Smoke from wildfires burning in the Prairies is affecting air quality in Quebec, with Environment and Climate Change Canada warning of increased health risks associated with exposure to fine particulates in the air.

Almost the entire country, including Montreal, is under an Environment Canada air quality warning or special weather statement on Friday, as wildfires continue to rage across the Prairies causing poor air quality and reduced visibility.

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.
