Ontario’s regulated iGaming market set all-time monthly records in both online casino handle and iCasino revenue last month.
Ontario gamblers wagered a total of $8.37bn on online casino gaming in May 2026 alone, yielding $326.4m in gross gaming revenue for operators. Those totals were not only new high marks but also represented year-over-year growth of 20.4% and 25.6%, respectively, from May 2025.
The previous biggest month for Ontario online casino was March 2026 for handle ($8.33bn) and December 2025 for revenue ($320.7m).
In May, online casino wagering made up 88% of all Ontario iGaming handle and 79% of all non-adjusted gross gaming revenue. iGaming Ontario (iGO) does not break down its revenue reports by category of online casino, but slots play was likely the bulk of the online casino activity.
Online casino continues to fuel Ontario iGaming growth
In terms of the overall figures, licensed Ontario operators took $9.48bn in cash wagers in May. That total spend was up 17.5% year over year but slightly below the all-time monthly record of $9.59bn set in March.
Operators won $413.1m in non-adjusted gross gaming revenue from that iGaming activity, the highest monthly total so far in 2026. That NAGGR was 22.2% ahead of May 2025’s pace. After four months of 2026, Ontario’s online casino operators are on pace to make around $4bn in revenue from the vertical for the full calendar year.
The growth in operators’ online casino win comes amid continued changes in the market in recent months, including:
- Canadian online casino, betting, and esports company Rivalry halted all play in Ontario in mid-February
- Mobinc’s Conquestador online casino left the province in April, and Casumo followed shortly thereafter
- Goldrush Gaming Group’s BetNova launched for the first time in April and PENN Entertainment introduced its U.S.-first Hollywood Casino app to the province
As of the time of writing, iGO lists 45 licensed and active iGaming operators running 79 sites in the province, which does not include Ontario Lottery and Gaming (OLG).
iGaming Ontario (iGO) reported there were almost 1.26 million active player accounts last month, which generated an average NAGGR of $329 during the 31-day period.
Ontario sports betting lags behind
In contrast, online and mobile sports betting accounted for $972m in Ontario iGaming handle in May, representing just 10% of total spend. Cash wagering on sports was down 7% from April and was exactly the same as the $972m that was bet on sports in May 2025.
But Ontario’s online sportsbooks – of which there are fewer than online casinos – did better in terms of winnings in May 2026 than in May 2025, collectively making $81.3m in sports betting revenue. That was 13.1% ahead of the $71.9m they took on sports wagering in the same month last year.
When iGO releases its June report in late July, sports betting spending will likely be boosted significantly by the first few weeks of the 2026 FIFA World Cup, which has been a frenzy of betting activity for Ontario sportsbooks.
Peer-to-peer poker remains a mere sliver of the market by handle and revenue, with limited options and play fenced in to within Ontario only. The question of whether or not that can change is currently the subject of a multi-provincial appeal in the Supreme Court of Canada.
