Basis of Presentation

Basis of Presentation	12 Months Ended
	May. 31, 2015
Basis of Presentation [Text Block]	1. Basis of Presentation Mantra Venture Group Ltd. (the “Company”) was incorporated in the State of Nevada on January 22, 2007 to acquire and commercially exploit various new energy related technologies through licenses and purchases. On December 8, 2008, the Company continued its corporate jurisdiction out of the State of Nevada and into the province of British Columbia, Canada. The Company is in the business of developing and providing energy alternatives. The Company also provides marketing and graphic design services to help companies optimize their environmental awareness presence through the eyes of government, industry and the general public. These consolidated financial statements have been prepared on a going concern basis, which implies the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The Company has yet to acquire commercially exploitable energy related technology, and is unlikely to generate earnings in the immediate or foreseeable future. The continuation of the Company as a going concern is dependent upon the continued financial support from its shareholders, the ability of management to raise additional equity capital through private and public offerings of its common stock, and the attainment of profitable operations. As at May 31, 2015, the Company has accumulated losses of $11,529,916 and a working capital deficit of $1,358,296. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. Management requires additional funds over the next twelve months to fully implement its business plan. Management is currently seeking additional financing through the sale of equity and from borrowings from private lenders to cover its operating expenditures. There can be no certainty that these sources will provide the additional funds required for the next twelve months.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	May. 31, 2015
Significant Accounting Policies [Text Block]	2. Significant Accounting Policies (a) Basis of Presentation/Principles of Consolidation These consolidated financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States. These consolidated financial statements include the accounts of the Company and its subsidiaries, Carbon Commodity Corporation, Climate ESCO Ltd., Mantra Energy Alternatives Ltd., Mantra China Inc., Mantra China Limited, Mantra Media Corp., Mantra NextGen Power Inc., and Mantra Wind Inc. All the subsidiaries are wholly-owned with the exception of Climate ESCO Ltd., which is 64.55% owned and Mantra Energy Alternatives Ltd., which is 88.21% owned. All inter- company balances and transactions have been eliminated. (b) Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to allowance for doubtful accounts, the estimated useful lives and recoverability of long-lived assets, valuation of inventory, equity component of convertible debt, stock-based compensation, 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. (c) Cash and Cash Equivalents The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents. (d) Accounts Receivable The Company recognizes allowances for doubtful accounts to ensure accounts receivable are not overstated due to the inability or unwillingness of its customers to make required payments. The allowance is based on historical bad debt expense, the age of receivable and the specific identification of receivables the Company considers at risk. The Company had no allowance for doubtful accounts as of May 31, 2015 and 2014. (e) Property and Equipment Property and equipment are stated at cost. The Company depreciates the cost of property and equipment over their estimated useful lives at the following annual rates: Automotive 3 years straight-line basis Computer equipment 3 years straight-line basis Leasehold improvements 5 years straight-line basis Office equipment and furniture 5 years straight-line basis Research equipment 5 years straight-line basis (f) Intangible Assets Intangible assets consist of patents and are stated at cost and have a definite life. Intangible assets are amortized over their estimated useful lives. The Company periodically evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the accounts. These assets are reviewed for impairment or obsolescence when events or changes in circumstances indicate that the carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows or other valuation techniques. The Company has no intangibles with indefinite lives. (g) Long-lived Assets In accordance with ASC 360, “ Property, Plant and Equipment (h) Foreign Currency Translation Transactions in foreign currencies are translated into the currency of measurement at the exchange rates in effect on the transaction date. Monetary balance sheet items expressed in foreign currencies are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The resulting exchange gains and losses are recognized in income. The Company’s integrated foreign subsidiaries are financially or operationally dependent on the Company. The Company uses the temporal method to translate the accounts of its integrated operations into U.S. dollars. Monetary assets and liabilities are translated at the exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average rates for the period, except for amortization, which is translated on the same basis as the related asset. The resulting exchange gains or losses are recognized in income. (i) Income Taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, “ Accounting for Income Taxes As of May 31, 2015 and 2014, the Company did not have any amounts recorded pertaining to uncertain tax positions. The Company files federal and provincial income tax returns in Canada and federal, state and local income tax returns in the U.S., as applicable. The Company may be subject to a reassessment of federal and provincial income taxes by Canadian tax authorities for a period of three years from the date of the original notice of assessment in respect of any particular taxation year. For Canadian and U.S. income tax returns, the open taxation years range from 2010 to 2015. In certain circumstances, the U.S. federal statute of limitations can reach beyond the standard three year period. U.S. state statutes of limitations for income tax assessment vary from state to state. Tax authorities of Canada and U.S. have not audited any of the Company’s, or its subsidiaries’, income tax returns for the open taxation years noted above. The Company recognizes interest and penalties related to uncertain tax positions in tax expense. During the years ended May 31, 2015 and 2014, there were no charges for interest or penalties. (j) Technology Development Revenue Recognition The Company performs research and development services. The Company recognizes revenue under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred, and collectability of the contract price is considered reasonably assured and can be reasonably estimated. Revenue is based on direct labor hours expended at contract billing rates plus other billable direct costs. (k) Research and Development Costs Research and development costs are expensed as incurred. (l) Stock-based Compensation The Company records stock-based compensation in accordance with ASC 718, “ Compensation – Stock Compensation The Company uses the Black-Scholes option pricing model to calculate the fair value of stock-based awards. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the consolidated statement of operations over the requisite service period. (m) Loss Per Share The Company computes loss per share in accordance with ASC 260, " Earnings per Share (n) Comprehensive Loss ASC 220, “ Comprehensive Income (o) Recent Accounting Pronouncements The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations. (p) Fair Value Measurements The Company measures and discloses the estimated fair value of financial assets and liabilities using the fair value hierarchy prescribed by US generally accepted accounting principles. The fair value hierarchy has three levels, which are based on reliable available inputs of observable data. The hierarchy requires the use of observable market data when available. The three-level hierarchy is defined as follows: Level 1 – quoted prices for identical instruments in active markets. Level 2 – quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations in which significant inputs and significant value drivers are observable in active markets; and. Level 3 – fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Financial instruments consist principally of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, loans payable and convertible debentures. Derivative liabilities are determined based on “Level 3” inputs, which are significant and unobservable and have the lowest priority. There were no transfers into or out of “Level 3” during the year ended May 31, 2015 and 2014. The recorded values of all other financial instruments approximate their current fair values because of their nature and respective relatively short maturity dates or durations. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial statement. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. See Note 10 for additional information. (q) Derivative Liabilities The Company accounts for derivative instruments in accordance with ASC Topic 815, “ Derivatives and Hedging

Derivative Liabilities

Derivative Liabilities	12 Months Ended

Derivative Liabilities [Text Block]	10. Derivative Liabilities The embedded conversion option of the convertible debenture described in Note 9(g) contains a conversion feature that qualifies for embedded derivative classification. The fair value of the liability will be re-measured at the end of every reporting period and the change in fair value will be reported in the statement of operations as a gain or loss on derivative financial instruments. Upon the issuance of the convertible note payable described in Note 9(g), the Company concluded that it only has sufficient shares to satisfy the conversion of some but not all of the outstanding convertible notes, warrants and options. The Company elected to reclassify contracts from equity with the earliest inception date first. As a result none of the Company’s previously outstanding convertible instruments qualified for derivative reclassification, however, any convertible securities issued after the election would qualify for treatment as derivative liabilities. The Company reassesses the classification of the instruments at each balance sheet date. If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification. The table below sets forth a summary of changes in the fair value of the Company’s Level 3 financial liabilities: May 31, 2015 May 31, 2014 Balance at the beginning of period $ – $ – Addition of new derivative liabilities (embedded conversion options) 160,244 – Change in fair value of embedded conversion option 193,424 – Balance at the end of the period $ 353,668 $ – The following table summarizes the change in fair value of derivatives: May 31, 2015 May 31, 2014 Fair value of derivative liabilities in excess of note proceeds received $ (35,244 ) $ – Change in fair value of derivative liabilities during period (193,424 ) – Change in fair value of derivatives $ (228,668 ) $ – The Company uses Level 2 inputs for its valuation methodology for the embedded conversion option liabilities as their fair values were determined by using the Black-Scholes option pricing model based on various assumptions. The model incorporates the price of a share of the Company’s common stock (as quoted on the Over the Counter Bulletin Board), volatility, risk free rate, dividend rate and estimated life. Significant changes in any of these inputs in isolation would result in a significant change in the fair value measurement. As required, these are classified based on the lowest level of input that is significant to the fair value measurement. The following table shows the assumptions used in the calculations: Expected Expected Expected Risk-free Interest Dividend Life (in Volatility Rate Yield years) At issuance 124% 0.07% 0% 0.50 At May 31, 2015 133% 0.10% 0% 0.21

Commitments and Contingencies (a) On September 2, 2009, the Company entered into an agreement with a company to acquire a worldwide, exclusive license for the Mixed Reactant Flow-By Fuel Cell technology. The term of the agreement is for twenty years or the expiry of the last patent licensed under the agreement, whichever is later. The Company agreed to pay the licensor the following license fees: • an initial license fee of Cdn$10,000 payable in two installments: Cdn$5,000 upon execution of the agreement (paid) and Cdn$5,000 within thirty days of September 2, 2009 (paid); • a further license fee of Cdn$15,000 (paid) to be paid within ninety days of September 2, 2009; and • an annual license fee, payable annually on the anniversary of the date of the agreement as follows: September 1, 2010 Cdn$10,000 (paid) September 1, 2011 Cdn$20,000 (accrued) September 1, 2012 Cdn$30,000(accrued) September 1, 2013 Cdn$40,000 (accrued) September 1, 2014 Cdn$50,000 (accrued) and each successive anniversary The Company is to pay the licensor a royalty calculated as 2% of the gross revenue and 15% of any and all consideration directly or indirectly received by the Company from the grant of any sublicense rights. The Company will pay interest at a rate of 1% per month on any amounts past due. In addition, the Company is responsible for the timely payment of all future costs relating to patent expenses and any new or useful art, process, machine, manufacture or composition of matter arising out of any licensor improvements or joint improvements licensed under this agreement and identified by the licensor as potentially patentable. The Company must also invest a minimum of Cdn$250,000 in research and development directly associated with the technology. (b) On May 23, 2012, a former employee of the Company delivered a Notice of Application seeking judgment against the Company for approximately $55,000. The hearing of that Application took place on July 31, 2012, at which time the former employee obtained judgment in the approximate amount of $55,000. The Company did not defend the amount of the judgment and the amount is included in accounts payable, but claims a complete set-off on the basis that the former employee retains 1,000,000 shares of common stock of the Company as security for payment of the outstanding consulting fees owed to him. On August 31, 2012, the Company commenced a separate action against the former employee seeking a return of the 1,000,000 shares of common stock and a stay of execution of the judgment. That application is pending and has not yet been heard or determined by the court. The payment of the judgment claim of approximately $55,000 is dependent upon whether the former employee will first return the 1,000,000 shares of common stock noted above. The probable outcome of the Company’s claim for the return of the shares cannot yet be determined. (c) On May 7, 2014, the Company entered into a two year office space lease commencing July 1, 2014.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	May. 31, 2015
Basis of Presentation/Principles of Consolidation [Policy Text Block]	(a) Basis of Presentation/Principles of Consolidation These consolidated financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States. These consolidated financial statements include the accounts of the Company and its subsidiaries, Carbon Commodity Corporation, Climate ESCO Ltd., Mantra Energy Alternatives Ltd., Mantra China Inc., Mantra China Limited, Mantra Media Corp., Mantra NextGen Power Inc., and Mantra Wind Inc. All the subsidiaries are wholly-owned with the exception of Climate ESCO Ltd., which is 64.55% owned and Mantra Energy Alternatives Ltd., which is 88.21% owned. All inter- company balances and transactions have been eliminated.
Use of Estimates [Policy Text Block]	(b) Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions related to allowance for doubtful accounts, the estimated useful lives and recoverability of long-lived assets, valuation of inventory, equity component of convertible debt, stock-based compensation, 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 and Cash Equivalents [Policy Text Block]	(c) Cash and Cash Equivalents The Company considers all highly liquid instruments with maturity of three months or less at the time of issuance to be cash equivalents.
Accounts Receivable [Policy Text Block]	(d) Accounts Receivable The Company recognizes allowances for doubtful accounts to ensure accounts receivable are not overstated due to the inability or unwillingness of its customers to make required payments. The allowance is based on historical bad debt expense, the age of receivable and the specific identification of receivables the Company considers at risk. The Company had no allowance for doubtful accounts as of May 31, 2015 and 2014.
Property and Equipment [Policy Text Block]	(e) Property and Equipment Property and equipment are stated at cost.

Intangible Assets [Policy Text Block]	(f) Intangible Assets Intangible assets consist of patents and are stated at cost and have a definite life. Intangible assets are amortized over their estimated useful lives. The Company periodically evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the accounts. These assets are reviewed for impairment or obsolescence when events or changes in circumstances indicate that the carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows or other valuation techniques. The Company has no intangibles with indefinite lives.
Long-lived Assets [Policy Text Block]	(g) Long-lived Assets In accordance with ASC 360, “ Property, Plant and Equipment
Foreign Currency Translation [Policy Text Block]	(h) Foreign Currency Translation Transactions in foreign currencies are translated into the currency of measurement at the exchange rates in effect on the transaction date. Monetary balance sheet items expressed in foreign currencies are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. The resulting exchange gains and losses are recognized in income. The Company’s integrated foreign subsidiaries are financially or operationally dependent on the Company. The Company uses the temporal method to translate the accounts of its integrated operations into U.S. dollars. Monetary assets and liabilities are translated at the exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at average rates for the period, except for amortization, which is translated on the same basis as the related asset. The resulting exchange gains or losses are recognized in income.
Income Taxes [Policy Text Block]	(i) Income Taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC 740, “ Accounting for Income Taxes As of May 31, 2015 and 2014, the Company did not have any amounts recorded pertaining to uncertain tax positions.
Technology Development Revenue Recognition [Policy Text Block]	(j) Technology Development Revenue Recognition The Company performs research and development services. The Company recognizes revenue under research contracts when a contract has been executed, the contract price is fixed and determinable, delivery of services or products has occurred, and collectability of the contract price is considered reasonably assured and can be reasonably estimated. Revenue is based on direct labor hours expended at contract billing rates plus other billable direct costs.
Research and Development Costs [Policy Text Block]	(k) Research and Development Costs Research and development costs are expensed as incurred.
Stock-based Compensation [Policy Text Block]	(l) Stock-based Compensation The Company records stock-based compensation in accordance with ASC 718, “ Compensation – Stock Compensation The Company uses the Black-Scholes option pricing model to calculate the fair value of stock-based awards. This model is affected by the Company’s stock price as well as assumptions regarding a number of subjective variables. These subjective variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The value of the portion of the award that is ultimately expected to vest is recognized as an expense in the consolidated statement of operations over the requisite service period.
Loss Per Share [Policy Text Block]	(m) Loss Per Share The Company computes loss per share in accordance with ASC 260, " Earnings per Share
Comprehensive Loss [Policy Text Block]	(n) Comprehensive Loss ASC 220, “ Comprehensive Income
Recent Accounting Pronouncements [Policy Text Block]	(o) Recent Accounting Pronouncements The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations.
Fair Value Measurements [Policy Text Block]	(p) Fair Value Measurements The Company measures and discloses the estimated fair value of financial assets and liabilities using the fair value hierarchy prescribed by US generally accepted accounting principles. The fair value hierarchy has three levels, which are based on reliable available inputs of observable data. The hierarchy requires the use of observable market data when available. The three-level hierarchy is defined as follows: Level 1 – quoted prices for identical instruments in active markets. Level 2 – quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations in which significant inputs and significant value drivers are observable in active markets; and. Level 3 – fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Financial instruments consist principally of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, loans payable and convertible debentures. Derivative liabilities are determined based on “Level 3” inputs, which are significant and unobservable and have the lowest priority. There were no transfers into or out of “Level 3” during the year ended May 31, 2015 and 2014. The recorded values of all other financial instruments approximate their current fair values because of their nature and respective relatively short maturity dates or durations. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial statement. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. See Note 10 for additional information.
Derivative Liabilities [Policy Text Block]	(q) Derivative Liabilities The Company accounts for derivative instruments in accordance with ASC Topic 815, “ Derivatives and Hedging
