How old do you have to be to open an online casino account in Ontario?

Nineteen. That's the floor — no exceptions for online casino gaming in Ontario, and it applies equally whether you're signing up from Ottawa, Thunder Bay, or anywhere else in the province.

You must be 19 years of age or older to participate in all internet gaming products conducted and managed by iGaming Ontario. The AGCO is equally explicit: individuals under 19 years of age are not eligible to play games on a gaming site. This isn't a soft guideline — it's a hard eligibility requirement baked into the Registrar's Standards for Internet Gaming, the rulebook every registered Ontario operator must follow.

It's worth knowing there's a narrow carve-out that doesn't apply to casino play: an individual who is at least 18 years of age and is accessing the gaming site solely for the purpose of purchasing a lottery ticket can do so. But that exception is specific to lottery tickets only. For slots, table games, live dealer, or sports betting — the line is 19, full stop.

What actually happens at registration

Operators don't just take your word for it. Relevant player information must be collected and validated before a player account is created, and date of birth is among the information gathered upon registration. Beyond that initial check, registered operators will have met rigorous standards of game integrity, fairness, and player protections — including controls preventing underage access. In practice, that usually means identity verification against government-issued ID, and some operators use third-party identity services to cross-reference the details you submit.

If you're ever unsure whether a site is legitimately registered in Ontario's regulated market, look for the iGaming Ontario and BetGuard logos — every internet gaming website offered by a fully registered and approved operator in Ontario will display both logos, which tells you the site is managed by iGaming Ontario and regulated by the AGCO.

One other thing worth knowing: BetGuard is a tool that lets you opt out of all regulated online gambling in Ontario with a single request — useful to know if you ever want a structured break. And if gambling is causing stress for you or someone you know, ConnexOntario (1-866-531-2600) connects you with support.
