Methods and Sources 

1 The health risk level represents a summarized value from purple air monitors which measure Particulate Matter. The recommendations are from the Air Quality Health Index (AQHI) scale, which uses a combination of particulate matter (PM2.5), ozone and nitrogen dioxide, however, only data on particulate matter is available for our health unit area. For more details on real-time weather alerts, visit Environment Canada.

   These monitors were provided by Environment and Climate Change Canada and are generously hosted and maintained by various community partners.
