Do I need to report online poker winnings to the CRA?

For most Ottawa poker players — recreational players grinding the tables on a licensed Ontario site after work — the answer is no, you don't owe the CRA a dime on those winnings. But the word "most" is doing real work in that sentence, and the exception matters.

The default rule: gambling winnings aren't taxable income in Canada

Lottery and certain other winnings are non-taxable in Canada — but if a taxpayer is in the business of gambling, the CRA considers the proceeds and losses for income tax purposes. That two-part principle is the whole framework. Lottery winnings of any amount are excluded from income unless the prize can be considered income from employment, a business or property, or a prize for achievement. The CRA applies the same logic to gambling winnings generally: a windfall is not a source of income.

To decide whether something is a windfall, the CRA looks at factors including whether the taxpayer made no organized effort to receive the payment, had no customary or specific expectation to receive it, had no reason to expect it would recur, and whether the payment was not earned as a result of any activity or pursuit of gain carried on by the taxpayer. For a casual Ottawa player who fires up an Ontario-registered poker room on evenings and weekends, those factors all point toward windfall — and therefore non-taxable.

The exception: when poker becomes a business

This is where poker diverges from, say, slots. Poker involves skill, and the CRA knows it. If your poker activity starts to look like a business — systematic, profit-driven, your primary or significant secondary source of income — the analysis shifts. In the case of hobbies, neither amounts received nor expenses incurred are included in the income computation for tax purposes, and any excess of expenses over receipts is a personal or living expense. The flip side: if the activity rises above a hobby and constitutes a genuine business, winnings become taxable business income — and losses become deductible.

There's no bright-line rule for when a poker player crosses into "business" territory. Courts and the CRA look at the totality: How often do you play? Do you keep records, study the game, manage a bankroll systematically? Is this your livelihood or a meaningful income stream? A hobbyist who occasionally wins a few hundred dollars on a licensed Ontario poker site is nowhere near that line. Someone playing high-stakes cash games or tournaments full-time, treating it with the discipline of a profession, may well be on the other side of it.

A note on interest earned on winnings

One nuance worth knowing: the winnings themselves may be tax-free, but what you do with them isn't. Income earned on non-taxable amounts is taxable — for example, any interest earned when you invest lottery winnings must be reported on your return. Park your poker profits in a HISA or invest them, and the returns become reportable income.

Keep records regardless

Even if you're confident you're a recreational player, it's worth keeping a basic log of sessions — dates, buy-ins, results, platform. If a taxpayer states that the source of funds is lottery or other winnings, the CRA may request documents that support the winnings and losses for all significant amounts. A simple spreadsheet costs you nothing and answers any question a CRA auditor might raise.

One final practical point: make sure any Ontario site you play on is actually registered under the provincial framework. You can verify this through the official iGaming Ontario registry — legitimate sites display both the iGaming Ontario and BetGuard logos. Playing on an unregistered offshore site doesn't change your Canadian tax obligations, but it does remove every other protection you'd otherwise have.

Tax law in this area is genuinely fact-specific, and this answer is informational, not professional tax advice. If you're playing seriously enough that the business question feels relevant to your situation, a Canadian tax accountant familiar with gambling income is worth the conversation.
