Enveloped in smoke from Ottawa to Toronto

Burning smoke has choked the entire region from Ottawa to Toronto, as Canada deals with one of its worst wildfire seasons on record that is sending haze and smoke throughout the United States' northeast.

As of Wednesday, 414 wildfires were burning in Canada with 239 out of control, keeping 20,183 Canadians out of their homes, Emergency Preparedness Minister Bill Blair said. So far this year, 2,293 wildfires have torched 3.8 million hectares of land.

Environment Canada has issued special air quality advisories for large areas of Ontario and Quebec, warning of high levels of pollution from wildfires burning across both provinces.

It forecasts that western Quebec's poor air quality may persist for a few more days, while eastern Ontario's may improve a bit on Thursday before deteriorating again on Friday.

According to Quebec's forest fire prevention agency, more than 150 forest fires were burning in the province on Tuesday, including more than 110 deemed out of control.

Quebec's fire authority said it cannot bring all the fires burning in the province under control and only between 20 and 30 fires can be battled at a time until reinforcement arrives.

Armed forces and firefighters from outside the province started arriving on Saturday to help firefighters. About 100 soldiers are on the ground and 550 more firefighters were on the way.

French President Emmanuel Macron tweeted on Sunday that France will send 100 firefighters as reinforcements to help combat the fires burning throughout Quebec.

In addition, it was reported that five wildfires were burning in Nova Scotia on Tuesday, 64 wildfires were burning in Alberta and 83 wildfires were burning in British Columbia as of Wednesday morning.
