    Ever wonder what happens when it snows at Toronto Pearson? The GTAA has carefully designed an efficient winter operation, helping to minimize the impact of that frosty weather! In this section, learn about the components that make up our winter plan – from snow removal to our deicing facility.

    Winter Operations

    During inclement winter weather, there is very close coordination and communication between the airport, the airlines and Nav Canada. Together, we work towards the same goal: to make sure the airport continues to move in a safe and efficient manner.

    A number of components make up Toronto Pearson's winter plan. These operations help reduce inconvenience for our guests and maintain safe performance during winter weather.


    Our Central Deicing Facility (CDF)

    What is Deicing?

    Deicing is the application of a heated glycol and water mixture to remove any frozen contamination adhering to critical flight control surfaces on an aircraft.

    What is Anti-icing?

    Anti-icing is a precautionary procedure that provides protection against contamination on aircraft critical surfaces during active weather events.

    Fast Facts

    • We've got the largest CDF in the world!
    • Its six deicing bays can accommodate up to 12 aircraft simultaneously.
    • Deicing and anti-icing are vital in safe and efficient operation of aircraft.
    • Deicing can take two to 19 minutes, depending on the contamination on the aircraft and the weather severity.
    • Our CDF is located close to runways and taxiways, ensuring efficient traffic flow.
    • During active weather events, we use the Hangar Deicing Facility, a separate deicing area to support the CDF activity.

    Snow Removal

    Snow removal is a process that involves many people and vehicles. Toronto Pearson has an established plan, including an inspection process done after snow clearing teams provide condition reports on cleared surfaces.
