Ontario online casino revenue sets new record as player activity intensifies

iGaming Ontario’s newest market update confirms that May was Ontario’s best month in history for online casino revenue. The province’s regulated casino sites generated $326.4 million in online casino revenue, surpassing the previous record of $320.7 million set in December 2025. iGaming Ontario reported that May was also the second-best overall revenue month since the market opened 49 months ago in April 2022, with total online gambling revenue reaching $413.1 million.

According to the same figures, May’s total online revenue was up 22 per cent year-over-year compared with May 2025, when revenue stood at $338 million. While December remains the top month overall at $425.6 million – a period described as having more attractive sports betting options – May’s numbers show that casino activity alone can now push total revenue close to the market’s historic peak.

Sports betting revenue in May was reported at $81.3 million, down from $86 million in April, indicating that the new benchmark was driven primarily by casino play rather than betting handle. Online poker contributed a smaller share, consistent with prior reports that poker represents about two per cent of Ontario’s regulated online gambling revenue since launch.

iGaming Ontario’s cumulative figures show how casino games have come to define Ontario’s online gambling market. Since the regulated system launched, total online gambling revenue through May has exceeded $12.2 billion, excluding Ontario Lottery and Gaming Corporation’s legacy online numbers. Of this total, nearly $9.2 billion – about 75 per cent – has come from online casinos, with $2.74 billion (22 per cent) attributed to sports betting and $254.5 million (2 per cent) to online poker.

For players in Ontario, these proportions reinforce that casino products are the primary driver of regulated online activity. Slots and table games have been described as leading engagement in the province, and the latest iGaming Ontario data aligns with that broader pattern by showing casino revenue outpacing other verticals. The sustained growth in casino revenue also reflects how quickly players have shifted from unregulated options to provincially supervised platforms, where standards for game integrity and responsible gambling apply.

From a public finance perspective, iGaming Ontario reports that approximately $2.44 billion in tax revenue has been generated over the first 48 months of market operation, representing about 20 per cent of total online gambling revenue. This tax stream is tied directly to regulated play, meaning the record casino month in May contributes not only to operator performance but also to provincial revenues that support wider public priorities.

For Canadian players, the record Ontario casino revenue in May signals a few practical shifts. First, it confirms that the province’s regulated online casino environment is now well-established, with sustained growth across multiple years since April 2022. As more of Ontario’s online gambling activity occurs on regulated sites, players increasingly interact with platforms operating under the Alcohol and Gaming Commission of Ontario’s standards for responsible gambling and game fairness.

Second, the data suggests that casino play is becoming the dominant way many Ontarians engage with online gambling, reducing the relative share of sports betting even as betting remains a significant vertical. For individuals who choose to gamble, that trend means a wider range of casino formats, from slots to live dealer tables, are likely to remain central to product development and promotional focus.

Finally, the reported $2.44 billion in tax revenue collected over 48 months shows how regulated online gambling now forms a material, ongoing contribution to provincial finances. While iGaming Ontario’s figures do not detail how those funds are allocated, they underline the fiscal importance of Ontario’s regulated market and explain why provinces such as Alberta are preparing similar competitive frameworks. For players, the immediate impact is that continued regulatory attention on market integrity and player protections is likely as online casino revenue grows.
