"OTTAWA - Authorities in New York, Toronto and Ottawa on Tuesday warned residents about the health risks from air polluted by smoke from unprecedented early summer wildfires in eastern Canada.

An unusually early and intense start to wildfire season has set Canada on track for its worst-ever year as warm and dry conditions are forecast to persist for months.

There are blazes in nearly all of Canada's 10 provinces and territories, with Quebec the worst impacted due to multiple fires caused by lightning."
