Ontario iGaming Market Reaches $9.48 Billion in May as Casino Tightens Its Grip

Ontario's regulated online gambling market entered the summer with another month of heavy wagering, but the May figures point to something more important than a headline handle number.

The province's iGaming market is no longer being driven mainly by sportsbook expansion. It is being powered by online casino.

According to iGaming Ontario's May 2026 market performance data, Ontario operators handled about C$9.48 billion in total wagers during the month. Gross gaming revenue was roughly C$413 million, while active player accounts stood at about 1.26 million. The figures cover regulated iGaming operators with trading activity under iGaming Ontario's framework. They do not include OLG's iGaming offering or pari-mutuel horse racing. iGaming Ontario also notes that its monthly data is unaudited and subject to adjustment.

The headline number is impressive. But the structure of the market is more revealing. Casino accounted for almost nine dollars in every ten wagered through Ontario's regulated private iGaming system. Sports betting remains commercially important, especially with the 2026 FIFA World Cup being played partly in Canada, but Ontario's May report confirms that casino has become the province's dominant engine.

The May 2026 numbers

Ontario's regulated iGaming operators recorded approximately the following results. Online casino generated C$8.37 billion in handle and C$326.4 million in revenue, making it the main driver of market growth. Sports betting produced C$972 million in handle and C$81.3 million in revenue, a higher-margin but flatter-volume vertical. Peer-to-peer poker, the smallest regulated vertical, recorded C$134 million in handle and C$5.4 million in revenue. In total, that came to C$9.48 billion in handle and C$413 million in revenue, one of Ontario's strongest monthly results.

The casino figure is the key number. Online casino represented about 88 per cent of total wagering in May. That is not unusual for mature iGaming markets, but it is important for how Ontario should be understood. The public conversation often centres on sports betting. The revenue story increasingly belongs to casino.

This does not mean sports betting is weak. Sports betting produced about C$81.3 million in May revenue from C$972 million in wagers. That implies a stronger hold than online casino, where high-volume slot and table-game play produces enormous handle at thinner margins. But casino's scale is now so large that it dominates the market even with a lower win rate.

Casino is the market's real growth engine

The difference between casino and sports betting is structural.

A sports bettor may place a few wagers around an NHL playoff game, a Blue Jays match, a UFC card or a World Cup fixture. Volume rises and falls with the sports calendar. Online casino works differently. A funded account can generate repeated wagering through slots, live dealer games, blackjack, roulette and instant-win products at any time of day.

That makes casino less dependent on events.

In May, Ontario's casino operators generated about C$8.37 billion in wagers and C$326.4 million in revenue. The scale reflects the mechanics of casino play. Money is recycled quickly. A single deposit can become many spins, hands or rounds. Handle therefore grows far beyond the amount originally deposited by players.

This is why casino handle can look almost inflated to readers unfamiliar with iGaming data. It does not mean players deposited C$8.37 billion in May. It means C$8.37 billion was wagered through regulated casino games.

The distinction matters. Handle measures activity. Revenue measures what operators retain after winnings and eligible deductions.

Sports betting is waiting for the World Cup effect

May was the last full month before the 2026 FIFA World Cup began in June. That makes the sports betting number especially interesting.

Ontario sports betting handle was about C$972 million in May. That is large, but not explosive. The market appears to have moved from early-stage growth into a more mature rhythm. Sports betting is now an established vertical, but it is no longer the only growth story.

The World Cup may test that.

Toronto is one of the host cities for the 2026 tournament, and Canada's role as co-host has brought unusual mainstream attention to soccer betting. Sportsbooks have pushed match odds, player props, bet builders, futures and live markets around the tournament. June and July reporting should show whether a home-hosted World Cup can restart sportsbook growth in Ontario or whether the market has already settled into a casino-led pattern.

That distinction will matter for operators. If the World Cup produces only a temporary lift, sportsbooks will remain acquisition tools while casino remains the profit centre. If it creates a deeper soccer betting audience, Ontario could see a more balanced summer.

Active players remain close to record levels

Ontario recorded roughly 1.26 million active player accounts in May.

That number should be read carefully. It is not the same as unique individuals. A single player can have accounts with multiple operators. Still, the figure shows a large and engaged regulated market.

It also helps explain why Ontario has become the model other provinces are studying. The province has not only legalized private iGaming in theory. It has created a functioning market with sustained consumer activity, monthly reporting and enough scale to attract major international operators.

iGaming Ontario's 2024-25 annual reporting showed the market grew to more than C$82.7 billion in total wagers across iGaming products, with C$2.9 billion in gross gaming revenue for the year. Its broader market update also described continued growth in the third year of operations.

May's figures fit that larger trend. Ontario is not a launch story anymore. It is a maturing regulated market.

What May says about Ontario's model

Ontario's market is important because it remains the only open, competitive regulated iGaming market in Canada.

Other provinces have legal online gambling, but usually through government platforms such as PlayNow, PlayAlberta, Loto-Quebec or Atlantic Lottery. Ontario is different. It allows private operators to compete under a provincial conduct-and-manage structure, overseen by iGaming Ontario and regulated by the Alcohol and Gaming Commission of Ontario.

That structure is now being watched closely by Alberta, which has moved toward its own private regulated iGaming framework, as we detail in why Alberta could become Canada's next major online gambling market.

The May data strengthens the argument that a regulated competitive model can capture significant consumer demand. But it also highlights the policy challenge. If most activity comes from casino, then the market's growth is tied to products that carry higher responsible gambling sensitivity than ordinary sports betting.

For regulators, that is the central tension. Ontario has succeeded commercially. The question is whether it can continue to balance growth, consumer protection and political acceptability.

Why casino dominance matters

Casino dominance changes how the industry should be covered.

Sports betting gets the headlines because it is attached to teams, athletes and major events. Casino gets the revenue because it is always available. That difference affects operators, affiliates, regulators and responsible gambling policy.

For operators, casino strength means retention matters as much as acquisition. The battle is not only to bring players in around a Leafs game or World Cup match. It is to keep them active across slots, live dealer tables and cross-sell products.

For affiliates and media sites, casino dominance means Ontario coverage cannot be sportsbook-only. A serious view of the market must include game suppliers, payment speed, live casino, slots regulation, responsible gambling tools and product design.

For regulators, casino dominance raises harder questions around session length, repeated deposits, bonus structures and player monitoring. A market driven by casino needs a different oversight lens than a market driven by occasional sports bets.

The responsible gambling question

Ontario's growth should not be read only as an industry success story.

A larger market also means greater responsibility. More active accounts, deeper casino engagement and more live products can increase risk for vulnerable players. That is why Ontario's next phase may be defined less by raw growth and more by how well the market manages harm prevention.

iGaming Ontario has already moved from quarterly to monthly reporting, giving the public more regular visibility into handle and revenue. The monthly report is now the main source for market performance data and is updated with the previous calendar month of activity.

That transparency is useful. But public market data is only one layer. The more important question is what operators and regulators do with behavioural risk signals at account level: deposit patterns, session intensity, failed limits, chasing losses and signs of loss of control.

If casino keeps driving Ontario's market, responsible gambling technology will become more central to the province's regulatory credibility.

What to watch next

The next reports matter for three reasons.

First, June will capture the opening phase of the 2026 World Cup. If sports betting is going to break out of its plateau, the tournament should show it.

Second, casino may continue to set records regardless of sports events. That would confirm that Ontario's regulated iGaming market is now structurally casino-led.

Third, active account trends will show whether growth is coming from more users, more spend per account, or heavier activity among the same user base.

Those differences matter. A market growing because more players are moving from offshore to regulated sites is one story. A market growing because existing players are wagering more heavily is another.

Final analysis

Ontario's May 2026 iGaming report shows a market that is large, mature and increasingly shaped by casino.

The C$9.48 billion handle is the headline. The C$413 million revenue figure is the commercial story. But the real signal is the vertical split. Casino now dominates Ontario's regulated iGaming economy, while sports betting waits to see whether the World Cup can deliver a meaningful summer lift.

That makes Ontario both a success case and a warning.

It is a success case because the province has built Canada's most important regulated online gambling market. It has channelled large-scale activity into a legal framework and created a model other provinces are now studying.

It is a warning because the economics of the market are being driven by the most intensive gambling vertical. That places more pressure on responsible gambling systems, advertising standards and operator monitoring.

Ontario is no longer proving that regulated iGaming can work. It is proving what a mature Canadian iGaming market actually looks like.

And that market is a casino market first.

Responsible gambling note: Gambling should be treated as entertainment, not a way to make money. Online casino play can move quickly, so set deposit and time limits before you play, only stake money you can afford to lose, and reach out to provincial support services if gambling stops being fun.
