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.
