How do Ontario online casinos prevent underage players from accessing real-money games?

Keeping minors out of real-money gambling is one of the most concrete, enforceable parts of Ontario's regulatory framework — and it works on several reinforcing levels, from account creation all the way through to advertising rules.

The legal foundation: who is prohibited from playing

Minors are defined as those under the legal age for gaming in Ontario — 19 years of age for casino gaming and sports betting on igaming sites. An individual under 19 is explicitly listed as a prohibited person who cannot access a gaming site, and operators are legally required to enforce this. The prohibition isn't optional or aspirational — it's a hard outcome the AGCO holds every registered operator accountable for.

Account registration and age verification

Strong identity and age verification processes are a core responsible gambling measure, intended to protect underage consumers and those who have self-excluded from online gambling by preventing them from accessing operator websites. In practice, this means that when a player creates an account, the operator must collect and verify identifying information — including date of birth — before that person can reach any real-money game.

The AGCO's intent is to ensure that an individual's age is verified before they are able to access areas of a website where they are able to play lottery and casino games — specifically those areas accessed once a game has been launched, such as by clicking on a game link. Interestingly, it is not a regulatory requirement for operators to verify age simply for a user to view the various lottery schemes available for play — but the moment real-money access is involved, verification must already be complete.

Players may have only one player account with an operator, which closes off the obvious workaround of creating multiple accounts to bypass a flagged or restricted profile. If the list of prohibited and excluded individuals changes, all registered player information must be re-verified to ensure that all registered players are still eligible to play, and if they are not eligible, they are prohibited from gaming.

Advertising restrictions that cut off the path to minors

Prevention doesn't start at the login screen. Advertising, marketing materials and communications shall not target high-risk, underage or self-excluded persons to participate in lottery schemes, shall not include underage individuals, and shall not knowingly be communicated or sent to high-risk players. The AGCO's standards go further than that broad prohibition: at a minimum, materials must not be based on themes or language intended to appeal primarily to minors, appear on outdoor displays directly adjacent to schools or youth-oriented locations, contain cartoon figures or celebrity endorsers whose primary appeal is to minors, or use individuals who are or appear to be minors to promote gambling.

What being on a regulated site actually means for this

To become fully registered and authorized, operators must meet rigorous standards of game integrity, fairness, and player protections — and their sites must have controls preventing underage access. This isn't self-reported compliance; the AGCO monitors igaming operators and digital game offerings for compliance with regulatory obligations, and where concerns are identified, brings operators back into compliance through progressive sanctions, including warnings, suspensions, monetary penalties, and in the most serious cases, revocations.

A practical way to confirm you're on one of these regulated sites: look for both the iGaming Ontario logo and the BetGuard logo, which all fully authorized Ontario igaming operators display. BetGuard, launched in May 2026, is also Ontario's centralized self-exclusion service — a 19+ adult can use it to exclude from the entire regulated market in a single step, with term options of 6 months, 1 year, 5 years, or a custom period. The full, current list of registered operators is maintained at the iGaming Ontario website.
