Quick answer
The Toronto Airport transfer between terminals uses the automated LINK Train, a free airside service operating 24 hours a day, seven days a week. Trains depart every three to eight minutes depending on time of day, and the journey between Terminal 1 and Terminal 3 takes approximately eight minutes. All passengers with valid boarding passes can use the service without exiting security or paying a fare.
Toronto Pearson processes more than 50 million passengers annually across two terminals that sit on opposite sides of an active runway. The LINK Train was designed as an airside connector, meaning travelers with connecting flights never leave the secure zone. The automated people mover runs on a dedicated elevated guideway stretching 2.3 kilometers between terminals. Trains arrive at dedicated stations within each terminal's secure area: Terminal 1 passengers board near Gate D, while Terminal 3 travelers find the station past security near Gates A and B. Signage throughout both buildings directs passengers to LINK Train platforms using consistent yellow wayfinding. Passengers transferring between terminals at Toronto Pearson must hold a valid boarding pass for their onward flight. International arrivals making domestic connections or vice versa will clear customs and immigration before accessing the train, as Canada requires all arriving international passengers to process through border control regardless of final destination. Once security screening or customs formalities are complete, the inter-terminal shuttle operates as a simple point-to-point service with no intermediate stops. Service frequency adjusts throughout the day based on terminal traffic patterns. During peak morning and evening departure windows, trains operate every three to four minutes. Overnight service continues at intervals of six to eight minutes, ensuring even red-eye connections maintain reliable transfer options. The system's automation removes concerns about driver shifts or service gaps, and real-time platform displays show the next train's arrival time. The corridor linking Pearson's terminals eliminates the need for landside shuttles or re-clearing security. Passengers with tight connections benefit most from understanding their arrival terminal and locating LINK Train signage immediately after deplaning, as navigating unfamiliar terminal layouts under time pressure creates the primary delay rather than the train journey itself.

Locate the Terminal Link Train station
In Terminal 1, follow yellow signs to the station on Level 1 near Gate D. In Terminal 3, the station sits on the arrivals level between Gates B and C. Many passengers miss the signage in Terminal 3 because it blends with baggage claim directionals.

Ride to your destination terminal

Exit and follow terminal signage
When doors open, proceed directly to your gate, check-in counter, or ground transportation. Terminal 1 passengers exit near U.S. transborder screening; Terminal 3 exits near international departures. Re-clear security if moving between domestic and international zones.
