Sumary of Study: Canadians have the highest risk of respiratory mortality from wildfire pollution:

  • An international study has found Canadians have the highest relative risk of respiratory mortality resulting from wildfire pollution, with Regina and Saskatoon among the worst hit.
  • Published in The Lancet Planetary Health, this unprecedented multi-city, multi-country collaboration analyzed the impact of short term exposure to air pollution on mortality and assessed the impact of forest fire smoke on mortality by pooling data from 749 individual cities in 43 countries over a 17-year period.
  • We used a chemical transport model to estimate daily wildfire derived fine particulate matter (PM2.5) exposure, and a time series model was used to examine the association between exposure and mortality in each city.
  • Overall, about 0.4 percent of total mortality is attributable to wildfire smoke.
  • It’s not surprising to see the risk of wildfire particle pollution is higher for respiratory mortality than for cardiovascular mortality or all-cause mortality.
  • It’s important to note that 0.32 percent of all annual respiratory mortality events in Canada are due to wildfires.
  • What kind of urgent action can be taken to reduce health risks from the increasing wildfires?
