How do I find a tax professional in Ontario who understands gambling income and can help me file correctly?

Gambling and taxes in Canada sit in genuinely murky territory — the CRA's position is not as simple as "winnings are always tax-free" or "winnings are always taxable," and that ambiguity is exactly why finding the right professional matters.

What the CRA actually says about gambling income

An individual's gambling activities may result in taxable business income or a business loss if those activities constitute a source of income — that is, if the person is carrying on the business of gambling. For most recreational players, lottery winnings of any amount are not reported or taxed, unless the prize can be considered income from employment, a business or property, or a prize for achievement. The tricky part is that the line between "recreational player" and "gambling business" is drawn on a case-by-case basis. Determining the commerciality of gambling can be challenging — games of pure chance, like lotteries, lack the badges of trade to which the traditional tests of business activity can be applied. Factors the CRA looks at include the frequency and systematic nature of your play, your record-keeping habits, and whether you approach it with a profit motive that goes beyond the hope every gambler holds. Profits derived from bookmaking or from the operation of any gambling establishment constitute income from a business — that part is clear-cut. Everything in between requires judgment.

The authoritative CRA document on all of this is Income Tax Folio S3-F9-C1, which covers the tax treatment of gambling winnings and miscellaneous receipts that don't readily fall within the usual categories of income, including prizes from lottery schemes and pool system betting, and indicates whether and under what circumstances a particular type of receipt is included in calculating income. Reading it before you meet a tax professional will make that first conversation much more productive.

Finding someone who actually knows this area

The honest answer is that "gambling income" is a niche. Most general-practice CPAs handle it rarely, and some will give you the oversimplified answer ("it's not taxable in Canada, full stop") without appreciating that your specific situation — volume, frequency, record-keeping, whether you treat it as a business — could put you in different territory. You want someone who has genuinely worked through the business-vs-hobby analysis with gambling clients before.

Your best starting point is CPA Ontario, the provincial regulatory body for Chartered Professional Accountants. CPA Ontario is the regulatory body for Chartered Professional Accountants in Ontario. Their website has a "Find a CPA" directory that lets you search by specialty and location — use it to identify Toronto-area practitioners who list personal tax or self-employed income as a focus area, then ask directly during your initial call whether they've handled gambling-as-business analyses before. That one question will tell you a lot.

Beyond the directory, a few practical filters help narrow the field: look for CPAs or tax lawyers who specifically mention self-employment income, business income determination, or CRA audit representation in their profiles. Those practitioners tend to be fluent in the source-of-income questions that gambling raises. A tax lawyer (found through the Law Society of Ontario's directory at lso.ca) can be worth consulting if your situation is genuinely complex — say, you've been playing at high volume on Ontario's regulated online platforms for several years and have substantial net wins or losses you've never reported.

If you're playing casually on a regulated Ontario site (you can confirm a site is part of the legal market by looking for the iGaming Ontario and BetGuard logos), the tax question is usually straightforward and a good CPA is sufficient. If you're playing at a level where you track sessions, use strategy systems, and think of it as a primary income source, get someone with a tax-litigation background involved early — before CRA raises it, not after.

One practical step worth taking regardless: pull your transaction history from every platform you use. Ontario's regulated operators keep detailed records of deposits, withdrawals, and session activity, and a tax professional will want that documentation to make any kind of income determination. The CRA's own audit guidance notes that for all winnings and losses, the CRA requests documents that support the winnings and losses for all significant amounts. Having those records organized before your first appointment saves time and money.

If gambling has become stressful rather than recreational, ConnexOntario (1-866-531-2600) offers free, confidential support — worth knowing about regardless of where your tax situation lands. And as always, you need to be 19+ to participate in Ontario's regulated online market.
