**Common Shares**

We have entered into an Equity Distribution Agreement, or the Distribution Agreement, with Canaccord Genuity LLC, or Canaccord, acting as sales agent, on March 27, 2023, relating to our common shares, no par value (the "Common Shares") offered by this prospectus supplement and the accompanying prospectus. Under the Distribution Agreement, we may offer and sell our Common Shares having an aggregate offering price of up to $20.0 million from time to time through Canaccord. However, due to the offering limitations applicable to us under General Instruction I.B.6. of Form S-3 and our public float as of the date of this prospectus supplement, and in accordance with the terms of the Distribution Agreement, we are offering Common Shares having an aggregate gross sales price of up to $8,370,000 pursuant to this prospectus supplement and the accompanying prospectus. If our public float increases such that we may sell additional amounts under the Distribution Agreement and the registration statement of which this prospectus supplement and the accompanying prospectus are a part, we will file another prospectus supplement prior to making additional sales.

Our Common Shares are listed on the Nasdaq Capital Market, or Nasdaq, under the symbol "EDSA." On March 23, 2023, the last reported sale price of our Common Shares on Nasdaq was $1.04 per share.

Sales of our Common Shares, if any, under this prospectus supplement and the accompanying prospectus may be made at market prices by any method permitted by law that is deemed an "at the market offering" as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or the Securities Act. Canaccord is not required to sell any specific number or dollar amount of our Common Shares but will act as sales agent using commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of Nasdaq. There is no arrangement for funds to be received in any escrow, trust or similar arrangement.

Canaccord will be entitled to compensation at a commission rate equal to 3.0% of the gross sales price per share sold under the Distribution Agreement. See "Plan of Distribution" beginning on S-20 for additional information regarding Canaccord's compensation. In connection with the sale of our Common Shares on our behalf, Canaccord may be deemed to be an "underwriter" within the meaning of the Securities Act and the compensation of Canaccord will be deemed to be underwriting commissions or discounts. We have also agreed to provide indemnification and contribution to Canaccord with respect to certain liabilities, including liabilities under the Securities Act and the Securities Exchange Act of 1934, as amended, or the Exchange Act.

As of the date of this prospectus supplement, the aggregate market value of our outstanding Common Shares held by non-affiliates was $25,121,157 based on 20,058,665 Common Shares outstanding, of which 16,207,198 shares were held by non-affiliates, and a price of $1.55 per share, which was the last reported sale price of our Common Shares on Nasdaq on February 2, 2023. As of the date of this prospectus supplement, we have not sold any securities pursuant to General Instruction I.B.6. of Form S-3 during the prior 12 calendar month period that ends on, and includes, the date of this prospectus supplement.

**Investing in our securities involves a high degree of risk. Before making any decision to invest in our securities, you should carefully consider the information disclosed in this this prospectus supplement and the accompanying base prospectus, including the information under "Risk Factors" beginning on page S-6 of this prospectus supplement, as well as the information, including the risk factors, incorporated by reference into this prospectus supplement and the accompanying prospectus as described under the heading "Where You Can Find More Information."**

**NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE ADEQUACY OR ACCURACY OF THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.**

**THE SECURITIES OFFERED BY THIS PROSPECTUS SUPPLEMENT HAVE NOT BEEN QUALIFIED FOR DISTRIBUTION IN CANADA AND MAY NOT BE OFFERED OR SOLD IN CANADA EXCEPT PURSUANT TO AN EXEMPTION FROM THE PROSPECTUS REQUIREMENTS UNDER APPLICABLE CANADIAN SECURITIES LAWS. THE COMPANY HAS NOT FILED AND DOES NOT INTEND TO FILE A CANADIAN PROSPECTUS IN CONNECTION WITH THE SECURITIES OFFERED BY THIS PROSPECTUS SUPPLEMENT.**

**Canaccord Genuity**

The date of this prospectus supplement is March 27, 2023.

**ABOUT THIS PROSPECTUS SUPPLEMENT**

This prospectus supplement and the accompanying base prospectus are part of a registration statement on Form S-3 (File No. 333-266604) that we filed with the Securities and Exchange Commission (the "SEC") utilizing a "shelf" registration process. Each time we conduct an offering to sell securities under the accompanying base prospectus we will provide a prospectus supplement that will contain specific information about the terms of that offering, including the price, the amount of securities being offered and the plan of distribution. The shelf registration statement was initially filed with the SEC on August 5, 2022, and was declared effective on August 12, 2022. This prospectus supplement describes the specific details regarding this offering and may add, update or change information contained in the accompanying base prospectus. The accompanying base prospectus provides general information about us and our securities, some of which, such as the section entitled "Plan of Distribution," may not apply to this offering. This prospectus supplement and the accompanying base prospectus are an offer to sell only the securities offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so. We are not making offers to sell or solicitations to buy our securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making that offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation.

If information in this prospectus supplement is inconsistent with the accompanying base prospectus or the information incorporated by reference with an earlier date, you should rely on this prospectus supplement. This prospectus supplement, together with the accompanying base prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying base prospectus, include all material information relating to this offering. You should assume that the information appearing in this prospectus supplement, the accompanying base prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying base prospectus is accurate only as of the respective dates of those documents. Our business, financial condition, results of operations and prospects may have changed since those dates. **You should carefully read this prospectus supplement, the accompanying base prospectus and the information and documents incorporated by reference herein and therein before making an investment decision. See "Where You Can Find More Information" in this prospectus supplement and in the accompanying base prospectus**.

We have not, and Canaccord has not, authorized anyone to provide you with information that is different from that contained in this prospectus supplement, the accompanying base prospectus or in any free writing prospectus we may authorize to be delivered or made available to you. When you make a decision about whether to invest in our securities, you should not rely upon any information other than the information contained in or incorporated by reference into this prospectus supplement, the accompanying base prospectus or in any free writing prospectus that we may authorize to be delivered or made available to you. Neither the delivery of this prospectus supplement and the accompanying base prospectus nor the sale of our securities means that the information contained in this prospectus supplement, the accompanying base prospectus or any free writing prospectus is correct after the date of the respective dates of such documents.

For investors outside the United States: We have not, and Canaccord has not, taken any action that would permit this offering or possession or distribution of this prospectus supplement or the accompanying base prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement or the accompanying base prospectus must inform themselves about, and observe any restrictions relating to, the offering of the securities covered hereby and the distribution of this prospectus supplement and the accompanying base prospectus outside the United States. This offering is not available to a resident of Canada or a person or company in Canada. See the section entitled "Plan of Distribution" in this prospectus supplement.

This prospectus supplement and the accompanying base prospectus contain summaries of certain provisions contained in some of the documents described herein, but reference is made to the actual documents for complete information. All of the summaries are qualified in their entirety by the full text of the actual documents, some of which have been filed or will be filed with the SEC and incorporated by reference herein. See "Where You Can Find More Information" in this prospectus supplement. We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference into this prospectus supplement or the accompanying base prospectus were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you.

**SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS**

Except for historical information, this prospectus supplement, the accompanying prospectus and any documents we incorporate by reference contain forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Such forward-looking statements include, among others, those statements including the words "believes," "anticipates," "expects," "intends," "estimates," "plans," and words of similar import. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements.

Forward-looking statements are based on our current expectations and assumptions regarding our business, potential target businesses, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Our actual results may differ materially from those contemplated by the forward-looking statements. We caution you therefore that you should not rely on any of these forward-looking statements as statements of historical fact or as guarantees or assurances of future performance. You should understand that many important factors, in addition to those discussed in this prospectus supplement, the accompanying prospectus and any documents we incorporate by reference, could cause our results to differ materially from those expressed in the forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include changes in local, regional, national, or global political, economic, business, competitive, market (supply and demand) and regulatory conditions and the following:

&nbsp;&nbsp;&nbsp;&nbsp;· our ability to obtain funding for our operations;

&nbsp;&nbsp;&nbsp;&nbsp;· our estimates regarding our expenses, revenues, anticipated capital requirements and our needs for additional financing;

&nbsp;&nbsp;&nbsp;&nbsp;· the timing of the commencement, progress and receipt of data from any of our preclinical and clinical trials;

&nbsp;&nbsp;&nbsp;&nbsp;· the expected results of any preclinical or clinical trial and the impact on the likelihood or timing of any regulatory approval;

&nbsp;&nbsp;&nbsp;&nbsp;· the therapeutic benefits, effectiveness and safety of our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;· the timing or likelihood of regulatory filings and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;· changes in our strategy or development plans;

&nbsp;&nbsp;&nbsp;&nbsp;· the volatility of our Common Share price;

&nbsp;&nbsp;&nbsp;&nbsp;· the rate and degree of market acceptance and clinical utility of any future products;

&nbsp;&nbsp;&nbsp;&nbsp;· the effect of competition;

&nbsp;&nbsp;&nbsp;&nbsp;· our ability to protect our intellectual property as well as comply with the terms of license agreements with third parties;

&nbsp;&nbsp;&nbsp;&nbsp;· our ability to identify, develop and commercialize additional products or product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;· reliance on key personnel; and

&nbsp;&nbsp;&nbsp;&nbsp;· general changes in economic or business conditions, including those caused by Covid-19 and its variants.

Other sections of this prospectus supplement, the accompanying prospectus and any documents we incorporate by reference describe additional risk factors that could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risk factors and uncertainties emerge from time to time, and it is not possible for our management to predict all risk factors and uncertainties, nor are we able to assess the impact of all of these risk factors on our business or the extent to which any risk factor, or combination of risk factors, may cause actual results to differ materially from those contained in any forward-looking statements. These risks and others described under the section "Risk Factors" in this prospectus supplement, the accompanying prospectus and any documents we incorporate by reference are not exhaustive.

Given these uncertainties, you are cautioned not to place undue reliance on such forward-looking statements. We disclaim any obligation to update any such factors or to publicly announce the result of any revisions to any of the forward-looking statements contained herein to reflect future events or developments.

**SUMMARY**

*The following summary highlights selected information contained elsewhere in or incorporated by reference into this prospectus supplement and the accompanying prospectus. The summary may not contain all of the information that you should consider before investing in our Common Shares. You should read this entire prospectus supplement and the accompanying prospectus carefully, including "Risk Factors" contained in this prospectus supplement and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus, before making an investment decision. This prospectus supplement may add to, update or change information in the accompanying prospectus. See the "Risk Factors" section of this prospectus supplement beginning on page S-6 for a discussion of the risks involved in investing in our securities.*

**Our Company**

We are a biopharmaceutical company developing innovative ways to treat inflammatory and immune-related diseases.

Our approach is to acquire, develop and commercialize drug candidates based on mechanisms of action that have demonstrated proof-of-concept in human subjects. We prioritize our efforts on disease indications where there is compelling scientific rationale, no approved therapies or where there are unmet medical needs, and where there are large addressable market opportunities, among other factors. We have multiple late-stage product candidates in our development pipeline.

Our most advanced drug candidate is EB05, a monoclonal antibody developed for acute and chronic disease indications that involve dysregulated innate immunity responses. EB05 inhibits toll-like receptor 4, a key immune signaling protein and an important mediator of inflammation. We are currently evaluating EB05 as a potential treatment for Acute Respiratory Distress Syndrome (ARDS), a life-threatening form of respiratory failure. In September 2022, we reported final results from the Phase 2 part of a Phase 2/Phase 3 study of EB05 in ARDS patients who were hospitalized for Covid-19-related respiratory disease. Among the findings, EB05 demonstrated statistically significant mortality reductions in critically ill hospitalized patients treated with EB05 plus Standard of Care treatment. Based in part of these findings, the U.S. Food and Drug Administration granted us Fast Track designation. We are currently enrolling patients in the Phase 3 part of the EB05 study.

In addition to EB05, we are developing product candidates for a number of chronic dermatological and inflammatory conditions. We recently reported preliminary, topline results from a Phase 2b clinical study evaluating multiple concentrations of our drug candidate, EB01, as a monotherapy for moderate-to-severe chronic Allergic Contact Dermatitis, a common occupational skin condition. Among the preliminary findings, 1.0% EB01 cream demonstrated statistically significant improvement over placebo for the primary endpoint and a key secondary endpoint. We are preparing for an End of Phase 2 meeting with FDA following full analysis. In January 2023, Health Canada approved our clinical trial application for our EB06 monoclonal antibody candidate to conduct a future Phase 2 study in vitiligo, a common autoimmune disorder that causes skin to lose its color in patches. We are also preparing an investigational new drug application in the United States for our EB07 product candidate to conduct a future Phase 2 study in systemic sclerosis, an autoimmune rheumatic disorder that causes fibrosis (scarring/hardening) of skin and internal organs.

**Corporate Information**

We are a British Columbia, Canada corporation founded in 2007 and operate through our wholly owned subsidiaries, Edesa Biotech Research, Inc., an Ontario, Canada corporation and Edesa Biotech USA, Inc., a California, USA corporation. In June 2019, we acquired the Ontario corporation through a reverse acquisition and changed our name to Edesa Biotech, Inc. Our Common Shares are traded on Nasdaq under the symbol "EDSA." Our executive offices are located at 100 Spy Court, Markham, Ontario L3R 5H6 Canada and our telephone number at this location is (289) 800-9600. Our website address is www.edesabiotech.com.

**RISK FACTORS**

*Before making an investment decision, you should carefully consider the risks described in this prospectus supplement, together with all of the other information incorporated by reference into this prospectus supplement and the accompanying prospectus, including the risks described in our most recent Annual Report on Form 10-K , *as amended,* as well as any amendments thereto reflected in subsequent filings with the SEC, including our audited consolidated financial statements and corresponding management's discussion and analysis. The risks mentioned below are presented as of the date of this prospectus supplement and we expect that these will be updated from time to time in our periodic and current reports filed with or furnished to the SEC, as applicable, which are incorporated herein by reference. Please refer to these subsequent reports for additional information relating to the risks associated with investing in our Common Shares.*

*Our business, financial condition or results of operations could be materially adversely affected by any of these risks. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. The trading price of our Common Shares could decline due to any of these risks, and you may lose all or part of your investment. This prospectus supplement, the accompanying prospectus and the incorporated documents also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks mentioned below. Forward-looking statements included in this prospectus supplement are based on information available to us on the date hereof, and all forward-looking statements in documents incorporated by reference are based on information available to us as of the date of each such document. We are under no obligation to update or alter such forward-looking statements whether as a result of new information, future events or otherwise, other than as required by applicable securities legislation.*

**Risks Relating to This Offering**

***You will experience immediate dilution in the book value per Common Share you purchase in this offering.***

Because the price per Common Share being offered hereby is substantially higher than the book value per Common Share, you will suffer substantial dilution in the net tangible book value of the Common Shares purchase in this offering. Based on the assumed public offering price of $1.04 per share, which was the last reported sale price of our Common Shares on Nasdaq on March 23, 2023, and assuming that we sell all $8,370,000 of Common Shares under this prospectus supplement, and after deducting commissions and estimated aggregate offering expenses payable by us, if you purchase Common Shares in this offering, you will experience immediate and substantial dilution of $0.46 per share in the net tangible book value of the Common Shares. See the section titled "Dilution" below for a more detailed discussion of the dilution you will incur if you purchase Common Shares in this offering.

***Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use the proceeds effectively.***

We intend to use the net proceeds from the sale of Common Shares by us in this offering for general corporate purposes, which may include working capital, capital expenditures and research and development and manufacturing expenses. Our management will have broad discretion as to the application of the net proceeds from this offering and could use them for purposes other than those contemplated at the time of this offering, as described below in the section entitled "Use of Proceeds," or in ways that do not necessarily improve our operating results or enhance the value of our Common Shares. Our shareholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Our failure to use these funds effectively could have a material adverse effect on our business and could cause the price of our securities to decline.

***It is not possible to predict the aggregate proceeds resulting from sales made under the Distribution Agreement.***

Subject to certain limitations in the Distribution Agreement and compliance with applicable law, we have the discretion to deliver a placement notice to Canaccord at any time throughout the term of the Distribution Agreement. The number of shares that are sold through Canaccord after delivering a placement notice will fluctuate based on a number of factors, including the market price of our Common Shares during the sales period, the limits we set with Canaccord in any applicable placement notice, and the demand for our Common Shares during the sales period. Because the price per share of each share sold will fluctuate during the sales period, it is not currently possible to predict the aggregate proceeds to be raised in connection with those sales.

***The Common Shares offered hereby will be sold in "at the market offerings," and investors who buy shares at different times will likely pay different prices.***

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and number of shares sold in this offering. In addition, subject to the final determination by our board of directors, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

***You may experience future dilution as a result of future equity offerings.***

In order to raise additional capital, we may in the future offer additional Common Shares or other securities convertible into or exchangeable for our Common Shares at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in another offering at a price per share that is less than the price per share paid by the investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing shareholders. The price per share at which we sell additional shares of our Common Shares, or securities convertible or exchangeable into Common Shares, in future transactions may be higher or lower than the price per share paid by investors in this offering. If any of the above should occur, our shareholders, including investors who purchase Common Shares in this offering, will experience additional dilution, and any such issuances may result in downward pressure on the price of our Common Shares.

***We do not currently intend to pay dividends on our Common Shares in the foreseeable future, and consequently, any gains from an investment in our Common Shares will likely depend on appreciation in the price of our Common Shares.***

We have never declared or paid cash dividends on our Common Shares and do not anticipate paying any cash dividends to holders of our Common Shares in the foreseeable future. Consequently, investors must rely on sales of their Common Shares after price appreciation, which may never occur, as the only way to realize any future gains on their investments. There is no guarantee that our Common Shares will appreciate in value or even maintain the price at which the shareholders have purchased their shares.

**USE OF PROCEEDS**

We may issue and sell our Common Shares having aggregate sales proceeds of up to $8,370,000 from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that we will sell any shares under or fully utilize the Distribution Agreement with Canaccord as a source of financing.

We currently expect to use the net proceeds, if any, from the sale of Common Shares offered hereby for general corporate purposes which may include working capital, capital expenditures and research and development and manufacturing expenses.

This expected use of the net proceeds from this offering represents our intentions based upon our current plans and business conditions, and our management will retain broad discretion as to the ultimate allocation of the proceeds. We may temporarily invest funds that we do not immediately need for these purposes in investment securities or use them to make payments on our borrowings.

**DIVIDEND POLICY**

We have never declared nor paid dividends on our securities. We currently expect to retain future earnings, if any, for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Any future determination to pay dividends on our securities is subject to the discretion of our board of directors and will depend upon various factors, including, without limitation, our results of operations and financial condition.

**DILUTION**

If you invest in our Common Shares, your interest will be diluted immediately to the extent of the difference between the between the price per share you pay in this offering and the as-adjusted net tangible book value per Common Share after this offering.

The net tangible book value of our Common Shares as of December 31, 2022 was approximately $8.02 million, or approximately $0.41 per Common Share. Net tangible book value per share represents the amount of our total tangible assets less total liabilities divided by the total number of our Common Shares outstanding as of December 31, 2022.

After giving effect to the sale by us of Common Shares in the aggregate amount of $8,370,000 at an assumed offering price of $1.04 per share, the last reported sale price of our Common Shares on Nasdaq on March 23, 2023, and after deducting commissions and estimated offering expenses, our net tangible book value as of December 31, 2022 would have been approximately $15.86 million, or $0.58 per share. This represents an immediate increase in net tangible book value of $0.17 per share to existing shareholders and an immediate dilution of $0.46 per share to new investors purchasing Common Shares in this offering. The following table illustrates this dilution:

---

| | | |
|:---|:---|:---|
| Assumed offering price per Common Share |  | $1.04 |
| Net tangible book value per Common Share as of December 31, 2022 | $0.41 |  |
| Increase in as adjusted net tangible book value per Common Share attributable to the offering | $0.17 |  |
| As adjusted net tangible book value per Common Share as of December 31, 2022 after giving effect to this offering |  | $0.58 |
| Dilution per Common Share to new investors participating in this offering |  | $0.46 |

---

The table above assumes for illustrative purposes that an aggregate of 8,048,076 shares are sold during the term of the Distribution Agreement with Canaccord at a price of $1.04 per share, the last reported sale price of our Common Shares on Nasdaq on March 23, 2023, for aggregate gross proceeds of $8,370,000. The shares subject to the Distribution Agreement are being sold from time to time at various prices. This information is supplied for illustrative purposes only and may differ based on the actual offering price and the actual number of shares offered.

The foregoing table is based on 19,353,351 of our Common Shares outstanding as of December 31, 2022, and excludes, as of such date, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 2,206,961 of our Common Shares issuable upon exercise of outstanding options granted under our equity incentive plans at a weighted average exercise price of $4.61 per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 418,990 of our Common Shares available for issuance or future grant pursuant to our equity incentive plan; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 6,343,283 of our Common Shares issuable upon exercise of outstanding warrants at a weighted average exercise price of $2.84 per share.

To the extent that outstanding exercisable options or warrants are exercised, you may experience further dilution. In addition, we may need to raise additional capital and to the extent that we raise additional capital by issuing equity or convertible debt securities your ownership will be further diluted.

**CERTAIN TAX MATTERS**

THE FOLLOWING SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY PARTICULAR INVESTOR. CONSEQUENTLY, PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS FOR ADVICE AS TO THE TAX CONSEQUENCES OF AN INVESTMENT IN THE SECURITIES OFFERED BY THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUS HAVING REGARD TO THEIR PARTICULAR CIRCUMSTANCES.

**Material U.S. Federal Income Tax Considerations for U.S. Holders**

The following discussion is a summary of the material U.S. federal income tax consequences applicable to the purchase, ownership and disposition of Common Shares being offered by this prospectus supplement and the accompanying prospectus by a U.S. Holder (as defined below), but does not purport to be a complete analysis of all potential U.S. federal income tax effects.

This summary is based on the Internal Revenue Code of 1986, as amended (the "Code"), final temporary and proposed U.S. Treasury regulations promulgated thereunder (the "Regulations"), IRS rulings and judicial decisions in effect on the date of this prospectus supplement. All of these are subject to change, possibly with retroactive effect, or different interpretations. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive basis. 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.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to particular U.S. Holders in light of their specific circumstances (for example, U.S. Holders subject to the alternative minimum tax or the Medicare contribution tax on net investment income under the Code) or to holders that may be subject to special rules under U.S. federal income tax law, including, without limitation:

● dealers in stocks, securities or currencies;

● securities traders that use a mark-to-market accounting method;

● banks, underwriters and financial institutions;

● insurance companies;

● regulated investment companies;

● passive foreign investment companies;

● real estate investment trusts;

● tax-exempt organizations;

● retirement plans, individual plans, individual retirement accounts and tax-deferred accounts;

● partnerships or other pass-through entities for U.S. federal income tax purposes and their partners or members;

● persons holding Common Shares as part of a hedging or conversion transaction straddle or other integrated or risk reduction transaction;

● persons who or that are, or may become, subject to the expatriation provisions of the Code;

● persons who are subject to taxing jurisdictions other than, or in addition to, the United States;

● persons whose functional currency is not the U.S. dollar;

● persons who acquired Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services;

● persons who are subject to special tax accounting rules with respect to our Common Shares; and

● direct, indirect or constructive owners of 10% or more of the total combined voting power of all classes of our voting stock or 10% or more of the total value of shares of all classes of our stock.

This summary also does not discuss any aspect of state, local or foreign law, or estate or gift tax law as applicable to U.S. Holders. In addition, this discussion is limited to U.S. Holders purchasing Common Shares pursuant to this prospectus supplement and that will hold such Common Shares as capital assets. For purposes of this summary, "U.S. Holder" means a beneficial holder of Common Shares who or that for U.S. federal income tax purposes is:

● an individual citizen or resident alien of the U.S.;

● a corporation or other entity classified as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the U.S., any state thereof or the District of Columbia;

● an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

● a trust, if (a) a court within the U.S. is able to exercise primary supervision over the administration of such trust and one or more "U.S. persons" (within the meaning of the Code) have the authority to control all substantial decisions of the trust, or (b) a valid election is in effect to be treated as a U.S. person for U.S. federal income tax purposes.

PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE TAX CONSEQUENCES DESCRIBED BELOW TO THEIR PARTICULAR SITUATIONS AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS.

*Tax Consequences if we are a Passive Foreign Investment Company*

A foreign corporation will be classified as a PFIC for any taxable year in which, after taking into account the income and assets of the corporation and that of certain subsidiaries pursuant to applicable "look-through rules," either (i) at least 75% of its gross income is "passive income" (the "income test") or (ii) at least 50% of the average quarterly value of its assets is attributable to assets which produce passive income or are held for the production of passive income (the "asset test"). Passive income generally includes dividends, interest, rents and royalties (other than certain rents and royalties derived in the active conduct of a trade or business), annuities and gains from assets that produce passive income. For purposes of the asset test, the value of the Company's assets is expected to be based, in part, on the quarterly average of the fair market value of such assets. If a non-U.S. corporation owns at least 25% by value of the stock of another corporation, the non-U.S. corporation is treated for purposes of the income and asset tests as (i) owning its proportionate share of the assets of the other corporation and as (ii) receiving directly its proportionate share of the other corporation's income.

Under applicable attribution rules, if we are a PFIC, U.S. Holders will be deemed to own their proportionate share of any of our subsidiaries which is also a PFIC (a "Subsidiary PFIC"), and will be subject to the adverse PFIC rules discussed below on their proportionate share of any (i) distribution on the shares of a Subsidiary PFIC and (ii) disposition or deemed disposition of shares of a Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC. 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. 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.

The determination of whether we are, or will be, a PFIC for a taxable year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to various interpretations. Although the matter is not free from doubt, we do not believe that we or our subsidiary were a PFIC during our September 30, 2022 taxable year and will not likely be a PFIC during our September 30, 2023 taxable year. Because PFIC status is based on our income, assets and activities for the entire taxable year, and our market capitalization, it is not possible to determine whether we will be characterized as a PFIC for the September 30, 2023 taxable year until after the close of the taxable year. The tests for determining PFIC status are subject to a number of uncertainties. These tests are applied annually, and it is difficult to accurately predict future income, assets and activities relevant to this determination. In addition, because the market price of our Common Shares is likely to fluctuate, the market price may affect the determination of whether we will be considered a PFIC. 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. There can be no assurance that we will not be considered a PFIC for any taxable year (including our September 30, 2023 taxable year). Prospective investors should consult their tax advisors regarding the Company's PFIC status.

If the Company is classified as a PFIC for any taxable year during which a U.S. Holder owns Common Shares, the U.S. Holder, absent certain elections (including the mark-to-market and QEF elections described below), will generally be subject to adverse rules (regardless of whether the Company continues to be classified as a PFIC) with respect to (i) any "excess distributions" (generally, any distributions received by the U.S. Holder on the Common Shares in a taxable year that are greater than 125% of the average annual distributions received by the U.S. Holder in the three preceding taxable years or, if shorter, the U.S. Holder's holding period for the Common Shares) and (ii) any gain realized on the sale or other disposition of the Common Shares.

Under these adverse rules (a) the excess distribution or gain will be allocated ratably over the U.S. Holder's holding period, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which the Company is classified as a PFIC will be taxed as ordinary income and (c) the amount allocated to each of the other taxable years during which the Company was classified as a PFIC will be subject to tax at the highest rate of tax in effect for the applicable category of taxpayer for that year and an interest charge will be imposed with respect to the resulting tax attributable to each such other taxable year. A U.S. Holder that is not a corporation will be required to treat any such interest paid as "personal interest," which is not deductible.

To the extent a distribution on our Common Shares, does not constitute an excess distribution to a U.S. Holder under the adverse rules described above, such U.S. holder generally will be required to include the amount of such distribution in gross income as a dividend to the extent of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) that are not allocated to excess distributions, and will not be eligible for the reduced rates applicable to "qualified dividend income" with respect to such distribution.

U.S. Holders can avoid the adverse rules described above in part by making a mark-to-market election with respect to the Common Shares, provided that the Common Shares are "marketable." The Common Shares will be marketable if they are "regularly traded" on a "qualified exchange" or other market within the meaning of applicable Regulations. For this purpose, the Common Shares generally will be considered to be regularly traded during any calendar year during which they are traded, other than in *de minimis* quantities, on at least 15 days during each calendar quarter. The Common Shares are currently listed on the Nasdaq, which constitutes a qualified exchange; however, there can be no assurance that the Common Shares will be treated as regularly traded for purposes of the mark-to-market election on a qualified exchange. If the Common Shares were not regularly traded on the Nasdaq or were delisted from the Nasdaq and were not traded on another qualified exchange for the requisite time period described above, the mark-to-market election would not be available.

A U.S. Holder that makes a mark-to-market election must include in gross income, as ordinary income, for each taxable year an amount equal to the excess, if any, of the fair market value of the U.S. Holder's Common Shares at the close of the taxable year over the U.S. Holder's adjusted tax basis in the Common Shares. An electing U.S. Holder may also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder's adjusted tax basis in the Common Shares over the fair market value of the Common Shares at the close of the taxable year, but this deduction is allowable only to the extent of any net mark-to-market gains previously included in income. A U.S. Holder that makes a mark-to-market election generally 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. Gains from an actual sale or other disposition of the Common Shares will be treated as ordinary income, and any losses incurred on a sale or other disposition of the Common Shares will be treated as ordinary losses to the extent of any net mark-to-market gains previously included in income. Losses that exceed this limitation are subject to the rules generally applicable to losses provided in the Code and Regulations (see "Material U.S. Federal Income Tax Considerations — Sale, Exchange or Other Taxable Disposition of Common Shares" below). Amounts treated as ordinary income will not be eligible for the preferential tax rates applicable to "qualified dividend income" or long-term capital gains. A mark-to-market election is not permitted for the shares of any Subsidiary PFIC.

If we are classified as a PFIC for any taxable year in which a U.S. Holder owns Common Shares, but before a mark-to-market election is made, the adverse PFIC rules described above will apply to any mark-to-market gain recognized in the year the election is made. Otherwise, a mark-to-market election will be effective for the taxable year for which the election is made and all subsequent taxable years. The election cannot be revoked without the consent of the IRS unless the Common Shares cease to be marketable, in which case the election is automatically terminated.

In some cases, a shareholder of a PFIC can avoid the interest charge and the other adverse PFIC consequences described above by making a QEF election to be taxed currently on its share of the PFIC's undistributed income. We may not be able to satisfy the record keeping requirements that apply to a QEF and to supply requesting U.S. Holders with the information that such U.S. Holders are required to report under the QEF rules.

A U.S. Holder that makes a timely and effective QEF election for the first tax year in which its holding period of its Common Shares begins generally will not be subject to the adverse PFIC consequences described above with respect to its Common Shares. Rather, 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 Company's net capital gain, which will be taxed as long-term capital gain to such U.S. Holder, and (b) the Company's ordinary earnings, which will be taxed as ordinary income to such U.S. Holder, in each case regardless of which such amounts are actually distributed to the U.S. Holder by the Company. Generally, "net capital gain" is the excess of (i) net long-term capital gain over (ii) 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 timely and effective QEF election with respect to the Company generally (a) may receive a tax-free distribution from us to the extent that such distribution represents "earnings and profits" 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.

If a U.S. Holder does not make a timely and effective QEF election for the first tax year in which its holding period of its Common Shares begins, the U.S. Holder may still be able to make a timely and effective QEF election in a subsequent tax year if such U.S. Holder meets certain requirements and makes a "purging" election to recognize gain (which will be subject to the adverse rules described 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 continue to be subject to the adverse PFIC consequences described above with respect to its Common Shares.

The QEF election is made on a holder-by-holder basis. Once made, a QEF election will apply to the tax year for which the QEF election is made and to all subsequent tax years, unless the QEF election is invalidated or terminated or the IRS consents to revocation of the QEF election. In addition, if a U.S. Holder makes a QEF election, the QEF election will remain in effect (although it will not be applicable) during those tax years in which we are not a PFIC.

Under Section 1291(f) of the Code, the IRS has issued proposed 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.

If finalized in their current form, the proposed Regulations applicable to PFICs would be effective for transactions occurring on or after April 1, 1992. Because the proposed Regulations have not yet been adopted in final form, they are not currently effective, and there is no assurance that they will be adopted in the form and with the effective date proposed. Nevertheless, the IRS has announced that, in the absence of final Regulations, taxpayers may apply reasonable interpretations of the Code provisions applicable to PFICs and that it considers the rules set forth in the proposed Regulations to be reasonable interpretations of those Code provisions. U.S. Holders should consult their own tax advisors about the potential applicability of the proposed Regulations.

Certain additional adverse rules may apply with respect to a U.S. Holder if we are 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 our Common Shares as security for a loan will, except as may be provided in 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 by 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 their own tax advisor regarding the availability of the foreign tax credit with respect to distributions by a PFIC.

If the Company is a PFIC in any year with respect to a U.S. Holder, the U.S. Holder will be required to file an annual information return on IRS Form 8621, *Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund,* regarding their ownership of Common Shares, distributions received on Common Shares and any gain realized on the disposition of Common Shares.

If the Company is classified as a PFIC and then ceases to be so classified, a U.S. Holder may make an election (a "deemed sale election") to be treated for U.S. federal income tax purposes as having sold such U.S. Holder's Common Shares on the last day of the taxable year of the Company during which it was a PFIC. A U.S. Holder that made a deemed sale election would then cease to be treated as owning stock in a PFIC by reason of ownership of Common Shares. Any gain recognized, however, as a result of making the deemed sale election would be subject to the adverse rules described above and loss would not be recognized.

Lastly, if we are not treated as a PFIC, and you paid taxes as if we were a PFIC, then you may be able to claim a refund for taxes you paid in excess of the taxes you actually owed. If you do not timely make such a refund claim, then your refund will be disallowed and you will bear more taxes than you actually owe.

Prospective investors should consult their tax advisors regarding the potential application of the PFIC regime and any reporting obligations to which they may be subject under that regime.

*Taxation of Distributions*

Subject to the PFIC rules discussed above, any distributions paid by us out of current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), before reduction for any Canadian withholding tax paid with respect thereto, will generally be taxable to a U.S. Holder as foreign source dividend income, and generally will not be eligible for the dividends received deduction generally allowed to corporations.

Distributions in excess of current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of the U.S. Holder's adjusted tax basis in the Common Shares and, thereafter, as capital gain. We do not, however, intend to calculate our earnings and profits under U.S. federal income tax principles. Therefore, U.S. Holders should expect that any distribution from us generally will be treated for U.S. federal income tax purposes as a dividend. Prospective investors should consult their own tax advisors with respect to the appropriate U.S. federal income tax treatment of any distribution received from us.

Dividends paid to non-corporate U.S. Holders by us in a taxable year in which we are treated as a PFIC, or in the immediately following taxable year, will not be eligible for the special reduced rates normally applicable to long-term capital gains. In all other taxable years, dividends paid by us should be taxable to a non-corporate U.S. Holder at the special reduced rates normally applicable to long-term capital gains, provided that certain conditions are satisfied (including a minimum holding period requirement). We believe we were not a PFIC for the September 30, 2022 taxable year. However, no assurance can be provided that we will not be classified as a PFIC for September 30, 2023 and, therefore, no assurance can be provided that a U.S. Holder will be able to claim a reduced rate for dividends paid in the September 30, 2023 or September 30, 2024 years (if any). Please see "Material U.S. Federal Income Tax Considerations — Tax Consequences if we are a Passive Foreign Investment Company" above for a more detailed discussion.

Under current law, payments of dividends by us to non-Canadian investors are generally subject to a 25% Canadian withholding tax. The rate of withholding tax applicable to U.S. Holders that are eligible for benefits under the Canada-United States Tax Convention (the "Convention") is reduced to a maximum of 15%. This reduced rate of withholding will not apply if the dividends received by a U.S. Holder are effectively connected with a permanent establishment of the U.S. Holder in Canada. For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of Canadian taxes withheld by the Company, and as then having paid over the withheld taxes to the Canadian taxing authorities. As a result of this rule, the amount of dividend income included in gross income for U.S. federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than the amount of cash actually received (or receivable) by the U.S. Holder from the Company with respect to the payment.

Subject to certain limitations, a U.S. Holder will generally be entitled, at the election of the U.S. Holder, to a credit against its U.S. federal income tax liability, or a deduction in computing its U.S. federal taxable income, for Canadian income taxes withheld by us. 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. For purposes of the foreign tax credit limitation, dividends paid by us generally will constitute foreign source income in the "passive category income" basket rather than the "general category income" basket). A U.S. Holder will be denied a foreign tax credit with respect to Canadian income tax withheld from dividends received with respect to our Common Shares to the extent the U.S. Holders has not held the Common Shares for at least 16 days of the 30-day period beginning on the date which is 15 days before the ex-dividend date or to the extent the U.S. Holder is under an obligation to make related payments with respect to substantially similar or related property. Any days during which a U.S. Holder has substantially diminished its risk of loss on our Common Shares are not counted toward meeting the 16-day holding period required by the statute The foreign tax credit rules are complex and prospective investors should consult their tax advisors concerning the availability of the foreign tax credit in their particular circumstances.

Dividends paid in Canadian dollars will be included in the gross income of a U.S. Holder in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date the U.S. Holder (actually or constructively) receives the dividend, regardless of whether such Canadian dollars are actually converted into U.S. dollars at that time. If the Canadian dollars received are not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the Canadian dollars equal to their U.S. dollar value on the date of receipt. Gain or loss, if any, realized on a sale or other disposition of the Canadian dollars will generally be U.S. source ordinary income or loss to a U.S. Holder.

We generally do not pay any dividends and do not anticipate paying any dividends in the foreseeable future.

*Sale, Exchange or Other Taxable Disposition of Common Shares*

Subject to the PFIC rules discussed above, upon a sale, exchange or other taxable disposition of Common Shares, a U.S. Holder generally will recognize capital gain or loss for U.S. federal income tax purposes equal to the difference, if any, between the amount realized on the sale, exchange or other taxable disposition and the U.S. Holder's adjusted tax basis in the Common Shares.

If the U.S. Holder receives Canadian dollars in the transaction, the amount realized will be the U.S. dollar value of the Canadian dollars received, which is determined for cash basis taxpayers on the settlement date for the transaction and for accrual basis taxpayers on the trade date (although accrual basis taxpayers can also elect the settlement date).

This capital gain or loss will be long-term capital gain or loss if the U.S. Holder's holding period in the Common Shares exceeds one year. The deductibility of capital losses is subject to limitations. Any gain or loss will generally be U.S. source for U.S. foreign tax credit purposes.

*Information Reporting and Backup Withholding*

In general, information reporting for U.S. federal income tax purposes should apply to distributions made on our securities within the United States to a U.S. Holder (other than an exempt recipient) and to the proceeds from sales and other dispositions of our securities by a U.S. Holder (other than an exempt recipient) to or through a U.S. office of a broker. Payments made (and sales and other dispositions effected at an office) outside the United States will be subject to information reporting in limited circumstances. In addition, certain information concerning a U.S. Holder's adjusted tax basis in securities it owns and adjustments to that tax basis and whether any gain or loss with respect to such securities is long term or short term also may be required to be reported to the IRS.

In addition, Section 6038D of the Code generally requires certain individuals who are U.S. Holders (and possibly certain entities that have U.S. Holder owners) to file IRS Form 8938, *Statement of Specified Foreign Financial Assets,* to report the ownership of specified foreign financial assets if the total value of those assets exceeds an applicable threshold amount (subject to certain exceptions). For these purposes, a specified foreign financial asset includes not only a financial account (as defined for these purposes) maintained by a foreign financial institution, but also 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, provided that the asset is not held in an account maintained by a financial institution. The minimum applicable threshold amount is generally $50,000 in the aggregate, but this threshold amount varies depending on whether the individual lives in the U.S., is married, files a joint income tax return with his or her spouse, and on certain other factors. Certain domestic entities that are U.S. Holders may also be required to file IRS Form 8938, *Statement of Specified Foreign Financial Assets,* if both (i) such entities are owned at least 80% by an individual who is a U.S. citizen or U.S. tax resident (or in some cases, by a nonresident alien who meets certain criteria) or are trusts with beneficiaries that are such individuals and (ii) more than 50% of their income consists of certain passive income or more than 50% of their assets is held for the production of such income. U.S. Holders are urged to consult with their tax advisors regarding their reporting obligations, including the requirement to file IRS Form 8938, *Statement of Specified Foreign Financial Assets*.

U.S. Holders who transfer more than $100,000 to us in a 12-month period (and/or who become owners of 10% or more of our securities) will be required to file IRS Form 926, *Return by U.S. Transferor of Property to a Foreign Corporation*, and U.S. Holders who become holder of more than 10% of our securities may also have to file IRS Form 5471, *Information Return of U.S. Persons With Respect to Certain Foreign Corporations*, in each case reporting transfers of cash or other property to us and information relating to the U.S. Holder and us. Substantial penalties may be imposed upon a U.S. Holder that fails to comply with these filing requirements. U.S. Holders should consult their own tax advisors about the need to file either of these forms. See also the discussion, above, regarding IRS Form 8621, *Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund*.

Backup withholding of U.S. federal income tax, currently at a rate of 24%, generally will apply to dividends paid on our securities to a U.S. Holder (other than an exempt recipient) and the proceeds from sales and other dispositions of our securities by a U.S. Holder (other than an exempt recipient), in each case who:

● fails to provide an accurate taxpayer identification number;

● is notified by the IRS that backup withholding is required; or

● in certain circumstances, fails to comply with applicable certification requirements.

A non-U.S. Holder generally may eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Rather, the amount of any backup withholding will be allowed as a credit against a U.S. Holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is timely furnished to the IRS.

Holders are urged to consult their own tax advisors regarding the application of backup withholding and the availability of and procedures for obtaining an exemption from backup withholding in their particular circumstances.

**Certain Canadian Federal Income Tax Considerations for U.S. Shareholders**

The following is a general summary, as of the date hereof, of the principal Canadian federal income tax considerations generally applicable to a holder who acquires Common Shares pursuant to this prospectus supplement and who, at all relevant times, for the purposes of the *Income Tax Act* (Canada) (the "Tax Act"), (i) is not resident, or deemed to be resident, in Canada, (ii) deals at arm's length with, and is not affiliated with, the Company or the sales agent, (iii) beneficially owns the Common Shares as capital property, (iv) does not use or hold the Common Shares in the course of carrying on, or otherwise in connection with, a business or a part of a business carried on or deemed to be carried on in Canada, and (v) is not an insurer that carries on an insurance business in Canada and elsewhere or an "authorized foreign bank" within the meaning of the Tax Act (a "Non-resident Holder"). Generally, the Common Shares will be considered to be capital property to a Non-resident Holder unless such securities are held in the course of carrying on a business of trading or dealing in securities or has acquired them or deemed to have acquired them in a transaction or transactions considered to be an adventure or concern in the nature of trade.

This summary is based upon the current provisions of the Tax Act, the regulations thereunder (the "Regulations") and the Convention and the Company's understanding of the current administrative policies and assessing practices of the Canada Revenue Agency ("CRA") made publicly available prior to the date hereof. It also takes into account all proposed amendments to the Tax Act and the Regulations publicly released by the Minister of Finance (Canada) ("Tax Proposals") prior to the date hereof, and assumes that all such Tax Proposals will be enacted as currently proposed. No assurance can be given that the Tax Proposals will be enacted in the form proposed or at all. This summary does not otherwise take into account or anticipate any changes in law, whether by way of legislative, judicial or administrative action or interpretation, nor does it take into account tax laws of any province or territory of Canada or of any other jurisdiction outside Canada.

**This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular holder and no representation with respect to the federal income tax consequences to any particular holder or prospective holder is made. The tax consequences to a holder will depend on the holder's particular circumstances. Accordingly, holders should consult with their own tax advisors for advice with respect to their own particular circumstances.**

For purposes of the Tax Act, all amounts relating to the acquisition, holding and disposition of Common Shares, including dividends, adjusted cost base and proceeds of disposition, must generally be determined in Canadian dollars using the applicable exchange rate quoted by the Bank of Canada for the relevant day or such other rate of exchange that is acceptable to the CRA.

***Dividends***

Amounts paid or credited or deemed to be paid or credited as, on account or in lieu of payment, or in satisfaction of, dividends on the Common Shares to a Non-resident Holder will be subject to Canadian withholding tax at the rate of 25% on the gross amount of such dividends unless the rate is reduced under the provisions of an applicable income tax treaty or convention between Canada and the country of residence of the Non-resident Holder. For example, under the Convention, the rate of Canadian withholding tax on dividends paid or credited by the Company to a Non-resident Holder who is a resident of the United States for purposes of the Convention, is fully entitled to the benefits of the Convention, and beneficially owns such dividends is generally 15% unless the beneficial owner is a corporation that owns at least 10% of the voting stock of the Company at that time, in which case the rate of Canadian withholding tax is reduced to 5%.

***Dispositions***

A Non-resident Holder will generally not be subject to tax under the Tax Act on any capital gain realized on a disposition or deemed disposition of Common Shares, unless the Common Shares constitute "taxable Canadian property" to the Non-resident Holder at the time of disposition and the Non-resident Holder is not entitled to relief under an applicable income tax treaty or convention between Canada and the country of residence of the Non-resident Holder. In addition, capital losses arising on the disposition or deemed disposition of Common Shares will not be recognized under the Tax Act unless the Common Shares constitutes "taxable Canadian property" to the Non-resident Holder for purposes of the Tax Act.

Generally, Common Shares will not constitute taxable Canadian property to a Non-resident Holder provided the Common Shares are listed on a designated stock exchange, as defined in the Tax Act (which currently includes the Nasdaq) at the time of the disposition, unless at any time during the 60-month period immediately preceding the disposition, (a) 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 described in (B) holds a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any series or class of the capital stock of the Company and (b) more than 50% of the fair market value of Common Shares was derived directly or indirectly from one or any combination of (i) real or immovable property situated in Canada, (ii) "Canadian resource properties" (as defined in the Tax Act), (iii) "timber resource properties" (as defined in the Tax Act) and (iv) options in respect of, or interests in, or for civil law rights in property described in (i) to (iii), whether or not the 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 in certain circumstances.

Non-resident Holders whose Common Shares may be taxable Canadian property should consult their own tax advisors regarding the tax and compliance considerations that may be relevant to them. There may be additional considerations not described herein in respect of the acquisition, disposition, or holding of the Common Shares by a Non-resident Holder. Such Non-resident Holders should consult their own tax advisors having regard to their particular circumstances.

**PLAN OF DISTRIBUTION**

We have entered into an Equity Distribution Agreement, or the Distribution Agreement, with Canaccord, under which we may offer and sell our Common Shares having an aggregate offering price of up to $20.0 million from time to time through Canaccord, acting as sales agent. However, due to the offering limitations applicable to us under General Instruction I.B.6. of Form S-3 and our public float as of the date of this prospectus supplement, and in accordance with the terms of the Distribution Agreement, we are offering Common Shares having an aggregate gross sales price of up to $8,370,000 pursuant to this prospectus supplement and the accompanying prospectus. If our public float increases such that we may sell additional amounts under the Distribution Agreement and the registration statement of which this prospectus supplement and the accompanying prospectus are a part, we will file another prospectus supplement prior to making additional sales. The Distribution Agreement has been filed as an exhibit to a Current Report on Form 8-K. If authorized by us in writing, Canaccord may also purchase our Common Shares as principal.

Upon delivery of a placement notice to Canaccord and subject to the terms and conditions of the Distribution Agreement, Canaccord may offer and sell our Common Shares by any method permitted by law deemed to be an "at the market offering," as defined in Rule 415(a)(4) promulgated under the Securities Act. We may instruct Canaccord not to sell our Common Shares if the sales cannot be effected at or above the price designated by us from time to time. We or Canaccord may suspend the offering of our Common Shares upon notice and subject to other conditions.

Canaccord will provide to us written confirmation following the close of trading on Nasdaq each day on which our Common Shares are sold under the Distribution Agreement. Each confirmation will include the number of Common Shares sold on such day, the net proceeds to the Company, and the compensation payable by us to Canaccord with respect to such sales.

We will pay Canaccord commissions for its services in acting as sales agent in the sale of our Common Shares. Canaccord is entitled to compensation at a commission rate of 3.0% of the gross sales price per share sold by Canaccord under the Distribution Agreement. Because there is no minimum offering amount required as a condition to close this 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 Canaccord for certain reasonable and documented expenses, including fees and disbursements of its counsel, up to an amount of $100,000 and up to $5,000 per due diligence update. We estimate that the total expenses of the offering payable by us, excluding any commissions and the reimbursement payable to Canaccord under the terms of the Distribution Agreement, will be approximately $180,000.

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

Canaccord will use commercially reasonable efforts, consistent with their sales and trading practices, to solicit offers to purchase our Common Shares under the terms and subject to the conditions set forth in the Distribution Agreement. In connection with the sale of our Common Shares on our behalf, Canaccord may be deemed to be an "underwriter" within the meaning of the Securities Act, and the compensation of Canaccord (and its partners, members, directors, officers, employees and agents) may be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to Canaccord against certain liabilities, including civil liabilities under the Securities Act.

The offering of our Common Shares pursuant to the Distribution Agreement will terminate upon the termination of the Distribution Agreement as permitted therein. Canaccord and we each have the right, by giving written notice as specified in the Distribution Agreement, to terminate the Distribution Agreement in each party's sole discretion at any time.

Canaccord and its respective affiliates may in the future provide various investment banking, commercial banking and other financial services for us, our subsidiaries and our affiliates, for which services they may in the future receive customary fees. To the extent required by Regulation M, Canaccord will not engage in any market-making activities involving our Common Shares while the offering is ongoing under this prospectus supplement.

**Canadian Securities Matters**

The Common Shares are being distributed pursuant to a prospectus exemption under applicable Canadian securities laws on the basis that the Common Shares are being distributed outside Canada. Canaccord has agreed not to engage in any solicitation or sale of Common Shares to a person or company who is a resident of Canada or a person or company in Canada.

**LEGAL MATTERS**

Certain legal matters relating to the offering of Common Shares under this prospectus supplement will be passed upon for us by Fasken Martineau DuMoulin, LLP, Toronto, Ontario, Canada with respect to matters of Canadian law and by Lowenstein Sandler LLP, New York, New York with respect to matters of U.S. law. Goodwin Procter LLP, New York, New York is acting as counsel for Canaccord in connection with certain legal matters relating to the Common Shares offered by this prospectus supplement.

**CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS**

This prospectus and the documents incorporated by reference in this prospectus contain, and our officers and representatives may from time to time make, "forward-looking statements," which include information relating to future events, future financial performance, financial projections, strategies, expectations, competitive environment and regulation. Words such as "may," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," "goal," "seek," "project," "strategy," "likely," and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements are neither historical facts, nor should they be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management's good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;· our ability
 to obtain funding for our operations;

&nbsp;&nbsp;&nbsp;&nbsp;· our estimates
 regarding our expenses, revenues, anticipated capital requirements and our needs for additional
 financing;

&nbsp;&nbsp;&nbsp;&nbsp;· the timing
 of the commencement, progress and receipt of data from any of our preclinical and clinical
 trials;

&nbsp;&nbsp;&nbsp;&nbsp;· the expected
 results of any preclinical or clinical trial and the impact on the likelihood or timing of
 any regulatory approval;

&nbsp;&nbsp;&nbsp;&nbsp;· the therapeutic
 benefits, effectiveness and safety of our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;· the timing
 or likelihood of regulatory filings and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;· changes in
 our strategy or development plans;

&nbsp;&nbsp;&nbsp;&nbsp;· the volatility
 of our common share price;

&nbsp;&nbsp;&nbsp;&nbsp;· the rate and
 degree of market acceptance and clinical utility of any future products;

&nbsp;&nbsp;&nbsp;&nbsp;· the effect
 of competition;

&nbsp;&nbsp;&nbsp;&nbsp;· our ability
 to protect our intellectual property as well as comply with the terms of license agreements
 with third parties;

&nbsp;&nbsp;&nbsp;&nbsp;· our ability
 to identify, develop and commercialize additional products or product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;· reliance on
 key personnel; and

&nbsp;&nbsp;&nbsp;&nbsp;· general changes
 in economic or business conditions, including those caused by COVID-19 and its variants.

The foregoing does not represent an exhaustive list of matters that may be covered by the forward-looking statements contained herein and in the documents incorporated by reference herein or risk factors that we are faced with that may cause our actual results to differ from those anticipate in our forward-looking statements. Factors that may affect our results include, but are not limited to, the risks and uncertainties discussed in the "Risk Factors" section on page 4 of this prospectus, in our Annual Report on Form 10-K or in other reports we file with the Securities and Exchange Commission.

Moreover, new risks regularly emerge and it is not possible for our management to predict or articulate all risks we face, nor can we assess the impact of all risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ from those contained in any forward-looking statements. The Private Securities Litigation Reform Act of 1995 and Section 27A of the Securities Act of 1933, as amended, do not protect any forward-looking statements that we make in connection with this offering. All forward-looking statements included in this prospectus and in the documents incorporated by reference in this prospectus are based on information available to us on the date of this prospectus or the date of the applicable document incorporated by reference. Except to the extent required by applicable laws or rules, we undertake no obligation to publicly update or revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained above and throughout this prospectus and in the documents incorporated by reference in this prospectus. We qualify all of our forward-looking statements by these cautionary statements.

**Overview**

We are a biopharmaceutical company focused on acquiring, developing and commercializing clinical-stage drugs for inflammatory and immune-related diseases with clear unmet medical needs. Our two lead product candidates, EB05 and EB01, are in later stage clinical studies.

EB05 is a monoclonal antibody therapy that we are developing as a treatment for Acute Respiratory Distress Syndrome (ARDS), a life-threatening form of respiratory failure. EB05 inhibits toll-like receptor 4 (TLR4), a key immune signaling protein and an important mediator of inflammation that has been shown to be activated by SARS-COV2 as well as other respiratory infections such as influenza. In multiple third-party studies, high serum levels of alarmins (damage signaling molecules) that bind to and activate TLR4 are associated with poor outcomes and disease progression in ARDS patients. Since EB05 has demonstrated the ability to block signaling irrespective of the presence or concentration of the various molecules that frequently bind with TLR4, we believe that EB05 could ameliorate TLR4-mediated inflammation cascades in ARDS patients, thereby reducing lung injury, ventilation rates and mortality. In September 2021, an independent data and safety monitoring board preemptively unblinded the Phase 2 part of a Phase 2/3 study of EB05 in hospitalized COVID-19 patients and identified "a clinically important" mortality benefit. The monitoring board further recommended continuation of the study into a Phase 3 confirmatory trial, which is ongoing.

In addition to EB05, we are developing an sPLA2 inhibitor, designated as EB01, as a topical treatment for chronic allergic contact dermatitis (ACD), a common, potentially debilitating condition and occupational illness. EB01 employs a novel, non-steroidal mechanism of action and in two clinical studies has demonstrated statistically significant improvement of multiple symptoms in ACD patients. EB01 is currently being evaluated in a Phase 2b clinical study.

In addition to our current clinical programs, we intend to expand the utility of our technologies and clinical-stage assets across other indications.

**RISK FACTORS**

Before purchasing any of the securities you should carefully consider the risk factors incorporated by reference in this prospectus from our Annual Report on Form 10-K for the fiscal year ended September 30, 2021 and any subsequent updates described in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, as well as the risks, uncertainties and additional information set forth in our SEC reports on Forms 10-K, 10-Q and 8-K and in the other documents incorporated by reference in this prospectus. For a description of these reports and documents, and information about where you can find them, see "Additional Information" and "Incorporation of Certain Information By Reference." Additional risks not presently known or that we presently consider to be immaterial could subsequently materially and adversely affect our financial condition, results of operations, business and prospects.

**USE OF PROCEEDS**

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of the securities will be used for working capital and general corporate purposes. When particular securities are offered, the prospectus supplement relating to that offering will set forth our intended use of the net proceeds received from the sale of those securities we sell. Pending the application of the net proceeds for these purposes, we expect to invest the proceeds in short-term, interest-bearing instruments or other investment-grade securities.

**THE SECURITIES WE MAY OFFER**

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all of the material terms and provisions of the various types of securities that we may offer. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. If we indicate in the applicable prospectus supplement, the terms of the securities may differ from the terms we have summarized below. We may also include in the prospectus supplement information about material Canadian or United States federal income tax considerations relating to the securities, and the securities exchange, if any, on which the securities will be listed.

We may sell from time to time, in one or more offerings:

● common shares;

● preferred shares;

● debt securities;

● subscription rights to purchase common shares, preferred shares or debt securities;

● warrants to purchase shares of common shares or preferred shares; and

● units consisting of any combination of the securities listed above.

In this prospectus, we refer to the common shares, preferred shares, debt securities, subscription rights, warrants and units collectively as "securities." The total dollar amount of all securities that we may sell will not exceed $150,000,000.

If we issue debt securities at a discount from their original stated principal amount, then, for purposes of calculating the total dollar amount of all securities issued under this prospectus, we will treat the initial offering price of the debt securities as the total original principal amount of the debt securities.

This prospectus may not be used to consummate a sale of securities unless it is accompanied by a prospectus supplement.

**DESCRIPTION OF CAPITAL SHARES**

We are authorized to issue an unlimited number of common shares and preferred shares, no par value. As of August 4, 2022, there were 15,462,287 common shares outstanding and no preferred shares outstanding.

The following summary description of our capital shares is based on the provisions of our Notice of Articles and Articles. This information is qualified entirely by reference to the applicable provisions of our Articles and the British Columbia *Business Corporations Act*. For information on how to obtain copies of our Notice of Articles and Articles, which are exhibits to the registration statement of which this prospectus is a part, see "Incorporation of Certain Information by Reference."

**Common Shares**

The holders of our common shares are entitled to one vote for each share held of record on all matters submitted to a vote of the shareholders. Our shareholders do not have cumulative voting rights in the election of directors. Subject to preferences that may be applicable to any outstanding preferred shares, the holders of common shares are entitled to receive ratably only those dividends as may be declared by our board of directors out of legally available funds. Upon our liquidation, dissolution or winding up, holders of our common shares are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred shares. Holders of common shares have no preemptive or other subscription or conversion rights. There are no redemption or sinking fund provisions applicable to our common shares. Common shares outstanding, and to be issued, are, and will be, fully paid and non-assessable. Additional shares of authorized common shares may be issued, as authorized by our board of directors from time to time, without shareholder approval, except as may be required by applicable stock exchange requirements.

**Preferred Shares**

Pursuant to our Notice of Articles and Articles, and the provisions of the British Columbia *Business Corporations* Act, our board of directors has the authority, without further action by the shareholders (unless such shareholder action is required by applicable law or the rules of the Nasdaq Stock Market), to designate and issue an unlimited number of preferred shares in one of more series, to establish from time to time the number of shares to be included in each such series, to fix the designations, powers, preferences and rights of the shares of each wholly unissued series, and any qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding. Preferred shares, if issued, will be fully paid and non-assessable.

The board of directors' authority to determine the terms of any such preferred shares include, without limitation: (i) the designation of each series and the number of preferred shares that will constitute each such series; (ii) the dividend rate or amount, if any, for each series; (iii) the price at which, and the terms and conditions on which, the preferred shares of each series may be redeemed, if such shares are redeemable; (iv) the terms and conditions, if any, upon which preferred shares of such series may be converted into shares of other classes or series of shares of the Company, or other securities; and (v) the maturity date, if any, for each such series; but no such special rights or restriction shall contravene any other provision of Part 26 of the Articles of the Company.

We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, a Notice of Alteration to the Notice of Articles of the Company, which will be filed in accordance with British Columbia law and which shall describe the designations, preferences, limitations, restrictions and rights of the series of preferred shares that we are offering before the issuance of that series of preferred shares. This description will include:

&nbsp;&nbsp;&nbsp;&nbsp;· the title and
 stated value;

&nbsp;&nbsp;&nbsp;&nbsp;· the number
 of shares we are offering;

&nbsp;&nbsp;&nbsp;&nbsp;· the liquidation
 preference per share;

&nbsp;&nbsp;&nbsp;&nbsp;· the purchase
 price;

&nbsp;&nbsp;&nbsp;&nbsp;· the rate and
 amount of dividends (whether cumulative, non-cumulative or partially cumulative), the dates
 and places of payment thereof;

&nbsp;&nbsp;&nbsp;&nbsp;· the
 consideration for, and the terms and conditions of, any purchase for cancellation or redemption
 thereof (including redemption after a fixed term or at a premium);

&nbsp;&nbsp;&nbsp;&nbsp;· the
 conversion or exchange rights;

&nbsp;&nbsp;&nbsp;&nbsp;· the
 terms and conditions of any share purchase plan or sinking fund;

&nbsp;&nbsp;&nbsp;&nbsp;· the
 restrictions respecting payment of dividends on, or the repayment of capital in respect of,
 any other share of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;· the
 voting rights and restrictions, if any;

&nbsp;&nbsp;&nbsp;&nbsp;· any
 listing of the preferred shares on any securities exchange or market;

&nbsp;&nbsp;&nbsp;&nbsp;· whether
 the preferred shares will be convertible into our common shares, and, if applicable, the
 conversion price, or how it will be calculated, and the conversion period;

&nbsp;&nbsp;&nbsp;&nbsp;· preemptive
 rights, if any;

&nbsp;&nbsp;&nbsp;&nbsp;· restrictions
 on transfer, sale or other assignment, if any;

&nbsp;&nbsp;&nbsp;&nbsp;· whether
 interests in the preferred shares will be represented by depositary shares;

&nbsp;&nbsp;&nbsp;&nbsp;· a
 discussion of any material Canadian or United States federal income tax considerations applicable
 to the preferred shares;

&nbsp;&nbsp;&nbsp;&nbsp;· the
 relative ranking and preferences of the preferred shares as to dividend rights and rights
 if we liquidate, dissolve or wind up our affairs;

&nbsp;&nbsp;&nbsp;&nbsp;· any
 limitations on the issuance of any class or series of preferred shares ranking senior to
 or on a parity with the series of preferred shares as to dividend rights and rights if we
 liquidate, dissolve or wind up our affairs; and

&nbsp;&nbsp;&nbsp;&nbsp;· any
 other specific terms, preferences, rights or limitations of, or restrictions on, the preferred
 shares.

The issuance of preferred shares may or may not have a dilutive effect on the voting rights of shareholders owning common shares, depending on the rights and preferences set by the board of directors. Preferred shares may be issued quickly with terms designed to delay or prevent a change in control of our company or make removal of management more difficult. However, except for such rights relating to the election of directors on a default in payment of dividends as may be attached to any series of the preferred shares by the board of directors or in connection with convertible preferred shares, the holders of preferred shares shall not be entitled, as such, to receive notice of, or to attend or vote at, any general meeting of shareholders of the Company. Section 61 of the *British Columbia Business Corporations Act* provides that the special rights attached to preferred shares may not be prejudiced or interfered with unless the shareholders holding such class of shares consent to such matter by a special resolution of such holders of preferred shares. Additionally, the issuance of preferred shares may have the effect of decreasing the market price of our common shares.

**CERTAIN PROVISIONS OF OUR CHARTER DOCUMENTS AND BRITISH COLUMBIA LAW**

**Anti-takeover Provisions of our Articles of Incorporation**

In addition to the board of directors' ability to issue preferred shares, our Articles, as amended, contain other provisions that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of our Company unless such takeover or change in control is approved by our board of directors. These provisions include advance notice procedures for shareholder proposals and a supermajority vote requirement for business combinations.

**Advance Notice Procedures for Shareholder Proposals**

Effective October 31, 2013, our board of directors adopted an advance notice policy (the "Advance Notice Policy") with immediate effect for the purpose of providing our shareholders, directors and management with a clear framework for nominating our directors in connection with any annual or special meeting of shareholders. The Advance Notice Policy was approved by the shareholders at our annual meeting on February 13, 2014.

*Purpose of the Advance Notice Policy*. Our directors are committed to: (i) facilitating an orderly and efficient annual general or, where the need arises, special meeting, process; (ii) ensuring that all shareholders receive adequate notice of the director nominations and sufficient information with respect to all nominees; and (iii) allowing shareholders to register an informed vote having been afforded reasonable time for appropriate deliberation. The purpose of the Advance Notice Policy is to provide our shareholders, directors and management with a clear framework for nominating directors. The Advance Notice Policy fixes a deadline by which holders of record of our common shares must submit director nominations to the Company prior to any annual or special meeting of shareholders and sets forth the information that a shareholder must include in the notice to the Company for the notice to be in proper written form in order for any director nominee to be eligible for election at any annual or special meeting of shareholders.

*Terms of the Advance Notice Policy*. The Advance Notice Policy provides that advance notice to the Company must be made in circumstances where nominations of persons for election to our board of directors are made by shareholders of the Company other than pursuant to: (i) a "proposal" made in accordance with Division 7 of Part 5 of the British Columbia Business Corporations Act, or the Act; or (ii) a requisition of the shareholders made in accordance with section 167 of the Act. Among other things, the Advance Notice Policy fixes a deadline by which holders of record of our common shares must submit director nominations to the secretary of the Company prior to any annual or special meeting of shareholders and sets forth the specific information that a shareholder must include in the written notice to the secretary of the Company for an effective nomination to occur. No person will be eligible for election as a director of the Company unless nominated in accordance with the provisions of the Advance Notice Policy.

In the case of an annual meeting of shareholders, notice to the Company must be made not less than 30 nor more than 65 days prior to the date of the annual meeting; provided, however, that in the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 10th day following such public announcement.

In the case of a special meeting of shareholders (which is not also an annual meeting), notice to the Company must be made not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.

Our board of directors may, in its sole discretion, waive any requirement of the Advance Notice Policy.

**Provisions of British Columbia Law Governing Business Combinations**

All provinces of Canada have adopted National Instrument 62-104 entitled "*Take-Over Bids and Issuer Bids*" and related forms to harmonize and consolidate take-over bid and issuer bid regimes nationally ("NI 62-104"). The Canadian Securities Administrators, or CSA, have also issued National Policy 62-203 entitled "*Take-Over Bids and Issuer Bids*" (the "National Policy") which contains regulatory guidance on the interpretation and application of NI 62-104 and on the conduct of parties involved in a bid. The National Policy and NI 62-104 are collectively referred to as the "Bid Regime." The National Policy does not have the force of law, but is an indication by the CSA of what the intentions and desires of the regulators are in the areas covered by their policies. Unlike some regimes where the take-over bid rules are primarily policy-driven, in Canada the regulatory framework for take-over bids is primarily rules-based, which rules are supported by policy.

A "take-over bid" or "bid" is an offer to acquire outstanding voting or equity securities of a class made to any person who is in one of the provinces of Canada or to any securityholder of an offeree issuer whose last address as shown on the books of a target is in such province, where the securities subject to the offer to acquire, together with the securities "beneficially owned" by the offeror, constitute in the aggregate 20% or more of the outstanding securities of that class of securities at the date of the offer to acquire. For the purposes of the Bid Regime, a security is deemed to be "beneficially owned" by an offeror as of a specific date if the offeror is the beneficial owner of a security convertible into the security within 60 days following that date, or has a right or obligation permitting or requiring the offeror, whether or not on conditions, to acquire beneficial ownership of the security within 60 days by a single transaction or a series of linked transactions. Offerors are also subject to early warning requirements, where an offeror who acquires "beneficial ownership of", or control or direction over, voting or equity securities of any class of a reporting issuer or securities convertible into, voting or equity securities of any class of a target that, together with the offeror's securities, would constitute 10% or more of the outstanding securities of that class must promptly publicly issue and file a news release containing certain prescribed information, and, within two business days, file an early warning report containing substantially the same information as is contained in the news release.

In addition, where an offeror is required to file an early warning report or a further report as described and the offeror acquires or disposes of beneficial ownership of, or the power to exercise control or direction over, an additional 2% or more of the outstanding securities of the class, or disposes of beneficial ownership of outstanding securities of the class below 10%, the offeror must issue an additional press release and file a new early warning report. Any material change in a previously filed early warning report also triggers the issuance and filing of a new press release and early warning report. During the period commencing on the occurrence of an event in respect of which an early warning report is required and terminating on the expiry of one business day from the date that the early warning report is filed, the offeror may not acquire or offer to acquire beneficial ownership of any securities of the class in respect of which the early warning report was required to be filed or any securities convertible into securities of that class. This requirement does not apply to an offeror that has beneficial ownership of, or control or direction over, securities that comprise 20% of more of the outstanding securities of the class.

Related party transactions, issuer bids and insider bids are subject to additional regulation that may differ depending on the particular jurisdiction of Canada in which it occurs.

 with respect to book-entry procedures, if any;

 of such warrants, including terms, procedures and limitations relating to the exchange and

**Transfer Agent and Registrar**

The transfer agent and registrar, if any, for any warrants will be set forth in the applicable prospectus supplement.

**DESCRIPTION OF DEBT SECURITIES**

This prospectus describes certain general terms and provisions of debt securities that we may offer. The debt securities may be issued pursuant to, in the case of senior debt securities, a senior indenture, and in the case of subordinated debt securities, a subordinated indenture, in each case in the forms filed as exhibits to this registration statement, which we refer to as the "indentures." The indentures will be entered into between us and a trustee to be named prior to the issuance of any debt securities, which we refer to as the "trustee." The indentures will not limit the amount of debt securities that can be issued thereunder and will provide that the debt securities may be issued from time to time in one or more series pursuant to the terms of one or more securities resolutions or supplemental indentures creating such series.

We have summarized below the material provisions of the indentures and the debt securities or indicated which material provisions will be described in the related prospectus supplement for any offering of debt securities. These descriptions are only summaries, and you should refer to the relevant indenture for the particular offering of debt securities itself which will describe completely the terms and definitions of the offered debt securities and contain additional information about the debt securities.

All references in this section, "Description of Debt Securities," to "Edesa," the "Company", "we", "us", "our", the "registrant" or similar words are solely to Edesa Biotech, Inc., and not to its subsidiaries.

**Terms**

When we offer to sell a particular series of debt securities, we will describe the specific terms of the securities in a prospectus supplement. The prospectus supplement will set forth the following terms, as applicable, of the debt securities offered thereby:

&nbsp;&nbsp;&nbsp;&nbsp;· the designation, aggregate principal amount, currency or composite
 currency and denominations;

· the price at which such debt securities will be issued and, if an index
 formula or other method is used, the method for determining amounts of principal or interest;

· the maturity date and other dates, if any, on which principal will
 be payable;

· whether or not the debt securities will be secured or unsecured, and
 the terms of any secured debt;

· whether the debt securities rank as senior debt, senior subordinated
 debt, subordinated debt or any combination thereof, and the terms of any subordination;

· the interest rate (which may be fixed or variable), if any;

· the date or dates from which interest will accrue and on which interest
 will be payable, and the record dates for the payment of interest;

· the manner of paying principal and interest;

· the place or places where principal and interest will be payable;

· the terms of any mandatory or optional redemption by us or any third
 party including any sinking fund;

· the terms of any conversion or exchange;

· the terms of any redemption at the option of holders or put by the
 holders;

· any tax indemnity provisions;

· if the debt securities provide that payments of principal or interest
 may be made in a currency other than that in which debt securities are denominated, the manner for determining such payments;

· the portion of principal payable upon acceleration of a Discounted
 Debt Security (as defined below);

· whether and upon what terms debt securities may be defeased;

· any events of default or covenants in addition to or in lieu of those
 set forth in the indentures;

· provisions for electronic issuance of debt securities or for debt securities
 in uncertificated form; and

· any additional provisions or other special terms not inconsistent with
 the provisions of the indentures, including any terms that may be required or advisable under United States or other applicable laws
 or regulations, or advisable in connection with the marketing of the debt securities.

Debt securities of any series may be issued in registered or bearer form and, if registered, may be certificated or uncertificated form, in such denominations as specified in the terms of the series**.** 

Securities may be issued under the indentures as Discounted Debt Securities to be offered and sold at a substantial discount from the principal amount thereof. Special Canadian or United States federal income tax and other considerations applicable thereto will be described in the prospectus supplement relating to such Discounted Debt Securities. "Discounted Debt Security" means a security where the amount of principal due upon acceleration is less than the stated principal amount.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance and the offering price, and will be consolidated with, and form a single series with, such outstanding debt securities.

**Ranking**

The senior debt securities will rank equally with all of our other senior and unsubordinated debt. Our secured debt, if any, will be effectively senior to the senior debt securities to the extent of the value of the assets securing such debt. The subordinated debt securities will be subordinate and junior in right of payment to all of our present and future senior indebtedness to the extent and in the manner described in the prospectus supplement and as set forth in the board resolution, officer's certificate or supplemental indenture relating to such offering.

We have only a shareholder's claim on the assets of our subsidiaries. This shareholder's claim is junior to the claims that creditors of our subsidiaries have against our subsidiaries. Holders of our debt securities will be our creditors and not creditors of any of our subsidiaries. As a result, all the existing and future liabilities of our subsidiaries, including any claims of their creditors, will effectively be senior to the debt securities with respect to the assets of our subsidiaries. In addition, to the extent that we issue any secured debt, the debt securities will be effectively subordinated to such secured debt to the extent of the value of the assets securing such secured debt.

The debt securities will be obligations exclusively of Edesa. To the extent that our ability to service our debt, including the debt securities, may be dependent upon the earnings of our subsidiaries, our ability to do so will be dependent on the ability of our subsidiaries to distribute those earnings to us as dividends, loans or other payments.

**Certain Covenants**

Any covenants that may apply to a particular series of debt securities will be described in the prospectus supplement relating thereto.

**Successor Obligor**

The indentures provide that, unless otherwise specified in the securities resolution or supplemental indenture establishing a series of debt securities, we shall not consolidate or amalgamate with or merge into, or transfer all or substantially all of our assets to, any person in any transaction in which we are not the survivor, unless:

&nbsp;&nbsp;&nbsp;&nbsp;· the person
 is organized under the laws of the United States or Canada or a jurisdiction within the United
 States or Canada;

&nbsp;&nbsp;&nbsp;&nbsp;· the person
 assumes by supplemental indenture all of our obligations under the relevant indenture, the
 debt securities and any coupons;

&nbsp;&nbsp;&nbsp;&nbsp;· immediately
 after the transaction no Default (as defined below) exists; and

&nbsp;&nbsp;&nbsp;&nbsp;· we deliver
 to the trustee an officers' certificate and opinion of counsel stating that the transaction
 complies with the foregoing requirements.

In such event, the successor will be substituted for us, and thereafter all of our obligations under the relevant indenture, the debt securities and any coupons will terminate.

**Exchange of Debt Securities**

Registered debt securities may be exchanged for an equal aggregate principal amount of registered debt securities of the same series and date of maturity in such authorized denominations as may be requested upon surrender of the registered debt securities at an agency of the company maintained for such purpose and upon fulfillment of all other requirements of such agent.

**Default and Remedies**

Unless the securities resolution or supplemental indenture establishing the series otherwise provides (in which event the prospectus supplement will so state), an "Event of Default" with respect to a series of debt securities will occur if:

(1) we default in any payment of interest on any debt
 securities of such series when the same becomes due and payable and the default continues for a period of 30 days;

(2) we default in the payment of the principal
 and premium, if any, of any debt securities of such series when the same becomes due and payable at maturity or upon redemption,
 acceleration or otherwise and such default shall continue for five or more days;

(3) we default in the performance of any of
 our other agreements applicable to the series and the default continues for 30 days after the notice specified below;

(4) a court of competent jurisdiction enters
 an order or decree under any Insolvency Law (as defined below) that:

&nbsp;&nbsp;&nbsp;&nbsp;(A) is for relief against us in an involuntary case,

(B) appoints a Custodian (as defined below) for us or
 for all or substantially all of our property, or

(C) orders the liquidation of us, and the order or decree
 remains unstayed and in effect for 90 days;

(5) we pursuant to or within the meaning of
 any Insolvency Law:

(A) commence a voluntary case,

(B) consent to the entry of an order for relief against
 us in an involuntary case,

(C) consent to the appointment of a Custodian for us or
 for all or substantially all of our property, or

(D) make a general assignment for the benefit of our creditors;
 or

(6) there occurs any other Event of Default
 provided for in such series.

The term "Insolvency Law" means the applicable law as prescribed under the governing indenture, being: (i) in the United States, Title 11 of the United States Code or any similar Federal or State law for the relief of debtors; or (ii) in Canada, the *Winding-Up and Restructuring Act* (Canada), the arrangement provisions of any corporate statute invoked by a corporation to propose a compromise or an arrangement with respect to claims of creditors or any class of creditors of the corporation (or any partnership for which a corporation is a general partner) or any other like, equivalent or analogous legislation of any jurisdiction, domestic or foreign. The term "Custodian" means any receiver, trustee, assignee, liquidator or a similar official under any Insolvency Law.

"Default" means any event which is, or after notice or passage of time would be, an Event of Default. A Default under subparagraph (3) above is not an Event of Default until the trustee or the holders of at least 25% in principal amount of the series notify us of the Default and we do not cure the Default within the time specified after receipt of the notice.

The trustee may require indemnity satisfactory to it before it enforces the indentures or the debt securities of the series. Subject to certain limitations, holders of a majority in principal amount of the debt securities of the series may direct the trustee in its exercise of any trust or power with respect to such series. Except in the case of Default in payment on a series, the trustee may withhold from securityholders of such series notice of any continuing Default if the trustee determines that withholding notice is in the interest of such Securityholders. We are required to furnish the trustee annually a brief certificate as to our compliance with all conditions and covenants under the indentures.

The indentures do not have cross-default provisions. Thus, a default by us on any other debt, including any other series of debt securities, would not constitute an Event of Default.

**Amendments and Waivers**

The indentures and the debt securities or any coupons of the series may be amended, and any Default may be waived as follows:

Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), the debt securities and the indentures may be amended with the consent of the holders of a majority in principal amount of the debt securities of all series affected voting as one class. Unless the securities resolution or supplemental indenture otherwise provides (in which event the applicable prospectus supplement will so state), a Default other than a Default in payment on a particular series may be waived with the consent of the holders of a majority in principal amount of the debt securities of the series. However, without the consent of each securityholder affected, no amendment or waiver may:

&nbsp;&nbsp;&nbsp;&nbsp;· change the
 fixed maturity of or the time for payment of interest on any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;· reduce the
 principal, premium or interest payable with respect to any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;· change the
 place of payment of a debt security or the currency in which the principal or interest on
 a debt security is payable;

&nbsp;&nbsp;&nbsp;&nbsp;· change the
 provisions for calculating any redemption or repurchase price with respect to any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;· reduce the
 amount of debt securities whose holders must consent to an amendment or waiver;

&nbsp;&nbsp;&nbsp;&nbsp;· make any change
 that materially adversely affects the right to convert any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;· waive any Default
 in payment of principal of or interest on a debt security; or

&nbsp;&nbsp;&nbsp;&nbsp;· adversely affect
 any holder's rights with respect to redemption or repurchase of a debt security.

Without the consent of any securityholder, the indentures or the debt securities may be amended to:

&nbsp;&nbsp;&nbsp;&nbsp;· provide
 for assumption of our obligations to securityholders in the event of a merger, amalgamation
 or consolidation requiring such assumption;

· to
 cure any ambiguity, omission, defect or inconsistency;

· to
 conform the terms of the debt securities to the description thereof in the prospectus and
 prospectus supplement offering such debt securities;

· to
 create a series and establish its terms;

· to
 provide for assumption of our obligations to securityholders in the event of a merger, amalgamation
 or consolidation requiring such assumption;

· to
 make any change that does not adversely affect the rights of any securityholder;

· to
 add to our covenants; or

· to
 make any other change to the indentures so long as no debt securities are outstanding.

**Conversion Rights**

Any securities resolution or supplemental indenture establishing a series of debt securities may provide that the debt securities of such series will be convertible at the option of the holders thereof into or for our common shares or other equity or debt instruments. The securities resolution or supplemental indenture may establish, among other things, (1) the number or amount of common shares or other equity or debt instruments for which $1,000 aggregate principal amount of the debt securities of the series is convertible, as may be adjusted pursuant to the terms of the relevant indenture and the securities resolution; and (2) provisions for adjustments to the conversion rate and limitations upon exercise of the conversion right. The indentures provide that we will not be required to make an adjustment in the conversion rate unless the adjustment would require a cumulative change of at least 1% in the conversion rate. However, we will carry forward any adjustments that are less than 1% of the conversion rate and take them into account in any subsequent adjustment of the conversion rate.

**Legal Defeasance and Covenant Defeasance**

Debt securities of a series may be defeased in accordance with their terms and, unless the securities resolution or supplemental indenture establishing the terms of the series otherwise provides, as set forth below. We at any time may terminate as to a series all of our obligations (except for certain obligations, including obligations with respect to the defeasance trust and obligations to register the transfer or exchange of a debt security, to replace destroyed, lost or stolen debt securities and coupons and to maintain paying agencies in respect of the debt securities) with respect to the debt securities of the series and any related coupons and the relevant indenture, which we refer to as legal defeasance. We at any time may terminate as to a series our obligations with respect to any restrictive covenants which may be applicable to a particular series, which we refer to as covenant defeasance.

We may exercise our legal defeasance option notwithstanding our prior exercise of our covenant defeasance option. If we exercise our legal defeasance option, a series may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option, a series may not be accelerated by reference to any covenant which may be applicable to a series.

To exercise either defeasance option as to a series, we must (1) irrevocably deposit in trust with the trustee (or another trustee) money or U.S. Government Obligations (as defined below), deliver a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due on the deposited U.S. Government Obligations, without reinvestment, plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal and interest when due on all debt securities of such series to maturity or redemption, as the case may be; and (2) comply with certain other conditions. In particular, we must obtain an opinion of tax counsel that the defeasance will not result in recognition of any gain or loss to holders for United States or Canadian federal income tax purposes.

"U.S. Government Obligations" means direct obligations of the United States or any agency or instrumentality of the United States, the payment of which is unconditionally guaranteed by the United States, which, in either case, have the full faith and credit of the United States pledged for payment and which are not callable at the issuer's option, or certificates representing an ownership interest in such obligations.

**Regarding the Trustee**

Unless otherwise indicated in a prospectus supplement, the trustee will also act as depository of funds, transfer agent, paying agent and conversion agent, as applicable, with respect to the debt securities. We may remove the trustee as the trustee under a given indenture with or without cause if we so notify the trustee three months in advance and if no Default occurs during the three-month period. The indenture trustee may also provide additional unrelated services to us as a depository of funds, registrar, trustee and similar services.

**Governing Law**

The indentures and the debt securities will be governed by New York law, except to the extent that the Trust Indenture Act of 1939 is applicable.

**DESCRIPTION OF SUBSCRIPTION RIGHTS**

We may issue subscription rights to purchase our equity or debt securities. These subscription rights may be offered independently or together with any other security offered hereby and may or may not be transferable by the shareholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we offer, if any, will, to the extent applicable, include specific terms relating to the offering, including some or all of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 price, if any, for the subscription rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 exercise price payable for our equity or debt securities upon the exercise of the subscription
 rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 number of subscription rights to be issued to each shareholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 number and terms of our equity or debt securities which may be purchased per each subscription
 right;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 extent to which the subscription rights are transferable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any
 other terms of the subscription rights, including the terms, procedures and limitations relating
 to the exchange and exercise of the subscription rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 date on which the right to exercise the subscription rights shall commence, and the date
 on which the subscription rights shall expire;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 extent to which the subscription rights may include an over-subscription privilege with respect
 to unsubscribed securities or an over-allotment privilege to the extent the securities are
 fully subscribed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if
 applicable, the material terms of any standby underwriting or purchase arrangement which
 may be entered into by us in connection with the offering of subscription rights.

**DESCRIPTION OF UNITS**

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security (but, to the extent convertible securities are included in the units, the holder of the units will be deemed the holder of the convertible securities and not the holder of the underlying securities). The unit agreement under which a unit is issued, if any, may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date. The applicable prospectus supplement may describe:

&nbsp;&nbsp;&nbsp;&nbsp;· the designation
 and terms of the units and of the securities comprising the units, including whether and
 under what circumstances those securities may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;· any provisions
 for the issuance, payment, settlement, transfer or exchange of the units or of the securities
 comprising the units;

&nbsp;&nbsp;&nbsp;&nbsp;· the terms of
 the unit agreement governing the units;

&nbsp;&nbsp;&nbsp;&nbsp;· material Canadian
 or United States federal income tax considerations applicable to the units; and

&nbsp;&nbsp;&nbsp;&nbsp;· whether the
 units will be issued in fully registered global form.

This summary of certain general terms of units and any summary description of units in the applicable prospectus supplement do not purport to be complete and are qualified in their entirety by reference to all provisions of the applicable unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units. The forms of the unit agreements and other documents relating to a particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you.

**FORMS OF SECURITIES**

Each debt security and, to the extent applicable, warrant, subscription right and unit, will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each investor's beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

**Global Securities**

*Registered Global Securities*. We may issue the registered debt securities and, to the extent applicable, warrants, subscription rights and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities and any payments to holders with respect to warrants represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of the Company, the trustees, the warrant agents or any other agent of the Company, agent of the trustees or agent of the warrant will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or warrant agent or other relevant agent of ours or theirs. It is expected that the depositary's instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

**PLAN OF DISTRIBUTION**

**Initial Offering and Sale of Securities**

Unless otherwise set forth in a prospectus supplement accompanying this prospectus, we may sell the securities being offered hereby, from time to time, by one or more of the following methods:

&nbsp;&nbsp;&nbsp;&nbsp;· to or through
 underwriting syndicates represented by managing underwriters;

&nbsp;&nbsp;&nbsp;&nbsp;· through one
 or more underwriters without a syndicate for them to offer and sell to the public;

&nbsp;&nbsp;&nbsp;&nbsp;· through dealers
 or agents; and

&nbsp;&nbsp;&nbsp;&nbsp;· to investors
 directly in negotiated sales or in competitively bid transactions.

Offerings of securities covered by this prospectus also may be made into an existing trading market for those securities in transactions at other than a fixed price, either:

&nbsp;&nbsp;&nbsp;&nbsp;· on or through
 the facilities of the Nasdaq Capital Market or any other securities exchange or quotation
 or trading service on which those securities may be listed, quoted, or traded at the time
 of sale; and/or

&nbsp;&nbsp;&nbsp;&nbsp;· to or through
 a market maker other than on the securities exchanges or quotation or trading services set
 forth above.

Those at-the-market offerings, if any, will be conducted by underwriters acting as principal or agent of the Company, who may also be third-party sellers of securities as described above. The prospectus supplement with respect to the offered securities will set forth the terms of the offering of the offered securities, including:

&nbsp;&nbsp;&nbsp;&nbsp;· the name or
 names of any underwriters, dealers or agent;

&nbsp;&nbsp;&nbsp;&nbsp;· the purchase
 price of the offered securities and the proceeds to us from such sale;

&nbsp;&nbsp;&nbsp;&nbsp;· any underwriting
 discounts and commissions or agency fees and other items constituting underwriters'
 or agents' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;· any initial
 public offering price and any discounts or concessions allowed or reallowed or paid to dealers;

&nbsp;&nbsp;&nbsp;&nbsp;· any securities
 exchange on which such offered securities may be listed; and

&nbsp;&nbsp;&nbsp;&nbsp;· any underwriter,
 agent or dealer involved in the offer and sale of any series of the securities.

The distribution of the securities may be effected from time to time in one or more transactions:

&nbsp;&nbsp;&nbsp;&nbsp;· at fixed prices,
 which may be changed;

&nbsp;&nbsp;&nbsp;&nbsp;· at market prices
 prevailing at the time of the sales;

&nbsp;&nbsp;&nbsp;&nbsp;· at varying
 prices determined at the time of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;· at negotiated
 prices.

Each prospectus supplement will set forth the manner and terms of an offering of securities including:

&nbsp;&nbsp;&nbsp;&nbsp;· whether that
 offering is being made to underwriters, through agents or directly to the public;

&nbsp;&nbsp;&nbsp;&nbsp;· the rules and
 procedures for any auction or bidding process, if used;

&nbsp;&nbsp;&nbsp;&nbsp;· the securities'
 purchase price or initial public offering price; and

&nbsp;&nbsp;&nbsp;&nbsp;· the proceeds
 we anticipate from the sale of the securities, if any.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The applicable prospectus supplement may indicate, in connection with such a transaction, that the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities pledged by us or borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

**Sales Through Underwriters**

If underwriters are used in the sale of some or all of the securities covered by this prospectus, the underwriters will acquire the securities for their own account. The underwriters may resell the securities, either directly to the public or to securities dealers, at various times in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to certain conditions. Unless indicated otherwise in a prospectus supplement, the underwriters will be obligated to purchase all the securities of the series offered if any of the securities are purchased.

Any public offering price and any concessions allowed or reallowed to dealers may be changed intermittently.

**Sales Through Agents**

Unless otherwise indicated in the applicable prospectus supplement, when securities are sold through an agent, the designated agent will agree, for the period of its appointment as agent, to use specified efforts to sell the securities for our account and will receive commissions from us as will be set forth in the applicable prospectus supplement.

Securities bought in accordance with a redemption or repayment under their terms also may be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing by one or more firms acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the prospectus supplement. Remarketing firms may be deemed to be underwriters in connection with the securities remarketed by them.

If so indicated in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers by certain specified institutions to purchase securities at a price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a future date specified in the prospectus supplement. These contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of these contracts.

**Direct Sales**

We may also sell offered securities directly to institutional investors or others. In this case, no underwriters or agents would be involved. The terms of such sales will be described in the applicable prospectus supplement.

**General Information**

Broker-dealers, agents or underwriters may receive compensation in the form of discounts, concessions or commissions from us and/or the purchasers of securities for whom such broker-dealers, agents or underwriters may act as agents or to whom they sell as principal, or both. This compensation to a particular broker-dealer might be in excess of customary commissions.

Underwriters, dealers and agents that participate in any distribution of the offered securities may be deemed "underwriters" within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), so any discounts or commissions they receive in connection with the distribution may be deemed to be underwriting compensation. Those underwriters and agents may be entitled, under their agreements with us, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution by us to payments that they may be required to make in respect of those civil liabilities. Certain of those underwriters or agents may be customers of, engage in transactions with, or perform services for, us or our affiliates in the ordinary course of business. We will identify any underwriters or agents, and describe their compensation, in a prospectus supplement. Any institutional investors or others that purchase offered securities directly, and then resell the securities, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act.

We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, if we enter into any material arrangement with a broker, dealer, agent or underwriter for the sale of securities through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. Such prospectus supplement will disclose:

&nbsp;&nbsp;&nbsp;&nbsp;· the name of
 any participating broker, dealer, agent or underwriter;

&nbsp;&nbsp;&nbsp;&nbsp;· the number
 and type of securities involved;

&nbsp;&nbsp;&nbsp;&nbsp;· the price at
 which such securities were sold;

&nbsp;&nbsp;&nbsp;&nbsp;· any securities
 exchanges on which such securities may be listed;

&nbsp;&nbsp;&nbsp;&nbsp;· the commissions
 paid or discounts or concessions allowed to any such broker, dealer, agent or underwriter,
 where applicable; and

&nbsp;&nbsp;&nbsp;&nbsp;· other facts
 material to the transaction.

In order to facilitate the offering of certain securities under this prospectus or an applicable prospectus supplement, certain persons participating in the offering of those securities may engage in transactions that stabilize, maintain or otherwise affect the price of those securities during and after the offering of those securities. Specifically, if the applicable prospectus supplement permits, the underwriters of those securities may over-allot or otherwise create a short position in those securities for their own account by selling more of those securities than have been sold to them by us and may elect to cover any such short position by purchasing those securities in the open market.

In addition, the underwriters may stabilize or maintain the price of those securities by bidding for or purchasing those securities in the open market and may impose penalty bids, under which selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The imposition of a penalty bid may also affect the price of securities to the extent that it discourages resales of the securities. No representation is made as to the magnitude or effect of any such stabilization or other transactions. Such transactions, if commenced, may be discontinued at any time.

In order to comply with the securities laws of certain states, if applicable, the securities must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Rule 15c6-1 under the Exchange Act generally requires that trades in the secondary market settle in two business days, unless the parties to any such trade expressly agree otherwise. Your prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the second business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than two scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

This prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format may be made available on the Internet sites of, or through other online services maintained by, us and/or one or more of the agents and/or dealers participating in an offering of securities, or by their affiliates. In those cases, prospective investors may be able to view offering terms online and, depending upon the particular agent or dealer, prospective investors may be allowed to place orders online.

Other than this prospectus, any applicable prospectus supplement and any applicable pricing supplement in electronic format, the information on our website or the website of any agent or dealer, and any information contained in any other website maintained by any agent or dealer:

&nbsp;&nbsp;&nbsp;&nbsp;· is not part
 of this prospectus, any applicable prospectus supplement or any applicable pricing supplement
 or the registration statement of which they form a part;

&nbsp;&nbsp;&nbsp;&nbsp;· has not been
 approved or endorsed by us or by any agent or dealer in its capacity as an agent or dealer,
 except, in each case, with respect to the respective website maintained by such entity; and

&nbsp;&nbsp;&nbsp;&nbsp;· should not
 be relied upon by investors.

There can be no assurance that we will sell all or any of the securities offered by this prospectus.

This prospectus may also be used in connection with any issuance of common shares or preferred shares upon exercise of a warrant if such issuance is not exempt from the registration requirements of the Securities Act.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

The securities offered under this prospectus may be distributed pursuant to a prospectus exemption under applicable Canadian securities laws on the basis that the securities are being distributed outside Canada. The prospectus supplement may provide additional disclosure with respect to Canadian securities matters, including agreements or representations required from underwriters or purchasers to ensure compliance with Canadian securities laws.

**CERTAIN U.S. AND CANADIAN FEDERAL INCOME TAX CONSIDERATIONS**

Information regarding material Canadian and U.S. federal income tax consequences to persons investing in the securities offered by this prospectus will be set forth in an applicable prospectus supplement. You are urged to consult your own tax advisors prior to any acquisition of our securities.

**LEGAL MATTERS**

In connection with particular offerings of the securities in the future, unless otherwise stated in the applicable prospectus supplement, the validity of the securities being offered hereby will be passed upon for us by Fasken Martineau DuMoulin, LLP, Toronto, Ontario, Canada and certain other matters will be passed upon for us by Lowenstein Sandler LLP, New York, New York. Any underwriters will also be advised about legal matters by their own counsel, which will be named in the prospectus supplement.

**EXPERTS**

The consolidated financial statements incorporated into this prospectus by reference to our Annual Report on Form 10-K for the financial years ended September 30, 2021 and 2020, have been so incorporated in reliance on the report of MNP LLP, independent auditors, given on the authority of said firm as experts in auditing and accounting.
