The single most important check before you sign up anywhere is licensing. In Ontario, a legitimate operator needs two things: an active AGCO registration and an iGaming Ontario (iGO) Operating Agreement. Having one without the other is not enough — some operators are AGCO-approved but not yet live on the iGO directory, meaning they cannot legally take an Ontario bet yet.
You can verify any operator directly at igamingontario.ca/en/operator/operators. Licensed sites are also required to display iGaming Ontario branding, usually in the footer, alongside a clear 19+ age statement.
Beyond licensing, look for: a working customer support channel (live chat is standard), clear withdrawal timelines stated on the site, and dedicated self-exclusion tools (BetGuard covers every iGO-regulated site through one portal). If a site is missing any of these, that is a red flag regardless of how polished the design looks.
Be especially cautious of sites using a familiar global brand name but running on a different, non-Ontario domain — many international brands operate a separate .ca or “on.” prefixed site specifically for Ontario. Landing on the wrong version means you have no Ontario player protections at all.
