Significant Accounting Policies [Text Block]	Note 2	Significant Accounting Policies
	These interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and are stated in U.S. dollars except where otherwise disclosed. Because a precise determination of many assets and liabilities is dependent upon future events, the preparation of financial statements for the period necessarily involves the use of estimates, which have been made using careful judgment. Actual results may vary from these estimates.
	These interim 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 and commitments in the normal course of business.
		a)	Basis of Presentation
			These interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, CounterPath Technologies Inc. (“CounterPath Technologies”), a company existing under the laws of the province of British Columbia, Canada, and BridgePort Networks, Inc. (“BridgePort”), incorporated under the laws of the state of Delaware. All inter- company transactions and balances have been eliminated.
		b)	Interim Reporting
			The information presented in the accompanying interim consolidated financial statements is without audit pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading.
			These statements reflect all adjustments, which are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented in accordance with generally accepted accounting principles in the United States of America. Except where noted, these interim financial statements follow the same accounting policies and methods of their application as the Company’s April 30, 2014 annual audited consolidated financial statements. All adjustments are of a normal recurring nature. It is suggested that these interim financial statements be read in conjunction with the Company’s April 30, 2014 annual audited consolidated financial statements.
			Operating results for the nine months ended January 31, 2015 are not necessarily indicative of the results that can be expected for the year ending April 30, 2015.
		c)	New Accounting Pronouncements
			In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2011-11, Balance Sheet (Topic 210), Disclosure About Offsetting Assets and Liabilities , that included new disclosure requirements that are intended to enhance current disclosures on offsetting financial assets and liabilities. The new disclosures require an entity to disclose both gross and net information about derivative instruments accounted for in accordance with the guidance on derivatives and hedging that are eligible for offset on the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. The Company adopted this standard as of May 1, 2014 and it did not materially impact the consolidated financial statements.
			In May 2014, FASB issued ASU 2014-09, Revenue From Contracts With Customers (“Topic 606”). Topic 606 removes inconsistencies and weaknesses in revenue requirements, provides a more robust framework for addressing revenue issues, improves comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets, provides more useful information to users of financial statements through improved disclosure requirements and simplifies the preparation of financial statements by reducing the number of requirements to which an entity must refer. The guidance in this update supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. Topic 606 is effective for public entities with reporting periods beginning after December 15, 2016. Early adoption is not permitted. The Company has not yet evaluated the impact of the adoption of this new standard.
		d)	Derivative Instruments
			The Company accounts for derivative instruments, consisting of foreign currency forward contracts, pursuant to the provisions of ASC 815, Derivatives and Hedging (“ASC 815”). ASC 815 requires the Company to measure derivative instruments at fair value and record them in the balance sheet as either an asset or liability and expands financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, results of operations and cash flows. The Company does not use derivative instruments for trading purposes. ASC 815 also requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Following the guidance in ASC 815-40-15, the Company recorded the warrants issued as derivative instruments due to their exercise price being denominated in a currency other than the Company’s U.S. dollar functional currency initially at fair value. Subsequent changes in the fair value of the derivative instruments are recorded as a gain or loss in the Company’s consolidated statements of operations.
			The Company also routinely enters into foreign currency forward contracts, not designated as hedging instruments, to protect the Company from fluctuations in exchange rates. Gains or losses arising out of marked to market fair value valuation of forward contracts, not designated as hedges, and are recognized in net income.
			The Company records foreign currency forward contracts on its Consolidated Balance Sheets as derivative instruments assets or liabilities depending on whether the net fair value of such contracts is a net asset or net liability, respectively (see Note 4 “Derivative Financial Instruments and Risk Management,” of the Notes to the Consolidated Financial Statements). The Company did not enter any foreign currency derivatives designated as cash flow hedges in the three and nine months ended January 31, 2015.
		e)	Goodwill
			Goodwill represents the excess purchase price over the estimated fair value of net assets acquired as of the acquisition date. ASC Topic 350 (“ASC 350”) requires goodwill to be tested for impairment annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company's business enterprise below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. Recoverability of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit, which is measured based upon, among other factors, market multiples for comparable companies as well as a discounted cash flow analysis.
			Management has determined that the Company currently has a single reporting unit which is CounterPath Corporation. If the recorded value of the assets, including goodwill, and liabilities (“net book value”) of the reporting unit exceeds its fair value, an impairment loss may be required.
			Goodwill of $6,339,717 (CDN$6,704,947) and $2,083,960 (CDN$2,083,752) was initially recorded as the Company was deemed to be the acquirer of NewHeights Software Corporation (“NewHeights”) on August 2, 2007 and FirstHand Technologies Inc. (“FirstHand”) on February 1, 2008, respectively. Translated to U.S. dollars using the period end rate, the goodwill balance at January 31, 2015 was $5,296,167 (CDN$6,704,947) (April 30, 2014 - $6,117,653) in respect of NewHeights and $1,645,666 (CDN$2,083,414) (April 30, 2014 - $1,900,925) in respect of FirstHand. Management will perform its annual impairment test in its fiscal fourth quarter. No impairment charges were recorded for the nine months ended January 31, 2015 and 2014.
		f)	Accounts Receivable and Allowance for Doubtful Accounts
			Accounts receivable are presented net of an allowance for doubtful accounts.
				January 31,			April 30,
				2015			2014
		Balance of allowance for doubtful accounts, beginning of
		period/year	$	240,681		$	456,051
		Bad debt provision		544,111			415,448
		Write-off of receivables		(444,564	)		(630,818	)
		Balance of allowance for doubtful accounts, end of period/year	$	340,228		$	240,681
	The Company determines the allowance for doubtful accounts by considering a number of factors, including the length of time the accounts receivable are beyond the contractual payment terms, previous loss history, and the customer’s current ability to pay its obligation. When the Company becomes aware of a specific customer’s inability to meet its financial obligations to the Company, the Company records a charge to the allowance to reduce the customer’s related accounts.
		g)	Basic and Diluted Loss per Share
			The Company computes net loss per share in accordance with ASC Topics 260 and ASC 260-10. ASC 260 requires presentation of both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is computed by dividing net loss available to common shareholders by the weighted average number of common shares outstanding during the year. Diluted EPS gives effect to all dilutive potential common shares outstanding during the year including stock options and warrants using the treasury stock method. In computing diluted EPS, the average stock price for the year is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. For the nine months ended January 31, 2015 and January 31, 2014, common share equivalents, consisting of common shares issuable, on exercise of options, warrants and deferred share units (“DSUs”) of 5,759,630 and 4,834,230, respectively, were not included in the computation of diluted EPS because the effect was anti- dilutive.

Derivative Financial Instruments and Risk Management	9 Months Ended
	Jan. 31, 2015
Derivative Financial Instruments and Risk Management [Text Block]	Note 4	Derivative Financial Instruments and Risk Management
	In the normal course of business, the Company is exposed to fluctuations in the exchange rates associated with foreign currencies. The Company’s primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk.
	Foreign Currency Exchange Rate Risk
	A majority of the Company’s revenue activities are transacted in U.S. dollars. However, the Company is exposed to foreign currency exchange rate risk inherent in conducting business globally in numerous currencies, of which the most significant to the Company’s operations for the three and nine months ended January 31, 2015 is the Canadian dollar as a majority of the Company’s expenses are in Canadian dollars. The Company’s foreign currency risk management program includes foreign currency derivatives with cash flow hedge accounting designation that utilizes foreign currency forward contracts to hedge exposures to the variability in the U.S. dollar equivalent of anticipated non-U.S. dollar-denominated cash flows. During the three and nine months ended January 31, 2015, the Company did not enter into any cash flow hedges.
	The Company also routinely enters into foreign currency forward contracts, not designated as hedging instruments, to protect it from fluctuations in exchange rates. During the three and nine months ended January 31, 2015, the Company did not enter into any foreign currency forward contracts. During the three and nine months ended January 31, 2014, the Company had $1,000,000 of notional value foreign currency forward contracts that matured through February 28, 2014. The fair marked to market gain or (loss) of the forward contracts for the three and nine month period ended January 31, 2014 was ($61,294) and $12,119.
	Fair Value Measurement
	When available, the Company uses quoted market prices to determine fair value, and classifies such measurements within Level 1. In some cases where market prices are not available, the Company makes use of observable market–based inputs to calculate fair value, in which case the measurements are classified within Level 2. If quoted or observable market prices are not available, fair value is based upon internally developed models that use, where possible, current market–based parameters such as interest rates, yield curves and currency rates. These measurements are classified within Level 3.
	Fair value measurements are classified according to the lowest level input or value–driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable.
	Fair value measurement includes the consideration of non–performance risk. Non–performance risk refers to the risk that an obligation (either by a counterparty or the Company) will not be fulfilled. For financial assets traded in an active market (Level 1), the non–performance risk is included in the market price. For certain other financial assets and liabilities (Level 2 and 3), the Company’s fair value calculations have been adjusted accordingly.
	The fair value of the derivative instrument is primarily based on the standard industry accepted Binomial Method (Note 5). The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis as of January 31, 2015 and April 30, 2014.

Common Stock	9 Months Ended

Common Stock [Text Block]	Note 5	Common Stock
	Stock Options
	The Company has a stock option plan (the “2010 Stock Option Plan”) under which options to purchase shares of the Company’s common stock may be granted to employees, directors and consultants. Stock options entitle the holder to purchase shares of the Company’s common stock at an exercise price determined by the board of directors (the “Board”) of the Company at the time of the grant. The options generally vest in the amount of 12.5% on the date which is six months from the date of grant and then beginning in the seventh month at 1/42 per month for 42 months, at which time the options are fully vested.
	On September 9, 2014, the maximum number of shares of common stock authorized by the stock holders and reserved for issuance by the Board under the 2010 Stock Option Plan was increased from 6,860,000 to 7,860,000.
	The Company uses the Black-Scholes option pricing model to determine the fair value of stock options granted. The Company applied an estimated forfeiture rate of 15% for the nine months ended January 31, 2015 and 2014 in determining the expense recorded in the accompanying consolidated statement of operations.
	For the majority of the stock options granted, the number of shares issued on the date the stock options are exercised is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of its employees. Although these withheld shares are not issued or considered common stock repurchases under our authorized plan they are treated as common stock repurchases in our consolidated financial statements, as they reduce the number of shares that would have been issued upon vesting.
	The weighted-average fair value of options granted during the three and nine months ended January 31, 2015 and 2014 was $0.78 and $1.12, respectively, and $0.63 and $0.79, respectively. The weighted-average assumptions utilized to determine such values are presented in the following table:

Warrants
On June 14, 2011, the Company issued an aggregate of 3,145,800 units under a brokered private placement for aggregate gross proceeds of $5,636,170 (CDN$5,505,150) at a price of $1.79 (CDN$1.75) per unit, with each unit consisting of one share of the Company’s common stock and one-half of one common share purchase warrant, with each whole warrant entitling the holder to purchase one additional share of the Company’s common stock at an exercise price of CDN$2.25 per share until June 14, 2013. In connection with the offering, the Company issued an aggregate of 220,206 broker warrants, with each broker warrant entitling the holder thereof to purchase one share of the Company’s common stock at an exercise price of CDN$1.75 per share until December 14, 2012.
On June 19, 2012, the Company issued an aggregate of 1,465,000 units under a non-brokered private placement for aggregate gross proceeds of CDN$3,662,500 ($3,579,335) at a price of CDN$2.50 ($2.44) per unit, with each unit consisting of one share of the Company’s common stock and one-half of one common share purchase warrant, with each whole warrant entitling the holder to purchase one additional share of the Company’s common stock at an exercise price of $3.25 per share until June 19, 2014. The 732,500 warrants issued expired unexercised on June 20, 2014.
Following the guidance in ASC 815-40-15, the Company recorded the warrants issued on June 19, 2012 as derivative instruments due to their exercise price being denominated in a currency other than the Company’s U.S. dollar functional currency. The fair value of the derivative instruments was revalued at the end of each reporting period, and the change in fair value of the derivative instruments was recorded as a gain or loss in the Company’s consolidated statements of operations.
The warrant liability was accounted for at its fair value as follows:
			January 31,			April 30,
			2015			2014
	Opening balance at the beginning of the period/year	$	–		$	93,057
	Fair value of warrant liability, at issuance		–			–
	Change in fair value of warrant liability		–			(93,057	)
	Fair value of warrants exercised during the period/year		–			–
	Fair value of warrant liability at end of period/year	$	–		$	–
The Company used the Binomial Method to estimate the fair value of the warrants with the following assumptions:
									As at the date of
			As at			As at			issuance
			31-Jan-15			30-Apr-14			14-Jun-11
	Risk-free interest rate		–			–			1.60%
	Expected volatility		–			–			70%
	Expected term		–			–			1.5 years to 2 years
	Dividend yield		–			–			0%
The fair value of the warrants were classified as a derivative liability until such time as they were exercised or expired. The balance of unexercised warrants expired on June 14, 2013, and the balance in the liability account of $93,057 has been recorded as a gain in the Company’s consolidated statement of operations for the year ended April 30, 2014.

Employee Stock Purchase Plan
Under the terms of the Employee Stock Purchase Plan (the “ESPP”) all regular salaried (non-probationary) employees can purchase up to 6% of their base salary in shares of the Company’s common stock at market price. The Company will match 50% of the shares purchased by issuing or purchasing in the market up to 3% of the respective employee’s base salary in shares. During the nine months ended January 31, 2015, the Company matched $43,516 (2014 - $38,333) in shares purchased by employees under the ESPP. During the nine months ended January 31, 2015, 136,749 shares (2014 – 75,438) were purchased on the open market under the ESPP.
A total of 700,000 shares have been reserved for issuance under the ESPP. As of January 31, 2015, a total of 556,401 shares were available for issuance under the ESPP.
Normal Course Issuer Bid Plan
Pursuant to a normal course issuer bid (“NCIB”) commencing on March 19, 2013 (expiring March 18, 2014), the Company was authorized to purchase 2,462,365 of its shares of common stock through the facilities of the Toronto Stock Exchange (the “TSX”) and other Canadian or US marketplaces. The NCIB was renewed on March 19, 2014 (expiring March 18, 2015) and the Company was authorized to purchase 2,458,153 of shares of common stock. During the period from March 19, 2013 to March 18, 2014, the Company repurchased 180,870 shares at an average price of $1.53 (CDN$1.61) for a total of $276,731 and during the period from March 19, 2014 to January 31, 2015, the Company repurchased 346,326 shares at an average price of $0.95 (CDN$1.06) for a total of $327,525. As of January 31, 2015, a total of 552,240 shares have been cancelled and the remaining 77,044 repurchased shares are in the process of being cancelled since the NCIB was initiated.
Deferred Share Unit Plan
Under the terms of the Deferred Share Unit Plan (the “DSUP”), each DSU is equivalent to one common share. The maximum number of common shares that may be reserved for issuance to any one participant pursuant to DSUs granted under the DSUP and any share compensation arrangement is 5% of the number of shares outstanding at the time of reservation. A DSU granted to a participant who is a director of the Company shall vest immediately on the award date. A DSU granted to a participant other than a director will generally vest as to one-third (1/3) of the number of DSUs granted on the first, second and third anniversaries of the award date. Fair value of the DSUs, which is based on the closing price of the shares of the Company’s common stock on the date of grant, is recorded as compensation expense over the vesting period.
On September 9, 2014, the shares reserved for issuance under the DSUP plan was increased from 2,500,000 to 3,000,000. During the nine months ended January 31, 2015, 326,613 (2014 - 191,066) DSUs were issued under the DSUP, of which 145,161 were granted to officers or employees and 181,452 were granted to non-employee directors. As of January 31, 2015, a total of 760,814 shares were available for issuance under the DSUP.

Basis of Presentation [Policy Text Block]		a)	Basis of Presentation
			These interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, CounterPath Technologies Inc. (“CounterPath Technologies”), a company existing under the laws of the province of British Columbia, Canada, and BridgePort Networks, Inc. (“BridgePort”), incorporated under the laws of the state of Delaware. All inter- company transactions and balances have been eliminated.
Interim Reporting [Policy Text Block]		b)	Interim Reporting
			The information presented in the accompanying interim consolidated financial statements is without audit pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading.
			These statements reflect all adjustments, which are, in the opinion of management, necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented in accordance with generally accepted accounting principles in the United States of America. Except where noted, these interim financial statements follow the same accounting policies and methods of their application as the Company’s April 30, 2014 annual audited consolidated financial statements. All adjustments are of a normal recurring nature. It is suggested that these interim financial statements be read in conjunction with the Company’s April 30, 2014 annual audited consolidated financial statements.
			Operating results for the nine months ended January 31, 2015 are not necessarily indicative of the results that can be expected for the year ending April 30, 2015.
New Accounting Pronouncements [Policy Text Block]		c)	New Accounting Pronouncements
			In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2011-11, Balance Sheet (Topic 210), Disclosure About Offsetting Assets and Liabilities , that included new disclosure requirements that are intended to enhance current disclosures on offsetting financial assets and liabilities. The new disclosures require an entity to disclose both gross and net information about derivative instruments accounted for in accordance with the guidance on derivatives and hedging that are eligible for offset on the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. The Company adopted this standard as of May 1, 2014 and it did not materially impact the consolidated financial statements.
			In May 2014, FASB issued ASU 2014-09, Revenue From Contracts With Customers (“Topic 606”). Topic 606 removes inconsistencies and weaknesses in revenue requirements, provides a more robust framework for addressing revenue issues, improves comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets, provides more useful information to users of financial statements through improved disclosure requirements and simplifies the preparation of financial statements by reducing the number of requirements to which an entity must refer. The guidance in this update supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. Topic 606 is effective for public entities with reporting periods beginning after December 15, 2016. Early adoption is not permitted. The Company has not yet evaluated the impact of the adoption of this new standard.
Derivative Instruments [Policy Text Block]		d)	Derivative Instruments
			The Company accounts for derivative instruments, consisting of foreign currency forward contracts, pursuant to the provisions of ASC 815, Derivatives and Hedging (“ASC 815”). ASC 815 requires the Company to measure derivative instruments at fair value and record them in the balance sheet as either an asset or liability and expands financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position, results of operations and cash flows. The Company does not use derivative instruments for trading purposes. ASC 815 also requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. Following the guidance in ASC 815-40-15, the Company recorded the warrants issued as derivative instruments due to their exercise price being denominated in a currency other than the Company’s U.S. dollar functional currency initially at fair value. Subsequent changes in the fair value of the derivative instruments are recorded as a gain or loss in the Company’s consolidated statements of operations.
			The Company also routinely enters into foreign currency forward contracts, not designated as hedging instruments, to protect the Company from fluctuations in exchange rates. Gains or losses arising out of marked to market fair value valuation of forward contracts, not designated as hedges, and are recognized in net income.
			The Company records foreign currency forward contracts on its Consolidated Balance Sheets as derivative instruments assets or liabilities depending on whether the net fair value of such contracts is a net asset or net liability, respectively (see Note 4 “Derivative Financial Instruments and Risk Management,” of the Notes to the Consolidated Financial Statements). The Company did not enter any foreign currency derivatives designated as cash flow hedges in the three and nine months ended January 31, 2015.
Goodwill [Policy Text Block]		e)	Goodwill
			Goodwill represents the excess purchase price over the estimated fair value of net assets acquired as of the acquisition date. ASC Topic 350 (“ASC 350”) requires goodwill to be tested for impairment annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the Company's business enterprise below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit. Recoverability of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit, which is measured based upon, among other factors, market multiples for comparable companies as well as a discounted cash flow analysis.
			Management has determined that the Company currently has a single reporting unit which is CounterPath Corporation. If the recorded value of the assets, including goodwill, and liabilities (“net book value”) of the reporting unit exceeds its fair value, an impairment loss may be required.
			Goodwill of $6,339,717 (CDN$6,704,947) and $2,083,960 (CDN$2,083,752) was initially recorded as the Company was deemed to be the acquirer of NewHeights Software Corporation (“NewHeights”) on August 2, 2007 and FirstHand Technologies Inc. (“FirstHand”) on February 1, 2008, respectively. Translated to U.S. dollars using the period end rate, the goodwill balance at January 31, 2015 was $5,296,167 (CDN$6,704,947) (April 30, 2014 - $6,117,653) in respect of NewHeights and $1,645,666 (CDN$2,083,414) (April 30, 2014 - $1,900,925) in respect of FirstHand. Management will perform its annual impairment test in its fiscal fourth quarter. No impairment charges were recorded for the nine months ended January 31, 2015 and 2014.
Accounts Receivable and Allowance for Doubtful Accounts [Policy Text Block]		f)	Accounts Receivable and Allowance for Doubtful Accounts
			Accounts receivable are presented net of an allowance for doubtful accounts.
				January 31,			April 30,
				2015			2014
		Balance of allowance for doubtful accounts, beginning of
		period/year	$	240,681		$	456,051
		Bad debt provision		544,111			415,448
		Write-off of receivables		(444,564	)		(630,818	)
		Balance of allowance for doubtful accounts, end of period/year	$	340,228		$	240,681
	The Company determines the allowance for doubtful accounts by considering a number of factors, including the length of time the accounts receivable are beyond the contractual payment terms, previous loss history, and the customer’s current ability to pay its obligation. When the Company becomes aware of a specific customer’s inability to meet its financial obligations to the Company, the Company records a charge to the allowance to reduce the customer’s related accounts.
Basic and Diluted Loss per Share [Policy Text Block]		g)	Basic and Diluted Loss per Share
			The Company computes net loss per share in accordance with ASC Topics 260 and ASC 260-10. ASC 260 requires presentation of both basic and diluted earnings per share (“EPS”) on the face of the consolidated statement of operations. Basic EPS is computed by dividing net loss available to common shareholders by the weighted average number of common shares outstanding during the year. Diluted EPS gives effect to all dilutive potential common shares outstanding during the year including stock options and warrants using the treasury stock method. In computing diluted EPS, the average stock price for the year is used in determining the number of shares assumed to be purchased from the exercise of stock options or warrants. For the nine months ended January 31, 2015 and January 31, 2014, common share equivalents, consisting of common shares issuable, on exercise of options, warrants and deferred share units (“DSUs”) of 5,759,630 and 4,834,230, respectively, were not included in the computation of diluted EPS because the effect was anti- dilutive.
