In 1995, to meet YYZ’s needs through to 2030, the GTAA proposed to replace YYZ’s Terminal 1-Aeroquay and Terminal 2, home of Air Canada, with a new Terminal 1. The logistical and operational challenges were formidable. All airline and airport operations had to be maintained while demolition of existing obsolete infrastructure occurred and new construction began. Not only was a new terminal planned, but 2 new runways, a massive infield operational and cargo area, a specialized de-icing bay and related taxiways and roadways were to be built and integrated into YYZ’s operation.
