Air quality alerts are in effect across much of Canada as Prairie wildfires send smoke eastward, blanketing southern Ontario and Quebec. Toronto, Ottawa and Montreal are recording some of the worst air quality ratings in the world.

The predicted levels of ozone in the atmosphere on Wednesday prompted an Air Quality Advisory to be issued by the Michigan Department of Environment, Great Lakes, and Energy.

If outdoor travel is unavoidable, a well-constructed, well-fitting and properly worn respirator-type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce exposure to the fine particles in the smoke. Even though exposure may be reduced, there can still be health risks, officials say.

Smoke from the Canadian wildfires has triggered air quality warnings in several provinces and surrounding U.S. states. As of Friday, June 6, much of southern Ontario and southern Quebec, including Toronto, Ottawa and Montréal, have been placed under special air quality alerts.
