Toronto Lester B. Pearson International Airport

Toronto Pearson is Canada's largest airport by any measure — passengers, aircraft movements, cargo tonnage, and international destinations — and consistently ranks among the top ten airports in North America. It serves 100 airlines on 544 routes reaching 236 nonstop destinations, and handles more trans-border traffic to the United States than any non-U.S. airport. The facility occupies 4,600 acres (1,862 ha) in Mississauga, roughly 22 km (14 mi) northwest of downtown Toronto. Air Canada operates its main global hub here, running a full trans-atlantic, trans-pacific, and Latin American long-haul program alongside the densest single-carrier North American network outside Chicago or Atlanta. WestJet maintains a significant base. YYZ is one of the few airports outside the United States with U.S. Customs and Border Protection preclearance facilities, meaning U.S.-bound passengers clear American immigration before boarding — a feature that materially increases the value of the hub for onward U.S. connections. Five runways arranged in two widely-spaced parallel pairs plus one crosswind support simultaneous triple arrivals, a configuration rare outside the largest U.S. hubs. Two terminals operate today: Terminal 1 is among the largest single airport terminals in the world at 5.7M sq ft (530,000 sq m), housing Air Canada and most Star Alliance carriers; Terminal 3 serves Oneworld, SkyTeam, and the low-cost segment. The LINK Train automated people-mover connects the terminals with the Viscount rental-car and long-term parking complex 24/7.
