Did you know...?
You can carpool to work, school, activities or a night out. It's a great way to meet new people and reduce emissions, traffic and noise on the road.
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.
