Toronto Pearson International Airport (YYZ) is a massive facility covering approximately 4,600 acres (1,867 hectares) of land in Mississauga, Ontario. In 2026, it remains Canada's largest and busiest airport by a significant margin. To put its size in perspective, the airport grounds host five runways, two active public terminals (Terminal 1 and Terminal 3), and an Infield Concourse. Terminal 1 alone is a world-class architectural feat, spanning over 346,000 square meters, while Terminal 3 covers another 178,000 square meters. The airport operates as a "city within a city," featuring more than 80 gates, multiple massive parking garages with over 12,000 spaces, and its own dedicated transit system (the Terminal Link train) to ferry passengers between buildings. Because of its sprawling footprint, Pearson handles over 50 million passengers annually and serves as the primary global hub for Air Canada, connecting the Greater Toronto Area to more than 180 destinations worldwide. Navigating the airport often requires substantial walking, making the internal people-movers essential for travelers.
