The Biggest Casinos in Canada, Ranked by Gaming Floor: Toronto Is First at 328,000 Square Feet, and the Number Everyone Quotes for Montréal Has No Source

Only a handful of Canadian casinos publish the size of their gaming floor, and the one most often called the biggest is not among them. A ranking built from operators' own figures, with the date of each, and a second one by slot machines for the casinos that will not say.

Published 2026-11-10.

The casino usually named instead, Casino de Montréal, appears across the web at 526,488 square feet. Loto-Québec, which owns it, publishes no floor area on its casino site, and there is none in the 140 pages of its 2025-26 annual report. This ranking uses figures the operators have put their names to, says how old each one is, and keeps the rest in a separate pile.

Toronto's lead is not close. Great Canadian's opening release called it "the newest and largest casino resort in Canada," and in September 2024 the company was still using the 328,000 figure while adding a high-limit slot room with more than 220 machines and 26 high-limit tables. The resort has a 400-room hotel and a 5,000-person theater. What the operator has not done since 2023 is publish a new total for slots or tables, and its site today shows none, so the 4,800 and the 145 are opening-day numbers.

If 526,488 square feet were the gaming floor of Casino de Montréal, it would be first by a wide margin. The figure appears on World Casino Directory, in Wikipedia without a citation, and in a great many lists that copied one or the other. We could not find it in anything Loto-Québec has published.

What Loto-Québec does say is that the casino has gaming on five floors, that it is among the largest in the world, and that it has "over 2,800" slot machines. It gives no table count; older figures of 3,000 machines and 80 tables trace to pages from 2011. Put the web's floor figure next to the owner's slot count and the casino would have a floor 60 percent bigger than Toronto's with roughly 40 percent fewer machines on it. That reads like the area of a building, not of a gaming floor, and until Loto-Québec says otherwise we are not ranking on it.

None of this makes Montréal small. By machines it is third in the country, and it is open to 18-year-olds. It has no hotel; the corporation's annual report lists one next door as a project still under way. But "biggest casino in Canada" is a claim we could not find its owner making, and the operator that does make it has a number attached.

Two more figures stay out of the table for the same reason. Casino Rama is given 192,000 square feet by Wikipedia, uncited, which would put it third. Gateway, which runs it, publishes no floor area, and its own pages disagree about the rest: the properties page, stamped August 2026, says more than 1,600 slots and 43 tables, while the company's home page still says more than 2,200 and more than 85. The 80,000 square feet attributed to the Coquitlam casino our directory still lists as Hard Rock Casino Vancouver comes from a 2013 news report. It dropped the Hard Rock name in 2023, and Great Canadian sold it to the Snuneymuxw First Nation's Petroglyph Development Group on May 5, 2026.

Most Canadian casinos will tell you how many machines they have and nothing about square feet, so this is the ranking that reaches past Ontario.

The usual way to use a list like this is to pick the top name and go. For most trips that is a mistake, and the data above shows why.

Square footage measures how far you walk. Tables and machines measure whether there is a seat. Fallsview has about 60 percent of Toronto's floor and, by its own count, about two thirds of the tables, in a building with a view Toronto's does not have. Windsor is less than a third of Toronto's size and is the only casino in Canada that earns Caesars Rewards, which matters more to a Detroit player than any floor plan. Montréal lets an 18-year-old in and Ontario does not. Our Ontario guide sorts that province's 30 casinos by who runs them, and the province-by-province count covers the rest.

Size also tells you nothing about what is open on the day. Security officers at the Toronto resort have been locked out since July 23, 2026, and the operator's update page on November 9 was still warning that cars were being let through the picket line every three minutes. The biggest casino in Canada is open around the clock and takes longer to get into than the second biggest.

For a first visit from the United States the ranking we would use is by border, not by floor: Fallsview from Buffalo, Windsor from Detroit, Montréal from Vermont or northern New York, River Rock from Seattle. Our Canada directory lists them all, and every one of them pays in Canadian dollars.
