Toronto Pearson Flights Delayed After Apron Management Tower Evacuated Over Smoke Reports
Why It MattersThe incident shows how ground-side apron management, run separately from air traffic control, can disrupt a major hub's flow of arrivals and departures without any loss of controller communications.
Flights to and from Toronto Pearson airport faced delays Tuesday night after reports of smoke prompted the evacuation of the airport's apron management unit tower, which manages the flow of aircraft traffic at gates and loading zones. In a post on X, Toronto Pearson said staff had since returned and resumed operations, but an air traffic management initiative was in effect, causing delays to arriving and departing flights. The airport urged passengers to check their flight status directly with their airlines.

NAV Canada spokesperson Gabriel Bourget said in an email Tuesday night that NAV Canada's air traffic control tower at Pearson was not evacuated and continued to operate normally, and that communications between pilots and NAV Canada controllers were not affected. He said the apron management unit is operated by the Greater Toronto Airports Authority (GTAA). NAV Canada controllers manage the safe movement of aircraft in the air and on runways and taxiways, while the GTAA manages the areas around the terminal buildings and gates.
In a notice to passengers on affected flights, Air Canada described the situation as a "safety incident" involving the GTAA and its apron management unit, said it was impacting multiple flights and was outside Air Canada's control, and said its teams were working to minimize delays.
