Hundreds of wildfires are burning across Canada, many of them out of control, have blanketed cities in a thick haze of smoke, amid warnings from experts the situation will continue to worsen.

Toronto has long been known as “the Big Smoke” for its history of heavy industry, but the nickname that took on a different meaning Wednesday when residents donned masks outside, following alerts from officials that the city’s air quality would continue to deteriorate. Outdoor school events were delayed and city officials warned vulnerable groups to remain inside when possible.
