How does the CRA generally classify winnings from games of chance versus games of skill?

Most Ottawa players who land a nice session at an iGaming Ontario casino and then wonder "do I owe the CRA anything?" are really asking: does it matter what game I was playing? The answer is yes — but probably not in the way you'd expect.

Pure chance: the default is non-taxable

Lottery winnings of any amount are generally not reported or taxed, unless the prize can be considered income from employment, a business or property, or a prize for achievement. The CRA extends this same treatment to most recreational gambling — slots, roulette, blackjack played as a hobby, sports betting, and similar games. The amount or value of a prize received from a lottery scheme is not taxable as either a capital gain or income, unless due to the circumstances applying to the lottery scheme, the prize can be considered to be income from employment, business or property.

The underlying logic matters here. Games of pure chance, like lotteries, lack the badges of trade to which traditional tests of business activity can be applied. Those traditional tests include an evaluation of a taxpayer's profit-making purpose and the commerciality of the activity — but gambling is always undertaken in pursuit of profit. Because everyone who gambles hopes to win, that intention alone doesn't make winnings taxable income.

Where skill enters the picture — and why it matters

This is where the classification genuinely shifts. 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, if the person is carrying on the business of gambling. Skill is one of the key factors that can push someone across that line.

There are exceptional cases where gambling activities have been held to be taxable — cases that relate to taxpayers who applied inside information, knowledge, and skill to their activities. A notable example involved a pool player who would challenge inebriated opponents in cold sobriety, and was held to be taxable on his winnings. The takeaway: if you're systematically exploiting a skill edge to extract consistent profit, the CRA may view that as a business, not recreation.

Whether a taxpayer's activities constitute carrying on a gambling business is a question of fact, determined only by examining all of the circumstances and the taxpayer's entire course of conduct. Although no single factor is conclusive, the CRA considers things like the degree of organization present in the activity, the existence of special knowledge or inside information that reduces the element of chance, and the taxpayer's intention — gambling for pleasure versus gambling as a trade.

One important wrinkle: investment income on winnings is always taxable

Income earned on non-taxable gambling winnings is itself taxable. For example, any interest you earn when you invest lottery winnings must be reported on your return. So even if your casino cashout is completely clean from a tax standpoint, parking those funds in a savings account and earning interest is a different matter.

One other note worth flagging for anyone playing at Ontario-regulated sites: only operators registered with iGaming Ontario and regulated by the AGCO are legally permitted to offer online casino games to Ontario residents. You can confirm a site is legitimate by looking for both the iGaming Ontario and BetGuard logos — their presence signals the site is part of the regulated market.

The CRA's authoritative guidance on all of this lives in Income Tax Folio S3-F9-C1, available at canada.ca. Tax law in this area is genuinely fact-specific, so if your play is anything beyond casual recreation — high volume, consistent profit, a systematic approach — it's worth a conversation with a Canadian tax professional. ConnexOntario (1-866-531-2600) is available if gambling ever becomes something other than entertainment.
