Why Ontario is different
Since April 2022, Ontario players have been able to play at operators licensed by iGaming Ontario and the AGCO. That means stronger player protection, local dispute resolution and responsible-gambling tools built in. Regulated apps must meet these standards, so you get accountability you simply don’t have with unregulated offshore sites. Learn more in our Ontario betting guide and our overview of the best online casinos in Canada.
App or mobile browser?
Many Ontario casinos work perfectly in your phone browser with no download, while others offer native iOS and Android apps. Both give you the full game library; the choice comes down to convenience.
