Environment Canada has issued special air quality advisories for southern Ontario and some regions of southern Quebec due to smoke which it says has blown in from wildfires burning in Ontario’s northwest.

       The advisories were issued late Monday afternoon and include the cities of Toronto and Ottawa, and they warn that smoke is causing poor air quality and is reducing visibility.
