Accounting Policies [Abstract]
Significant Accounting Policies	2) SIGNFICANT ACCOUNTING POLICIES Basis of Presentation This summary of significant accounting policies is presented to assist in understanding the financial statements. The financial statements and notes are representations of the Company’s management, which is responsible for their integrity and objectivity. These financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States. Principles of consolidation These financial statements include the accounts of the Company, its wholly owned subsidiary RadMax Technologies, Inc., and its previously wholly owned subsidiary Rand Energy Group Inc. (“Rand”). All significant inter-company balances and transactions have been eliminated upon consolidation. Investment in associates Investments in which the Company has the ability to exert significant influence but does not have control are accounted for using the equity method whereby the original cost of the investment is adjusted annually for the Company’s share of earnings, losses and dividends during the current year. The Company entered into a Mutual Accord and Purchase Agreement on March 7, 2018, to sell all of its interest in Minewest Silver & Gold Inc. (“Minewest”), a British Columbia company, in exchange for settlement of its outstanding debt of $7,217 to Minewest. The Company completed the final transfer of mining rights and Claim titles to Minewest on August 13, 2018. Risks and uncertainties The Company operates in an emerging industry that is subject to market acceptance and technological change. The Company’s operations are subject to significant risks and uncertainties, including financial, operational, technological and other risks associated with operating an emerging business, including the potential risk of business failure. Cash and cash equivalents For the purposes of the statement of cash flows, the Company considers all highly liquid investments with original maturities of three months or less when acquired to be cash equivalents. Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification (ASC) Topic 606: Revenue from Contracts with Customers. Revenue is recognized using the following five-step model: (i) identification of the promised goods in the contract; (ii) determination of whether the promised goods are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company applies this model when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Under Topic 606, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. The Company’s contracts with customers typically contain a single performance obligation. A contract’s transaction price is recognized as revenue when, or as, the performance obligation is satisfied. The Company considers the contractual consideration payable by the customer when determining the transaction price of each contract. Revenue is recorded net of charges for certain sales incentives and discounts, and applicable state and local sales taxes, which represent components of the transaction price. Charges are estimated upon shipment of the product based on contractual terms, and actual charges typically do not vary materially from our estimates. Shipping estimates are determined by utilizing shipping costs provided by the various service providers websites based on number of packages, weight and destination. Shipping costs are included in the cost of goods sold as the revenue is captured in total sales. The Company receives payments from customers based on the terms established in the Company’s contracts. When amounts are billed and collected before a performance obligation has been satisfied, they are included in deferred revenue. Performance obligations for product sales are satisfied as of a point in time. Revenue is recognized when control of the product transfers to the customer, generally upon product shipment. Performance obligations for site support and engineering services are satisfied over-time if the customer receives the benefits as we perform work and we have a contractual right to payment. Revenue recognized on an over-time basis is based on costs incurred to date relative to milestones and total estimated costs at completion to measure progress. The Company product revenue includes compressors and expanders. the Company also provides direct site support and engineering services to customers, such as repair and upgrade of its products. During the year ended April 30, 2019 Company’s revenue was $60,000 from sale of prototypes. There was no revenue during the year ended April 30, 2018. During the year ended April 30, 2019, revenue was earned from a single contract with one customer. As of April 30, 2019, the Company had a deferred revenue balance of $25,000 from this customer related to deliverables in progress at that date. Furniture and equipment Property and equipment are stated at cost, which includes the acquisition price and any direct costs to bring the asset into use at its intended location, less accumulated amortization. Depreciation of property and equipment is calculated using the straight-line method to write off the cost, net of any estimated residual value, over their estimated useful lives of the assets as follows: Office equipment 5 years and electronic equipment 3 years. Depreciation of office equipment is included in general and administrative expenses; Depreciation of research equipment is included in research and development expense. Fair value of financial instruments The carrying values of cash and cash equivalents, amounts due to related parties and accounts payable approximate their fair values because of the short-term maturity of these financial instruments. Fair value measurements ASC Topic 820, “Fair Value Measurements and Disclosures,” requires disclosure of the fair value of financial instruments held by the Company. ASC Topic 825, “Financial Instruments,” defines fair value, and establishes a three-level valuation hierarchy for disclosures of fair value measurement that enhances disclosure requirements for fair value measures. When required to measure assets or liabilities at fair value, the Company uses a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used. The Company determines the level within the fair value hierarchy in which the fair value measurements in their entirety fall. The categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1 uses quoted prices in active markets for identical assets or liabilities, Level 2 uses significant other observable inputs, and Level 3 uses significant unobservable inputs. The amount of the total gains or losses for the period are included in earnings that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date. Derivative instruments The Company has financing arrangements that contain freestanding derivative instruments or hybrid instruments that contained embedded derivative features. In accordance with U.S. GAAP, derivative instruments and hybrid instruments are recognized as either assets or liabilities in the Company’s balance sheet and are measured at fair value with gains or losses recognized in earnings depending on the nature of the derivative or hybrid instruments. Embedded derivatives that are not clearly and closely related to the host contract are bifurcated and recognized at fair value with changes in fair value recognized as either a gain or loss in earnings if they can be reliably measured. When the fair value of embedded derivative features cannot be reliably measured, the Company measures and reports the entire hybrid instrument at fair value with changes in fair value recognized as either a gain or loss in earnings. The Company determines the fair value of derivative instruments and hybrid instruments based on available market data using a Black Scholes model, giving consideration to all of the rights and obligations of each instrument and precluding the use of “blockage” discounts or premiums in determining the fair value of a large block of financial instruments. Fair value under these conditions does not necessarily represent fair value determined using valuation standards that give consideration to blockage discounts and other factors that may be considered by market participants in establishing fair value Interest Rate Risk The Company is not exposed to significant interest rate risk due to the short-term maturity of its monetary assets and liabilities. Credit Risk The Company’s financial asset that is exposed to credit risk consists primarily of cash. To manage the risk, cash is placed with major financial institutions. Currency Risk The Company’s functional currency is the US dollar and the 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. Gains and losses arising on translation or settlement of foreign currency denominated transactions or balances are included in the determination of income. Foreign currency transactions are primarily undertaken in US dollars. The Company has not, to the date of these consolidated financial statements, entered into derivative instruments to offset the impact of foreign currency fluctuations. For reporting purposes assets and liabilities with Canadian dollar as functional currency are translated into US dollar at the period end rates of exchange, and the results of the operations are translated at average rates of exchange for the period. The resulting translation adjustments are included the Company’s consolidated statements of operations and comprehensive loss. and stated in US dollars. Income taxes Deferred income taxes are reported for timing differences between items of income or expense reported in the consolidated financial statements and those reported for income tax purposes in accordance with ASC 740, “Income Taxes”, which requires the use of the asset/liability method of accounting for income taxes. Deferred income taxes and tax benefits are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases, and for tax losses and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company provides for deferred taxes for the estimated future tax effects attributable to temporary differences and carry-forwards when realization is more likely than not. Basic and diluted net loss per share Basic EPS is computed by dividing net income (loss) available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible debt using the if-converted method. In computing diluted EPS, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Diluted EPS excludes all dilutive potential shares if their effect is anti-dilutive. Stock-based compensation The Company accounts for stock-based compensation in accordance with FASB ASC 718 which establishes the accounting treatment for transactions in which an entity exchanges its equity instruments for goods or services. Under the provisions of FASB ASC 718, e measurement of the value of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. Non-employee stock-based compensation is granted at the Board of Director’s discretion to award select consultants for exceptional performance. Prior to issuance of the awards, the Company is not under any obligation to issue the stock options. The award vests over a specified period determined by the Company’s Board of Directors. The measurement date of the grant is also the date of the award. The fair value of options is expensed ratably during the specified vesting period. The Company estimates the fair value of employee stock option awards on the date of grant using a Black-Scholes valuation model which requires management to make certain assumptions regarding: (i) the expected volatility in the market price of the Company’s common stock; (ii) dividend yield; (iii) risk-free interest rates; and (iv) the period of time employees are expected to hold the award prior to exercised (referred to as the expected holding period). The expected volatility under this valuation model is based on the current and historical implied volatilities of the Company’s common stock. The dividend yield is based on the approved annual dividend rate in effect and current market price of the underlying common stock at the time of grant. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for bonds with maturities ranging from one month to five years. The expected holding period of the awards granted is estimated using the historical exercise behavior of employees. In addition, the Company estimates the expected impact of forfeited awards and recognize stock-based compensation cost only for those awards expected to vest. The Company utilizes historical experience to estimate projected forfeitures. If actual forfeitures are materially different from estimates, stock-based compensation expense could be significantly different from what we have recorded in the current period. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in the period of the revision. The Company accounts for share-based payments to non-employees in accordance with FASB ASC 505-50. Stock Granted to Employees and Non-Employees in Lieu of Cash Payments The Company periodically issues shares of its common stock in lieu of cash payments to certain consultants, vendors and employees. The Company follows financial accounting standards that require the measurement of the value of services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. Use of estimates The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management assumptions and estimates relate to long-lived asset impairments and stock-based compensation valuation. Actual results could differ from these estimates and assumptions and could have a material effect on the Company’s reported financial position and results of operations. Research and development costs Research and development costs are expensed as incurred. Related Parties In accordance with ASC 850 “Related Party Disclosure”, a party is considered to be related to the Company if the party directly or indirectly or through one or more intermediaries, controls, is controlled by, or is under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal with if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. Reclassifications Certain reclassifications have been made to the prior year financial information to conform to the presentation used in the financial statements for the year ended April 30, 2019. New Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the provisions of the pronouncement effective March 1, 2018 and it did not result in a material change to the statement of cash flows. In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. There was no impact to the financial statements upon adoption of this update effective May 1, 2018. In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company will apply the provisions of the update to potential future acquisitions occurring after the effective date. In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation, Improvements to Nonemployee Share-Based Payment Accounting. ASU No. 2018-07 aligns accounting for share-based payment transactions for acquiring goods and services from nonemployees with transaction with employees. The update is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02 Leases (Subtopic 842), which will require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by most leases. The update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The ASU will be effective for the Company in the first quarter of fiscal year 2020. We are currently evaluating the impact of the guidance on the Company’s consolidated financial statements. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

Going Concern	3) GOING CONCERN The Company incurred a net loss of $2,259,996 for the year ended April 30, 2019 and has a working capital deficit of $2,224,460 and an accumulated deficit of $26,323,395 at April 30, 2019. These factors raise substantial doubt about the ability of the Company to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. As a result, the Company’s consolidated financial statements as of April 30, 2019 and for the year ended have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The Company also receives interim support from related parties and plans to raise additional capital through debt and/or equity financings. There is no assurance that any of these activities will be successful. There continues to be insufficient funds to provide enough working capital to fund ongoing operations for the next twelve months.

Earnings Per Share	4) EARNINGS PER SHARE Basic Earnings Per Share (“EPS”) is computed as net income (loss) available to common stockholders divided by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur from common shares issuable through stock options and warrants. The outstanding securities at April 30, 2019 and 2018 that could have a dilutive effect are as follows: April 30, 2019 April 30, 2018 Stock options 8,200,000 9,355,000 Convertible notes and accrued interest, non-related parties 19,520,948 13,167,649 Convertible notes and accrued interest, related parties 5,881,314 6,336,522 TOTAL POSSIBLE DILUTIVE SHARES 33,602,262 28,859,171 For the year ended April 30, 2019 and 2018, respectively, the effect of the Company’s outstanding stock options would have been anti-dilutive and so are excluded in the diluted EPS.

(Note 7). Management has determined that these provisions cause the conversion options to require derivative liability accounting. The First Fire Note contained provisions which, after 180 days from the date of issuance, called for the debt conversion exercise price to be the lower of $0.10 per share or seventy-five percent (75%) of the lowest traded price of the Company’s common stock during the twenty consecutive trade days immediately preceding the date of a conversion. Management valued that portion of derivative liability associated with the Firstfire Note at fair value of the derivative at the earliest date in which the holder of the note would have been eligible to convert the note to shares of the Company’s stock. The Company utilized the assumptions in determining fair value of the initial derivative liability associated with the First Fire Note: Stock price $ 0.0675 Conversion price 0.045075 Expected volatility 122.25 % Expected term (years) 0.337 Risk free rate 2.28 % Fair value of conversion option derivative units $ 106,117 The Company recognized loss on initial recording of the conversion derivative liability of $106,117 and concurrently recorded an unamortized discount on the derivative liability of $150,000, to be amortized over the remaining life of the note.

The Labrys Note contained provisions which called for the debt conversion exercise price to be sixty percent (60%) of the lowest traded price of the Company’s common stock during the twenty consecutive trade days immediately preceding the date of a conversion.

Income Tax Disclosure [Abstract]
Income Taxes	16) INCOME TAXES The Company is subject to the income tax laws of the United States and the States of Washington and Oregon, and uses the liability method, where deferred tax assets and liabilities are determined based on the expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities for financial and income tax reporting purposes. On December 22, 2017, the U.S. Tax Cuts and Jobs Act (the “Tax Reform Act”) was signed into law by President Trump. The Tax Reform Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21% effective January 1, 2018, while also repealing the deduction for domestic production activities, implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted. The Company does not anticipate that the “Tax Reform Act” will have any substantial effect on the Company’s financial position in the near future. The cumulative net operating loss carryforward is approximately $3,005,229 for the year ended April 2018 and will begin expiring in 2037. Section 382 of the Internal Revenue Code generally imposes an annual limitation on the amount of net operating loss carryforwards that may be used to offset taxable income when a corporation has undergone significant changes in its stock ownership. The Company estimates that the Net operating loss for the year ended April 30, 2019 is $2,259,996. Deferred tax assets consist of the tax effect of NOL carry-forwards. The Company has provided a full valuation allowance on the deferred tax assets because of the uncertainty regarding its realizability. Deferred tax assets consist of the following: The composition of REGI’s deferred tax assets at April 30, 2019 and 2018 is as follows: April 30, 2019 April 30, 2018 Net operating loss carryforward $ 5,532,897 $ 3,272,901 Deferred tax asset $ 1,161,908 $ 687,309 Valuation allowance (1,161,908 ) (687,309 ) DEFERRED TAX ASSET $ - $ - Management has determined that the Company is subject to examination of income tax filings in the United States for the 2015 through 2017 tax years.

Significant Accounting Policies (Policies)	Apr. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation This summary of significant accounting policies is presented to assist in understanding the financial statements. The financial statements and notes are representations of the Company’s management, which is responsible for their integrity and objectivity. These financial statements and related notes are presented in accordance with accounting principles generally accepted in the United States.
Principles of Consolidation	Principles of consolidation These financial statements include the accounts of the Company, its wholly owned subsidiary RadMax Technologies, Inc., and its previously wholly owned subsidiary Rand Energy Group Inc. (“Rand”). All significant inter-company balances and transactions have been eliminated upon consolidation.
Investment in Associates	Investment in associates Investments in which the Company has the ability to exert significant influence but does not have control are accounted for using the equity method whereby the original cost of the investment is adjusted annually for the Company’s share of earnings, losses and dividends during the current year. The Company entered into a Mutual Accord and Purchase Agreement on March 7, 2018, to sell all of its interest in Minewest Silver & Gold Inc. (“Minewest”), a British Columbia company, in exchange for settlement of its outstanding debt of $7,217 to Minewest. The Company completed the final transfer of mining rights and Claim titles to Minewest on August 13, 2018.
Risks and Uncertainties	Risks and uncertainties The Company operates in an emerging industry that is subject to market acceptance and technological change. The Company’s operations are subject to significant risks and uncertainties, including financial, operational, technological and other risks associated with operating an emerging business, including the potential risk of business failure.
Cash and Cash Equivalents	Cash and cash equivalents For the purposes of the statement of cash flows, the Company considers all highly liquid investments with original maturities of three months or less when acquired to be cash equivalents.
Revenue Recognition	Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification (ASC) Topic 606: Revenue from Contracts with Customers. Revenue is recognized using the following five-step model: (i) identification of the promised goods in the contract; (ii) determination of whether the promised goods are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company applies this model when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Under Topic 606, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the customer. The Company’s contracts with customers typically contain a single performance obligation. A contract’s transaction price is recognized as revenue when, or as, the performance obligation is satisfied. The Company considers the contractual consideration payable by the customer when determining the transaction price of each contract. Revenue is recorded net of charges for certain sales incentives and discounts, and applicable state and local sales taxes, which represent components of the transaction price. Charges are estimated upon shipment of the product based on contractual terms, and actual charges typically do not vary materially from our estimates. Shipping estimates are determined by utilizing shipping costs provided by the various service providers websites based on number of packages, weight and destination. Shipping costs are included in the cost of goods sold as the revenue is captured in total sales. The Company receives payments from customers based on the terms established in the Company’s contracts. When amounts are billed and collected before a performance obligation has been satisfied, they are included in deferred revenue. Performance obligations for product sales are satisfied as of a point in time. Revenue is recognized when control of the product transfers to the customer, generally upon product shipment. Performance obligations for site support and engineering services are satisfied over-time if the customer receives the benefits as we perform work and we have a contractual right to payment. Revenue recognized on an over-time basis is based on costs incurred to date relative to milestones and total estimated costs at completion to measure progress. The Company product revenue includes compressors and expanders. the Company also provides direct site support and engineering services to customers, such as repair and upgrade of its products. During the year ended April 30, 2019 Company’s revenue was $60,000 from sale of prototypes. There was no revenue during the year ended April 30, 2018. During the year ended April 30, 2019, revenue was earned from a single contract with one customer. As of April 30, 2019, the Company had a deferred revenue balance of $25,000 from this customer related to deliverables in progress at that date.
Furniture and Equipment	Furniture and equipment Property and equipment are stated at cost, which includes the acquisition price and any direct costs to bring the asset into use at its intended location, less accumulated amortization. Depreciation of property and equipment is calculated using the straight-line method to write off the cost, net of any estimated residual value, over their estimated useful lives of the assets as follows: Office equipment 5 years and electronic equipment 3 years. Depreciation of office equipment is included in general and administrative expenses; Depreciation of research equipment is included in research and development expense.
Fair Value of Financial Instruments	Fair value of financial instruments The carrying values of cash and cash equivalents, amounts due to related parties and accounts payable approximate their fair values because of the short-term maturity of these financial instruments.
Fair Value Measurements	Fair value measurements ASC Topic 820, “Fair Value Measurements and Disclosures,” requires disclosure of the fair value of financial instruments held by the Company. ASC Topic 825, “Financial Instruments,” defines fair value, and establishes a three-level valuation hierarchy for disclosures of fair value measurement that enhances disclosure requirements for fair value measures. When required to measure assets or liabilities at fair value, the Company uses a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used. The Company determines the level within the fair value hierarchy in which the fair value measurements in their entirety fall. The categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Level 1 uses quoted prices in active markets for identical assets or liabilities, Level 2 uses significant other observable inputs, and Level 3 uses significant unobservable inputs. The amount of the total gains or losses for the period are included in earnings that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date.
Derivative Instruments	Derivative instruments The Company has financing arrangements that contain freestanding derivative instruments or hybrid instruments that contained embedded derivative features. In accordance with U.S. GAAP, derivative instruments and hybrid instruments are recognized as either assets or liabilities in the Company’s balance sheet and are measured at fair value with gains or losses recognized in earnings depending on the nature of the derivative or hybrid instruments. Embedded derivatives that are not clearly and closely related to the host contract are bifurcated and recognized at fair value with changes in fair value recognized as either a gain or loss in earnings if they can be reliably measured. When the fair value of embedded derivative features cannot be reliably measured, the Company measures and reports the entire hybrid instrument at fair value with changes in fair value recognized as either a gain or loss in earnings. The Company determines the fair value of derivative instruments and hybrid instruments based on available market data using a Black Scholes model, giving consideration to all of the rights and obligations of each instrument and precluding the use of “blockage” discounts or premiums in determining the fair value of a large block of financial instruments. Fair value under these conditions does not necessarily represent fair value determined using valuation standards that give consideration to blockage discounts and other factors that may be considered by market participants in establishing fair value
Interest Rate Risk	Interest Rate Risk The Company is not exposed to significant interest rate risk due to the short-term maturity of its monetary assets and liabilities.
Credit Risk	Credit Risk The Company’s financial asset that is exposed to credit risk consists primarily of cash. To manage the risk, cash is placed with major financial institutions.
Currency Risk	Currency Risk The Company’s functional currency is the US dollar and the 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. Gains and losses arising on translation or settlement of foreign currency denominated transactions or balances are included in the determination of income. Foreign currency transactions are primarily undertaken in US dollars. The Company has not, to the date of these consolidated financial statements, entered into derivative instruments to offset the impact of foreign currency fluctuations. For reporting purposes assets and liabilities with Canadian dollar as functional currency are translated into US dollar at the period end rates of exchange, and the results of the operations are translated at average rates of exchange for the period. The resulting translation adjustments are included the Company’s consolidated statements of operations and comprehensive loss. and stated in US dollars.
Income Taxes	Income taxes Deferred income taxes are reported for timing differences between items of income or expense reported in the consolidated financial statements and those reported for income tax purposes in accordance with ASC 740, “Income Taxes”, which requires the use of the asset/liability method of accounting for income taxes. Deferred income taxes and tax benefits are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases, and for tax losses and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company provides for deferred taxes for the estimated future tax effects attributable to temporary differences and carry-forwards when realization is more likely than not.
Basic and Diluted Net Loss Per Share	Basic and diluted net loss per share Basic EPS is computed by dividing net income (loss) available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible debt using the if-converted method. In computing diluted EPS, the average stock price for the period is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. Diluted EPS excludes all dilutive potential shares if their effect is anti-dilutive.
Stock-based Compensation	Stock-based compensation The Company accounts for stock-based compensation in accordance with FASB ASC 718 which establishes the accounting treatment for transactions in which an entity exchanges its equity instruments for goods or services. Under the provisions of FASB ASC 718, e measurement of the value of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. Non-employee stock-based compensation is granted at the Board of Director’s discretion to award select consultants for exceptional performance. Prior to issuance of the awards, the Company is not under any obligation to issue the stock options. The award vests over a specified period determined by the Company’s Board of Directors. The measurement date of the grant is also the date of the award. The fair value of options is expensed ratably during the specified vesting period. The Company estimates the fair value of employee stock option awards on the date of grant using a Black-Scholes valuation model which requires management to make certain assumptions regarding: (i) the expected volatility in the market price of the Company’s common stock; (ii) dividend yield; (iii) risk-free interest rates; and (iv) the period of time employees are expected to hold the award prior to exercised (referred to as the expected holding period). The expected volatility under this valuation model is based on the current and historical implied volatilities of the Company’s common stock. The dividend yield is based on the approved annual dividend rate in effect and current market price of the underlying common stock at the time of grant. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for bonds with maturities ranging from one month to five years. The expected holding period of the awards granted is estimated using the historical exercise behavior of employees. In addition, the Company estimates the expected impact of forfeited awards and recognize stock-based compensation cost only for those awards expected to vest. The Company utilizes historical experience to estimate projected forfeitures. If actual forfeitures are materially different from estimates, stock-based compensation expense could be significantly different from what we have recorded in the current period. The cumulative effect on current and prior periods of a change in the estimated forfeiture rate is recognized as compensation cost in the period of the revision. The Company accounts for share-based payments to non-employees in accordance with FASB ASC 505-50.
Stock Granted to Employees and Non-Employees in Lieu of Cash Payments	Stock Granted to Employees and Non-Employees in Lieu of Cash Payments The Company periodically issues shares of its common stock in lieu of cash payments to certain consultants, vendors and employees. The Company follows financial accounting standards that require the measurement of the value of services received in exchange for an award of an equity instrument based on the grant-date fair value of the award.
Use of Estimates	Use of estimates The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management assumptions and estimates relate to long-lived asset impairments and stock-based compensation valuation. Actual results could differ from these estimates and assumptions and could have a material effect on the Company’s reported financial position and results of operations.
Research and Development Costs	Research and development costs Research and development costs are expensed as incurred.
Related Parties	Related Parties In accordance with ASC 850 “Related Party Disclosure”, a party is considered to be related to the Company if the party directly or indirectly or through one or more intermediaries, controls, is controlled by, or is under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal with if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests.
Reclassifications	Reclassifications Certain reclassifications have been made to the prior year financial information to conform to the presentation used in the financial statements for the year ended April 30, 2019.
New Accounting Pronouncements	New Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update provides guidance on classification for cash receipts and payments related to eight specific issues. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the provisions of the pronouncement effective March 1, 2018 and it did not result in a material change to the statement of cash flows. In November 2016, the FASB issued ASU No. 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. There was no impact to the financial statements upon adoption of this update effective May 1, 2018. In January 2017, the FASB issued ASU No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company will apply the provisions of the update to potential future acquisitions occurring after the effective date. In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation, Improvements to Nonemployee Share-Based Payment Accounting. ASU No. 2018-07 aligns accounting for share-based payment transactions for acquiring goods and services from nonemployees with transaction with employees. The update is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02 Leases (Subtopic 842), which will require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by most leases. The update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The ASU will be effective for the Company in the first quarter of fiscal year 2020. We are currently evaluating the impact of the guidance on the Company’s consolidated financial statements. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.
