Toronto Pearson International Airport, or Toronto Pearson (IATA: YYZ, ICAO: CYYZ), is located 27 kilometres (17 mi) northwest of downtown Toronto by road, in Mississauga, Ontario, and is Canada's busiest airport.

If you have not been to Toronto Pearson since January 2007 you will notice some major changes: The old square Terminal 1 has been replaced, Terminal 2 is no longer used for passenger services, and Terminal 3 has had some major upgrades.
