Ontario's Ministry of Natural Resources says crews continue to make good progress battling the fire known as Parry Sound 33 in the northeast part of the province.
The ministry says the fire is being held to about 110 square kilometres.
It adds that residents affected by the fire were able to return home after an evacuation order was lifted on Friday.
As of Saturday morning, there were 44 active forest fires in Ontario, including six that remained out of control.
Meantime, in B.C., residents living on the west side of Quesnel are preparing for a possible city-wide evacuation as wildfires continue to rage near the city.
Almost 4,500 people in an area stretching roughly 70 kilometres west of Quesnel are under evacuation alert, while 90 people and more than 900 properties in area two hours northwest of the city were evacuated Saturday.
Quesnel Fire Chief Sylvain Gauthier says they're preparing for a full-scale evacuation in case the fires push eastwards, reserving busses in Prince George, an hour's drive north, for residents who don't have access to a vehicle.
Gauthier says Northern Health has been told to prepare to evacuate G.R. Baker Memorial Hospital as well.
Meanwhile, Sunday's forecast calls for more hot, dry weather along with gusting winds, which could fan the flames.
