Ontario Casinos: The Best Casinos in Ontario by Region
Reviewed by Ryan Caldwell, Casino Expert & Editor-in-Chief · Updated November 10, 2026
Ontario has more land-based casinos than any other Canadian province. They range from huge resort casinos in Niagara Falls and Orillia to local slot and table venues across the north. This guide covers how casinos in Ontario are run, the biggest venues, a region-by-region list, and what to expect on a visit, including the 19+ age rule, ID, games and self-exclusion.
The toplist above covers online casinos you can play from anywhere in Ontario. For land-based venues, read on. Our main online casino Ontario guide compares the online sites.
How Casinos in Ontario Are Run
Every land-based casino in Ontario is part of a single provincial system. The Ontario Lottery and Gaming Corporation (OLG) owns the right to conduct and manage casino gaming, and private companies run the day-to-day operation of casinos in regional groups under long-term agreements with OLG. The Alcohol and Gaming Commission of Ontario (AGCO) regulates every venue, from the games on the floor to the security in the back office.
The main private operators include 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. Brands and names can change when operators renovate or rebrand, so check a venue’s own website before you travel.
Best and Largest Casinos in Ontario
If you are looking for the best casino in Ontario for a full day or weekend out, four resort-scale venues stand above the rest, each with hotels, restaurants and entertainment as well as large gaming floors:
Niagara Falls
Fallsview Casino Resort
One of the largest casinos in Canada, with a hotel, spa, theatre and views over the Falls. The neighbouring Casino Niagara offers a more casual floor nearby.
Orillia
Casino Rama Resort
A major resort casino on Chippewas of Rama First Nation land, about 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 hear one of two names: Fallsview Casino Resort or Casino Rama Resort. Which one comes out on top depends on what you measure, whether that’s the gaming floor, the hotel or the resort as a whole. Plan a full day for either.
Casinos in Ontario by Region
Casinos in Ontario, Canada are spread across the whole province, and the best Ontario casinos are not all in the south — most residents live within an hour’s drive of at least one. This list covers the main venues by region; smaller slot facilities and charitable gaming centres are not included.
Venue names and services change over time, especially after renovations, so confirm hours and facilities with the casino before a long trip.
Casinos in Toronto and the GTA
There is no casino in downtown Toronto. The city’s main casino is Great Canadian Casino Resort Toronto in Etobicoke, beside Woodbine Racetrack, with Pickering Casino Resort and Casino Ajax to the east. All three are within an easy drive of most of the GTA. Our guide to Toronto casinos covers each venue in detail, including how to get there and what each offers.
Niagara Falls Casinos
Niagara Falls is Ontario’s best-known casino destination, with Fallsview Casino Resort overlooking the Falls and Casino Niagara a short walk from the Clifton Hill strip. Together they make the city the most popular casino trip in the province. Our Casino Niagara guide covers both casinos 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 area. Remember that 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 widest spread of casinos in the province. The London Ontario casino sits in the city’s Western Fair District, operated by Gateway, and is the main casino in London, Ontario for the surrounding area. Further south, Caesars Windsor is the region’s resort casino, while smaller casinos in Point Edward near Sarnia, Chatham, Woodstock, Clinton and Hanover serve local communities. The Elements Casinos in Brantford, Flamboro, Grand River and Mohawk cover the Hamilton, Brantford and Waterloo region.
Central and Northern Ontario
Casino Rama Resort near Orillia is the anchor of 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. In the north, casinos in Sudbury, Sault Ste. Marie, Thunder Bay, North Bay and Kenora serve communities across very large areas, often as the main entertainment venue in town.
First Nations Casinos in Ontario
Two of Ontario’s best-known casinos are on First Nations land. Casino Rama Resort is located on Chippewas of Rama First Nation land and contributes to 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, including the 19+ age requirement.

Ontario Casinos vs Online Casinos
