Where to stay and play in Ontario
Last revision · fact check
Ontario leads the country on casino hotels, and on variety: falls-view towers in Niagara, a riverside resort opposite Detroit, a 2023 complex next to Woodbine in Toronto, an adults-only Hard Rock in Ottawa and a lakeland resort outside Orillia. OLG runs every casino in the province, the AGCO regulates them, and entry is 19+.

5 casino hotels in our guide
Fallsview Casino Resort
Ask Canadians to name a casino hotel and most will say Fallsview. It earns that with 372 guest rooms aimed at the falls, over 3,200 slots and 110 tables, a pair of theatres (the bigger one seats 5,000) and 20-plus restaurants. Nowhere else in the country fits this much under one roof — let alone with Niagara outside the window.
Caesars Windsor
Biggest hotel in our guide, full stop: 758 rooms in two towers, most looking over the Detroit River at the Detroit skyline. Then there's the Colosseum — 5,000 seats, none more than 225 feet out — and a floor with 2,000-plus slots and 80-plus tables, right downtown instead of out by a highway exit.
Great Canadian Casino Resort Toronto
Opened in 2023 beside Woodbine Racetrack, Great Canadian Toronto is the GTA's newest large-scale casino resort — 400 rooms, a theatre for 5,000, a pool with sauna and steam, no-charge parking and a free Pearson shuttle. The operator says no Canadian casino carries more slot machines.
Casino Rama Resort
Casino Rama, on Rama First Nation land near Orillia, is midway through its most significant upgrade in years — rooms redone from 2025, a fresh ground-floor spa, and three new restaurants including Gateway's Atlas Steak and Fish. The 5,000-plus-seat Entertainment Centre keeps headliners driving up the 400.
Hard Rock Hotel & Casino Ottawa
The newest casino hotel in this guide opened on July 3, 2025, as Canada's first fully integrated Hard Rock resort. Inside: 150 rooms including 22 suites, a 24/7 casino with 1,500-plus slots, Council Oak steaks and Hard Rock LIVE (capacity 2,200). It's 19+ throughout — hotel, restaurants, everything.
