• Environment

    Some see Toronto Pearson as a wide expanse of runways, terminal buildings, and roadways. However, we also see the open space and creek valleys that make up approximately one-third of our airport’s land. The work of our Environmental Services division has three areas of focus:

  • The GTAA takes the obligation to sustainably manage growth very seriously. This includes the continuous improvement of our environmental programs and a commitment to understand our impacts so we can mitigate them.


    Air Quality Monitoring

    The GTAA maintains a permanent air quality monitoring station at the southeast area of the airport property. This station began operation in 1994 and the concentrations measured on site are typical of large urban areas and resemble concentrations measured elsewhere along Highway 401.

    Current Air Quality Study and Human Health Risk Assessment (HHRA)

    In 2013, the GTAA started working with external consultants to better understand how the airport’s emissions affect the health of residents in surrounding communities today, and in the projected future. This project served as an update to studies in previous years.

    In support of the study, the GTAA formed a Community Advisory Committee (CAC) as a mechanism to seek input from industry and community stakeholders. Read the CAC Terms of Reference.


    Electric Vehicles

    One key initiative the GTAA has implemented to help reduce vehicle emissions on Toronto Pearson’s property includes the use of electric vehicles. Charging stations are not only provided for electric fleet vehicles, but also can be found employee parking lots.
