Did you know...?
Even if you are relatively fit and healthy, you could experience symptoms when exercising or working outdoors if pollution levels are higher than usual.
The AQHI is an initiative between Environment Canada, Health Canada, the Department of Environment and Climate Change, and the Department of Health and Community Services of Newfoundland and Labrador.
