Ontario casino hotels, reviewed
Last updated · facts verified
Ontario leads the country on casino hotels, in number and in variety: towers over the falls at Niagara, a riverfront resort facing Detroit, a new-build next to Toronto's racetrack, an adults-only Hard Rock in Ottawa and a lake-country resort outside Orillia. OLG runs gaming, the AGCO regulates it, and 19 is the age to play.

Reviewed here: 5 casino hotels
Fallsview Casino Resort
Say "casino hotel" to most Canadians and Fallsview is the picture that comes to mind — with reason. The tally: 372 rooms angled at the falls, 3,200-plus slot machines and 110 tables downstairs, two theatres (the big one, OLG Stage, seats 5,000) and 20-plus restaurants. Nowhere else in Canada fits that much under one roof with that view out the window.
Caesars Windsor
758 rooms — more than anywhere else in this guide — split over two towers, most of them pointed at the Detroit skyline across the river. Downstairs: 2,000-plus slot machines and 80-plus tables. Next door: the 5,000-seat Colosseum, whose farthest seat is 225 feet from the stage. And all of it downtown, not off a highway ramp.
Great Canadian Casino Resort Toronto
Next to Woodbine Racetrack, the youngest of the Toronto area's big casino resorts — a full resort only since 2023. It brings 400 rooms, a theatre holding up to 5,000, a pool with sauna and steam room, no-charge parking and a free Pearson shuttle; the operator adds that no Canadian casino offers more slot machines to choose from.
Casino Rama Resort
The biggest overhaul Casino Rama has seen in years is well under way on its Rama First Nation site near Orillia: rooms renovated since 2025, a ground-floor spa, three new restaurants led by Gateway's Atlas Steak and Fish. The constant is the 5,000-seat Entertainment Centre, still pulling major acts up the 400.
Hard Rock Hotel & Casino Ottawa
Youngest property in the guide (opened July 3, 2025) and the first fully integrated Hard Rock resort in Canada. Inside: 150 rooms including 22 suites, a casino that never closes with 1,500-plus slot machines, a Council Oak steakhouse, and Hard Rock LIVE holding up to 2,200. Age 19 and over only — and that covers the beds.
