Air quality assessment and initiatives

Air quality monitoring

Since 1994, we have maintained a permanent air quality monitoring station at the southeast area of the airport property. The concentrations measured at the monitoring station are typical of large urban areas and are similar to the concentrations elsewhere along Highway 401.

Recent studies: Air Quality 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 as part of the study.

Electric Vehicles

One of our key initiatives to help reduce vehicle emissions on Toronto Pearson’s property is the use of electric vehicles. We have charging stations for our electric fleet vehicles, and also in our employee parking lots.

Indoor Air Quality

We are committed to maintaining clean, pollution free air inside our buildings to ensure a healthier environment for passengers and employees. New air quality monitors have been installed in Terminals 1 and 3, which will be used to determine existing quality of air, evaluate the effectiveness of control programs and identify areas where we can continually improve your experience.

Our monitoring is based on American Society of Heating, Refrigerating and Air-Conditioning Engineers recommendations and we’ve aligned our air quality index with Environment Canada methodology. Fine particulate matter (PM 2.5), nitrogen dioxide, ozone, carbon monoxide, temperature and relative humidity are being continuously monitored to help ensure a safe and comfortable experience while at Toronto Pearson.
