What Terminal is Air Canada? Air Canada Terminal Assignments for Domestic and International Flights Air Canada uses multiple terminals based on the airport and whether the flight is domestic or international. For example, Air Canada flights at Calgary International Airport (YYC) normally depart from Concourse A in the domestic terminal for local flights and Concourse D in the international terminal for flights abroad. In Europe, Air Canada serves from Terminal 2 of London Heathrow Airport (LHR), a major international travel hub. Knowing the terminal ahead of time is critical for efficient navigation, particularly at large, congested airports with multiple gates and terminals.
