Air pollution in Canada

Air pollution in Canada is regulated by standards set by the Canadian Council of Ministers of the Environment (CCME), an inter-governmental body of federal, provincial and territorial Ministers responsible for the environment. Air pollution from the United States and to lesser extent Canada; caused by metal smelting, coal-burning for utilities, and vehicle emissions has resulted in acid rain, has severely impacted Canadian waterways, forest growth, and agricultural productivity.[1]

Industry is a significant source of air pollution in Canada.

The CCME has set Canada Wide Standards (CWS).[2][3] These are:

  • CWS for PM2.5 = 30 µg/m3 (24-hour averaging time, by year 2010, based on 98th percentile ambient measurement annually, averaged over 3 consecutive years).
  • CWS for ozone = 65 ppb (8-hour averaging time, by year 2010, achievement is based on the 4th highest measurement annually, averaged over 3 consecutive years).

Note that there is no consequence in Canada to not achieving these standards. In addition, these only apply to jurisdictions with populations greater than 100,000. Further, provinces and territories may set more stringent standards than those set by the CCME.
