Air Canada MCT Terminal The Minimum Connection Time (MCT) at Air Canada's terminals is the shortest time needed to transfer from one flight to another. This varies depending on whether passengers are transferring within the same terminal, between domestic and international flights, or involving U.S. preclearance. At major hubs like Toronto Pearson International Airport, MCT is carefully calculated to ensure seamless transfers while accounting for security checks, customs, and potential delays. Passengers are advised to check their itinerary and ensure they have sufficient time to meet these requirements for a smooth and stress-free travel experience.
