Are Online Casino Winnings Taxable in Canada? (2026 Guide)

This is general information, not tax or legal advice. Tax outcomes depend on your specific facts, and the line between recreational and professional gambling is genuinely fact-dependent. Talk to a CPA or a tax professional before you act on anything in this guide.

In most cases, no — recreational gambling winnings are not taxable in Canada. If you play casino games, slots, sports betting, or poker for fun, the money you win is treated as a “windfall,” not income, and you do not report it on your tax return or pay tax on it. That covers the overwhelming majority of Canadian players.

There is one narrow exception. If you gamble as a business — the bar the courts have set for being a “professional gambler” — your net winnings can be taxed as business income. As we’ll explain, that bar is high, applied case by case, and rarely reached. And a separate point that trips people up: while the winnings themselves are tax-free, any income those winnings generate (interest, investment returns) is taxable like any other income.

Below we walk through the windfall principle, the professional-gambler exception and the case law behind it, the crypto wrinkle, US winnings, and what records to keep even when you owe nothing. Mary, our mascot, would tell you to enjoy the win — we’d add: keep a clean paper trail anyway.

Why winnings are a “windfall,” not income

Canada’s Income Tax Act taxes income from a source — employment, business, property, capital gains. Gambling winnings generally fit none of those. The Canada Revenue Agency’s own guidance, Income Tax Folio S3-F9-C1, treats most lottery and gambling winnings as windfalls that are not included in income.[1]

The CRA folio lists the factors that mark a receipt as a windfall: the taxpayer had no enforceable claim to the payment, made no organized effort to receive it, neither sought nor solicited it, had no expectation it would recur, and did not earn it through any activity carried on for profit.[1] A casino win checks those boxes. You bought a chance; the outcome turned on luck; you had no enforceable right to win.

There’s also a specific provision that closes the capital-gains door. Paragraph 40(2)(f) of the Income Tax Act states that a taxpayer’s gain or loss from disposing of a chance to win, or a right to a prize, in connection with a lottery scheme or a pool system of betting is nil.[2] In plain terms: a lottery ticket or a bet produces neither a taxable capital gain nor a deductible capital loss. This is also why lottery winnings — Lotto 6/49, Lotto Max, scratch tickets — are tax-free on the same windfall principle.[1]

The professional-gambler exception — and why it almost never bites

Here’s where people get nervous, usually after reading a headline. Can the CRA decide you’re a “professional” and tax your winnings? In theory, yes. In practice, almost never for an ordinary player.

The legal question is whether you are carrying on a business of gambling under sections 3 and 9 of the Income Tax Act. The CRA assesses this case by case, looking at the whole picture rather than any single factor: the time and effort you devote, whether you operate in a systematic, business-like way with risk-management strategies, your intention to profit, your reliance on the activity for a living, and whether skill (not just luck) drives the outcome.

The case law shows just how reluctant Canadian courts are to find a gambling business:

• Leblanc v. The Queen, 2006 TCC 680. Two brothers won over $5.5 million net playing government sports lotteries from 1996 to 1999, wagering $10–13 million a year, running a computer program to analyze bets, hiring up to fifteen helpers to buy tickets, and negotiating retailer discounts. Despite all that organization, the Tax Court held the winnings were not taxable. The activity turned on luck — the odds could not be beaten by skill — so it was a personal pursuit, not a business.[3]
• Cohen v. The Queen, 2011 TCC 262. A lawyer quit his job to play online poker full time, studied the game, used note-taking software, and played 6–8 hours a day, seven days a week. The Tax Court still found he was a hobby player, which also meant his losses were not deductible.[4]
• Radonjic v. Canada (CRA), 2013 FC 916. A taxpayer supported himself on online poker winnings for more than three years. The Federal Court held he was not carrying on a business; his winnings were not taxable.[4]
• Duhamel c. Canada, 2022 TCC 66. Jonathan Duhamel, the 2010 World Series of Poker Main Event champion (a prize of roughly US$9 million), was reassessed by the CRA as earning business income. The Tax Court disagreed, finding he did not use any genuine risk-management or risk-mitigation system and was therefore not operating as a businessman in his poker play. The winnings were not taxable.[5]

That body of law leans heavily toward “not a business.” But the line is real, and it can be crossed.

The important counterweight: Fournier-Giguère v. Canada, 2025 FCA 112. The Federal Court of Appeal upheld Tax Court findings that three full-time poker players were carrying on a business and owed tax on their winnings — reassessed amounts ranging from roughly $1.45 million to $5.24 million across several years (2008–2012). The court found their play was not casual or recreational: it was pursued with clear commercial intent, a high degree of commitment, and demonstrable skill, effectively to earn a living.[6]

So the honest answer is that the professional-gambler line is genuinely ambiguous and fact-driven. Duhamel won; Fournier-Giguère lost. What separates them is fact-specific — the degree of system, organization, risk management, and reliance on the activity as a livelihood — which is exactly why a CPA’s read on your facts matters if you’re anywhere near that line. For a casual or even fairly frequent recreational player, though, you are not close to it.

Edge cases at a glance

• Recreational player, casino/slots/sports/poker winnings — Not taxable in Canada. Windfall, not income.[1]
• Lottery winnings (Lotto Max, 6/49, scratch tickets) — Not taxable. Windfall; para. 40(2)(f) gain is nil.[1][2]
• Professional gambler carrying on a business — Taxable on net winnings. Business income under ss. 3 and 9.[6]
• Interest or investment income earned on winnings — Taxable. Property income, like any other interest/return.[1]
• Crypto winnings that appreciate before you cash out — Possibly taxable on the appreciation. Crypto disposition can trigger capital gains.[7]
• Winnings from gambling in the US — US side: 30% withheld; Canada side: not taxable for recreational players. US source income; treaty relief available.[8][9]
• Gambling losses (recreational player) — Not deductible. Mirror of winnings being non-taxable.[4]

The crypto wrinkle

This is where a “tax-free win” can quietly create a tax bill, and it’s relevant to anyone using a crypto casino — a topic we cover in our crypto-casino content.

The CRA treats cryptocurrency as a commodity, not as money.[7] So even though the gambling win itself follows the windfall rule, the crypto you hold afterward is property that can gain or lose value. When you later sell, swap, or spend it, that’s a disposition, and any increase in value from when you received it to when you dispose of it can be a capital gain — half of which is included in income at your marginal rate.[7]

A simplified example: you win crypto worth C$1,000 at the time of the win, hold it, and later cash out when it’s worth C$1,500. The C$500 of appreciation can be a capital gain on disposition, even though the original C$1,000 win was a tax-free windfall. The taxable event is the appreciation of the property, not the gambling.

The mechanics of crypto-gambling taxation can get more involved than this — for instance, how and when fair market value is fixed, and how frequent trading might recharacterize gains as business income.[7] This is a strong “talk to an accountant” zone if you play in crypto at any scale.

Cross-border: US casino winnings

Win at a US casino and the rules change at the border. Under US law, the casino generally withholds 30% on certain gambling winnings paid to non-residents (commonly above set thresholds, e.g., on many slot and similar payouts).[8] You’ll receive a Form 1042-S documenting the income and the tax withheld.[8]

The good news: the Canada–US tax treaty lets Canadians recover some or all of that withholding by offsetting US gambling losses against US gambling winnings from the same year. To claim it, you file a US non-resident return (Form 1040-NR with Schedule NEC), report the winnings and offsetting losses, attach the 1042-S, and obtain a US Individual Taxpayer Identification Number (ITIN) using Form W-7.[8][9] Refund claims can generally be filed for up to three prior years, so keep the paperwork.[9]

To support the claim you need proof of your US gambling losses — a contemporaneous log of dates, casinos, and amounts won and lost.[9] On the Canadian side, recreational US winnings remain non-taxable here under the same windfall principle; the US withholding and recovery is a separate, US-side process.

Record-keeping: keep a paper trail even when you owe nothing

Most recreational players owe no tax, so why bother? Because the burden of explaining a deposit can fall on you, and good records protect you:

• A simple gambling log — dates, venues or sites, amounts won and lost.
• Withdrawal and deposit confirmations, and bank or e-wallet statements showing money in and out.
• For US winnings: every 1042-S, plus your loss log to support a treaty refund.
• For crypto: the fair market value (in CAD) at the time you received and disposed of each amount, so you can compute any gain.
• If you’re anywhere near the professional line, records of time spent, strategies used, and how you fund your play — the same factors a court would weigh.

None of this is about reporting tax-free winnings. It’s about being able to show that a large deposit was a tax-free gambling win, not unreported income, if anyone ever asks.

When you should talk to an accountant

For most readers, the answer to the title question is a clean “no, and there’s nothing to file.” But here’s when to get professional advice rather than rely on a blog post:

• You gamble full time, rely on it for income, or play in a systematic, business-like way (the professional line).
• You win or play in crypto at any meaningful scale.
• You have significant US winnings and want to recover the 30% withholding.
• You’ve invested winnings and aren’t sure how to report the income they generate.
• You’ve received any letter or query from the CRA about your gambling.

A CPA or tax lawyer will look at your specific facts. We can’t, and this guide doesn’t try to.

Frequently asked questions

Do I have to report casino winnings in Canada?

For recreational players, no. Gambling winnings are treated as a windfall and are not included in income, so there’s nothing to report on your return.[1] If the CRA were to treat your gambling as a business, that changes — but that’s the rare exception, not the norm.

Are online casino winnings taxable?

Generally no. The windfall principle applies regardless of whether you played in person or online; a recreational player’s online casino, slot, sports-betting, or poker winnings are not taxable in Canada.[1]

What about professional poker players?

It depends, and the courts genuinely split on it. In Duhamel (2022) a WSOP champion’s winnings were held non-taxable, while in Fournier-Giguère (2025 FCA) three full-time players were found to be carrying on a business and were taxed.[5][6] If poker is your livelihood and you run it in a systematic, business-like way, get professional advice.

Do I pay tax on crypto casino winnings?

The gambling win itself follows the windfall rule, but the crypto you hold is property. If it appreciates between the time you win it and the time you sell, swap, or spend it, that appreciation can be a taxable capital gain on disposition.[7] Crypto play warrants a conversation with an accountant.

Are US casino winnings taxable for Canadians?

The US generally withholds 30% on certain non-resident gambling winnings, documented on a Form 1042-S. Canadians can recover some or all of it under the Canada–US tax treaty by filing a US non-resident return, offsetting US losses, and obtaining an ITIN.[8][9] On the Canadian side, recreational US winnings are not taxable here.

Can I deduct gambling losses in Canada?

Not for recreational players. Because your winnings aren’t taxed, your losses aren’t deductible — the two go together.[4] Only if gambling is found to be a business would losses be relevant, and that’s the same narrow exception discussed above.
