The pollution mixture and chemical composition of wildfire smoke is often different from the pollution emitted by other sources, and these differences may influence toxicity. The toxicity of wildfire smoke also depends on the type of vegetation and burning conditions and may change as the smoke “ages” in the atmosphere. This underscores the need to distinguish the health impacts of wildfire smoke from the impacts of other pollution sources.

Smoke may also reduce attention measured on cognitive tests and increase dementia risk.
Correctly sized portable HEPA filter air cleaners can reduce indoor PM2.5 by as much as 80 per cent. And well-fitting N95 respirators (or comparable respirators designed and certified for occupational use) can reduce PM2.5 exposure when outdoors or in transit. The Air Quality Health Index and smoke forecasts can help Canadians decide when these strategies are needed.

Government and public health agencies can help to offset some of these limitations and ensure more equal protection from smoke by providing accessible and clear messages to the public and establishing clean air shelters in libraries, schools and other public buildings.
Maybe they can, but how often will they?
