How do Ontario online casinos verify that a player is not on a self-exclusion list before allowing them to register?

Picture this: someone who enrolled in self-exclusion six months ago decides to try signing up at a newly launched Ontario casino site. What stops them from just filling out the registration form and walking straight in? The answer is a real-time infrastructure check — and it's more robust than most players realize.

BetGuard: the central registry every operator must check

Since May 2026, Ontario has run a centralized self-exclusion system called BetGuard (betguard.ca). BetGuard verifies a player's identity and adds them to its central registry; regulated online gambling websites in Ontario can then match that information and prevent the person from logging into or creating accounts. Critically, each operator checks with BetGuard in real time — if you've signed up, BetGuard lets that operator know you should be blocked.

All igaming operators in Ontario participate in BetGuard. Operators are also required to have their own self-exclusion program that meets the requirements set out in the AGCO's Registrar's Standards for Internet Gaming. So there are actually two layers at work simultaneously: the centralized BetGuard check, and each operator's own internal exclusion list.

What the AGCO's standards actually require at the moment of registration

Operators shall prevent Centrally Self-Excluded Persons from creating new player accounts or accessing existing accounts for as long as they continue to be Centrally Self-Excluded Persons. That obligation isn't passive — the AGCO's standards also address what happens if a person already holds an account and is then added to the registry mid-session: upon receiving confirmation that an individual on their gaming site is a Centrally Self-Excluded Person, operators shall immediately take steps to log that person out of their account.

Speed matters too. iGaming Ontario shall ensure that individuals who register for the Centralized Self-Exclusion Program are added to the Centralized Self-Exclusion Registry as soon as is practicable and no later than one hour after registration. That tight window means the gap between a player self-excluding and every operator being able to act on it is deliberately narrow.

The AGCO's standards also address ongoing account monitoring, not just the sign-up moment: if the list of prohibited and excluded individuals changes, all registered player information shall 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.

How BetGuard confirms who it's dealing with

The identity check on the player's end is thorough. BetGuard uses robust identification that includes government-issued ID validation, facial recognition, and multi-factor identification to make sure you are only making the decision for yourself. That verified identity data is what operators then match against when a new registration attempt comes in. BetGuard only collects the information it needs to match you to accounts you may have on Ontario igaming websites.

One practical detail worth knowing: when you use BetGuard, you opt out of all regulated online gambling websites and apps in Ontario — including any that may launch in the future. A site that opens after your exclusion term starts is still covered automatically.

How to tell you're on a site that actually participates

Every internet gaming website offered by a fully registered and approved operator in Ontario will have iGaming Ontario and BetGuard logos displayed. If you see these logos, you know that the website operations are managed by iGaming Ontario and regulated by the AGCO. If either logo is missing, that's a signal to check the official iGaming Ontario registry before playing — the registry is the authoritative live list of who is and isn't legitimately operating in the province.
