There were over 100 active forest fires in Quebec as of Friday morning. It's the province's worst wildfire season in recent memory, with over 160 blazes burning at the peak of the crisis earlier this month.

According to Quebec's forest fire fighting agency, SOPFEU, over 900,000 hectares have burned so far, while the seasonal average is around 2,000 hectares.

Most fires have been burning in northern Quebec, forcing evacuations in various municipalities, many of which have since been lifted.
