Accounting Policies [Abstract] |
Use of Estimates, Policy [Policy Text Block] | Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period or year. Actual results could differ from those estimates. Areas where significant judgment is involved in making estimates are valuation of accounts and other receivable; valuation and useful lives of property and equipment; intangible assets; right-of-use assets; deferred income taxes; the determination of fair value of share-based compensation; the determination of fair value of warrants in order to allocate proceeds from equity issuances; and forecasting future cash flows for assessing the going concern assumption.
Functional and Reporting Currencies [Policy Text Block] | Functional and reporting currencies The consolidated financial statements of the Company are presented in U.S. dollars, unless otherwise stated, which is the Company’s and its wholly owned subsidiary’s, Edesa Biotech USA, Inc., functional currency. The functional currency of the Company’s wholly owned subsidiary, Edesa Biotech Research, Inc., as determined by management, is Canadian dollars.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and cash equivalents Cash and cash equivalents consist of demand deposits with financial institutions held in checking, savings and money market mutual funds and highly liquid investments which are readily convertible into cash with maturities of three months or less when purchased. The carrying amount of cash and cash equivalents approximates its fair value due to its short-term nature.
Accounts Receivable [Policy Text Block] | Accounts and other receivables The Company assesses the collectability of its accounts receivables through a review of its current aging and payment terms, as well as an analysis of its historical collection rate, general economic conditions and credit status of the government agencies. Accounts and other receivables include reimbursement grant income for the Company’s federal grant with the Canadian government’s SIF and Harmonized Sales Tax (HST) refunds receivables. As of September 30, 2024, all outstanding accounts, grants and HST refunds receivables were deemed to be fully collectible, and therefore, no allowance for doubtful accounts was recorded.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and equipment Property and equipment are recorded at historical cost less accumulated depreciation and any accumulated impairment losses. Depreciation is recorded to write off the cost of assets less their residual values over their useful lives, using the declining balance and straight-line methods. Maintenance and repair expenditures that do not improve or extend the life are expensed in the period incurred. Any gain or loss arising on the disposal or retirement of an item of property and equipment is recognized as the difference between the sales proceeds and the carrying amount of the asset. The estimated useful lives, residual values and depreciation methods are reviewed at the end of each year, with the effect of any changes in estimate accounted for on a prospective basis. The Company capitalizes expenditures greater than $5,000. The Company changed its depreciation policy to straight line depreciation. The depreciation policy for the principal asset categories are calculated as follows:
| ● | Computer equipment 30% declining balance method or straight line 3 years
| ● | Furniture and equipment 20% declining balance method or straight line for 4 years
Goodwill and Intangible Assets, Policy [Policy Text Block] | Intangible assets Intangible assets represent the exclusive world-wide rights to know-how, patents and data relating to certain monoclonal antibodies (the Constructs), including sublicensing rights, acquired by entering into a license agreement with a pharmaceutical development company. Unless earlier terminated, the term of the license agreement will remain in effect for 25 years from the date of first commercial sale of licensed products containing the Constructs. Subsequently, the license agreement will automatically renew for five-year periods unless either party terminates the agreement in accordance with its terms. Intangible assets are stated at their historical cost, amortized on a straight-line basis over their expected useful lives, which is 25 years, and subject to impairment review at the end of each year.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of long-lived assets Long-lived assets are tested for impairment when indicators of impairment exist. When a significant change in the expected timing or amount of the future cash flows of the financial asset is identified, the carrying amount of the financial asset is reduced and the amount of the write-down is recognized as a loss.
Lessee, Leases [Policy Text Block] | Right-of-Use assets and liabilities The Company recognizes right-of-use (ROU) assets and liabilities on the balance sheet for operating leases with terms longer than 12 months. The Company follows the ongoing practical expedient not to recognize ROU assets and liabilities for short-term leases. The ROU assets are initially measured at cost and amortized using the straight-line method through the end of the lease term. The ROU liabilities are initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the Company's incremental borrowing rate.
Fair Value Measurement, Policy [Policy Text Block] | Fair value measurement The Company uses the fair value measurement framework for valuing financial assets and liabilities. See Note 11.
Revenue [Policy Text Block] | Reimbursement Grant Income Reimbursement grant income is recognized based on the reimbursement rate included in the government contribution agreement when allowable expenses have been incurred.
Research and Development Expense, Policy [Policy Text Block] | Research and development Research and development expenses principally consist of (i) contract research organizations for clinical trial management services, (ii) contract manufacturing organizations for manufacturing the drug compound(s) for use in clinical trials and (iii) salaries of employees directly involved in research and development efforts. Research and development costs are expensed as incurred.
Share-Based Payment Arrangement [Policy Text Block] | Share-based compensation The Company has equity incentive plans under which various types of equity-based awards including share options, restricted shares and restricted share unit awards may be granted to employees, non-employee directors and non-employee consultants and warrants that may be granted as compensation to non-employees. The Company measures the cost of equity-settled transactions by reference to the fair value of the equity instruments at the date at which they are granted. The Company recognizes compensation expense for all share-based awards based on the estimated grant-date fair values. For restricted share unit awards to employees, the fair value is based on the 5-day volume weighted average price (VWAP) of the Company’s common shares up to the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service period. The fair value of share options is determined using the Black-Scholes option pricing model. The Company utilizes a dividend yield of zero based on the fact that the Company has never paid cash dividends and has no current intention of paying cash dividends. The Company elected an accounting policy to record forfeitures as they occur. See Note 8 for a discussion of the assumptions used by the Company in determining the grant date fair value of options granted under the Black-Scholes option pricing model, as well as a summary of the share option activity under the Company’s share-based compensation plan for all years presented. The provisions of the Company’s share-based compensation plans do not require the Company to settle any options or restricted share units by transferring cash or other assets, and therefore the Company classifies the awards as equity.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Translation of foreign currency transactions The Company’s reporting currency is the U.S. dollar. The financial statements of the wholly owned Canadian subsidiary is measured using the Canadian dollar as the functional currency. Assets and liabilities of the Canadian operation have been translated at year-end exchange rates and related revenue and expenses have been translated at average exchange rates for the year. Accumulated gains and losses resulting from the translation of the financial statements of the Canadian operation are included as part of accumulated other comprehensive loss, a separate component of shareholders’ equity. For other transactions denominated in currencies other than the Company’s functional currency, the monetary assets and liabilities are translated at the year-end rates. Revenue and expenses are translated at rates of exchange prevailing on the transaction dates. Non-monetary balance sheet and related income statement accounts are remeasured into U.S. dollar using historical exchange rates. All of the exchange gains or losses resulting from these other transactions are recognized in the statements of operations and comprehensive loss.
Income Tax, Policy [Policy Text Block] | Income taxes Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the tax bases of assets and liabilities and their financial statement reported amounts using enacted tax rates and laws in effect in the year in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets when it is determined to be more likely than not that the deferred tax asset will not be realized. The Company assesses the likelihood of the financial statement effect of a tax position that should be recognized when it is more likely than not that the position will be sustained upon examination by a taxing authority based on the technical merits of the tax position, circumstances, and information available as of the reporting date. The Company is subject to examination by taxing authorities in Canada and the U.S. Management does not believe that there are any uncertain tax positions that would result in an asset or liability for taxes being recognized in the accompanying financial statements. The Company recognizes tax-related interest and penalties, if any, as a component of income tax expense. The Company accounts for income taxes on a tax jurisdictional basis. The Company files income tax returns in Canada, the provinces of British Columbia and Ontario, the U.S. and the state of California.
Earnings Per Share, Policy [Policy Text Block] | Earnings (loss) per share Basic earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding during the year. The computation of diluted earnings (loss) per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on earnings (loss) per share. The dilutive effect of convertible securities would be reflected in diluted earnings per share by application of the “if converted” method. The dilutive effect of outstanding share options and warrants and their equivalents would be reflected in diluted earnings per share by application of the treasury stock method. However, conversion of outstanding share options and warrants would have an antidilutive effect on loss per share for the years ended September 30, 2024 and 2023 and are therefore excluded from the computation of diluted loss per share. See Note 8 for share options and warrants at September 30, 2024 and 2023.
Segment Reporting, Policy [Policy Text Block] | Segmented information The Company’s operations comprise a single reportable segment engaged in the research and development, manufacturing and commercialization of innovative pharmaceutical products. As the operations comprise a single reportable segment, amounts disclosed in the consolidated financial statements for net loss, comprehensive loss, depreciation and total assets also represent segmented amounts.
New Accounting Pronouncements, Policy [Policy Text Block] | Adoption of recent accounting pronouncements On October 1, 2022, the Company adopted Accounting Standards Update ASU 2021-10 Disclosure by Business Entities About Government Assistance, modifying ASC Topic 832, Government Assistance. The amendments in ASU 2021-10 require disclosure of information about certain types of government assistance received. The Company expanded its disclosures related to government assistance. Future accounting pronouncements In November 2023, the FASB issued Accounting Standards Update ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an interim and annual basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal periods beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on the consolidated financial statements and disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. This guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to provide enhancements to annual income tax disclosures. The standard will require more detailed information in the rate reconciliation table and for income taxes paid, among other enhancements. The standard is effective for years beginning after December 15, 2024 and early adoption is permitted. The Company is currently evaluating the impact of the guidance on the consolidated financial statements and disclosures.
