How Ontario’s market works
Ontario runs an open licensing model: any operator that meets AGCO’s Registrar’s Standards and signs an operating agreement with iGaming Ontario can serve the province. The result is Canada’s deepest legal casino market, with global brands like bet365, FanDuel and BetMGM alongside Canadian-built operators like ToonieBet.
The regulated system gives Ontario players protections grey-market players never had: AGCO oversight, dispute mechanisms, centralized self-exclusion, advertising limits, and operators answerable to a local regulator. The channelization numbers show it worked: 91.1% of Ontario’s online gambling now happens on licensed sites, up from roughly 30% before launch.

Ontario’s advertising standards prohibit public inducement advertising; offers may only be shown once you are on the operator’s own site or logged in. National advertising standards extended a similar approach across Canada in January 2026.
