• Noise Advisories from the Noise Management Office

    The Toronto Pearson Noise Management Office periodically publishes advisories and notices for resident awareness of airfield construction, airport activities, and engagement opportunities that could have an impact on normal airport traffic operations and aircraft noise impacts on the community. Please check this page regularly for updates.

    Spring 06L/24R Runway Resurfacing

    Resurfacing work on one of Canada’s busiest runways (06L/24R) is planned to begin as early as April 23, 2018. This project will consist of electrical work and the milling and resurfacing of runway 06L/24R to keep the surface in top condition and ensure continued safe operations. Learn more.

    NAV Canada Flight Inspections

    NAV Canada

    Have you noticed a small blue and white aircraft flying low and circling around Toronto Pearson? This is likely NAV Canada conducting routine flight inspections on the Instrument Landing Systems (ILS).

    ILS are electronic navigational aids that help guide pilots to the airport’s runways. As regulated by Transport Canada, the ILS systems at Toronto Pearson must be inspected every four months to ensure accuracy, with longer annual tests to ensure the equipment is certified for use. If significant work is conducted on an ILS, a flight inspection must be conducted to ensure system verification.

    The inspections usually last between 30 minutes and 5 hours. We appreciate your patience.

    Routine Maintenance

    At Toronto Pearson we spend a lot of time making sure that the airfield at Canada’s largest airport is kept in tip-top condition. We use a program of regularly scheduled maintenance to do this. All our runways get equal attention to keep them open and we work hard to minimize the impact of that maintenance on our operations and our neighbours. Learn more.

    Runway Assignment 

    Runways are assigned based on the following factors: wind direction and wind speed, runway conditions/availability, operational efficiency and time of day. As the prevailing winds are from the west, the most common runway configuration at Toronto Pearson supports a westerly flow, which means arrivals from the east and departures to the west using Runways 23, 24 Left, and 24 Right. The second most common configuration supports an easterly flow - arrivals from the west and departures to the east using Runways 05, 06 Left and 06 Right.

    Although aircraft can use runways that are not directly aligned with the wind direction in calm wind conditions, once the speed of a crosswind reaches a certain threshold, only runways that are aligned with the wind direction are safe for arriving and departing aircraft.

    How does winter weather affect runway usage?

    Friction is reduced in wet or snow covered runway conditions and so the crosswind speed threshold for arriving and departing aircraft is lower than under dry runway conditions. In these conditions there are more “into the wind” runway assignments for arrivals and departures than in drier conditions. Additionally, anti-ice treatment and snow clearing of runways means that a runway can be temporarily unavailable requiring alternate runway assignment.
