Air Quality

An air quality study focuses on monitoring contaminants that might affect the air. This study will help HFR planners protect air quality while building and operating the new railway.

Where are air quality studies taking place?

The 2024 air quality studies will take place along sections of existing railway routes in Ontario, from Twin Elm up to Ottawa and down to Vars, and in Québec near Laval to the 740 highway in Québec City.

Why study air quality?

Air quality can affect human and environmental health. By recording the air quality in a particular area, HFR planners will better understand how the air might change while building and operating the new railway and what is needed to protect the air.
