Wildfire smoke and extreme heat can occur together: Preparing for the combined health effects of a hot, smoky future

Exposure to either wildfire smoke or extreme heat poses a significant threat to health. When they occur together, it may amplify the health risks of exposure.

As wildfires become more frequent and intense, how will persistent smoke exposure affect long‑term health?

As communities are exposed to wildfire smoke more regularly and over longer durations year after year, it is critical to consider what these changing exposure patterns mean for our long-term health.

Wildfire smoke is an increasing threat to Canadians’ health

The notion that wildfire smoke is ‘natural,’ and therefore less harmful than other types of air pollution, is not supported by the evidence. Wildfire smoke has been linked to adverse health effects.
