Does the frequency with which I play at Ontario online casinos affect how the CRA might view my gambling winnings?

Picture two Ottawa residents who both play at licensed Ontario online casinos. One logs in a few times a year for a bit of fun. The other plays daily, tracks results in a spreadsheet, and treats it as a serious pursuit. Their winnings look identical on paper — but the CRA might view them very differently. Here's why.

The default rule: gambling winnings aren't taxed

Lottery and gambling winnings are generally not subject to income tax unless, in the case of gambling winnings, the amounts are earned by the taxpayer through carrying on a business. That's the baseline. For the overwhelming majority of recreational players in Ontario — people who enjoy slots, blackjack, or poker on a licensed platform as a pastime — winnings are simply not reportable income. Full stop.

Canadian courts have generally held that lottery and gambling winnings are not considered to be a "source" of income for tax purposes, unless in the case of gambling winnings they were earned through the carrying on of a business, and have therefore generally not been taxed under the Canadian income tax system.

Where frequency becomes relevant — and where it doesn't

So does playing more often put you at risk? Technically, frequency is one of the factors the CRA considers — but it's far from the only one, and it's rarely decisive on its own.

Usually the frequency and systematic nature of an activity would be indicative of a business. However, the CRA's own folio makes clear that this general principle doesn't translate neatly to gambling. 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.

The issue of whether a taxpayer's activities are such that he or she 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. Although no single factor may be conclusive, the following criteria should be considered: 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 as compared with any intention to gamble for profit as a means of gaining a livelihood, and the extent of the taxpayer's gambling activities, including the number and frequency of bets.

Notice that frequency sits at the end of that list, alongside three other criteria. Playing every day at an Ontario online casino does not, by itself, make you a gambling "business." What matters more is whether you're applying systematic skill to reduce the element of chance, whether gambling is your primary livelihood, and how organized and profit-driven your approach is.

The skill factor — especially for poker players

The cases where the CRA has actually taxed gambling winnings almost always involve skill, not just volume. There are some exceptional cases where gambling activities have been held to be taxable — however, these cases relate to taxpayers who applied inside information, knowledge and skill to their activities. 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.

If you're a recreational slots player in Ottawa who happens to play three nights a week, the CRA's framework is not designed to catch you. If you're grinding online poker full-time, keeping detailed records, and relying on those winnings to pay rent — that's a different conversation, and a tax professional's advice is genuinely worth seeking.

One practical note on online play

Online betting and gambling require the use of a credit card or e-commerce account where wagers are withdrawn and winnings are deposited. This means your transaction history at a licensed Ontario casino is inherently traceable — a good reason to stick to operators registered under iGaming Ontario (look for the iGaming Ontario and BetGuard logos on any site you use, which confirm it's operating within the regulated market). Playing on unregistered offshore platforms doesn't change the CRA's analysis of your winnings, but it does expose you to other risks entirely.

All of this applies to adults 19 and older — the legal age for online gambling in Ontario. If you ever feel your play is becoming less recreational and more compulsive, ConnexOntario is available at 1-866-531-2600.

The short version: for a recreational player, frequency alone won't trigger tax on your winnings. The CRA's concern is whether gambling has crossed into a structured, skill-driven business activity — and for the vast majority of Ontario online casino players, it simply hasn't. If your situation is genuinely ambiguous, a Canadian tax professional is the right call; this is a facts-and-circumstances analysis, not a bright-line rule.
