List of the busiest airports in Canada

The following is a list of the busiest airports in Canada. The airports are ranked by passenger traffic and aircraft movements. For each airport, the lists cite the city served by the airport as designated by Transport Canada, not necessarily the municipality where the airport is physically located.

Since 2010, Toronto–Pearson and Vancouver International Airport have been the two busiest airports by both passengers served and aircraft movements. Toronto-Pearson's location within the Golden Horseshoe, most populous metropolitan region of Canada solidifies its top spot amongst all of Canada's airports. Given its advantageous position on the BC Coast, west coast of Canada, Vancouver International has long served as Canada's hub for flights bound for Asia and Oceania.

As one of the closest major North American cities to Europe, Montréal-Trudeau has also seen substantial passenger growth in recent years, now serving over 22 million passengers annually, with nearly 16 million on international flights, making it one of North America's busiest international hubs, in Canada second only to Toronto-Pearson.

Calgary International is the busiest airport in Alberta and the fourth-busiest in Canada by passenger traffic, as the region's petroleum and tourism industries and its proximity to Banff National Park have helped foster growth, and offers nonstop flights to an array of destinations in North and Central America, Europe, and Asia.
