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 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, a company existing under the laws of the province of British Columbia, Canada, and BridgePort, incorporated under the laws of the state of Delaware. The results of NewHeights (which subsequently was amalgamated with another subsidiary to become CounterPath Technologies) are included from August 2, 2007, the date of acquisition. The results of FirstHand (which subsequently was amalgamated with CounterPath Technologies) and BridgePort are included from February 1, 2008, the date of acquisition. 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 accounting principles generally accepted 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, 2013 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, 2013 annual audited consolidated financial statements.
			Operating results for the six months ended October 31, 2013 are not necessarily indicative of the results that can be expected for the year ending April 30, 2014.
		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 provisions of the new disclosure requirements are effective as of the beginning of the year ended April 30, 2015. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.
			In July 2012, FASB issued ASU 2012-02, Intan gibles – Goodwill and Other (Topic 350), Testing Indefinite Lived Intangible Assets For Impairments , that permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform a quantitative impairment test. An entity would continue to calculate the fair value of an indefinite-lived intangible asset if the asset fails the qualitative assessment, while no further analysis would be required if it passes. The provisions of the new guidance were effective as of the beginning of the year ended April 30, 2014. The Company has adopted this standard and it did not materially impact the consolidated financial statements.
			In February 2013, FASB issued ASU 2013-02, C omprehensive Income (Topic 220), Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income , that requires an entity to disclose information showing the effect of items reclassified from accumulated other comprehensive income on the line items of net income. The provisions of this new guidance are effective prospectively as of the beginning of the year ended April 30, 2014. The adoption of the standard requires the Company to declare the nature of changes in other comprehensive income that will have an impact on net income or loss in the future. The Company has accumulated other comprehensive income relating to the translation of its subsidiary’s financial information into the presentation currency of the Company’s financial statements, which would reverse through net income or loss should the underlying assets and liabilities be disposed of.
		d)	Derivative Instruments
			The Company accounts for derivative instruments, consisting of foreign currency forward contracts, pursuant to the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 161, Disclosures about Derivative Instruments and Hedging Activities — an amendment of FASB Statement No. 133 (“SFAS 161”), effective at the beginning of the first quarter of fiscal year 2010. SFAS 161 was incorporated into Accounting Standards Codification (“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. The Company did not enter into any foreign currency derivatives designed as cash flow hedges in the six months ended October 31, 2013 (2012 - none).
			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 it 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 Company’s Audited Consolidated Financial Statements for the year ended April 30, 2013). The Company did not enter any foreign currency derivatives designated as cash flow hedges in the six months ended October 31, 2013 (2012 - none).
		e)	Goodwill and Intangible Assets
			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 in connection with the acquisition of NewHeights on August 2, 2007 and FirstHand on February 1, 2008. Translated to U.S. dollars using the period end rate, the goodwill balance at October 31, 2013 was $6,407,248 (CDN$6,704,947) (April 30, 2013 - $6,607,725) and $1,990,910 (CDN$2,083,414) (April 30, 2013 - $2,053,205), respectively. Management will perform its annual impairment test in its fiscal fourth quarter. No impairment charges were recorded for the six months periods ended October 31, 2013 and 2012.
			The Company recognizes impairment when the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset. Impairment losses, if any, are measured as the excess of the carrying amount of the asset over its estimated fair value.
			Intangible assets include the intangibles purchased in connection with the acquisition of NewHeights on August 2, 2007, and FirstHand and BridgePort on February 1, 2008.
			The intangible assets of NewHeights are reported at acquisition cost and include amounts initially allocated to acquired technologies of $3,454,839 (CDN$3,678,100) and customer asset of $2,283,908 (CDN$2,431,500). The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset.
	The intangible assets of FirstHand are reported at acquisition cost and include amounts initially allocated to acquired technologies of $2,804,700 (CDN$2,804,700) and customer asset of $587,000 (CDN$587,000). The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset.
	The intangible assets of BridgePort are being carried and reported at acquisition cost and include amounts initially allocated to acquired technologies of $476,703 and customer asset of $43,594. The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset. All the intangible assets were fully amortized as at April 30, 2013.
		f)	Accounts receivable and allowance for doubtful accounts
	Accounts receivable are presented net of an allowance for doubtful accounts.
				October 31,			April 30,
				2013			2013
		Balance of allowance for doubtful accounts, beginning of period	$	456,051		$	334,294
		Bad debt provision		288,158			265,970
		Write-off of receivables		(413,304	)		(144,213	)
		Balance of allowance for doubtful accounts, end of period	$	330,905		$	456,051
		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.

	Note 4	Derivative Financial Instruments and Risk Management
		In the normal course of business, the Company is exposed to fluctuations in interest rates and 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
		The Company accounts for derivative instruments, consisting of foreign currency forward contracts, pursuant to the provisions of SFAS 161, effective at the beginning of the first quarter of fiscal year 2010. SFAS 161 was incorporated into ASC 815 which requires the Company to measure derivative instruments at fair value and record them in our 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.
		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 six months ended October 31, 2013 is the Canadian dollar. The Company is primarily exposed to a strengthening Canadian dollar as the Company’s operating expenses are primarily denominated in Canadian dollars while revenues are primarily denominated in U.S. 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. These instruments generally have a maturity of less than one year. For these derivatives, the company reports the after-tax gain or loss from the effective portion of the hedge as a component of accumulated other comprehensive income (loss) in stockholders’ equity and reclassifies it into earnings in the same period in which the hedged transaction affects earnings, and within the same line item on the consolidated statements of operations as the impact of the hedged transaction.
		The Company also routinely enters into foreign currency forward contracts, not designated as hedging instruments, to protect the Company from fluctuations in exchange rates. As of October 31, 2013, the Company had $4,000,000 of notional value foreign currency forward contracts maturing through February 28, 2014. Notional amounts do not quantify risk or represent assets or liabilities of the Company, but are used in the calculation of cash settlements under the contracts. The fair value marked to market gain (loss) of forward contracts as of October 31, 2013 is ($9,814).
		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 model. The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis.

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 common shares of the Company may be granted to employees, directors and consultants. Stock options entitle the holder to purchase common shares at a subscription 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.
		The maximum number of common shares authorized by the stockholders and reserved for issuance by the Board under the 2010 Stock Option Plan is 6,860,000.
		The Company has elected to use the Black-Scholes option pricing model to determine the fair value of stock options granted. In accordance with ASC 718, Compensation – Stock Compensation (“ASC 718 ”), for employees, the compensation expense is amortized on a straight-line basis over the requisite service period which approximates the vesting period. Compensation expense for stock options granted to non-employees is amortized over the vesting period or, if none exists, over the service period. Compensation associated with unvested options granted to non-employees is remeasured on each balance sheet date using the Black-Scholes option pricing model.
		The expected volatility of options granted has been determined using the method described under ASC 718 using the historical stock price. The expected term of options granted to employees in the current fiscal period has been determined utilizing the “simplified” method as prescribed by ASC 718.
		For non-employees, based on the Company’s history, the expected term of the options approximates the full term of the options. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options.
		The Company has not paid and does not anticipate paying dividends on its common stock; therefore, the expected dividend yield is assumed to be zero. In addition, ASC 718 requires companies to utilize an estimated forfeiture rate when calculating the expense for the period, whereas prior to the adoption of ASC 718 the Company recorded forfeitures based on actual forfeitures and recorded a compensation expense recovery in the period when the awards were forfeited. As a result, based on the Company’s experience, the Company applied an estimated forfeiture rate of 15% for the six month period ended October 31, 2013 and 2012 in determining the expense recorded in the accompanying consolidated statement of operations.
		The weighted-average fair value of options granted during the six months ended October 31, 2013 was $0.89 (2012 - $2.90). The weighted-average assumptions utilized to determine such values are presented in the following table:
				Six Months Ended

Warrants
On May 17, 2012 and July 25, 2012, holders of warrants issued under a brokered private placement exercised 50,000 warrants and 7,000 warrants respectively, at the original exercise price of $2.25 per common share. On October 25, 2012 and November 27, 2012, holders of warrants issued under a brokered private placement, exercised 110,103 and 110,103 warrants respectively, at the original exercise price of $1.75 per common share.
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. The fair value of the derivative instruments are revalued at the end of each reporting period, and the change in fair value of the derivative instruments are recorded as a gain or loss in the Company’s consolidated statements of operations.
The warrant liability is accounted for at its fair value as follows:
			October 31,			April 30,
			2013			2013
	Opening balance at the beginning of the period/year	$	93,057		$	2,026,944

	Change in fair value of warrant liability		(93,057	)		(1,753,368	)
	Fair value of warrants exercised during the period/year		–			(180,519	)
	Fair value of warrant liability at end of period/year	$	–		$	93,057
	The Company uses 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-Oct-13		30-Apr-13		14-Jun-11
	Risk-free interest rate	–		0.11%		1.60%
	Expected volatility	–		70%		70%
	Expected term	–		0.12 years		1.5 years to 2 years
	Dividend yield	–		0%		0%
The warrant liability is revalued at the end of each reporting period with the change in the fair value of the derivative instruments recorded as a gain or loss in the Company’s consolidated statement of operations. The fair value of the warrants will continue to be classified as a liability until such time as they are exercised, expire or there is an amendment to the respective agreements that renders these financial instruments to be no longer classified as a liability. 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.
At the time of the private placement offering, the Company allocated the proceeds to each of the common shares and the one-half of one common share purchase warrants. Because the warrants were classified as a liability and are subsequently marked to fair value through earnings in each reporting period, the Company allocated the proceeds of $1,311,141 to the warrants at inception with the residual proceeds of $3,773,946 allocated to common stock.
The following table summarizes information regarding the warrants outstanding as of October 31, 2013:

	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 common shares of the Company 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 six months ended October 31, 2013, the Company matched $26,106 (April 30, 2013 - $56,250) in shares purchased by employees under the ESPP.
	A total of 700,000 shares have been reserved for issuance under the ESPP. As of October 31, 2013, a total of 556,401 shares were available for issuance under the ESPP. During the six months ended October 31, 2013, 48,222 shares (April 30, 2013 – 61,622) were sold, issued, or purchased by employees on the open market under the ESPP.
	Normal Course Issuer Bid Plan
	Pursuant to a normal course issuer bid commencing on August 20, 2012 and expiring on March 19, 2013, the Company was authorized to purchase up to 1,995,414 of its common shares and on March 19, 2013 (expiring March 18, 2014) the Company was authorized to purchase 2,462,365 of its common shares through the facilities of the Toronto Stock Exchange (the “TSX”) and other Canadian marketplaces. Between August 20, 2012 and March 18, 2013, the Company repurchased 72,292 common shares at an average price of $1.99 (CDN$1.98) for a total of $143,861 and during the period from March 19, 2013 to October 31, 2013, the Company repurchased 154,836 common shares at an average price of $1.77 (CDN$1.83) for a total of $274,060. As of October 31, 2013 a total of 202,308 common shares have been cancelled and the remaining 24,820 repurchased shares are in the process of being cancelled.
	Deferred Share Unit Plan
	Under the terms of the Deferred Share Unit Plan (the “DSUP”), each deferred share unit (“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 common shares of the Company outstanding at the time of reservation. A DSU granted to a participant who is a director of the Board 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 Company’s common shares on the date of grant, is recorded as compensation expense over the vesting period.
	A total of 2,500,000 common shares have been reserved for issuance under the DSUP. During the six months ended October 31, 2013, 191,066 (2012 - 133,443) DSUs were issued under the DSUP, of which 75,417 were granted to officers or employees and 115,649 were granted to non-employee directors. As of October 31, 2013, a total of 587,427 common shares were available for issuance under the DSUP.
	The following table summarizes the Company’s outstanding DSU awards as of October 31, 2013, and changes during the period then ended:

Summary_of_Significant_Account

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Oct. 31, 2013
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, a company existing under the laws of the province of British Columbia, Canada, and BridgePort, incorporated under the laws of the state of Delaware. The results of NewHeights (which subsequently was amalgamated with another subsidiary to become CounterPath Technologies) are included from August 2, 2007, the date of acquisition. The results of FirstHand (which subsequently was amalgamated with CounterPath Technologies) and BridgePort are included from February 1, 2008, the date of acquisition. 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 accounting principles generally accepted 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, 2013 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, 2013 annual audited consolidated financial statements.
			Operating results for the six months ended October 31, 2013 are not necessarily indicative of the results that can be expected for the year ending April 30, 2014.
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 provisions of the new disclosure requirements are effective as of the beginning of the year ended April 30, 2015. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.
			In July 2012, FASB issued ASU 2012-02, Intan gibles – Goodwill and Other (Topic 350), Testing Indefinite Lived Intangible Assets For Impairments , that permits an entity to first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform a quantitative impairment test. An entity would continue to calculate the fair value of an indefinite-lived intangible asset if the asset fails the qualitative assessment, while no further analysis would be required if it passes. The provisions of the new guidance were effective as of the beginning of the year ended April 30, 2014. The Company has adopted this standard and it did not materially impact the consolidated financial statements.
			In February 2013, FASB issued ASU 2013-02, C omprehensive Income (Topic 220), Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income , that requires an entity to disclose information showing the effect of items reclassified from accumulated other comprehensive income on the line items of net income. The provisions of this new guidance are effective prospectively as of the beginning of the year ended April 30, 2014. The adoption of the standard requires the Company to declare the nature of changes in other comprehensive income that will have an impact on net income or loss in the future. The Company has accumulated other comprehensive income relating to the translation of its subsidiary’s financial information into the presentation currency of the Company’s financial statements, which would reverse through net income or loss should the underlying assets and liabilities be disposed of.
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 Statement of Financial Accounting Standards (“SFAS”) No. 161, Disclosures about Derivative Instruments and Hedging Activities — an amendment of FASB Statement No. 133 (“SFAS 161”), effective at the beginning of the first quarter of fiscal year 2010. SFAS 161 was incorporated into Accounting Standards Codification (“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. The Company did not enter into any foreign currency derivatives designed as cash flow hedges in the six months ended October 31, 2013 (2012 - none).
			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 it 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 Company’s Audited Consolidated Financial Statements for the year ended April 30, 2013). The Company did not enter any foreign currency derivatives designated as cash flow hedges in the six months ended October 31, 2013 (2012 - none).
Goodwill and Intangible Assets [Policy Text Block]	'
		e)	Goodwill and Intangible Assets
			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 in connection with the acquisition of NewHeights on August 2, 2007 and FirstHand on February 1, 2008. Translated to U.S. dollars using the period end rate, the goodwill balance at October 31, 2013 was $6,407,248 (CDN$6,704,947) (April 30, 2013 - $6,607,725) and $1,990,910 (CDN$2,083,414) (April 30, 2013 - $2,053,205), respectively. Management will perform its annual impairment test in its fiscal fourth quarter. No impairment charges were recorded for the six months periods ended October 31, 2013 and 2012.
			The Company recognizes impairment when the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset. Impairment losses, if any, are measured as the excess of the carrying amount of the asset over its estimated fair value.
			Intangible assets include the intangibles purchased in connection with the acquisition of NewHeights on August 2, 2007, and FirstHand and BridgePort on February 1, 2008.
			The intangible assets of NewHeights are reported at acquisition cost and include amounts initially allocated to acquired technologies of $3,454,839 (CDN$3,678,100) and customer asset of $2,283,908 (CDN$2,431,500). The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset.
	The intangible assets of FirstHand are reported at acquisition cost and include amounts initially allocated to acquired technologies of $2,804,700 (CDN$2,804,700) and customer asset of $587,000 (CDN$587,000). The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset.
	The intangible assets of BridgePort are being carried and reported at acquisition cost and include amounts initially allocated to acquired technologies of $476,703 and customer asset of $43,594. The acquired technologies are amortized based on their estimated useful life of four years and the customer asset is amortized on the basis of management’s estimate of the future cash flows from this asset over approximately five years, which is management’s estimate of the useful life of the customer asset. All the intangible assets were fully amortized as at April 30, 2013.

		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.
