Wildfire smoke still blankets large parts of southern Ontario, including Toronto, and conditions may not improve until Friday morning.
Environment Canada’s orange air quality warning continues to be in place Thursday, a day after it was first implemented for the smoke that turned the skies in Canada’s largest city orange.
The smoke from the wildfires in northwestern Ontario plummeted Toronto’s air quality to the worst in the world throughout Wednesday morning. Only Detroit was ahead of Toronto early Thursday morning according to IQAir, a Swiss air quality technology company that operates the world’s largest real-time air quality information platform.
At one point Thursday morning, IQAir described Toronto’s air quality as “hazardous.” Environment is forecast improved conditions on Friday, with the smoke beginning to disperse around midnight.
The smoke forced the cancellation of several outdoor events Wednesday, including the FIFA Fan Festival watch party in Toronto and the Rock the Park music festival in London.
There were 136 active wildfires in the northwest region as of 8 p.m. Wednesday, according to data from the Ontario government. Of the fires, 63 are considered to be out of control.
The fires have prompted evacuation orders for several communities, including Armstrong, Lac La Croix First Nation, Whitesand First Nation, Gull Bay First Nation and Lac des Mille Lacs First Nation.
One fast-moving blaze has damaged and destroyed homes and buildings on Namaygoosisagagun First Nation, also known as Collins First Nation, north of Thunder Bay.
Premier Doug Ford has said crews are hard at work fighting the fires, and the province will spare no expense in keeping people safe.
