If I gamble online regularly but do not consider myself a professional, how should I think about my tax obligations?

Good news for most Ontario players: gambling winnings are not treated as taxable income under Canadian tax law — but that general rule has a meaningful catch worth understanding before you assume it applies to you.

The default position: winnings are not income

Profits derived from bookmaking or from the operation of any gambling establishment constitute income from a business — that's the clearest taxable scenario. But for ordinary players, the CRA's long-standing position is different. You do not have to pay the CRA any taxes or fees of any kind on lottery and sweepstakes winnings in Canada. The same principle generally extends to casino and online gambling winnings for recreational players: the money you win is considered a windfall, not income, and windfalls are not taxable.

Where "regular but not professional" gets complicated

The tricky part is that "I don't consider myself a professional" isn't the test the CRA actually applies. The agency looks at the facts of how you gamble, not how you label yourself. According to CRA's own folio on gambling profits, the relevant factors include:

• The degree of organization present in the pursuit of the activity
• The existence of special knowledge or inside information that enables the taxpayer to reduce the element of chance
• The taxpayer's intention to gamble for pleasure compared with any intention to gamble for profit as a means of gaining a livelihood
• The extent of the gambling activities, including the number and frequency of bets

There are some exceptional cases where gambling activities have been held to be taxable — and these relate to taxpayers who applied inside information, knowledge, and skill to their activities. Think systematic sports bettors using proprietary models, or poker players who play high-volume, treat it as a second income, and keep meticulous records of wins and losses. Playing slots or blackjack regularly on a licensed Ontario site, even frequently, is a very different picture.

If the taxpayer is in the business of gambling, proceeds and losses are considered for income tax purposes — and this may include skill-based activities such as poker, which may constitute a business of gambling when conducted in a sufficiently organized and commercial manner.

What this means practically

For the vast majority of regular recreational players on Ontario's regulated sites — people who enjoy the games, deposit their own money, and treat winnings as a bonus rather than a paycheque — the CRA's position is that those winnings are non-taxable. The line gets blurry only when gambling starts looking structurally like a business: systematic staking plans, profit-focused record-keeping, treating it as a primary or supplementary livelihood.

If you're somewhere in that grey zone — say, a serious poker player who regularly books significant wins — a conversation with a Canadian tax professional is genuinely worth it. The CRA's folio on this topic (Income Tax Folio S3-F9-C1) is publicly available on Canada.ca and is the primary source to read if you want the full technical picture straight from the agency.

One practical note: Ontario's regulated online casinos, accessible through the iGaming Ontario framework and verifiable by the iGaming Ontario and BetGuard logos on their sites, keep transaction records. If you ever needed to demonstrate the recreational nature of your play, that paper trail can actually work in your favour.
