The Canada Revenue Agency calls most poker winnings windfalls. The Tax Court of Canada has agreed — including in a 2011 case where the taxpayer was, by his own description, a full-time professional player. The line between non-taxable windfall and taxable business income is one of the more contested questions in Canadian gambling tax law. Here's where it sits in 2026.

TL;DR: Canadian residents generally do not pay tax on poker winnings, because the CRA treats them as windfalls. The exception is when poker rises to a business — a high practical bar that the courts have largely declined to find, even for full-time players. If you cash U.S. tournaments, you face 30% U.S. withholding that you can recover under Article XXII paragraph 3 of the Canada-U.S. tax treaty.
The windfall doctrine
The CRA's default treatment of gambling winnings — including poker — is that they are windfalls, not income from a source. The Income Tax Act doesn't tax windfalls; only income from one of the recognized sources (employment, business, property, capital gains) is taxable. The CRA's published guidance on windfalls is in Folio S3-F9-C1, "Lottery Winnings, Miscellaneous Receipts, and Income (and Losses) from Crime," updated effective July 3, 2020. The factors that mark something as a windfall: it was unexpected, the recipient had no enforceable right to it, and it was not a customary source of income.
Poker winnings fit the windfall mold for nearly every Canadian player, including many serious recreational players. The default is non-taxable.
When the CRA looks at you as a business
The exception is when the activity rises to a business. The legal foundation is the Supreme Court's two-stage "pursuit of profit" test from Stewart v Canada, 2002 SCC 46 — established in a real-estate case and applied to gambling characterisation ever since. The taxpayer must be carrying on the activity in pursuit of profit, and the activity must have sufficient commercial elements that it cannot reasonably be characterised as a personal endeavour.
Applied to poker, the CRA and the courts typically look at:
- Frequency and regularity of play.
- Skill of the taxpayer relative to the games played.
- Existence of a system or method — bankroll management, study habits, table-selection discipline.
- Time devoted to the activity.
- Whether poker is the taxpayer's main source of income.
- Whether the taxpayer holds themselves out as a professional.
No single factor is decisive, and the test is famously fact-specific. The court asks, in essence: does this look like a business or does it look like a pursuit of personal pleasure that happens to generate winnings? Even when the factors point toward "business," the chance element of poker has historically pulled the conclusion back toward "windfall."
Cohen v The Queen (2011 TCC 262)
The most-cited modern Canadian poker case is Cohen v The Queen, 2011 TCC 262. Mr. Cohen had quit his job as a lawyer to play online poker full-time. His activity met most of the textbook business indicators: 6–8 hours per day, seven days per week; books and articles read; seminar attended; opponent-tracking software in use; a documented strategy targeting inexperienced players. He logged $80,000 in winnings against $200,000 invested.
Despite all that, the Tax Court of Canada held that Mr. Cohen was not carrying on a business — he was a hobby poker player whose activity, however systematic, did not have sufficient commercial features to make it a source of income under the Stewart test. His winnings remained windfalls; his losses, correspondingly, could not be deducted against his other income. The court emphasised that the chance element of poker distinguishes it from a typical commercial activity even when the player invests all the time and effort that a professional would.
Cohen is the case Canadian poker professionals point to. It does not say that no poker player can ever be carrying on a business — but it sets a high practical bar. A 2026 Canadian poker player whose facts mirror Cohen's should expect, by default, that the CRA will treat their winnings as non-taxable windfalls.
If treated as a business
For the rare Canadian poker player whose activity is classified as a business — typically scenarios involving staking pools, formal coaching businesses, or hybrid activities where the gambling is mixed with services — the consequences are full-rate income inclusion: gross winnings as business income at marginal rates, deductions allowed for ordinary and necessary business expenses (buy-ins, travel, lodging, coaching, software, training), and capital cost allowance on equipment. Net business losses can offset other income.
GST/HST is generally not applicable to gambling winnings themselves, because they are not consideration for taxable supply. Service-side income (coaching, content) may be GST/HST applicable depending on volume — consult a tax professional for the specific GST treatment of any service component.
Cross-border: the W-2G refund
The most common Canadian poker tax issue is not domestic — it's the U.S. withholding. When a Canadian resident cashes a U.S. tournament for a reportable amount, the cardroom withholds 30% under U.S. non-resident gambling rules. Under Article XXII paragraph 3 of the Canada-U.S. tax treaty, Canadian residents can offset gambling losses against gambling winnings and recover the over-withheld amount via a U.S. Form 1040-NR filing.
For serious tournament players, the recovery is substantial. A Canadian who wins a $50,000 cash and has $20,000 in documented U.S. tournament losses for the same year can typically recover most of the $15,000 withheld at the cage. The 1040-NR filing requires session-level documentation of the offsetting losses — exactly the kind of evidence PokerCharts is designed to produce.
One caveat for tax year 2026 and beyond: the U.S. side of cross-border filing changed materially with the One Big Beautiful Bill Act, which capped U.S. gambling-loss deductions at 90% of losses starting tax year 2026. Under the Article XXII paragraph 3 mechanics, Canadians offsetting losses against winnings on a 1040-NR will feel the 90% cap too. Recovery amounts on the same fact pattern are smaller post-OBBBA than they were before. See our U.S. poker tax guide for the federal-side details, and bring a cross-border CPA into the conversation before filing.
Provincial considerations
Provincial income tax in Canada follows federal characterisation. If your poker income is a federally non-taxable windfall, it is also non-taxable provincially. Quebec residents file a separate provincial return but apply the same characterisation principles. There are no provincial gambling-specific income tax regimes; the provinces tax operators, not players.
How PokerCharts helps
PokerCharts logs every session — date, venue, game type, buy-in, cash-out — at the moment it happens. The jurisdiction-aware tax reporting feature generates an annual summary built specifically for Canadian filers: session log, gross-loss aggregation suitable for a 1040-NR refund claim, and CSV export your accountant can drop straight into a U.S. non-resident filing or use as windfall-evidence documentation for the CRA. If your poker activity is ever the subject of a CRA inquiry, having a complete contemporaneous record is the single highest-value protection.
PokerCharts is free for your first 10 sessions and then $1.99 USD/month on the annual plan ($23.95/year — our cheapest tier). For Canadian players who play regular U.S. tournaments, the W-2G evidence collection alone usually pays for the subscription several times over.
If you also play in the US or Germany
The U.S. side of cross-border play — Schedule 1 vs Schedule C, W-2Gs, the new OBBBA 90% cap, the session method — is covered in our U.S. poker tax guide. If you're a Canadian who has spent time in Germany or has German tax residency questions, our German poker tax guide covers the very different European framework.
