Does the CRA treat winnings from skill-based games like poker differently from luck-based games like slots for tax purposes?

Your real concern here is almost certainly this: if I win at poker, does the CRA come after me in a way they wouldn't if I'd just hit a jackpot on a slot? The honest answer is: the game type matters less than you'd think, and the distinction that actually drives the CRA's analysis is something else entirely.

The baseline: gambling winnings are generally not taxable in Canada

The CRA lists lottery winnings of any amount as non-taxable — unless the prize can be considered income from employment, a business, or property, or a prize for achievement. That same logic extends to casino and online gambling winnings for the typical recreational player. 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.

So the question of whether you play poker or slots is almost beside the point on its own. What the CRA actually cares about is whether your gambling constitutes a source of income — i.e., whether you're carrying on a gambling business.

Where skill genuinely enters the picture

Here's where poker players need to pay closer attention than slot players. 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; games of pure chance, like lotteries, lack the badges of trade to which the traditional tests of business activity can be applied.

Slots are essentially a pure-chance game, which makes it very hard for the CRA to characterize a slots player as running a business. Poker is different. There are exceptional cases where gambling activities have been held taxable — these cases relate to taxpayers who applied inside information, knowledge, and skill to their activities. For example, in Luprypa v. The Queen, a pool player who in cold sobriety would challenge inebriated pool players to a game was held to be taxable on his winnings. The principle carries over to poker: a player who systematically exploits skill advantages over weaker opponents can start to look, in the CRA's eyes, more like a professional running a business than a hobbyist chasing luck.

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. There's no bright line — the CRA looks at things like consistency of profit, time devoted, level of expertise, and whether you treat it in a businesslike way.

One thing worth knowing: if you're playing on any of Ontario's regulated online platforms (you can confirm a site is legitimate by checking for the iGaming Ontario and BetGuard logos), your account history creates a record. That's not a reason for concern if you're a recreational player — but it does mean serious grinders have a paper trail. Anyone 19+ can play on these sites; if gambling ever starts causing stress rather than entertainment, ConnexOntario (1-866-531-2600) is there.

The practical upshot for most Ontario players

A recreational poker player who wins occasionally at an Ontario-licensed online site is in essentially the same position as someone who wins on slots: the winnings are not taxable. If real skill or merit plays a part in determining the distribution of the prize, the scheme is not a lottery — unless it is based essentially on chance and the degree of skill is minimal. That means poker winnings don't get the blanket "lottery exemption" that slot jackpots might, but they still escape tax as long as you're not operating as a business.

The threshold where things shift — regular play, systematic strategy, treating it as a primary or significant income source — is more likely to be crossed by a poker player than a slots player, simply because skill-based play is more amenable to businesslike structure. But the game label alone doesn't trigger tax; your conduct does. If you're a high-volume player who is genuinely uncertain about your situation, a Canadian tax professional is the right call — this is a facts-and-circumstances analysis, not a simple rule.
