On October 21, 2026, Toronto Pearson International Airport experienced flight delays caused by the evacuation of its apron management tower due to smoke reports. The evacuation disrupted arrivals and departures by affecting the management of aircraft at terminal gates and loading zones.
Distinction between Apron Management and Air Traffic Control
The apron management unit, responsible for coordinating aircraft traffic at the gates and around the terminal area, is operated by the Greater Toronto Airports Authority (GTAA). This unit was evacuated because of smoke reports. However, the air traffic control tower at Pearson, managed by NAV Canada and responsible for controlling aircraft on runways and taxiways, was not evacuated
and continued normal operations. Communications between pilots and NAV Canada controllers remained unaffected throughout the incident, confirmed by NAV Canada spokesperson Gabriel Bourget.
Operational Impact and Response
Following the evacuation, Toronto Pearson implemented an air traffic management initiative that affected the scheduling of arriving and departing flights. Delays occurred as airport staff adjusted operations to maintain safety protocols. After the evacuation, GTAA personnel returned to the apron management unit and resumed their duties. The disruption impacted multiple flights as the airport worked to normalize flow through gate and apron areas.
Official Statements from NAV Canada and Air Canada
Gabriel Bourget of NAV Canada confirmed that their air traffic control tower remained fully
operational and pilot communications were uninterrupted. Air Canada described the situation as a “safety incident” involving the GTAA-apron management unit that affected several of its flights. The airline indicated the issue was outside of its control but noted efforts were underway to minimize delays.
Passenger Advisory
Toronto Pearson International Airport urged passengers to verify the status of their flights directly with their respective airlines amid the ongoing operational adjustments caused by the apron management tower evacuation.
