Pearson airport terminal 1 has 58 gates: 101, 103, 105, 107–112, 120, 122, 124, 126, 128, 131–145, 151, 153, 155, 157, 160–163, 164A–164B, 165, 166A–166B, 167–181, 191 and 193.

Measuring over 464,000 square metres (5,000,000 sq ft) as you can see in pearson airport terminal 1 map, pearson airport terminal 1 is the 11th largest airport terminal in the world in terms of floor area. Along with the standard customs facilities, the pearson airport terminal 1 also contains a few customs "B" checkpoints along the international arrivals walkway. Passengers connecting from an international or trans-border arrival to another international (non-U.S.) departure in pearson airport terminal 1 go to one of these checkpoints for passport control and immigration checks and are then directed to Pier F. This alleviates the need to re-check bags and go through security and relieves congestion in the primary customs hall.
