Which city in Canada has the biggest airport?

Toronto Pearson International Airport (YYZ) As Canada's largest and busiest airport, Toronto Pearson International Airport sees nearly 50 million passengers annually.



The answer depends on whether you mean "biggest" by land area or by passenger volume. In 2026, Toronto holds the title for the "biggest" airport by passenger traffic and aircraft movements. Toronto Pearson International Airport (YYZ) serves over 46 million passengers annually and is the primary international hub for Canada. However, if you are measuring by physical land area, the title goes to Montreal. The Montréal–Mirabel International Airport (YMX) occupies a staggering 17,000 acres, making it the largest airport in Canada by size (and one of the largest in the world). Interestingly, Mirabel no longer handles commercial passenger flights—having shifted to cargo and manufacturing—leaving the 7,000-acre Edmonton International Airport (YEG) as the largest operating passenger airport by land area. Following Edmonton is Calgary International Airport (YYC) at 5,144 acres. So, for travelers, Toronto is the busiest and most significant, but for sheer geographic footprint, Montreal and Edmonton lead the nation.
