Other wildfires have marred the northern areas, CTV said, but the Kisseynew Lake fire was by far the largest. The blaze has been burning for more than a week.
But officials said the fire situation has improved enough that campgrounds in Grass River Provincial Park were expected to reopen Thursday. Thunderstorms were in the forecast.
Officials said 440 firefighters were working on the Kisseynew Lake fire. Some had traveled from other Canadian provinces and the United States.
Equipment had also been sent to Manitoba, allowing 13 water bombers and 13 helicopters to be turned on the flames.
