June numbers aren't out yet, but May gave Ontario plenty to talk about. Online casino revenue hit a new all-time high last month, and total wagers came in just below the market's best month ever.
A Market That Keeps Breaking Its Own Records
Ontario's regulated iGaming market closed May 2026 with one of its strongest months on record. According to data published by iGaming Ontario, the market generated C$9.478 billion in total cash wagers during the month, representing a 17% increase over the same period in 2025 and landing as the fourth-highest monthly handle figure since the market launched in April 2022. The all-time monthly record remains C$9.592 billion, set in March 2026.
Online Casino Carries the Market
The story behind May's numbers is largely the story of Ontario online casinos. Online casino games accounted for C$8.371 billion of the total handle, representing an 88% share of all wagering activity and a 3% increase from April.
More significantly, online casinos produced C$326.4 million in gross gaming revenue for the month, a new all-time record and a 4% sequential gain. That figure represented 79% of the market's total non-adjusted gross gaming revenue (NAGGR) of C$413.1 million, itself the second-highest monthly total ever recorded, trailing only December 2025's C$425.6 million.
Sports betting contributed C$972 million in handle (10% of the total), while peer-to-peer poker added C$134 million (1%). On the revenue side, sportsbooks generated C$81.3 million and poker contributed C$5.4 million.
Player Spending Holding Firm
Active player accounts dipped slightly by 1% from April to 1.257 million, but average revenue per active account rose 3% month over month to C$329. That combination of a marginally smaller active base producing higher per-player revenue points to a market maturing well past its early promotional phase.
The province now operates with 46 licensed operators managing 80 gaming websites collectively. Leading operators including FanDuel and DraftKings have leaned heavily into standalone casino products in response to the sustained dominance of iCasino within Ontario's handle mix. For anyone evaluating new casinos in Ontario, the growth of that operator roster reflects a market that remains attractive for new entrants even at four years of age.
What the Revenue Record Signals
For players exploring the highest paying casinos in Ontario, the revenue figures carry a practical implication: licensed operators are competing in an increasingly healthy and well-regulated market, which creates structural incentives to retain players through better products, stronger game libraries, and competitive returns.
The May results reinforce the trajectory iGaming Ontario has maintained since the market's April 2022 launch and arrive alongside the channelization milestone reported earlier this month showing 91.1% of Ontario online gamblers now playing exclusively on regulated platforms.
