Toronto Pearson Airport experienced flight delays on the night of October 20, 2026, after smoke was reported within the airport’s apron management unit tower. This prompted an evacuation of the facility that controls aircraft movements around gates and loading zones.
Separation of Apron Management and Air Traffic Control Operations
Unlike the air traffic control tower operated by NAV Canada, the apron management unit is managed by the Greater Toronto Airports Authority (GTAA) and functions independently from runway and taxiway control. NAV Canada’s air traffic control tower at Pearson remained operational and was not evacuated during the incident, with communications between pilots and controllers continuing without interruption.
Operations at the
apron management unit resumed after the evacuation. However, an air traffic management initiative was implemented following the resumption, causing delays to both arriving and departing flights at the airport.
Official Responses and Passenger Impact
A NAV Canada spokesperson confirmed that their air traffic control services were unaffected by the smoke incident and that their tower had not been evacuated. Air Canada described the event as a “safety incident” related to the apron management unit under GTAA’s control, which impacted multiple flights and was beyond the airline’s control.
Passengers traveling through Toronto Pearson were advised to verify their flight status directly with their airlines due to
the delays caused by the apron management disruption. The incident affected gates and loading zones surrounding the terminal buildings, slowing the flow of aircraft ground movements.
