The Air Quality Health Index is Canada's scale for the health risk of the air around you. Environment and Climate Change Canada publishes it, from a mixture of ground-level ozone, fine particulate matter (PM2.5) and nitrogen dioxide.
Places sit at their approximate centres. Lake Ontario's shore is simplified. Each pin links to that city.
