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. For this reason, we’re monitoring the air quality in Terminals 1 and 3 24 hours a day. This practice allows us to not only determine existing quality of air, but also evaluate the effectiveness of control programs and identify areas where we can continually improve your experience.

A variety of air quality measures are being continuously monitored to help ensure a safe and comfortable experience while at Toronto Pearson.

With this enhancement, we’re also introducing a new portal where you can check our in-terminal air quality at any time. To view our air quality data in real time, visit
