Ontario Casinos: The Best Casinos in Ontario by Region
Reviewed by Ryan Caldwell, Casino Expert & Editor-in-Chief · Updated November 11, 2026
No Canadian province has more land-based casinos than Ontario. They run from giant resorts in Niagara Falls and Orillia to small slot and table venues up north. This guide explains how casinos in Ontario are run, which venues are biggest, where they all are by region, and what a visit involves, from the 19+ age rule and ID to games and self-exclusion.
The toplist above is for online casinos you can play anywhere in Ontario. Keep reading for land-based venues, or see our main online casino Ontario guide to compare the online sites.
How Casinos in Ontario Are Run
Every land-based casino in Ontario belongs to one provincial system. The Ontario Lottery and Gaming Corporation (OLG) holds the right to conduct and manage casino gaming, and private companies handle the day-to-day running of casinos in regional bundles under long-term deals with OLG. The Alcohol and Gaming Commission of Ontario (AGCO) regulates every venue, from the games on the floor to back-office security.
The main private operators are Great Canadian Entertainment, which runs most casinos in the Greater Toronto Area and eastern Ontario; Gateway Casinos, which runs Casino Rama and many venues in central, western and northern Ontario; Mohegan, which operates the Niagara Falls casinos; and the operator of Caesars Windsor. Names can change after renovations or rebrands, so check the venue’s own website before you go.
Best and Largest Casinos in Ontario
Want the best casino in Ontario for a full day or a weekend away? Four resort-scale venues lead the pack, each with hotels, restaurants and entertainment on top of big gaming floors:
Niagara Falls
Fallsview Casino Resort
One of Canada’s largest casinos, with a hotel, spa, theatre and views of the Falls. Casino Niagara next door has a more casual floor.
Orillia
Casino Rama Resort
A major resort casino on Chippewas of Rama First Nation land, roughly 90 minutes north of Toronto, with a hotel, spa and entertainment centre.
Toronto
Great Canadian Casino Resort Toronto
A large resort casino in Etobicoke next to Woodbine Racetrack, with a hotel, restaurants and a live entertainment venue.
Windsor
Caesars Windsor
A riverside resort casino facing Detroit, with hotel towers, a large event centre and a big table game floor.
Ottawa
Hard Rock Casino Ottawa
The capital’s casino, with slots, table games and a live entertainment venue.
Durham Region
Pickering Casino Resort
A newer casino east of Toronto with modern gaming floors, dining and entertainment.
Ask which is the largest casino in Ontario and you’ll usually get one of two answers: Fallsview Casino Resort or Casino Rama Resort. It depends what you measure, the gaming floor, the hotel or the whole resort. Either one deserves a full day.
Casinos in Ontario by Region
Casinos in Ontario, Canada are spread right across the province, and the best Ontario casinos aren’t all in the south. Most residents live within an hour’s drive of at least one. The list below covers the main venues by region and leaves out smaller slot facilities and charitable gaming centres.
Venue names and services change, especially after renovations, so check hours and facilities with the casino before a long drive.
Casinos in Toronto and the GTA
Downtown Toronto has no casino. The city’s main one is Great Canadian Casino Resort Toronto in Etobicoke, next to Woodbine Racetrack, with Pickering Casino Resort and Casino Ajax further east. All three are an easy drive from most of the GTA. Our Toronto casinos guide covers each venue in detail, including how to get there and what you’ll find.
Niagara Falls Casinos
Niagara Falls is Ontario’s most famous casino destination. Fallsview Casino Resort overlooks the Falls, and Casino Niagara is a short walk from the Clifton Hill strip. Between them, they make the city the province’s most popular casino trip. Our Casino Niagara guide covers both and how to plan a visit.
Ottawa and Eastern Ontario
Ottawa’s casino is Hard Rock Casino Ottawa, south of the city centre. Further west along Highway 401, Great Canadian’s Shorelines casinos serve Peterborough, Belleville and the Thousand Islands. Gatineau, across the river in Quebec, has its own casino with an 18+ age rule. Our Ottawa casino guide covers the capital region.
London, Ontario and the Southwest
Southwestern Ontario has the most casinos spread across it. The London Ontario casino is in the city’s Western Fair District, run by Gateway, and it’s the main casino in London, Ontario for the surrounding area. Further south, Caesars Windsor is the region’s resort casino, and smaller casinos in Point Edward near Sarnia, Chatham, Woodstock, Clinton and Hanover serve their local communities. The Elements Casinos in Brantford, Flamboro, Grand River and Mohawk cover the Hamilton, Brantford and Waterloo area.
Central and Northern Ontario
Casino Rama Resort near Orillia anchors central Ontario, with Great Blue Heron Casino in Port Perry (run by the Mississaugas of Scugog Island First Nation) and Gateway casinos in Innisfil and Wasaga Beach nearby. Up north, casinos in Sudbury, Sault Ste. Marie, Thunder Bay, North Bay and Kenora serve communities spread over huge areas, and are often the main entertainment venue in town.
First Nations Casinos in Ontario
Two of Ontario’s best-known casinos sit on First Nations land. Casino Rama Resort is on Chippewas of Rama First Nation land and feeds into a revenue-sharing arrangement that benefits First Nations communities across Ontario. Great Blue Heron Casino in Port Perry is owned by the Mississaugas of Scugog Island First Nation. Both follow Ontario’s gaming rules, 19+ age requirement included.
