Does the CRA treat winnings from poker differently than winnings from slots or roulette?

Poker does sit in a different conceptual category than slots or roulette under Canadian tax law — but the reason is more nuanced than most people realize, and the game itself isn't the deciding factor. The real distinction comes down to the nature of the activity, not the name on the table.

The baseline rule: gambling winnings are generally not taxable

Lottery winnings are listed among amounts the CRA does not require you to report or pay tax on, unless the prize can be considered income from employment, a business, or property. The same principle extends to casino winnings broadly — lottery and certain other winnings are non-taxable in Canada; however, if the taxpayer is in the business of gambling, the proceeds and losses are considered for income tax purposes.

Slots and roulette are pure games of chance. Games of pure chance, like lotteries, lack the badges of trade to which the traditional tests of business activity can be applied. So a recreational player who hits a jackpot on an Ontario-registered online slot, or cleans up at a roulette table, almost certainly walks away with a non-taxable windfall. The CRA looks at whether the receipt qualifies as a windfall, and factors indicating a windfall include: the taxpayer made no organized effort to receive the payment, had no customary or specific expectation to receive it, had no reason to expect the payment would recur, and the payment was not earned as a result of any activity or pursuit of gain.

Where poker is different — and why it matters

Poker is a game of skill mixed with chance, and that combination is what opens the door to a different tax treatment. An individual's gambling activities may result in taxable business income or a business loss if those activities constitute a source of income — that is, carrying on the business of gambling. Determining the commerciality of gambling can be challenging.

That said, the CRA doesn't automatically tax poker winnings just because the game involves skill. Gambling — even regular, frequent and systematic gambling — is something that by its nature is not generally regarded as a commercial activity except under very exceptional circumstances. The exceptional cases where gambling activities have been held to be taxable relate to taxpayers who applied inside information, knowledge and skill to their activities. The CRA's own folio cites a case where a pool player who in cold sobriety would challenge inebriated pool players to a game was held to be taxable on his winnings — the point being that he was systematically exploiting an edge, not gambling recreationally.

For a Toronto player grinding online poker tournaments or cash games on a registered Ontario platform, the question the CRA would ask is whether the activity looks like a business: Is there a systematic approach? Dedicated time and effort? An expectation of consistent profit? Detailed records? If the honest answer is yes to most of those, the CRA may treat net winnings as business income — which also means losses could be deductible. If you're playing recreationally, even regularly, the answer almost certainly remains non-taxable.

One important wrinkle on any winnings

Regardless of game type, any interest that you earn when you invest your winnings must be reported on your return. The winnings themselves may be tax-free; returns generated by putting them to work are not.

If you're playing on Ontario's regulated market — look for the iGaming Ontario and BetGuard logos on any site you use as confirmation it's a properly registered operator — and you think your poker activity might cross into business territory, a conversation with a Canadian tax professional is worth it. The CRA's full position is set out in Income Tax Folio S3-F9-C1 on canada.ca. This answer is for general information only and doesn't substitute for personal tax advice. If gambling ever becomes a source of stress rather than entertainment, ConnexOntario (1-866-531-2600) is there — and you need to be 19+ to play on any Ontario-registered platform.
