Members of the Canadian Armed Forces have been brought in to assist firefighters, and air tankers are also part of the fight.
Two more of these images show an area near Enterprise, a hamlet close to the Alberta border and among the first to be evacuated. The settlement was destroyed by fires.

Devastation from wildfires was visible from the Earth's orbit elsewhere in Canada as well.
Other images captured by Sentinel-2 show damage in the wake of a fire in the Okanagan area of British Columbia.
The satellite imagery shows the Eagle Bluff area, near Osoyoos, B.C., and Oroville, Wash., as they appeared on July 28, July 21, Aug. 2 and Aug. 12.
The first images show the area as it was, while the second and third show smoke during a wildfire that tore through 70 square kilometres of land on both sides of the border. The final images show the damage left behind.
The photos at the bottom show the natural colour, as seen from orbit, while the images at the top are shortwave-infrared, and show smoke, active fire locations and delineation of the area, officials told CTVNews.ca.
