Province guide
Ontario's casino hotels, reviewed
Last updated · facts verified
Ontario leads the country on casino hotels, both in number and in variety. Pick from towers above Niagara's falls, a riverfront complex looking at Detroit, a 2023 build next to Toronto's racetrack, Ottawa's 19+ Hard Rock or a lakeside resort near Orillia. All of them run under OLG, the AGCO regulates them, and the door age is 19.

5 casino hotels reviewed here
Fallsview Casino Resort
Fallsview is the name most Canadians reach for, and the numbers explain why: 372 rooms planned around the falls, a floor of 3,200-odd slots and 110 tables, two theatres led by the 5,000-seat OLG Stage, and 20-plus places to eat. Nowhere else in Canada stacks that much behind one front door — or gives it that view.
Caesars Windsor
Caesars Windsor is the giant of this guide: 758 rooms in two towers, most of them pointed at Detroit's skyline across the river. Add the Colosseum (5,000 seats, none over 225 ft from the stage), a floor of 2,000-plus slots and 80-plus tables, and a downtown address instead of a highway exit.
Great Canadian Casino Resort Toronto
The operator's boast is simple — more slot machines to choose from than anywhere in Canada. Around them, beside Woodbine Racetrack since 2023: a 400-room hotel, a theatre holding up to 5,000, sauna and steam room by the pool, a garage where parking costs nothing and a complimentary shuttle from Pearson. It's the Toronto area's newest big casino resort.
Casino Rama Resort
Headliners at a 5,000-plus-seat Entertainment Centre are still what pull crowds up the 400 to Casino Rama, on Rama First Nation land outside Orillia. What's changed is everything around the stage: rooms under renovation since 2025, a spa newly built at ground level, and three restaurant openings — Gateway's Atlas Steak and Fish the most notable.
Hard Rock Hotel & Casino Ottawa
Opened on 3 July 2025, Hard Rock Ottawa is the youngest casino hotel in this guide and the first fully integrated Hard Rock resort in Canada. Inside: 150 rooms (22 suites), a never-closing casino with 1,500-plus slots, Council Oak steakhouse and Hard Rock LIVE for up to 2,200. Every inch of it, hotel included, is 19+.
