Overall, Canadians enjoy a good level of air quality. But in some urban and industrial areas, air pollution levels sometimes still exceed the recommended national standards. Even where air quality meets the standards, scientific research shows that there are still health effects, especially among vulnerable populations such as children and seniors.
