What factors does the CRA typically look at when deciding whether gambling is a hobby or a taxable business activity?

Canada's default position on gambling winnings is straightforward: they're not taxable. Lottery and certain other winnings are non-taxable in Canada — unless the taxpayer is in the business of gambling, in which case both proceeds and losses are considered for income tax purposes. The hard question, then, is what actually pushes someone from the "lucky hobbyist" side of that line into taxable territory. The CRA's answer is nuanced, and it's genuinely fact-specific.

The baseline: gambling is almost never a business

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. That's a direct quote from the Tax Court of Canada, and the CRA has adopted this position in its own published guidance (Income Tax Folio S3-F9-C1). So frequency alone — playing online casino games every day, depositing regularly on a Toronto-licensed platform — does not make you a business operator. The bar for crossing into taxable territory is genuinely high.

It's also worth noting that the "reasonable expectation of profit" test is not supportable in law as a basis to determine if a taxpayer's activities constitute a source of income under the Act. The CRA removed that older test from its guidance. Showing up with a profit motive isn't enough on its own.

What actually tips the scale: skill, system, and inside knowledge

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 be determined only by an examination of all of the circumstances and the taxpayer's entire course of conduct. In practice, the CRA and the courts have focused on a cluster of factors:

• Skill and knowledge over chance. There are some exceptional cases where gambling activities have been held to be taxable — but these cases relate to taxpayers who applied inside information, knowledge, and skill to their activities. The classic example in Canadian case law involves a pool player who deliberately targeted inebriated opponents — exploiting a genuine informational edge, not just playing the odds.
• Systematic, business-like conduct. A business is an activity that you intend to carry on for profit and there is evidence to support that intention. Evidence of a business-like approach — dedicated record-keeping, a defined strategy, tracking results methodically, treating it as a primary income source — all weigh toward the business side.
• Pursuit of profit as the dominant purpose. Where there is a suspicion that the taxpayer's activity is a hobby or personal endeavour rather than a business, the taxpayer's so-called reasonable expectation of profit is a factor, among others, which can be examined to ascertain whether the taxpayer has a commercial intent. It's one input among many, not a standalone test.
• Degree of organization and effort. Does the person dedicate substantial time, maintain detailed logs, and operate with the discipline of someone running a commercial enterprise? Casual recreational play — even high-volume recreational play — typically doesn't satisfy this.

For the vast majority of people playing on Ontario's regulated online casino platforms, none of these conditions apply. Spinning slots or playing blackjack for entertainment, even regularly, is recreational activity. The CRA's own guidance makes clear that if the business definition were applied literally and mechanically, it would include anyone who consistently and regularly placed bets on gaming tables — but gambling activities are not generally regarded as commercial activities except under very exceptional circumstances.

What this means practically for Toronto players

If you're playing on a licensed Ontario site (you can verify registration at the iGaming Ontario registry), your winnings are almost certainly non-taxable under the CRA's established position. The edge cases — professional poker players with documented systems, people who demonstrably exploit skill-based advantages — are genuinely rare, and even those situations are contested and fact-dependent. If you think your situation might be unusual, a Canadian tax professional is the right person to ask; this is a nuanced legal determination, not a formula.

One practical note: if you're ever in doubt about your play habits, ConnexOntario (1-866-531-2600) is there — and Ontario's regulated sites are required to be 19+ only.
