Ontario online casinos recorded a new monthly revenue record in May, bringing in CA$326.4 million last month.
According to iGaming Ontario, the collection of Ontario online casinos were up 4% compared to April’s $314.1 million. It was also a 25.6% increase from last May, when the province tallied $259.8 million.
May’s new record unseats the previous best, which occurred in December ($320.7 million).
Lowest Growth Rate for 2026
The online casinos in Canada’s province of Ontario are setting new highs, but the year-over-year growth rates continue to see a decline.
Having been seeing 40%+ growth year-over-year toward the final months of 2025, the province has now been under 30% in three of the five months of 2026. That is despite record $300 million in monthly revenue for four of the five months.
- January 2026: Up $77.9 million (33.7%)
- February 2026: Up $61.7 million (28.8%)
- March 2026: Up $76.8 million (31.8%)
- April 2026: Up $71.3 million (29.4%)
- May 2026: Up $66.6 million (25.6%)
The total revenue growth has also been on a declining rate overall. Those year-over-year gains were over $90 million each month to end 2025, but have now fallen below $70 million with May’s data.
Ontario Making Push to $4 Billion in 2026
In 2025, Ontario online casinos finished with a yearly revenue record of CA$3.15 billion.
That ended up being a 40% improvement from 2024’s previous record of $2.25 billion.
Through the first five months of 2026, Ontario is well on its way to another record.
Sitting at $1.54 billion after May, the 2026 revenue is collectively 29.4% ahead of where revenue was in 2025. Should that percentage hold, it would put Ontario just over $4 billion for the year.
Online Casino Wagers also Set Record
Along with the record amount of revenue, online casino wagers also were at a record amount for Ontario in May. Overall, the province had CA$8.37 billion in wagers last month. That topped the previous best of $8.33 billion in March.
Ontario has now had at least $8.1 billion in wagers in five of the last six months after crossing $8 billion for the first time in December.
- December 2025: $8.27 billion
- January 2026: $8.21 billion
- February 2026: $7.65 billion
- March 2026: $8.33 billion
- April 2026: $8.14 billion
- May 2026: $8.37 billion
