The GTAA is committed to maintaining clean, pollution free air in our buildings in order to ensure a safe and comfortable environment for our guests and employees. We’ve re-affirmed this commitment during these challenging times and implemented state of the art monitoring to ensure your safety in our buildings. Air quality monitoring processes will be used to determine existing quality of air, evaluate effectiveness of control programs, and to identify areas in which we can continually improve your experience.

We’ve used ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommendations, and Environment Canada methodology regarding air quality, to inform our process, and to ensure your safety and comfort. Air quality components such as 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.
