Is there a difference in how the CRA views winnings from poker compared to slots?

For most Ottawa players, the honest answer is: the game type doesn't determine your tax status — your relationship to the game does. Slots and poker sit at opposite ends of the skill spectrum, but the CRA's framework applies the same underlying test to both.

The default rule: gambling winnings are not taxable income

Lottery and certain other winnings are non-taxable in Canada. That general principle covers casino gambling too — slots, table games, and poker alike. 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. So a recreational player who spins slots or plays a few MTTs on a regulated Ontario site owes nothing to the CRA on those winnings, regardless of the amounts.

Where poker genuinely differs — the skill and business question

Here's where the game type starts to matter, practically speaking. 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. And the CRA's own guidance acknowledges that games of pure chance, like lotteries, lack the badges of trade to which the traditional tests of business activity can be applied.

Slots are pure chance — there is no decision-making after you set your bet. It would be essentially impossible for the CRA to characterize slot play as a "business" in the legal sense, because there's no skill element to point to. Poker is different. There are exceptional cases where gambling activities have been held to be taxable, and these cases relate to taxpayers who applied inside information, knowledge, and skill to their activities. The CRA's folio even cites a case involving a pool player who exploited a systematic skill advantage — the principle extends to any game where a taxpayer can demonstrate they are consistently extracting profit through ability rather than luck.

That said, the threshold is high. The issue of whether a taxpayer's activities are such that they can be considered to be carrying on a gambling business is a question of fact that can only be determined by an examination of all of the circumstances and the taxpayer's entire course of conduct. Frequency alone doesn't do it — 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 factors that tip a poker player toward "business" territory include: playing full-time or near-full-time, treating it as a primary income source, maintaining detailed records, operating with a systematic strategy, and being able to demonstrate consistent long-run profitability. A casual player grinding a few evenings a week on a registered Ontario site is not in that category.

Practical takeaway for Ottawa players

If you play slots recreationally, your winnings are almost certainly not taxable — there is no credible pathway for the CRA to characterize pure-chance play as a business. If you play poker seriously and it constitutes a meaningful, systematic source of income, the picture is murkier, and the CRA could take the position that you're carrying on a business — meaning winnings would be taxable, but losses and expenses could also be deductible.

One thing that doesn't change with game type: you should be playing on a site registered with iGaming Ontario and regulated by the AGCO. Regulated sites display the iGaming Ontario logo alongside the BetGuard logo — that's your quickest confirmation you're in the legitimate market. The full list of registered operators is at the official iGaming Ontario registry.

Tax law here is genuinely complex and fact-specific. If you're playing poker at a level where the business question is even remotely live, a Canadian tax professional is worth consulting — this is not an area where general guidance substitutes for advice on your specific circumstances.
