Are Casino Winnings Taxable in Canada? CRA Rules Explained
For the overwhelming majority of Canadian players, casino winnings are not taxed. Canada treats gambling wins as a windfall rather than income — but there are three real exceptions, and one of them (playing in the United States) catches Canadians off guard every year. This guide explains the rule, the exceptions, and what the courts have actually decided.
Last updated: 23 July 2026. This is general information about how Canadian tax law treats gambling receipts — it is not tax advice. If your situation is anything other than casual recreational play, speak to a Canadian accountant or tax lawyer before filing.
The short answer
If you play recreationally, your winnings from an online casino, a land-based casino, a lottery ticket or a sports bet are not taxable in Canada, and you do not report them on your T1. Canadian tax law reaches “income from a source” — employment, business, property. A lucky night is not a source. Paragraph 40(2)(f) of the Income Tax Act reinforces this on the capital-gains side: no taxable capital gain and no allowable capital loss arises from a chance to win a bet, or from the right to receive winnings on a bet.
The flip side is the part players forget: because a casual gambling win is not income, a casual gambling loss is not deductible. You cannot net a bad year against your salary.
Why winnings are treated as a windfall
The Canada Revenue Agency sets out its position in Income Tax Folio S3-F9-C1, “Lottery Winnings, Miscellaneous Receipts, and Income (and Losses) from Crime.” The Agency’s general view is that a prize from a lottery scheme, and the ordinary run of casual gambling receipts, are windfalls — unsolicited, unearned, not the product of an organised profit-seeking activity — and windfalls are outside the charging provisions of the Act.
That framing is why the same C$50,000 jackpot is tax-free for a player who spins slots twice a month and potentially taxable for someone running a disciplined, full-time advantage-play operation. Nothing about the money changes. What changes is the character of the activity that produced it.
Exception 1: when gambling becomes a business
If gambling stops being a pastime and becomes a commercial enterprise, the profits are business income and are fully taxable — and genuine losses and expenses become deductible against that business income.
Canadian courts apply the source test from Stewart v Canada (2002 SCC 46), asking whether the activity is undertaken in a sufficiently commercial manner. In gambling cases the factors that recur are:
- a genuine, demonstrated intention to profit rather than to be entertained;
- commercial organisation — bankroll management, systematic record-keeping, staking arrangements, a business-like structure;
- frequency and volume of play, and the time devoted to it;
- skill applied to reduce chance, and evidence that the skill reliably produces profit;
- reliance on the winnings as a livelihood.
No single factor decides it. The CRA and the courts look at the whole picture, which is exactly why generic online advice (“you’re safe if you have a day job”) is unreliable.
What the courts have actually decided
Poker has produced the clearest Canadian case law, and the results cut both ways:
| Case | Outcome | Why |
|---|---|---|
| Duhamel v The Queen, 2022 TCC 66 | Winnings held not taxable | Roughly C$6.3M over three years, but the court was not satisfied the play was carried on as an organised business |
| Fournier Giguère v The King, 2022 TCC 132 | Winnings held taxable | Roughly C$1.7M; the player relied on poker to fund his lifestyle |
| Bérubé v The King, 2023 TCC 12 | Winnings held taxable | Roughly C$1.5M; livelihood dependence |
| D’Auteuil v The King, 2023 TCC 3 | Winnings held taxable | Roughly C$5.2M; poker was the primary income source |
| Fournier-Giguère et al. v Canada, 2025 FCA 112 | Appeal dismissed | Federal Court of Appeal confirmed that players who earn a livelihood from poker are carrying on a business |
The size of the win is plainly not the deciding factor — Duhamel involved the largest sums and was not taxed. What mattered was whether the activity had been turned into a commercial enterprise.
Exception 2: income earned on your winnings
The prize itself may be tax-free, but everything the money then earns is ordinary taxable income. Interest in a savings account, dividends, rental income, capital gains on invested proceeds — all reportable in the normal way. A C$500,000 tax-free win that generates C$20,000 of interest produces a T5 and a tax bill on the C$20,000.
Exception 3: winning at a US casino
Cross the border and a different regime applies. The IRS treats gambling income of non-resident aliens as US-source and imposes a default 30% withholding on many categories of winnings. Canadians are typically handed Form 1042-S at the cage showing the amount withheld — that form is the essential document for any later refund claim.
Two routes back exist, and both require filing a US non-resident return (Form 1040-NR), plus an ITIN via Form W-7 if you do not already have one:
- Certain table games. TaxTips.ca notes that winnings from blackjack, baccarat, craps, roulette and big-6 wheel are not subject to the standard withholding treatment; where tax was withheld anyway, it can be claimed back in full.
- The Canada–US treaty. Article XXII(3) of the Canada–US tax treaty lets Canadian residents report US gambling winnings net of US gambling losses for the same period, reducing the amount subject to the 30% withholding. Canada is the only treaty partner whose residents get that deduction — which is why keeping a contemporaneous log of US play matters.
Refund claims are fact-heavy and deadline-bound. If material money is involved, use a cross-border tax specialist rather than filing blind.
Does it matter where you played?
For the tax answer, no. Whether you played on an Ontario-registered site, on Alberta’s newly opened market, on a provincial lottery platform, or on an offshore-licensed site, the CRA analysis is the same — it looks at your activity, not at the operator’s licence.
Where the licence does matter is everything else: who hears your complaint, what player-protection standards apply, and whether your funds are segregated. That is covered in our guide to whether online casinos are legal in Canada and in the maintained Canadian iGaming legality and market-data tracker. If you are in the two open markets, read the province-specific detail in our guides to Ontario’s regulated iGaming market and Alberta’s regulated online casinos. Our shortlist of top-rated online casinos for Canadian players shows which licence each site holds; brand-level detail sits in reviews such as our bet365 Canada review, our BetMGM Canada review and our Jackpot City Canada review.
Records worth keeping
Casual players are not required to keep gambling records, but a simple log is cheap insurance if the CRA ever asks questions — and it is mandatory in practice if you play in the US and want a treaty refund. Keep dates, venue or site, buy-ins, cash-outs, and every 1042-S. Casino account statements and Interac e-Transfer records are usually the easiest reconstruction if you have not kept a log.
FAQ
Do I have to report casino winnings on my Canadian tax return?
Recreational players do not. Casual gambling winnings are treated as a windfall rather than income from a source, so they are not reported on a T1 and no tax is payable on them. If your gambling amounts to a business, the profits are business income and must be reported.
Are online casino winnings taxed differently from lottery or land-based wins?
No. Canadian tax law looks at the character of the activity, not the platform. A recreational win on an online casino, on a provincial lottery ticket or at a land-based table is treated the same way — as a non-taxable windfall for a casual player.
Can I deduct my gambling losses in Canada?
Not as a casual player. Because casual winnings are not taxable income, casual losses are not deductible. Losses only become deductible when the gambling itself is found to be a business, in which case the profits are taxable too.
Do professional gamblers pay tax in Canada?
Yes, where the facts show a business. The Federal Court of Appeal confirmed in Fournier-Giguère et al. v Canada (2025 FCA 112) that players who earn a livelihood from poker are carrying on a business, making the profits taxable business income. Whether a given player crosses that line is a fact-specific question decided on factors such as profit intention, commercial organisation, frequency and livelihood reliance.
How do I get back the 30% withheld by a US casino?
File a US non-resident return (Form 1040-NR) with the Form 1042-S the casino issued, plus Form W-7 if you need an ITIN. Certain table-game winnings are recoverable in full, and Article XXII(3) of the Canada–US tax treaty lets Canadian residents offset US gambling losses against US gambling winnings for the same period. Cross-border filings are technical — get professional help for anything substantial.
Is interest earned on my winnings taxable?
Yes. The prize is a tax-free windfall, but any income the money subsequently generates — interest, dividends, rent, capital gains on investments — is ordinary taxable income and must be reported.
