| Nature of the business |
Xenon Pharmaceuticals Inc. (the “Company”), incorporated in 1996 under the British Columbia Business Corporations Act and continued federally in 2000 under the Canada Business Corporation Act, is a clinical stage biopharmaceutical company focused on developing innovative therapeutics to improve the lives of patients with neurological disorders. Building upon its extensive knowledge of human genetics and diseases caused by mutations in ion channels, known as channelopathies, the Company is advancing a novel product pipeline of neurology-focused therapies to address areas of high unmet medical need, with a focus on epilepsy. The Company has incurred significant operating losses since inception. As of March 31, 2019, the Company had an accumulated deficit of $219,401 and an $11,341 net loss for the three months ended March 31, 2019. Management expects to continue to incur significant expenses in excess of revenue and to incur operating losses for the foreseeable future. To date, the Company has financed its operations primarily through funding received from collaboration and license agreements, private placements of common and preferred shares, public offerings of common shares, debt financing, and government funding. Until such time as the Company can generate substantial product revenue, if ever, management expects to finance the Company’s cash needs through a combination of collaboration agreements, equity and debt financings. The continuation of research and development activities and the future commercialization of its products are dependent on the Company’s ability to successfully raise additional funds when needed. It is not possible to predict either the outcome of future research and development programs or the Company’s ability to continue to fund these programs in the future. |

| Basis of presentation |
These consolidated financial statements are presented in U.S. dollars. The Company has one wholly-owned subsidiary as of March 31, 2019, Xenon Pharmaceuticals USA Inc., which was incorporated in Delaware on December 2, 2016. These unaudited interim consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All intercompany transactions and balances have been eliminated on consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation. The accompanying unaudited interim consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, these consolidated financial statements do not include all of the information and footnotes required for complete consolidated financial statements and should be read in conjunction with the audited consolidated financial statements and notes for the year ended December 31, 2018 and included in the Company’s 2018 Annual Report on Form 10-K filed with the SEC and with the securities commissions in British Columbia, Alberta and Ontario on March 6, 2019. These unaudited interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, which, in the opinion of management, are necessary for a fair presentation of results for the interim periods presented. The results of operations for the three months ended March 31, 2019 and 2018 are not necessarily indicative of results that can be expected for a full year. These unaudited interim consolidated financial statements follow the same significant accounting policies as those described in the notes to the audited consolidated financial statements of the Company included in the Company’s 2018 Annual Report on Form 10-K for the year ended December 31, 2018, with the exception of the policy described in note 3 below. |

Changes in Significant Accounting Policies |

| Accounting Policies [Abstract] | |||
| Changes in significant accounting policies |
The Company adopted the new lease standard (Accounting Standards Codification “ASC” 842), effective January 1, 2019, using the transition method under which previously presented financial statements are not restated and the cumulative effect of adopting the new lease standard on leases existing as of, or entered into after January 1, 2019, is recognized by an adjustment to retained earnings at the effective date. Consequently, comparative periods have been accounted for in accordance with the previous lease standard and the disclosures are in accordance with ASC 840. In addition, the Company elected to apply the package of practical expedients which allows entities not to reassess its previous conclusions about lease identification, lease classification, and initial direct costs. The Company elected not to use hindsight to determine lease terms and to not separate non-lease components from the associated lease component. The new lease standard only impacted the Company’s one operating lease for its premises. Adoption of the new lease standard resulted in recognition of a right-of-use asset of $1,333 and a lease liability of $1,453, as of January 1, 2019. The difference between the right-of-use asset and lease liability relates to the balance of deferred tenant inducements. In addition, a cumulative effect adjustment of $175 was recorded to opening retained earnings. The adoption of the new lease standard did not materially impact the consolidated statement of operations and comprehensive loss or the consolidated statement of cash flows. For additional disclosure and detail, see note 6 below. |

| Earnings Per Share [Abstract] | |||
| Net income (loss) per common and preferred share |
Basic net income (loss) per common share is calculated using the two-class method required for participating securities which includes the convertible preferred shares as a separate class. The preferred shares entitle the holders to participate in dividends and in earnings and losses of the Company on an equivalent basis as common shares. Accordingly, undistributed earnings (losses) are allocated to common shares and participating preferred shares based on the weighted-average shares of each class outstanding during the period. The treasury stock method is used to compute the dilutive effect of the Company’s stock options and warrants. Under this method, the incremental number of common shares used in computing diluted net income (loss) per common share is the difference between the number of common shares assumed issued and purchased using assumed proceeds. The if-converted method is used to compute the dilutive effect of the Company’s convertible preferred shares. Under the if-converted method, dividends on the preferred shares, if applicable, are added back to earnings attributable to common shareholders, and the preferred shares and paid-in kind dividends are assumed to have been converted at the share price applicable at the end of the period. The if-converted method is applied only if the effect is dilutive. For the three months ended March 31, 2019 and 2018, all stock options, warrants and convertible preferred shares were anti-dilutive and were excluded from the diluted weighted average common shares outstanding for the period. |

| Fair Value Disclosures [Abstract] | ||||||||||||
| Fair value of financial instruments |
Certain financial instruments and other items are measured at fair value. To determine the fair value, the Company uses the fair value hierarchy for inputs used to measure fair value of financial assets and liabilities. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels: Level 1 (highest priority), Level 2, and Level 3 (lowest priority).
Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s Level 1 assets include cash and cash equivalents and marketable securities with quoted prices in active markets. The carrying amount of accounts receivables, accounts payable and accrued expenses approximates fair value due to the nature and short-term of those instruments. The Company’s term loan bears interest at a rate that approximates prevailing market rates for instruments with similar characteristics and, accordingly, the carrying value of the loan approximates fair value. |

| Leases |
The Company has one operating lease for research laboratories and office space in Burnaby, British Columbia for a 120-month term from April 1, 2012 to March 31, 2022. Operating lease assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As the Company’s operating lease does not provide an implicit rate, the discount rate used to determine the present value of the lease payments is the collateralized incremental borrowing rate based on the remaining lease term. The operating lease asset excludes lease incentives. The operating lease contains the option to extend or terminate the lease term at the Company’s discretion. Renewal and termination options are included in the lease term when it is reasonably certain that the option will be exercised. Operating lease expense is recognized on a straight-line basis over the lease term. The cost components of our operating lease were as follows for the period ended March 31, 2019:
Future minimum lease payments as of March 31, 2019 were as follows:

| Term Loan |
In August 2018, the Company entered into an Amended and Restated Loan and Security Agreement (the “Amended and Restated Loan Agreement”) with Silicon Valley Bank (the “Bank”), pursuant to which the Bank agreed to extend a term loan to the Company with a principal amount of $15,500. At March 31, 2019, the Company determined the effective interest rate on the Amended and Restated Loan Agreement to be 9.53% (December 31, 2018 – 9.53%). Amortization of the debt discount and accretion of the final payment fee was $125 for the three months ended March 31, 2019 (March 31, 2018 - $72). Interest payments are made monthly. Interest expense was $358 for the three months ended March 31, 2019 (March 31, 2018 - $159). The outstanding loan and unamortized debt discount balances as of March 31, 2019 in accordance with the repayment terms under the Amended and Restated Loan Agreement are as follows:
Scheduled principal payments on outstanding debt as of March 31, 2019, excluding the final payment fee of $1,008, are as follows:
The Amended and Restated Loan Agreement contains customary representations and warranties, events of default (including an event of default upon the occurrence of a material impairment on the Bank’s security interest over the collateral, and a material adverse change of the Company) and affirmative and negative covenants, including, among others, covenants that limit or restrict the Company’s ability to incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into certain transactions with affiliates, engage in any new line of business, pay dividends or make distributions, or repurchase stock, in each case subject to certain exceptions. The Company is in compliance with these covenants at March 31, 2019. At March 31, 2019, the Company has a warrant outstanding to the Bank to purchase 40,000 of the Company’s common shares at a price per share of $9.79. |

In May 2018, the Company entered into an at-the-market equity offering sales agreement with Stifel Nicolaus & Company, Incorporated (“Stifel”) to sell common shares of the Company having aggregate gross proceeds of up to $30,000, from time to time, through an “at-the-market” equity offering program under which Stifel would act as sales agent. The Company had sold 3,440,000 common shares under the sales agreement for proceeds of approximately $29,200, net of commissions paid, but excluding estimated transaction expenses. In July 2018, the Company entered into an at-the-market equity offering sales agreement with Jefferies LLC (“Jefferies”) and Stifel, to sell common shares of the Company having aggregate gross proceeds of up to $50,000, from time to time, through an “at-the-market” equity offering program under which Jefferies and Stifel would act as sales agent. The Company had sold 1,600,000 common shares under the sales agreement for proceeds of approximately $14,820, net of commissions paid, but excluding estimated transaction expenses. In connection with the Company’s entry into the July 2018 sales agreement with Jefferies and Stifel, the May 2018 sales agreement was mutually terminated by the Company and Stifel. In September 2018, the Company entered into an underwriting agreement with Jefferies and Stifel, relating to an underwritten public offering of 4,500,000 common shares sold by the Company at a public offering price of $14.00 per common share. The Company received net proceeds of $59,220, net of underwriting discounts and commissions, but before offering expenses. In connection with the Company’s entry into the September 2018 underwriting agreement with Jefferies and Stifel, the July 2018 sales agreement was mutually terminated by the Company, Jefferies and Stifel.
In March 2018, the Company and BVF entered into an exchange agreement pursuant to which the Company issued to BVF 2,868,000 Series 1 Preferred Shares in exchange for 2,868,000 common shares which were subsequently cancelled by the Company. The Company filed articles of amendment creating an unlimited number of Series 1 Preferred Shares. The Series 1 Preferred Shares are convertible into common shares on a one-for-one basis subject to the holder, together with its affiliates, beneficially owning no more than 9.99% of the total number of common shares issued and outstanding immediately after giving effect to such conversion (the “Beneficial Ownership Limitation”). The holder may reset the Beneficial Ownership Limitation to a higher or lower number, not to exceed 19.99% of the total number of common shares issued and outstanding immediately after giving effect to such conversion, upon providing written notice to the Company which will be effective 61 days after delivery of such notice. Each Series 1 Preferred Share is also convertible into one common share at any time at the Company’s option without payment of additional consideration, provided that prior to any such conversion, the holder, together with its affiliates, beneficially owns less than 5.00% of the total number of common shares issued and outstanding and such conversion will not result in the holder, together with its affiliates, beneficially holding more than 5.00% of the total number of common shares issued and outstanding immediately after giving effect to such conversion. In the event of a change of control, holders of Series 1 Preferred Shares shall be issued one common share for each outstanding Series 1 Preferred Share held immediately prior to the change of control (without regard to the Beneficial Ownership Limitation), and following such conversion, will be entitled to receive the same kind and amount of securities, cash or property that a holder of common shares is entitled to receive in connection with such change of control. The Series 1 Preferred Shares rank equally to the common shares in the event of liquidation, dissolution or winding up or other distribution of the assets of the Company among its shareholders and the holders of the Series 1 Preferred Shares are entitled to vote together with the common shares on an as-converted basis and as a single class, subject in the case of each holder of the Series 1 Preferred Shares to the Beneficial Ownership Limitation. Any Series 1 Preferred Shares that are ineligible to be converted into common shares due to the Beneficial Ownership Limitation, measured as of a given record date that applies for a shareholder meeting or ability to act by written consent, shall be deemed to be non-voting securities of the Company. Holders of Series 1 Preferred Shares are entitled to receive dividends (without regard to the Beneficial Ownership Limitation) on the same basis as the holders of common shares. The Company may not redeem the Series 1 Preferred Shares. The Company recorded the issuance of Series 1 Preferred Shares and corresponding cancellation of common shares at $7.61 per share, the estimated weighted average cost at which BVF acquired the common shares. The Series 1 Preferred Shares are recorded wholly as equity under ASC 480, with no bifurcation of conversion feature from the host contract, given that the Series 1 Preferred Shares cannot be cash settled and have no redemption features. During the year ended December 31, 2018, BVF converted 1,852,000 Series 1 Preferred Shares in exchange for an equal number of common shares of the Company.
In March 2018, the Company and Teva, entered into a termination agreement terminating by mutual agreement the collaborative development and license agreement dated December 7, 2012, as amended. In connection with the termination, Teva returned and the Company cancelled 1,000,000 common shares that were owned by Teva. Pursuant to the terms of the termination agreement, Teva has also returned, licensed or assigned to the Company certain intellectual property, including certain patent rights and transferred regulatory filings related to TV-45070 to the Company. The termination agreement requires the Company to pay a low single-digit percentage royalty to Teva based on net sales of approved products, if any, resulting from any continued development and commercialization of TV-45070 by the Company or a sublicensee during the period that assigned or licensed patents cover such products. To date, no such sales have occurred. The Company recorded a gain on the termination of the collaboration agreement of $4,398, net of direct costs incurred in connection with the termination and cancellation of 1,000,000 common shares, based on the estimated fair value represented by the market price of the common shares prior to the closing of the transaction.

Income tax expense for the three months ended March 31, 2019 and 2018 arose from the operations of Xenon Pharmaceuticals USA Inc., the Company’s wholly-owned subsidiary in the United States. Deferred income tax assets recorded on the consolidated balance sheets as of March 31, 2019 and 2018 result from the temporary differences between the amounts of assets and liabilities recognized for financial statement and income tax purposes related to the operations of Xenon Pharmaceuticals USA Inc. The realization of deferred income tax assets is dependent upon the generation of sufficient taxable income during future periods in which the temporary differences are expected to reverse. |

| Commitments and Contingencies |
In August 2015, the Company entered into a priority access agreement with Medpace for the provision of certain clinical development services. Under the terms of the agreement, the Company has committed to using Medpace non-exclusively for clinical development services over the five year term of the agreement. In consideration for priority access to Medpace resources and preferred service rates, the Company has committed to $7,000 of services over the term of the agreement, $3,000 of which was paid in the year ended December 31, 2015.
In March 2017, the Company entered into a license, manufacture and supply agreement with a pharmaceutical contract manufacturing organization for the access and use of certain regulatory documents as well as for the manufacture and supply of clinical and commercial drug product to support the development of XEN007. Under the terms of the agreement, the Company will be required to pay a low single-digit percentage royalty on net sales of any products developed and commercialized under the agreement.
In April 2017, the Company acquired XEN1101 (previously known as 1OP2198) from 1st Order pursuant to an asset purchase agreement. 1st Order previously acquired 1OP2198 from Valeant Pharmaceuticals Luxembourg S.a.r.l. (together with other Valeant entities, “Bausch Health”) and the Company has assumed certain financial responsibilities under that agreement. In September 2018, the Company entered into a milestone and royalty buy-out agreement with Bausch Health under which all potential clinical development, regulatory and sales-based milestones and royalties on commercial sales with respect to XEN1101 that may become owed to Bausch Health under the asset purchase agreement were terminated in exchange for a one-time payment of $6,000 which was expensed in the period. Future potential payments to 1st Order related to the XEN1101 program include $500 in clinical development milestones, up to $6,000 in regulatory milestones, and $1,500 in other milestones, which may be payable pre-commercially. There are no royalty obligations to 1st Order.
In July 2017, the Company entered into a license agreement with a pharmaceutical company for the access and use of certain regulatory documents to support the development of XEN007. Future potential payments include $2,000 in clinical development milestones, up to $7,000 in regulatory milestones, plus a low-to-mid single-digit percentage royalty on net sales of any products developed and commercialized under the agreement.
The Company has entered into license and research agreements with third parties that include indemnification provisions that are customary in the industry. These indemnification provisions generally require the Company to compensate the other party for certain damages and costs incurred as a result of third party claims or damages arising from these transactions. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds commercial and product liability insurance. This insurance limits the Company’s exposure and may enable it to recover a portion of any future amounts paid. Historically, the Company has not made any indemnification payments under such agreements and the Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to these obligations for any period presented. |

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean.

That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.
