Wildfire Smoke and Health
The frequency and intensity of Canadian wildfires is increasing due to the changing global climate, as well as long-standing forest management practices. Ever-worsening fire seasons impact communities in a variety of ways, including through smoke exposure and the threat of property damage, evacuation, and loss of life. The resources assembled here are intended to assist public health practitioners, decision-makers, and the public by providing guidance regarding public health impacts, community preparedness, risk communication and response to wildfires and wildfire smoke.
