Accounting Policies [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY	1. NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY: I-Minerals Inc. (the “Company”) was incorporated under the laws of British Columbia, Canada, in 1984. The Company is listed for trading on the TSX Venture Exchange under the symbol “IMA” and the OTCQX marketplace under the symbol “IMAHF”. The Company’s principal business is the development of the Helmer-Bovill industrial mineral property (“the Property”) located in Latah County, Idaho. The Helmer-Bovill property is comprised of eleven mineral leases that host potentially economic deposits of feldspar, quartz and kaolinitic clays, primarily kaolinite and halloysite. Basis of Presentation and Liquidity The accompanying consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its obligations and continue its operations for the next year . Realization values may be substantially different from carrying values as shown and these financial statements do not give effect to adjustments that would be necessary to the carrying values and classification of assets and liabilities should the Company be unable to continue as a going concern. At April 30, 2016, the Company had not yet achieved profitable operations, had an accumulated deficit of $31,357,511 since inception and expects to incur further losses in the development of its business, all of which casts substantial doubt upon the Company’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. The Company’s ability to continue as a going concern is dependent upon its ability to complete a feasibility study, to obtain the necessary financing to develop the Property and to meet its obligations and repay its liabilities arising from normal business operations when they come due. Although the Company has been successful in the past in obtaining financing, there is no assurance that it will be able to obtain adequate financing in the future or that such financing will be on terms advantageous to the Company. The Company is currently receiving funds from a company controlled by a director of the Company through promissory notes (Notes 5, 6 and 14).

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, i-Minerals USA, Inc. and CKD Ventures Ltd. All inter-company accounts and transactions have been eliminated. The Company’s fiscal year-end is April 30 th Use of Estimates The preparation of these consolidated financial statements in conformity with US 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to the useful life and recoverability of long lived assets, stock-based compensation, amortization of Promissory Notes and Second Promissory Notes financing fees, valuation of derivative liabilities, and deferred income tax asset valuation allowances. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. Cash The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents. As at April 30, 2016 and 2015, the Company had no cash equivalents. Equipment Equipment is carried at cost and is amortized over the estimated useful economic lives using the declining balance method at an annual rate of 30%. Mineral Property Acquisition Costs Mineral property acquisition costs are capitalized when incurred and will be amortized using the units-of-production method following the commencement of production. If a mineral property is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment. The Company’s property has yet to reach the production stage. Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of mineral property claims. Mineral Property Exploration Costs Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves and all permits are received, the costs incurred to develop such property are capitalized. Such costs will be amortized using the units-of-production method over the estimated useful life of the probable reserve. If mineral properties are subsequently abandoned or impaired, any capitalized costs will be charged to operations. Impairment of Long-Lived Assets Management tests long-lived assets to be held and used for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Impairment is considered to exist if the future cash flows on an undiscounted basis are less than the carrying amount of the long-lived asset. An impairment loss is measured and recorded based on the difference between book value and fair value of the asset group, as determined through the application of a present value technique using expected future cash flows to estimate fair value in the absence of a market price. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of cash flows from other asset groups. Debt Issuance Costs Debt issue costs in connection with debt financings are capitalized as an asset and amortized over the term of the debt using the effective interest method. Debt issuance costs paid to the purchaser of the debt are considered to be a reduction of the debt proceeds and a component of debt discount. Subsequently, the costs comprising this debt discount are amortized as financing fees over the term of the promissory notes using the effective interest method. During the year ended April 30, 2016, the Company amortized financing fees totaling $372,266 (2015 – $136,189). Financial Instruments and Fair Value Measures The book value of cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of those instruments. The fair value hierarchy under US GAAP is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 - observable inputs other than Level I, quoted prices for similar assets or liabilities in active prices whose inputs are observable or whose significant value drivers are observable; and Level 3 - assets and liabilities whose significant value drivers are unobservable by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s Promissory Notes and Second Promissory Notes are based on Level 2 inputs in the ASC 820 fair value hierarchy. The Company calculated the fair value of these instruments by discounting future cash flows using rates representative of current borrowing rates. At April 30, 2016, the Promissory Notes had a fair value of $5,659,462 (2015 – $5,479,007) and the Second Promissory Notes had a fair value of $5,044,374 (2015 - $1,532,123). The Company had certain Level 3 liabilities required to be recorded at fair value on a recurring basis in accordance with US GAAP as at April 30, 2016 and 2015. As at April 30, 2016, the Company’s Level 3 liabilities consisted of the warrants issued in connection with the Company’s offering of equity units in a private placement and warrants issued as financing fees as well as the grant of share purchase options to non-employees. The resulting Level 3 liabilities have no active market and are required to be measured at their fair value each reporting period based on information that is unobservable. A summary of the Company’s Level 3 liabilities for the years ended April 30, 2016 and 2015 is as follows: 2016 $ 2015 $ Warrants (Note 7) Beginning fair value 1,128,841 3,211,386 Issuance 176,493 130,890 Change in fair value (978,739) (2,213,435) Ending fair value 326,595 1,128,841 Non-employee options (Note 8(c)) Beginning fair value 116,615 68,859 Fair value of options granted 102,273 - Fair value of options on vesting 11,366 80,361 Change in fair value (41,047) (32,605) Ending fair value 189,207 116,615 Total Level 3 liabilities 515,802 1,245,456 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). There were no assets or liabilities measured at fair value on a nonrecurring basis during the years ended April 30, 2016 and 2015. Earnings (Loss) Per Share The basic loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding. Diluted loss per common share is computed similar to basic loss per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For the year ended April 30, 2016, loss per share excludes 12,027,780 (2015 – 30,384,168) potentially dilutive common shares (related to outstanding options and warrants) as their effect was anti-dilutive Foreign Currency Translation The Company’s functional and reporting currency is the US dollar. Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the balance sheet date and non-monetary items are translated at exchange rates prevailing when the assets were acquired or obligations incurred. Gains and losses arising on translation or settlement of foreign currency denominated transactions or balances are included in the determination of income. Income Taxes The Company accounts for income taxes using the asset and liability method. The asset and liability method provides that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. The Company has adopted the provisions of FASB ASC 740 "Income Taxes" regarding accounting for uncertainty in income taxes. The Company initially recognizes tax positions in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority, assuming full knowledge of the position and all relevant facts. Application requires numerous estimates based on available information. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, and its recognized tax positions and tax benefits may not accurately anticipate actual outcomes. As additional information is obtained, there may be a need to periodically adjust the recognized tax positions and tax benefits. These periodic adjustments may have a material impact on the consolidated statements of operations. When applicable, the Company classifies penalties and interest associated with uncertain tax positions as a component of income tax expense in its consolidated Statement of Income (Loss). Stock-Based Compensation The Company accounts for all stock-based payments and awards under the fair value based method. Stock-based payments to non-employees are measured at the fair value of the consideration received, or the fair value of the equity instruments issued, or liabilities incurred, whichever is more reliably measurable. The fair value of stock-based payments to non-employees is periodically re-measured until the counterparty performance is complete, and any change therein is recognized over the vesting period of the award and in the same manner as if the Company had paid cash instead of paying with or using equity based instruments. The cost of the stock-based payments to non-employees that are fully vested and non-forfeitable as at the grant date is measured and recognized at that date, unless there is a contractual term for services in which case such compensation would be amortized over the contractual term. The Company accounts for the granting of stock options to employees using the fair value method whereby all awards to employees will be recorded at fair value on the date of the grant. The fair value of all stock options is expensed over their vesting period with a corresponding increase to additional paid-in capital. Compensation costs for stock-based payments that do not include performance conditions are recognized on a straight-line basis. Compensation cost associated with a share based award having a performance condition is only recognized over the requisite service period if it is probable. Share based awards with a performance condition are accrued on an award by award basis. The Company uses the Black-Scholes option valuation model to calculate the fair value of stock options at the date of the grant. Option pricing models require the input of highly subjective assumptions, including the expected price volatility. Changes in these assumptions can materially affect the fair value estimates. Derivative Liabilities The Company evaluates its financial instruments and other contracts to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for in accordance with ASC 815. The result of this accounting treatment is that the fair value of the embedded derivative is marked-to-market at each balance sheet date and recorded as a liability and the change in fair value is recorded in the consolidated statement of loss. Upon conversion or exercise of a derivative instrument, the instrument is marked to fair value at the conversion date and then that fair value is reclassified to equity. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. Derivative instruments that become subject to reclassification are reclassified at the fair value of the instrument on the reclassification date. Derivative instrument liabilities will be classified in the balance sheet as current or non-current based on whether or not settlement of the derivative instrument is expected within 12 months of the balance sheet date. The Company uses the Black-Scholes option valuation model to value derivative liabilities. This model uses Level 3 inputs in the fair value hierarchy established by ASC 820 Fair Value Measurement. Concentration of Risk The Company is subject to interest rate risk on its debt financings. The Company generally uses fixed interest rates for sources of debt financing with the objective of minimizing its cost of borrowing. Comparative Figures Certain of the prior period’s figures may have been reclassified in conformity with the current period’s financial statement presentation. New Accounting Pronouncements (i) If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, but the substantial doubt is alleviated as a result of consideration of management’s plans, the entity should disclose information that enables users of the financial statements to understand all of the following: 1. Principal conditions or events that raised substantial doubt about the entity’s ability to continue as a going concern (before consideration of management’s plans). 2. Management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations. 3. Management’s plans that alleviated substantial doubt about the entity’s ability to continue as a going concern. If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, and substantial doubt is not alleviated after consideration of management’s plans, an entity should include a statement in the footnotes indicating that there is substantial doubt about the entity’s ability to continue as a going concern 1. Principal conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. 2. Management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations. 3. Management’s plans that are intended to mitigate the conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. This update will come into effect for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company is assessing the impact of this standard. (ii) In February, 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis which · Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met. · Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE). · Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The ASU will be effective for periods beginning after December 15, 2015, for public companies. Early adoption is permitted, including adoption in an interim period. The Company is assessing the impact of this standard.

MINERAL PROPERTY INTEREST	3. MINERAL PROPERTY INTEREST: Helmer-Bovill Property – Latah County, Idaho The Company entered into a purchase and sale agreement with Idaho Industrial Minerals LLC (“IIM”), a company in which one of the Company’s directors has a 25% interest, under which the Company had the right to acquire a 100% interest in 11 lease applications that comprise the Helmer-Bovill property by issuing to IIM a total of 1,750,000 shares of the Company. During fiscal 2009, 50,000 shares were issued in return for an extension of the agreement. During fiscal 2010, the terms of the agreement were further amended and the agreement was extended until August 2013. Under the terms of the amended agreement, the shares were to be issued based on certain development-based benchmarks being attained as follows: · 100,000 shares upon assignment of the mineral lease applications to the Company (issued); · 350,000 shares upon the State of Idaho issuing mineral leases to the Company (issued); · 600,000 shares upon the completion of a feasibility study (issued); and, · 700,000 shares upon completion of the permitting process necessary to construct and operate a mining facility (issued). On January 21, 2013, the Company issued the final 1,300,000 shares to IIM. With the issuances of the final tranches of shares, the Company has now fulfilled all its obligations under the purchase and sale agreement with IIM (Note 11). During the year ended April 30, 2012, the Company acquired an undivided 100% interest in two State of Idaho mineral leases contiguous to the Helmer-Bovill Property. The Company paid $10,000 and issued 50,000 shares at the fair value of $15,170. The State of Idaho mineral leases are subject to a 5% production royalty on gross sales.

The amount of bonus shares issued were subject to a minimum price of CAD$0.105 and a maximum of 1,720,649 bonus shares. In addition, the Company would issue the Lender an equal number of share purchase warrants for each loan tranche advanced. Each bonus share purchase warrant entitles the Lender to purchase one common share of the Company at a price equal to the greater of (a) the market price of the Company’s common shares on the date of the advance and (b) the volume weighted average price of the Company’s common shares over the twenty trading days immediately prior to the date of the advance.

Uncertain Tax Positions The Company has adopted certain provisions of ASC 740, “Income Taxes”, which prescribes a recognition threshold and measurement attribute for the recognition and measurement of tax positions taken or expected to be taken in income tax returns. The provisions also provide guidance on the de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, and accounting for interest and penalties associated with tax positions. The Company files income tax returns in the U.S. federal jurisdiction, various state and foreign jurisdictions. The Company’s tax returns are subject to tax examinations by U.S. federal and state tax authorities, or examinations by foreign tax authorities until respective statute of limitation. The Company currently has no tax years under examination. The Company is subject to tax examinations by tax authorities for all taxation years commencing after 2003. At April 30, 2016, the Company does not have an accrual relating to uncertain tax positions. It is not anticipated that unrecognized tax benefits would significantly increase or decrease within 12 months of the reporting date. Provision has not been made for U.S. or additional foreign taxes on undistributed earnings of foreign subsidiaries. Such earnings have been and will continue to be reinvested but could become subject to additional tax if they were remitted as dividends, or were loaned to the Company affiliate.

SUMMARY OF SIGNIFICANT ACCOUN21

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Apr. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries, i-Minerals USA, Inc. and CKD Ventures Ltd. All inter-company accounts and transactions have been eliminated. The Company’s fiscal year-end is April 30 th
Use of Estimates	Use of Estimates The preparation of these consolidated financial statements in conformity with US 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to the useful life and recoverability of long lived assets, stock-based compensation, amortization of Promissory Notes and Second Promissory Notes financing fees, valuation of derivative liabilities, and deferred income tax asset valuation allowances. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected.
Cash	Cash The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents. As at April 30, 2016 and 2015, the Company had no cash equivalents.
Equipment	Equipment Equipment is carried at cost and is amortized over the estimated useful economic lives using the declining balance method at an annual rate of 30%.
Mineral Property Acquisition Costs	Mineral Property Acquisition Costs Mineral property acquisition costs are capitalized when incurred and will be amortized using the units-of-production method following the commencement of production. If a mineral property is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment. The Company’s property has yet to reach the production stage. Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of mineral property claims.
Mineral Property Exploration Costs	Mineral Property Exploration Costs Mineral property exploration costs are expensed as incurred. When it has been determined that a mineral property can be economically developed as a result of establishing proven and probable reserves and all permits are received, the costs incurred to develop such property are capitalized. Such costs will be amortized using the units-of-production method over the estimated useful life of the probable reserve. If mineral properties are subsequently abandoned or impaired, any capitalized costs will be charged to operations.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Management tests long-lived assets to be held and used for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Impairment is considered to exist if the future cash flows on an undiscounted basis are less than the carrying amount of the long-lived asset. An impairment loss is measured and recorded based on the difference between book value and fair value of the asset group, as determined through the application of a present value technique using expected future cash flows to estimate fair value in the absence of a market price. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of cash flows from other asset groups.
Debt Issuance Costs	Debt Issuance Costs Debt issue costs in connection with debt financings are capitalized as an asset and amortized over the term of the debt using the effective interest method. Debt issuance costs paid to the purchaser of the debt are considered to be a reduction of the debt proceeds and a component of debt discount. Subsequently, the costs comprising this debt discount are amortized as financing fees over the term of the promissory notes using the effective interest method. During the year ended April 30, 2016, the Company amortized financing fees totaling $372,266 (2015 – $136,189).
Financial Instruments and Fair Value Measures	Financial Instruments and Fair Value Measures The book value of cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of those instruments. The fair value hierarchy under US GAAP is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 - observable inputs other than Level I, quoted prices for similar assets or liabilities in active prices whose inputs are observable or whose significant value drivers are observable; and Level 3 - assets and liabilities whose significant value drivers are unobservable by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s Promissory Notes and Second Promissory Notes are based on Level 2 inputs in the ASC 820 fair value hierarchy. The Company calculated the fair value of these instruments by discounting future cash flows using rates representative of current borrowing rates. At April 30, 2016, the Promissory Notes had a fair value of $5,659,462 (2015 – $5,479,007) and the Second Promissory Notes had a fair value of $5,044,374 (2015 - $1,532,123). The Company had certain Level 3 liabilities required to be recorded at fair value on a recurring basis in accordance with US GAAP as at April 30, 2016 and 2015. As at April 30, 2016, the Company’s Level 3 liabilities consisted of the warrants issued in connection with the Company’s offering of equity units in a private placement and warrants issued as financing fees as well as the grant of share purchase options to non-employees. The resulting Level 3 liabilities have no active market and are required to be measured at their fair value each reporting period based on information that is unobservable. A summary of the Company’s Level 3 liabilities for the years ended April 30, 2016 and 2015 is as follows: 2016 $ 2015 $ Warrants (Note 7) Beginning fair value 1,128,841 3,211,386 Issuance 176,493 130,890 Change in fair value (978,739) (2,213,435) Ending fair value 326,595 1,128,841 Non-employee options (Note 8(c)) Beginning fair value 116,615 68,859 Fair value of options granted 102,273 - Fair value of options on vesting 11,366 80,361 Change in fair value (41,047) (32,605) Ending fair value 189,207 116,615 Total Level 3 liabilities 515,802 1,245,456 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). There were no assets or liabilities measured at fair value on a nonrecurring basis during the years ended April 30, 2016 and 2015.
Earnings (Loss) Per Share	Earnings (Loss) Per Share The basic loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding. Diluted loss per common share is computed similar to basic loss per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For the year ended April 30, 2016, loss per share excludes 12,027,780 (2015 – 30,384,168) potentially dilutive common shares (related to outstanding options and warrants) as their effect was anti-dilutive
Foreign Currency Translation	Foreign Currency Translation The Company’s functional and reporting currency is the US dollar. Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the balance sheet date and non-monetary items are translated at exchange rates prevailing when the assets were acquired or obligations incurred. Gains and losses arising on translation or settlement of foreign currency denominated transactions or balances are included in the determination of income.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. The asset and liability method provides that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company records a valuation allowance to reduce deferred tax assets to the amount that is believed more likely than not to be realized. The Company has adopted the provisions of FASB ASC 740 "Income Taxes" regarding accounting for uncertainty in income taxes. The Company initially recognizes tax positions in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority, assuming full knowledge of the position and all relevant facts. Application requires numerous estimates based on available information. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, and its recognized tax positions and tax benefits may not accurately anticipate actual outcomes. As additional information is obtained, there may be a need to periodically adjust the recognized tax positions and tax benefits. These periodic adjustments may have a material impact on the consolidated statements of operations. When applicable, the Company classifies penalties and interest associated with uncertain tax positions as a component of income tax expense in its consolidated Statement of Income (Loss).
Stock-Based Compensation	Stock-Based Compensation The Company accounts for all stock-based payments and awards under the fair value based method. Stock-based payments to non-employees are measured at the fair value of the consideration received, or the fair value of the equity instruments issued, or liabilities incurred, whichever is more reliably measurable. The fair value of stock-based payments to non-employees is periodically re-measured until the counterparty performance is complete, and any change therein is recognized over the vesting period of the award and in the same manner as if the Company had paid cash instead of paying with or using equity based instruments. The cost of the stock-based payments to non-employees that are fully vested and non-forfeitable as at the grant date is measured and recognized at that date, unless there is a contractual term for services in which case such compensation would be amortized over the contractual term. The Company accounts for the granting of stock options to employees using the fair value method whereby all awards to employees will be recorded at fair value on the date of the grant. The fair value of all stock options is expensed over their vesting period with a corresponding increase to additional paid-in capital. Compensation costs for stock-based payments that do not include performance conditions are recognized on a straight-line basis. Compensation cost associated with a share based award having a performance condition is only recognized over the requisite service period if it is probable. Share based awards with a performance condition are accrued on an award by award basis. The Company uses the Black-Scholes option valuation model to calculate the fair value of stock options at the date of the grant. Option pricing models require the input of highly subjective assumptions, including the expected price volatility. Changes in these assumptions can materially affect the fair value estimates.
Derivative Liabilities	Derivative Liabilities The Company evaluates its financial instruments and other contracts to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for in accordance with ASC 815. The result of this accounting treatment is that the fair value of the embedded derivative is marked-to-market at each balance sheet date and recorded as a liability and the change in fair value is recorded in the consolidated statement of loss. Upon conversion or exercise of a derivative instrument, the instrument is marked to fair value at the conversion date and then that fair value is reclassified to equity. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. Derivative instruments that become subject to reclassification are reclassified at the fair value of the instrument on the reclassification date. Derivative instrument liabilities will be classified in the balance sheet as current or non-current based on whether or not settlement of the derivative instrument is expected within 12 months of the balance sheet date. The Company uses the Black-Scholes option valuation model to value derivative liabilities. This model uses Level 3 inputs in the fair value hierarchy established by ASC 820 Fair Value Measurement.
Concentration of Risk	Concentration of Risk The Company is subject to interest rate risk on its debt financings. The Company generally uses fixed interest rates for sources of debt financing with the objective of minimizing its cost of borrowing.
Comparative Figures	Comparative Figures Certain of the prior period’s figures may have been reclassified in conformity with the current period’s financial statement presentation.
New Accounting Pronouncements	New Accounting Pronouncements (i) If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, but the substantial doubt is alleviated as a result of consideration of management’s plans, the entity should disclose information that enables users of the financial statements to understand all of the following: 1. Principal conditions or events that raised substantial doubt about the entity’s ability to continue as a going concern (before consideration of management’s plans). 2. Management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations. 3. Management’s plans that alleviated substantial doubt about the entity’s ability to continue as a going concern. If conditions or events raise substantial doubt about an entity’s ability to continue as a going concern, and substantial doubt is not alleviated after consideration of management’s plans, an entity should include a statement in the footnotes indicating that there is substantial doubt about the entity’s ability to continue as a going concern 1. Principal conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. 2. Management’s evaluation of the significance of those conditions or events in relation to the entity’s ability to meet its obligations. 3. Management’s plans that are intended to mitigate the conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. This update will come into effect for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. The Company is assessing the impact of this standard. (ii) In February, 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis which · Placing more emphasis on risk of loss when determining a controlling financial interest. A reporting organization may no longer have to consolidate a legal entity in certain circumstances based solely on its fee arrangement, when certain criteria are met. · Reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE). · Changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The ASU will be effective for periods beginning after December 15, 2015, for public companies. Early adoption is permitted, including adoption in an interim period. The Company is assessing the impact of this standard.
