Wildfire Smoke and Health

Topics: Air, Forest Fires, Outdoor Air

The frequency and intensity of Canadian wildfires is increasing as a consequence of the changing global climate, as well as long-standing forest management practices (Flannigan et al., 2013). Fires pose a direct threat to lives and properties in some communities, and also cause episodes of extreme smoke pollution that threaten the health of populations over large geographic areas.

  • Wildfire smoke is a complex blend of gasses and particles, including heavy metals; smoke exposure has been associated with a wide range of acute health effects, from increased reporting of respiratory and cardiac symptoms through to increased risk of mortality. (Finlay et al., 2012)
  • The most recent estimate of premature deaths worldwide due to wildfire smoke was 339,000 annually over the period of 1997 to 2006. (Johnston et al., 2012)
  • Some populations are more susceptible to these effects, including: those suffering from respiratory or cardiovascular disease; pregnant women; infants and young children; the elderly; and those of low socioeconomic status. (Reid et al., 2016; Liu, 2015)
  • A report published by the Canadian Council of Forest Ministers (CCFM) found that the number of fires occurring at the wildland-urban interface is increasing and the damages are likely compounded due to climate change. (CCFM, 2013)

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.

  • Upcoming: Responding to Wildfire Smoke Events: Role of Public Health, Perceptions and Challenges (March 2018)
    This Health Canada-funded project will look at public health preparedness and response to wildfire smoke events in three Canadian jurisdictions, with the aim of understanding practitioners needs and challenges.
