Ontario casino stays: five hotels, one province, 19 to play
Checked against sources · page revised
Most of Canada's casino hotels are in Ontario, and they differ wildly: towers above the falls in Niagara, a riverfront resort facing Detroit in Windsor, a 2023 build at the Toronto racetrack, an all-19+ Hard Rock in Ottawa, and lake country outside Orillia. Every casino here runs under OLG with AGCO regulation; the entry age is 19.
Niagara's big one, and our first choice. Plan on 372 rooms built around the view, a 200,000-sq-ft floor below them, two stages (5,000 seats and 1,559) and more than 20 places to eat. No other Canadian casino resort puts a waterfall outside the window at this size.
Book it forA two-night stay where you never move the car: view, show and tables all inside.
Skip it ifYou travel for buffets (none right now) or want under-12s in the pool unsupervised.
Toronto's newest big casino hotel, by Woodbine Racetrack since 2023. Count four hundred rooms, a theatre that takes five thousand, sauna and steam beside the pool, and what the operator calls the widest slot choice in Canada. Free: parking and the Pearson shuttle.
Book it forFly-in weekends, a 5,000-seat concert, and slot players chasing the biggest selection in the country.
Skip it ifYou need space (standard rooms are 388 sq ft) or a view beyond the racetrack and the suburbs.
The biggest hotel on our list — 758 rooms in two towers, most looking straight across the river at Detroit. Downstairs: the 5,000-seat Colosseum (no seat past 225 feet) and a floor of 80-plus tables and over 2,000 slots. You stay downtown, not out by a highway exit.
Book it forArena concerts, a downtown weekend on the river, and anyone who wants a wide choice of rooms.
Skip it ifYour children want the pool. They can't use it: adults only.
Our newest stay sheet: Hard Rock opened in Ottawa on July 3, 2025 — in its words, a first fully integrated Hard Rock resort for Canada. One hundred and fifty rooms (22 suites), a Council Oak steakhouse, a concert hall for 2,200 and a 24-hour floor of 1,500-plus slots. Nobody under 19 gets past the lobby.
Book it forGrown-ups after a steak, a gig and tables that never close.
Skip it ifAnyone travelling with you is 18 or younger. They can't even check in.
Near Orillia, on Rama First Nation land, a resort in the middle of a refit: rooms being redone since 2025, a new spa at ground level and three new places to eat, led by Atlas Steak and Fish. The draw is still the Entertainment Centre, 5,000-plus seats, which keeps big names coming north.
Book it forA concert road trip from the GTA, or a lake-country weekend that includes the tables.
Skip it ifYou don't have a car. Toronto is roughly two hours away by road and we found no transit plan.
Full write-ups are still to come for two more Ontario hotels. East of Toronto, Pickering Casino Resort opened its 275-room hotel in January 2023. Near Port Perry, Great Blue Heron Casino & Hotel finished its hotel in November 2021. For now both appear on our new openings page.
