What terminal is WestJet Airlines at YYZ? WestJet Airlines operates mostly from Terminal 3 at Toronto Pearson International Airport (YYZ). This terminal serves both domestic and international flights for WestJet, and customers may access check-in counters, baggage claim, security, and other airline facilities. However, because terminal assignments might vary, customers should always double-check their terminal and gate information closer to their departure time, either on the WestJet website or on their boarding card.
