How should I handle taxes if I gamble online regularly but do not consider myself a professional?

Canada's tax treatment of gambling winnings is genuinely more player-friendly than most people expect — but it hinges on one key distinction that the CRA draws carefully.

For the vast majority of recreational players, winnings are not taxable. An individual's gambling activities only produce taxable business income if those activities constitute a source of income — meaning the person is effectively carrying on the business of gambling. If you play for entertainment, the CRA treats your wins and losses as personal receipts, not income. In the case of hobbies, neither amounts received nor expenses incurred are included in the income computation for tax purposes. So a recreational player who has a good run at an Ontario-licensed online casino doesn't owe the CRA a cent on those winnings.

Where the line actually sits

Whether a taxpayer's activities constitute carrying on a gambling business is a question of fact, determined by examining all the circumstances and the taxpayer's entire course of conduct. The criteria include: the degree of organization in the activity, the existence of special knowledge or inside information that reduces the element of chance, the taxpayer's intention to gamble for pleasure versus profit as a means of livelihood, and the extent of gambling activities including number and frequency of bets.

You've said you don't consider yourself a professional, and for most people reading this, that self-assessment is probably accurate. Frequency alone doesn't flip the switch — playing regularly doesn't make you a business. What the CRA looks for is a systematic, business-like approach: detailed record-keeping aimed at extracting profit, exploiting a genuine skill edge, and relying on gambling as a primary livelihood. The exceptional cases where gambling has been held taxable involve taxpayers who applied inside information, knowledge, and skill to their activities — not someone who simply plays slots or blackjack online most weekends.

One thing worth knowing: income earned on gambling winnings is taxable. For example, any interest you earn when you invest lottery winnings must be reported on your return. So if you take a big win and park it in a savings account, the interest that grows from it goes on your T1 — even though the original win does not.

If you ever find yourself wondering whether your activity has crossed into professional territory — perhaps you've developed a genuine poker skill set, you track every session meticulously, and gambling represents a meaningful share of your household income — that's the moment to talk to a tax accountant or lawyer, not a casino information site. The line can blur, and the consequences of getting it wrong run in both directions (you might be paying tax you don't owe, or not paying tax you do).

For Ontario players, there's one practical angle worth keeping in mind: stick to operators registered with iGaming Ontario. Regulated sites display both the iGaming Ontario and BetGuard logos, which is your clearest signal you're playing in the legal market. Playing on unregistered offshore sites doesn't change your Canadian tax position, but it does remove every other consumer protection you'd otherwise have. If you ever need a hand keeping gambling in check, ConnexOntario is available at 1-866-531-2600 — and the legal age to play in Ontario is 19+.

The short version: as a recreational player in Ontario, your winnings from licensed online casinos are almost certainly not taxable. Keep it that way by playing for fun, not as a livelihood — and if your situation genuinely starts to look more commercial, get professional tax advice before filing.
