About wildfire smoke events
Wildfire emergency
If your community is threatened by an approaching wildfire, your local health or emergency authorities will provide advice to protect your health. Be prepared to evacuate at any time. If told to evacuate, do so immediately. Keep informed about the current wildfire situation.
Some communities across Canada regularly experience wildfire smoke events. This is expected to continue as Canada's changing climate provides ideal conditions for more frequent wildfires and longer wildfire seasons. Wildfire season typically runs from early April to late October.
As wildfires burn through forests and grasslands, they produce smoke. Smoke from wildfires in forests and grasslands can be a major source of air pollution for people in Canada.
Wildfire smoke may be carried thousands of kilometres from the fire zone. This means smoke can impact air quality in areas close to and far from the wildfire.
How to check the air quality during wildfire smoke events
The Air Quality Health Index (AQHI) is a scale from 1 to 10+ designed to help you understand what the air quality around you means to your health. The higher the number, the greater the health risk associated with the air quality.
Environment and Climate Change Canada (ECCC) continually updates and reports air quality conditions and the AQHI in many locations. In addition, ECCC issues air quality alerts in communities impacted by wildfire smoke.
During wildfire smoke events, pay attention to:
- the AQHI
- InfoSmog
- air quality alerts
This information can be found on:
- Canadian weather
- the WeatherCAN app
- local weather forecasts
The AQHI and air quality alerts provide messaging and suggestions for both the general public and those more at-risk from wildfire smoke on ways to protect health.
These will help you decide whether you should take measures to protect your health and the health of others in your care. This may include modifying your outdoor activities or travel plans.
