ATC returning to Mirabel in January

Effective Jan. 30, 2020, air traffic controllers will once again be working at Montreal International (Mirabel) Airport (CYMX).

Following the completion of a recent aeronautical study, Nav Canada has decided to reinstate air traffic control (ATC) services at the airport for 16 hours a day, from 1100 to 0300 Coordinated Universal Time (1000 to 0200 UTC during daylight savings time) using the current mandatory frequency 119.1 MHz. While the tower is in operation, the control zone and terminal control area will become Class C airspace.

When ATC is closed, the Flight Service Station (FSS) will operate and the airspace will revert to Class E and transponder airspace.

Nav Canada said ground control service during ATC operating hours and ground advisory service during FSS operating hours will be provided on VHF frequency 121.8 MHz.

Mirabel saw over 69,000 movements in 2017 and exceeded 75,000 in 2018.
