Going Concern, Nature of Operations, and Corporate History [Abstract]
Going concern, nature of operations, and corporate history	1 Going concern, nature of operations, and corporate history Going concern These consolidated financial statements have been prepared on a going concern basis which assumes that DelMar Pharmaceuticals, Inc. (the “Company”) will continue its operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business. For the year ended June 30, 2018, the Company reported a loss of $11,138,312, and a negative cash flow from operations of $9,850,850. The Company had an accumulated deficit of $52,441,337 as of June 30, 2018. As of June 30, 2018, the Company has cash and cash equivalents on hand of $5,971,995. The Company is in the development stage and has not generated any revenues to date. The Company does not have the prospect of achieving revenues until such time that its product candidate is commercialized, or partnered, which may not ever occur. In the near future, the Company will require additional funding to maintain its clinical trials, research and development projects, and for general operations. These circumstances indicate substantial doubt exists about the Company’s ability to continue as a going concern. Consequently, management is pursuing various financing alternatives to fund the Company’s operations so it can continue as a going concern. Management plans to secure the necessary financing through the issue of new equity and/or the entering into of strategic partnership arrangements. The Company may tailor its drug candidate development program based on the amount of funding the Company is able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful. These financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern. Such adjustments could be material. Nature of operations The Company is a clinical-stage drug development company with a focus on the treatment of cancer that is conducting clinical trials in the United States with its product candidate, VAL-083, as a potential new treatment for glioblastoma multiforme, the most common and aggressive form of brain cancer. The Company has also acquired certain commercial rights to VAL-083 in China where it is approved as a chemotherapy for the treatment of chronic myelogenous leukemia and lung cancer. In order to accelerate the Company’s development timelines, the Company leverages existing clinical and commercial data from a wide range of sources. The Company may seek marketing partnerships in order to generate future royalty revenue. The address of the Company’s administrative offices is Suite 720 - 999 West Broadway, Vancouver, British Columbia, V5Z 1K5 with clinical operations located at 3485 Edison Way, Suite R, Menlo Park, California, 94025. Corporate history The Company is a Nevada corporation formed on June 24, 2009 under the name Berry Only Inc. On January 25, 2013 (the “Reverse Acquisition Closing Date”), the Company entered into and closed an exchange agreement (the “Exchange Agreement”), with Del Mar Pharmaceuticals (BC) Ltd. (“Del Mar (BC)”), 0959454 B.C. Ltd. (“Callco”), and 0959456 B.C. Ltd. (“Exchangeco”) and the security holders of Del Mar (BC). Upon completion of the Exchange Agreement, Del Mar (BC) became a wholly-owned subsidiary of the Company (the “Reverse Acquisition”). DelMar Pharmaceuticals, Inc. is the parent company of Del Mar (BC), a British Columbia, Canada corporation incorporated on April 6, 2010, which is a clinical stage company with a focus on the development of drugs for the treatment of cancer. The Company is also the parent company to Callco and Exchangeco which are British Columbia, Canada corporations. Callco and Exchangeco were formed to facilitate the Reverse Acquisition. References to the Company refer to the Company and its wholly-owned subsidiaries, Del Mar (BC), Callco and Exchangeco.

Significant Accounting Policies [Abstract]
Significant accounting policies	2 Significant accounting policies Reverse Stock Split On May 16, 2016, the Company filed a Certificate of Change with the Secretary of State of Nevada that effected a 1-for-4 (1:4) reverse stock split of its common stock, par value $0.001 per share. The reverse split became effective on May 20, 2016. Pursuant to the Certificate of Change, the Company’s authorized common stock was decreased in the same proportion as the split resulting in a decrease from 200,000,000 authorized shares of common stock to 50,000,000 shares authorized. The par value of its common stock was unchanged at $0.001 per share, post-split. All common shares, warrants, stock options, conversion ratios, and per share information in these consolidated financial statements give retroactive effect to the 1-for-4 reverse stock split. The Company’s authorized and issued preferred stock was not affected by the split. Basis of presentation The consolidated financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”) and are presented in United States dollars. The Company’s functional currency is the United States dollar. The principal accounting policies applied in the preparation of these consolidated financial statements are set out below and have been consistently applied to all years presented. Consolidation The consolidated financial statements of the Company include the accounts of Del Mar (BC), Callco, and Exchangeco as at and for the years ended June 30, 2018 and 2017. Intercompany balances and transactions have been eliminated in consolidation. Use of estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, expenses, contingent assets and contingent liabilities as at the end of, or during, the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring management to make estimates include the derivative liability, the valuation of equity instruments issued for services, and clinical trial accruals. Further details of the nature of these assumptions and conditions may be found in the relevant notes to these consolidated financial statements. Cash and cash equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities from the purchase date of three months or less that can be readily convertible into known amounts of cash. Cash and cash equivalents are held at recognized Canadian and United States financial institutions. Interest earned is recognized in the consolidated statement of operations and comprehensive loss. Foreign currency translation The functional currency of the Company at June 30, 2018 and 2017 is the United States dollar. Transactions that are denominated in a foreign currency are remeasured into the functional currency at the current exchange rate on the date of the transaction. Any foreign-currency denominated monetary assets and liabilities are subsequently remeasured at current exchange rates, with gains or losses recognized as foreign exchange losses or gains in the consolidated statement of operations and comprehensive loss. Non-monetary assets and liabilities are translated at historical exchange rates. Expenses are translated at average exchange rates during the period. Exchange gains and losses are included in consolidated statement of operations and comprehensive loss for the period. Current and deferred income taxes The Company follows the liability method of accounting for income taxes. Under this method, current income taxes are recognized for the estimated income taxes payable for the current period. Income taxes are accounted for using the asset and liability method of accounting. Deferred income taxes are recognized for the future income tax consequences attributable to differences between the carrying values of assets and liabilities and their respective income tax bases and for loss carry-forwards. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the periods in which temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax laws, or rates, is included in earnings in the period that includes the enactment date. When realization of deferred income tax assets does not meet the more-likely-than-not criterion for recognition, a valuation allowance is provided. Financial instruments The Company has financial instruments that are measured at fair value. To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability. The three levels of inputs that may be used to measure fair value are as follows: ● Level one - inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities; ● Level two - inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals; and ● Level three - unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s financial instruments consist of cash and cash equivalents, taxes and other receivables, accounts payable and accrued liabilities, related party payables and derivative liability. The carrying values of cash and cash equivalents, taxes and other receivables, accounts payable and accrued liabilities, and related party payables approximate their fair values due to the immediate, or short-term, maturity of these financial instruments. Derivative liability The Company accounts for certain warrants under the authoritative guidance on accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own stock, on the understanding that in compliance with applicable securities laws, the warrants require the issuance of securities upon exercise and do not sufficiently preclude an implied right to net cash settlement. The Company classifies these warrants on its balance sheet as a derivative liability which is fair valued at each reporting period subsequent to the initial issuance. The Company has used a binomial model as well as a Black-Scholes Option Pricing Model (based on a closed-form model that uses a fixed equation) to estimate the fair value of the share warrants. Determining the appropriate fair-value model and calculating the fair value of warrants requires considerable judgment. Any change in the estimates (specifically probabilities and volatility) used may cause the value to be higher or lower than that reported. The estimated volatility of the Company’s common stock at the date of issuance, and at each subsequent reporting period, is based on the historical volatility of the Company. The risk-free interest rate is based on rates published by the government for bonds with a maturity similar to the expected remaining life of the warrants at the valuation date. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. a) Fair value of derivative liability The derivative is not traded in an active market and the fair value is determined using valuation techniques. The Company uses judgment to select a variety of methods to make assumptions that are based on specific management plans and market conditions at the end of each reporting period. The Company uses a fair value estimate to determine the fair value of the derivative liability. The carrying value of the derivative liability would be higher, or lower, as management estimates around specific probabilities change. The estimates may be significantly different from those amounts ultimately recorded in the consolidated financial statements because of the use of judgment and the inherent uncertainty in estimating the fair value of these instruments that are not quoted in an active market. All changes in the fair value are recorded in the consolidated statement of operations and comprehensive loss each reporting period. This is considered to be a Level 3 financial instrument as volatility is considered a Level 3 input. The Company has the following liabilities under the fair value hierarchy: June 30, 2018 Liability Level 1 Level 2 Level 3 Derivative liability $ - $ - $ 1,117 June 30, 2017 Liability Level 1 Level 2 Level 3 Derivative liability $ - $ - $ 61,228 Intangible assets Website development costs Website development costs are stated at cost less accumulated amortization. The Company capitalizes website development costs associated with graphics design and development of the website application and infrastructure. Costs related to planning, content input, and website operations are expensed as incurred. The Company amortizes website development costs on a straight-line basis over three years. At June 30, 2018, the total capitalized cost was $79,910 (2017 - $67,261) and the Company has recognized $24,528 and $16,683, respectively, in amortization expense during the years ended June 30, 2018 and 2017. Patents Expenditures associated with the filing, or maintenance of patents, licensing or technology agreements are expensed as incurred. Costs previously recognized as an expense are not recognized as an asset in subsequent periods. Once the Company has achieved regulatory approval, patent costs will be deferred and amortized over the remaining life of the related patent. Research and development costs (including clinical trial expenses and accruals) Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with research and development. Research and development expenses also include third-party development and clinical trial expenses noted bel0w. Such costs related to research and development are included in research and development expense until the point that technological feasibility is reached which, for the Company’s drug candidate, is generally shortly before the drug is approved by the relevant food and drug administration. Once technological feasibility is reached, such costs will be capitalized and amortized to cost of revenue over the estimated life of the product. Clinical trial expenses are a component of research and development costs and include fees paid to contract research organizations, investigators and other service providers who conduct specific research for development activities on behalf of the Company. The amount of clinical trial expenses recognized in a period related to service agreements is based on estimates of the work performed on an accrual basis. These estimates are based on patient enrollment, services provided and goods delivered, contractual terms and experience with similar contracts. The Company monitors these factors by maintaining regular communication with the service providers. Differences between actual expenses and estimated expenses recorded are adjusted for in the period in which they become known. Prepaid expenses or accrued liabilities are adjusted if payments to service providers differ from estimates of the amount of service completed in a given period. Research and development costs are expensed in the period incurred. As at June 30, 2018 and 2017, all research and development costs have been expensed. Shares for services The Company has issued equity instruments for services provided by employees and non-employees. The equity instruments are valued at the fair value of the instrument granted. Stock options The Company accounts for these awards under Accounting Standards Codification (“ASC”) 718, “Compensation - Stock Compensation” (“ASC 718”). ASC 718 requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation over the requisite service period for awards expected to vest. Compensation expense for unvested options to non-employees is revalued at each period end and is being amortized over the vesting period of the options. The determination of grant-date fair value for stock option awards is estimated using the Black-Scholes model, which includes variables such as the expected volatility of the Company’s share price, the anticipated exercise behavior of its grantee, interest rates, and dividend yields. These variables are projected based on the Company’s historical data, experience, and other factors. Changes in any of these variables could result in material adjustments to the expense recognized for share-based payments. Such value is recognized as expense over the requisite service period, net of actual forfeitures, using the accelerated attribution method. The Company recognizes forfeitures as they occur. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results, or updated estimates, differ from current estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised. Performance stock units The Company also accounts for performance stock units (PSU’s) under ASC 718. ASC 718 requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation over the requisite service period for awards expected to vest. As vesting of the PSU’s is based on a number of factors, the determination of the grant-date fair value for PSU’s has been estimated using a Monte Carlo simulation approach which includes variables such as the expected volatility of the Company’s share price and interest rates to generate potential future outcomes. These variables are projected based on the Company’s historical data, experience, and other factors. Changes in any of these variables could result in material adjustments to the expense recognized for the PSUs. Such value is recognized as expense over the derived service period using the accelerated attribution method. The estimation of PSUs that will ultimately vest requires judgment, and to the extent actual results, or updated estimates, differ from current estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised. Comprehensive income In accordance with ASC 220, “Comprehensive Income” (“ASC 220”), all components of comprehensive income, including net loss, are reported in the financial statements in the period in which they are recognized. Comprehensive income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net loss and other comprehensive (income) loss, including foreign currency translation adjustments, are reported, net of any related tax effect, to arrive at comprehensive income. No taxes were recorded on items of other comprehensive income. Loss per share Income or loss per share is calculated based on the weighted average number of common shares outstanding. For the years ended June 30, 2018 and 2017 diluted loss per share does not differ from basic loss per share since the effect of the Company’s warrants, stock options, performance stock units, and convertible preferred shares is anti-dilutive. As at June 30, 2018, potential common shares of 16,908,104 (2017 – 7,749,756) related to outstanding warrants and stock options, 1,200,000 (2017 – 0) relating to performance stock units, and 2,202,792 (2017 – 2,202,792) relating to outstanding Series B convertible preferred shares were excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive. Segment information The Company identifies its operating segments based on business activities, management responsibility and geographical location. The Company operates within a single operating segment being the research and development of cancer indications, and operates primarily in one geographic area, being North America. The Company is conducting one clinical trial in China but the planned expenses to be incurred over the course of the study are not expected to be significant. All of the Company’s assets are located in either Canada or the United States. Recent accounting pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. Recently adopted Accounting Standards Board (“ASU”) 2016-09 — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting The amendments in this update change existing guidance related to accounting for employee share-based payments affecting the income tax consequences of awards, classification of awards as equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. The Not yet adopted ASU 2016-01 — Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The updated guidance enhances the reporting model for financial instruments and requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. The guidance is effective for annual reporting periods beginning after December 15, 2017. The ASU 2017-09 — Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting The amendments in this update provide guidance about which changes to the terms, or conditions of a stock-based payment award, require an entity to apply modification accounting in Topic 718. The amendments in ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2017-11 — I. Accounting for Certain Financial Instruments with Down Round Features, II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Non-public Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception The amendments in this update are intended to reduce the complexity associated with the accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, a down round feature would no longer cause a freestanding equity-linked financial instrument (or an embedded conversion option) to be accounted for as a derivative liability at fair value with changes in fair value recognized in current earnings. In addition, the indefinite deferral of certain provisions of Topic 480 have been re-characterized to a scope exception. The re-characterization has no accounting effect. ASU 2017-11 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.Early adoption is permitted. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2016-02 — Leases (Topic 842) The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the consolidated balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the consolidated income statement. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2018-07 — Stock Compensation (Topic 718) Improvements to Nonemployee Shares-based payment Accounting The amendments in this update are intended to the reduce cost and complexity and to improve financial reporting for share-based payments issued to nonemployees. The ASU expands the scope of Topic 718, Compensation —Stock Compensation, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. The existing guidance on nonemployee share-based payments is significantly different from current guidance for employee share-based payments. This ASU expands the scope of the employee share-based payments guidance to include share-based payments issued to nonemployees. By doing so, the FASB improves the accounting of nonemployee share-based payments issued to acquire goods and services used in its own operations. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company is currently evaluating the potential impact of the adoption of this standard.

Derivative Liability [Abstract]
Derivative liability	4 Derivative liability The Company has issued common stock purchase warrants. Based on the terms of certain of these warrants the Company determined that the warrants were a derivative liability which is recognized at fair value at the date of the transaction and remeasured at fair value each reporting period with the changes in fair value recorded in the consolidated statement of operations and comprehensive loss. 2013 Investor Warrants During the quarter ended March 31, 2013 the Company issued an aggregate of 3,281,250 units at a purchase price of $3.20 per unit, for aggregate gross proceeds of $10,500,000. Each unit consisted of one share of common stock and one five-year warrant (the “2013 Investor Warrants”) to purchase one share of common stock at an initial exercise price of $3.20. The exercise price of the 2013 Investor Warrants is subject to adjustment in the event that the Company issues common stock at a price lower than the exercise price, subject to certain exceptions. The 2013 Investor Warrants are redeemable by the Company at a price of $0.004 per 2013 Investor Warrant at any time subject to the conditions that (i) the Company’s common stock has traded for twenty (20) consecutive trading days with a closing price of at least $6.40 per share with an average trading volume of 50,000 shares per day, and (ii) the underlying shares of common stock are registered for resale. As a result of the financing completed by the Company during the three months ended September 30, 2015, the exercise price of all of the 2013 Investor Warrants was reduced from $3.20 to $3.14. As a result of the financing completed by the Company during the three months ended September 30, 2017, the exercise price of certain of the 2013 Investor Warrants was further reduced from $3.14 to $2.68. The change in exercise price did not result in a material change in the fair value of the derivative liability. All of the 2013 Investor Warrants giving rise to their respective portion of the derivative liability have expired as of June 30, 2018. 2013 Investor Warrant exercises During the year ended June 30, 2017, 60,095 of the 2013 Investor Warrants were exercised at an exercise price of $3.14 per share. Also, 5,000 of the previously amended 2013 Investor Warrants were exercised. The Company received proceeds of $204,659 from these exercises. The warrants that have been exercised were revalued at their respective exercise dates and then the reclassification to equity was recorded resulting in $238,474 of the derivative liability being reclassified to equity. There were no exercises of 2013 Investor Warrants during the year ended June 30, 2018. 2013 Investor Warrant amendments During the year ended June 30, 2017, 15,944 of the 2013 Investor Warrants were amended. As a result, the Company has reclassified $53,006 from the derivative liability to equity. The 2013 Investor Warrants were revalued to their respective amendment dates and were then reclassified to equity. There were no amendments of 2013 Investor Warrants during the year ended June 30, 2018. 2015 Agent Warrants As part of the Company’s financing completed in a prior period, the Company issued warrants to purchase 23,477 shares of common stock to certain placement agents (“2015 Agent Warrants”) and recognized them as a derivative liability of $29,594 at the time of issuance. The 2015 Agent Warrants are exercisable at a per share price equal to $3.00 until July 15, 2020. During the year ended June 30, 2017, 680 of the 2015 Agent Warrants were exercised for cash proceeds of $2,040 and 1,000 of the 2015 Agent Warrants were exercised on a cashless basis for 594 shares of common stock. The total reclassification to equity subsequent to revaluation at the respective exercise dates was $9,935. There were no exercises of the 2015 Agent Warrants during the year ended June 30, 2018. The Company’s derivative liability is summarized as follows: Years ended June 30, 2018 2017 $ $ Opening balance 61,228 693,700 Change in fair value of warrants (60,111 ) (331,057 ) Reclassification to equity upon amendment of warrants - (53,006 ) Reclassification to equity upon exercise of warrants - (248,409 ) Closing balance 1,117 61,228 Less current portion - (33,091 ) Long-term portion 1,117 28,137 The derivative liability consists of the following warrants as at June 30, 2018 and 2017: Year ended June 30, 2018 Number of warrants $ Warrants issued for services 43,750 - 2015 Agent warrants 21,768 1,117 Closing balance 65,518 1,117 Less current portion - - Long-term portion 65,518 1,117 Year ended June 30, 2017 Number of warrants $ 2013 investor warrants 105,129 33,091 Warrants issued for services 43,750 4,468 2015 Agent warrants 21,768 23,669 Closing balance 170,647 61,228 Less current portion (105,129 ) (33,091 ) Long-term portion 65,518 28,137

Current and Deferred Income Taxes [Abstract]
Current and deferred income taxes	7 Current and deferred income taxes For the years ended June 30, 2018, and 2017, the Company did not record a provision for income taxes due to a full valuation allowance against our deferred tax assets. Significant components of the Company’s future tax assets and deferred tax liabilities are shown below: June 30, June 30, Deferred tax assets: Non-capital losses carried forward 9,416,047 7,340,286 Capital losses carried forward 17,925 17,925 Financing costs 5,512 5,512 Scientific research and development 396,758 350,435 Scientific research and development - ITC 354,411 319,528 10,190,653 8,033,686 Deferred tax liabilities: Scientific research and development – ITC (61,230 ) (53,841 ) 10,129,423 7,979,845 Valuation allowance (10,129,423 ) (7,979,845 ) Net future tax assets - - The income tax benefit of these tax attributes has not been recorded in these consolidated financial statements because of the uncertainty of their recovery. The Company’s effective income tax rate differs from the statutory income tax rate of 21% (2017 – The differences arise from the following items: June 30, June 30, Tax recovery at statutory income tax rates (3,063,036 ) (2,747,800 ) Permanent differences 290,722 (15,342 ) Effect of rate differentials between jurisdictions 76,364 464,938 Impact of changes in income tax rates 138,516 - Scientific research and development – ITC (354,411 ) - Other 75,422 (62,962 ) Change in valuation allowance 2,836,423 2,361,166 - - As of June 30, 2018, the Company had combined US and Canadian net operating loss carryforwards of $34.7 million that begin expiring in 2029. In addition, the Company has non-refundable Canadian federal investment tax credits of $226,778 that expire between 2029 and 2038 and non-refundable British Columbia investment tax credits of $127,633 that expire between 2019 and 2028. The Tax Cuts and Jobs Act (“2017 Tax Act”) was enacted in December 2017. The 2017 Tax Act, among other things, reduces the U.S. federal corporate tax rate from 35% to 21%, effective January 1, 2018, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign earnings. The Company revalued our deferred tax assets as of June 30, 2018 based on a U.S. federal tax rate of 21%, which resulted in a reduction to our deferred tax assets of $138,516 fully offset by a reduction to the valuation allowance. The Company is not required to pay a one-time transition tax on earnings of our foreign subsidiary as the foreign subsidiary has an accumulated deficit.

Financial Risk Management [Abstract]
Financial risk management	10 Financial risk management Market risk Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and equity prices will affect the Company’s income or valuation of its financial instruments. The Company is exposed to financial risk related to fluctuation of foreign exchange rates. Foreign currency risk is limited to the portion of the Company’s business transactions denominated in currencies other than the United Sates dollar, primarily general and administrative expenses incurred in Canadian dollars. The Company believes that the results of operations, financial position and cash flows would be affected by a sudden change in foreign exchange rates, but would not impair or enhance its ability to pay its Canadian dollar accounts payable. The Company manages foreign exchange risk by converting its US$ to CA$ as needed. The Company maintains the majority of its cash in US$. As at June 30, 2018, Canadian dollar denominated accounts payable and accrued liabilities exposure in US$ totaled $106,132. a) Foreign exchange risk Foreign exchange risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. If foreign exchange rates were to fluctuate within +/-10% of the closing rate at year-end, the maximum exposure is $6,788. Balances in foreign currencies at June 30, 2018 and 2017 are as follows: June 30, June 30, Trade payables 79,858 164,226 Cash 41,459 39,251 Interest, taxes, and other receivables 14,618 99,397 b) Interest rate risk The Company is subject to interest rate risk on its cash and cash equivalents and believes that the results of operations, financial position and cash flows would not be significantly affected by a sudden change in market interest rates relative to the investment interest rates due to the short-term nature of the investments. As at June 30, 2018, cash and cash equivalents held in by the Company was $5,971,995. The Company’s cash balance currently earns interest at standard bank rates. If interest rates were to fluctuate within +/-10% of the closing rate at year end the impact of the Company’s interest-bearing accounts will be not be significant due to the current low market interest rates. The only financial instruments that expose the Company to interest rate risk are its cash and cash equivalents. Liquidity risk Liquidity risk is the risk that the Company will encounter difficulty in raising funds to meet cash flow requirements associated with financial instruments. The Company continues to manage its liquidity risk based on the outflows experienced for the period ended June 30, 2018 and is undertaking efforts to conserve cash resources wherever possible. The maximum exposure of the Company’s liquidity risk is $1,638,515 as at June 30, 2018. Credit risk Credit risk arises from cash and cash equivalents, deposits with banks, financial institutions, and contractors as well as outstanding receivables. The Company limits its exposure to credit risk, with respect to cash and cash equivalents, by placing them with high quality credit financial institutions. The Company’s cash equivalents consist primarily of operating funds with commercial banks. Of the amounts with financial institutions on deposit, the following table summarizes the amounts at risk should the financial institutions with which the deposits are held cease trading: The maximum exposure of the Company’s credit risk is $39,519 at June 30, 2018 relating to interest, taxes, and other receivables. The credit risk related to uninsured cash and cash equivalents balances is $5,868,825 at June 30, 2018. Cash and Insured Non-insured 5,971,995 103,170 5,868,825 Concentration of credit risk Financial instruments that subject the Company to credit risk consist primarily of cash and cash equivalents. The Company places its cash and cash equivalents in accredited financial institutions and therefore the Company’s management believes these funds are subject to minimal credit risk. The Company has no significant off-balance sheet concentrations of credit risk such as foreign currency exchange contracts, option contracts or other hedging arrangements.

Significant Accounting Policies [Abstract]
Reverse Stock Split	Reverse Stock Split On May 16, 2016, the Company filed a Certificate of Change with the Secretary of State of Nevada that effected a 1-for-4 (1:4) reverse stock split of its common stock, par value $0.001 per share. The reverse split became effective on May 20, 2016. Pursuant to the Certificate of Change, the Company’s authorized common stock was decreased in the same proportion as the split resulting in a decrease from 200,000,000 authorized shares of common stock to 50,000,000 shares authorized. The par value of its common stock was unchanged at $0.001 per share, post-split. All common shares, warrants, stock options, conversion ratios, and per share information in these consolidated financial statements give retroactive effect to the 1-for-4 reverse stock split. The Company’s authorized and issued preferred stock was not affected by the split.
Basis of presentation	Basis of presentation The consolidated financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”) and are presented in United States dollars. The Company’s functional currency is the United States dollar. The principal accounting policies applied in the preparation of these consolidated financial statements are set out below and have been consistently applied to all years presented.
Consolidation	Consolidation The consolidated financial statements of the Company include the accounts of Del Mar (BC), Callco, and Exchangeco as at and for the years ended June 30, 2018 and 2017. Intercompany balances and transactions have been eliminated in consolidation.
Use of estimates	Use of estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, expenses, contingent assets and contingent liabilities as at the end of, or during, the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring management to make estimates include the derivative liability, the valuation of equity instruments issued for services, and clinical trial accruals. Further details of the nature of these assumptions and conditions may be found in the relevant notes to these consolidated financial statements.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents consist of cash and highly liquid investments with original maturities from the purchase date of three months or less that can be readily convertible into known amounts of cash. Cash and cash equivalents are held at recognized Canadian and United States financial institutions. Interest earned is recognized in the consolidated statement of operations and comprehensive loss.
Foreign currency translation	Foreign currency translation The functional currency of the Company at June 30, 2018 and 2017 is the United States dollar. Transactions that are denominated in a foreign currency are remeasured into the functional currency at the current exchange rate on the date of the transaction. Any foreign-currency denominated monetary assets and liabilities are subsequently remeasured at current exchange rates, with gains or losses recognized as foreign exchange losses or gains in the consolidated statement of operations and comprehensive loss. Non-monetary assets and liabilities are translated at historical exchange rates. Expenses are translated at average exchange rates during the period. Exchange gains and losses are included in consolidated statement of operations and comprehensive loss for the period.
Current and deferred income taxes	Current and deferred income taxes The Company follows the liability method of accounting for income taxes. Under this method, current income taxes are recognized for the estimated income taxes payable for the current period. Income taxes are accounted for using the asset and liability method of accounting. Deferred income taxes are recognized for the future income tax consequences attributable to differences between the carrying values of assets and liabilities and their respective income tax bases and for loss carry-forwards. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the periods in which temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax laws, or rates, is included in earnings in the period that includes the enactment date. When realization of deferred income tax assets does not meet the more-likely-than-not criterion for recognition, a valuation allowance is provided.
Financial instruments	Financial instruments The Company has financial instruments that are measured at fair value. To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability. The three levels of inputs that may be used to measure fair value are as follows: ● Level one - inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities; ● Level two - inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals; and ● Level three - unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s financial instruments consist of cash and cash equivalents, taxes and other receivables, accounts payable and accrued liabilities, related party payables and derivative liability. The carrying values of cash and cash equivalents, taxes and other receivables, accounts payable and accrued liabilities, and related party payables approximate their fair values due to the immediate, or short-term, maturity of these financial instruments. Derivative liability The Company accounts for certain warrants under the authoritative guidance on accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own stock, on the understanding that in compliance with applicable securities laws, the warrants require the issuance of securities upon exercise and do not sufficiently preclude an implied right to net cash settlement. The Company classifies these warrants on its balance sheet as a derivative liability which is fair valued at each reporting period subsequent to the initial issuance. The Company has used a binomial model as well as a Black-Scholes Option Pricing Model (based on a closed-form model that uses a fixed equation) to estimate the fair value of the share warrants. Determining the appropriate fair-value model and calculating the fair value of warrants requires considerable judgment. Any change in the estimates (specifically probabilities and volatility) used may cause the value to be higher or lower than that reported. The estimated volatility of the Company’s common stock at the date of issuance, and at each subsequent reporting period, is based on the historical volatility of the Company. The risk-free interest rate is based on rates published by the government for bonds with a maturity similar to the expected remaining life of the warrants at the valuation date. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. a) Fair value of derivative liability The derivative is not traded in an active market and the fair value is determined using valuation techniques. The Company uses judgment to select a variety of methods to make assumptions that are based on specific management plans and market conditions at the end of each reporting period. The Company uses a fair value estimate to determine the fair value of the derivative liability. The carrying value of the derivative liability would be higher, or lower, as management estimates around specific probabilities change. The estimates may be significantly different from those amounts ultimately recorded in the consolidated financial statements because of the use of judgment and the inherent uncertainty in estimating the fair value of these instruments that are not quoted in an active market. All changes in the fair value are recorded in the consolidated statement of operations and comprehensive loss each reporting period. This is considered to be a Level 3 financial instrument as volatility is considered a Level 3 input. The Company has the following liabilities under the fair value hierarchy: June 30, 2018 Liability Level 1 Level 2 Level 3 Derivative liability $ - $ - $ 1,117 June 30, 2017 Liability Level 1 Level 2 Level 3 Derivative liability $ - $ - $ 61,228
Intangible assets	Intangible assets Website development costs Website development costs are stated at cost less accumulated amortization. The Company capitalizes website development costs associated with graphics design and development of the website application and infrastructure. Costs related to planning, content input, and website operations are expensed as incurred. The Company amortizes website development costs on a straight-line basis over three years. At June 30, 2018, the total capitalized cost was $79,910 (2017 - $67,261) and the Company has recognized $24,528 and $16,683, respectively, in amortization expense during the years ended June 30, 2018 and 2017. Patents Expenditures associated with the filing, or maintenance of patents, licensing or technology agreements are expensed as incurred. Costs previously recognized as an expense are not recognized as an asset in subsequent periods. Once the Company has achieved regulatory approval, patent costs will be deferred and amortized over the remaining life of the related patent.
Research and development costs (including clinical trial expenses and accruals)	Research and development costs (including clinical trial expenses and accruals) Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related expenses associated with research and development. Research and development expenses also include third-party development and clinical trial expenses noted bel0w. Such costs related to research and development are included in research and development expense until the point that technological feasibility is reached which, for the Company’s drug candidate, is generally shortly before the drug is approved by the relevant food and drug administration. Once technological feasibility is reached, such costs will be capitalized and amortized to cost of revenue over the estimated life of the product. Clinical trial expenses are a component of research and development costs and include fees paid to contract research organizations, investigators and other service providers who conduct specific research for development activities on behalf of the Company. The amount of clinical trial expenses recognized in a period related to service agreements is based on estimates of the work performed on an accrual basis. These estimates are based on patient enrollment, services provided and goods delivered, contractual terms and experience with similar contracts. The Company monitors these factors by maintaining regular communication with the service providers. Differences between actual expenses and estimated expenses recorded are adjusted for in the period in which they become known. Prepaid expenses or accrued liabilities are adjusted if payments to service providers differ from estimates of the amount of service completed in a given period. Research and development costs are expensed in the period incurred. As at June 30, 2018 and 2017, all research and development costs have been expensed.
Shares for services	Shares for services The Company has issued equity instruments for services provided by employees and non-employees. The equity instruments are valued at the fair value of the instrument granted.
Stock options	Stock options The Company accounts for these awards under Accounting Standards Codification (“ASC”) 718, “Compensation - Stock Compensation” (“ASC 718”). ASC 718 requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation over the requisite service period for awards expected to vest. Compensation expense for unvested options to non-employees is revalued at each period end and is being amortized over the vesting period of the options. The determination of grant-date fair value for stock option awards is estimated using the Black-Scholes model, which includes variables such as the expected volatility of the Company’s share price, the anticipated exercise behavior of its grantee, interest rates, and dividend yields. These variables are projected based on the Company’s historical data, experience, and other factors. Changes in any of these variables could result in material adjustments to the expense recognized for share-based payments. Such value is recognized as expense over the requisite service period, net of actual forfeitures, using the accelerated attribution method. The Company recognizes forfeitures as they occur. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results, or updated estimates, differ from current estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.
Performance stock units	Performance stock units The Company also accounts for performance stock units (PSU’s) under ASC 718. ASC 718 requires measurement of compensation cost for all stock-based awards at fair value on the date of grant and recognition of compensation over the requisite service period for awards expected to vest. As vesting of the PSU’s is based on a number of factors, the determination of the grant-date fair value for PSU’s has been estimated using a Monte Carlo simulation approach which includes variables such as the expected volatility of the Company’s share price and interest rates to generate potential future outcomes. These variables are projected based on the Company’s historical data, experience, and other factors. Changes in any of these variables could result in material adjustments to the expense recognized for the PSUs. Such value is recognized as expense over the derived service period using the accelerated attribution method. The estimation of PSUs that will ultimately vest requires judgment, and to the extent actual results, or updated estimates, differ from current estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.
Comprehensive income	Comprehensive income In accordance with ASC 220, “Comprehensive Income” (“ASC 220”), all components of comprehensive income, including net loss, are reported in the financial statements in the period in which they are recognized. Comprehensive income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net loss and other comprehensive (income) loss, including foreign currency translation adjustments, are reported, net of any related tax effect, to arrive at comprehensive income. No taxes were recorded on items of other comprehensive income.
Loss per share	Loss per share Income or loss per share is calculated based on the weighted average number of common shares outstanding. For the years ended June 30, 2018 and 2017 diluted loss per share does not differ from basic loss per share since the effect of the Company’s warrants, stock options, performance stock units, and convertible preferred shares is anti-dilutive. As at June 30, 2018, potential common shares of 16,908,104 (2017 – 7,749,756) related to outstanding warrants and stock options, 1,200,000 (2017 – 0) relating to performance stock units, and 2,202,792 (2017 – 2,202,792) relating to outstanding Series B convertible preferred shares were excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive.
Segment information	Segment information The Company identifies its operating segments based on business activities, management responsibility and geographical location. The Company operates within a single operating segment being the research and development of cancer indications, and operates primarily in one geographic area, being North America. The Company is conducting one clinical trial in China but the planned expenses to be incurred over the course of the study are not expected to be significant. All of the Company’s assets are located in either Canada or the United States.
Recent accounting pronouncements	Recent accounting pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. Recently adopted Accounting Standards Board (“ASU”) 2016-09 — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting The amendments in this update change existing guidance related to accounting for employee share-based payments affecting the income tax consequences of awards, classification of awards as equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual periods, with early adoption permitted. The Not yet adopted ASU 2016-01 — Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The updated guidance enhances the reporting model for financial instruments and requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and the separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. The guidance is effective for annual reporting periods beginning after December 15, 2017. The ASU 2017-09 — Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting The amendments in this update provide guidance about which changes to the terms, or conditions of a stock-based payment award, require an entity to apply modification accounting in Topic 718. The amendments in ASU 2017-09 are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for (1) public business entities for reporting periods for which financial statements have not yet been issued and (2) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2017-11 — I. Accounting for Certain Financial Instruments with Down Round Features, II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Non-public Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception The amendments in this update are intended to reduce the complexity associated with the accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, a down round feature would no longer cause a freestanding equity-linked financial instrument (or an embedded conversion option) to be accounted for as a derivative liability at fair value with changes in fair value recognized in current earnings. In addition, the indefinite deferral of certain provisions of Topic 480 have been re-characterized to a scope exception. The re-characterization has no accounting effect. ASU 2017-11 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019.Early adoption is permitted. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2016-02 — Leases (Topic 842) The new standard establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the consolidated balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the consolidated income statement. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the potential impact of the adoption of this standard. ASU 2018-07 — Stock Compensation (Topic 718) Improvements to Nonemployee Shares-based payment Accounting The amendments in this update are intended to the reduce cost and complexity and to improve financial reporting for share-based payments issued to nonemployees. The ASU expands the scope of Topic 718, Compensation —Stock Compensation, which currently only includes share-based payments issued to employees, to also include share-based payments issued to nonemployees for goods and services. The existing guidance on nonemployee share-based payments is significantly different from current guidance for employee share-based payments. This ASU expands the scope of the employee share-based payments guidance to include share-based payments issued to nonemployees. By doing so, the FASB improves the accounting of nonemployee share-based payments issued to acquire goods and services used in its own operations. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company is currently evaluating the potential impact of the adoption of this standard.
