How do I track my wins and losses throughout the year as an online casino player in Canada?

Most players asking this question aren't preparing for an audit — they just want to know whether they're actually ahead or behind, and what they'd need if the CRA ever came knocking. Both are fair things to want clarity on, so here's a practical answer covering the tax reality first, then the actual mechanics of tracking.

The Canadian tax picture for recreational players

Lottery and certain other winnings are non-taxable in Canada. That general rule covers the vast majority of Ontario online casino players — slots, roulette, blackjack, baccarat. If you play for fun and don't depend on gambling as a primary income source, your wins are not reported on your T1 and your losses are not deductible. The CRA draws a meaningful line, though: an individual's gambling activities may result in taxable business income or a business loss if the gambling activities constitute a source of income — that is, carrying on the business of gambling. The factors the CRA looks at include the degree of organization in the pursuit of the activity, the existence of special knowledge or inside information that reduces the element of chance, the player's intention to gamble for profit as a means of gaining a livelihood, and the extent of the gambling activities, including the number and frequency of bets.

The practical upshot: a recreational player grinding slots on a registered Ontario site has nothing to file. A highly organized, full-time poker player operating in a systematic, commercial way might. If you're genuinely uncertain which category you fall into, that's a question for a Canadian tax accountant — the CRA's own folio (S3-F9-C1) is the authoritative starting point, but the line between "hobbyist" and "business" is fact-specific.

What your Ontario casino account already records for you

This is where the regulated Ontario market genuinely helps. Under the AGCO's standards, every licensed operator must maintain an auditable account history. Specifically, there must be an auditable trail covering deposit and withdrawal history, gaming event and transaction history, total monies wagered for a session or period of time, total monies won or lost for a session or period of time, and account balance at the start and end of each session.

In plain terms: log into your account at any registered Ontario site and look for a transaction history, play history, or account statement section. The data is there by regulatory requirement. OLG, as one example, lets players access this directly — players have access to a summary of their transactions including deposit, purchase, and withdrawal history, log-in history, and game play history through their player account, and for more extensive history, players can contact Player Support. Private-market operators registered with iGaming Ontario are held to the same underlying standard.

If you play across multiple operators — which many Ontario players do — you'll need to pull statements from each account separately and consolidate them yourself, since there's no cross-operator summary. A simple spreadsheet tracking monthly deposits, withdrawals, and net balance changes across all accounts does the job cleanly.

Building your own record — what to capture

Even if you're a recreational player with no tax obligation, keeping a year-end summary is smart. If the CRA ever asks about large deposits to your bank account that originated from gambling withdrawals, you'll want documentation. For all winnings and losses, the CRA may request the type and frequency of gaming or betting, minimum, maximum, and average gaming loss or bet, source of funds used to place wagers, frequency of wins versus losses, and minimum, maximum, and average gaming win.

The cleanest approach for an Ontario online player:

• Monthly account exports. Download or screenshot your transaction history from each operator at the end of every month. Most platforms allow this; some require a support request for longer date ranges.
• Net deposit/withdrawal tracking. Your true net result for the year is simply total withdrawals minus total deposits across all accounts. This is more reliable than session-by-session win/loss figures, which can be inconsistently defined across platforms.
• Separate accounts from winnings. Keep gambling funds in a dedicated e-wallet or bank account if possible. It makes the paper trail obvious and prevents confusion with other income.
• Note any large single wins. While not taxable for recreational players, a record of where a large sum came from protects you if it ever shows up in a net-worth audit context.

If you ever find yourself checking these numbers compulsively rather than casually — or if tracking losses starts to feel stressful rather than routine — ConnexOntario (1-866-531-2600) is available around the clock and connects you with gambling support services across the province. Worth knowing it's there.

One final practical note: only play on sites registered in Ontario's regulated market. You can verify any operator through the iGaming Ontario registry, and every legitimate site will display both the iGaming Ontario and BetGuard logos. Offshore, unregistered sites have no obligation to maintain the account records described above — meaning if you ever needed documentation, you'd have nothing to show.
