Ontario’s Ministry of Natural Resources (MNR) continues to monitor wildfires across the province, with varying conditions in the northeast and northwest regions. While some fires have been brought under control, others remain active, prompting ongoing suppression efforts and precautionary measures.
Northeast region
The northeast region reports two active wildfires, with one recently contained.
Sudbury 13, a 0.5-hectare fire near Wikwemikong that was identified on Saturday, was declared out Sunday morning.
Cochrane 2, an 8-hectare fire northwest of Attawapiskat, is now under control.
Cochrane 3, burning 48 kilometres west of Attawapiskat, remains not under control at 150 hectares. Though the MNR confirms no immediate threats to communities or infrastructure at this time.
The fire hazard ranges from low to moderate across most of the region, though Onaping Falls and Elliot Lake face a high hazard rating.
Northwest region
The northwest region remains a focal point, with 15 active fires and persistent high-risk conditions.
New fires
Thunder Bay 15, a 0.1-hectare fire on Thompson Island, is not yet under control.
Nipigon 8, near Fort Hope First Nation, was contained Sunday morning at 0.2 hectares.
Major Fires
- Red Lake 12 has been remapped to 12,559 hectares. An Ontario Incident Management Team is leading suppression, with crews prioritizing Deer Lake First Nation’s protection.
“Winds were favourable today, helping fire crews make good progress,” the Aviation, Forest Fire and Emergency Services said in its update on Saturday evening.
“Fire ranger crews continue to make good progress on values protection. Fire crews have established hose lines on the east side of the community.”
- Nipigon 5 remains out of control and now measures more than 7,506 hectares, with firefighters establishing hose lines near Webequie First Nation.
- Kenora 20, now measuring 34,008 hectares, had additional support crews on Saturday to assist with suppression efforts. Cooler temperatures aided efforts, but the Manitoba border flank remains active.
- Kenora 14 (1,607 ha), Fort Frances 4 (3,593 ha), and Sioux Lookout 3 (1,849 ha) are all being held.
The MNR acknowledged British Columbia wildfire crews for their support with Kenora 14 and 20 as they headed home Saturday.

Restrictions and evacuations
A Restricted Fire Zone is in effect, with travel bans and evacuation orders near Kenora 32, 20, and 14 along with Red Lake 12 and Nipigon 5. Crown land use and lake access are prohibited in designated areas.
The fire hazard is high to extreme across the northwest region.
Wildfire smoke
Most of northwestern Ontario continues to be impacted by smoke drift from Kenora 20 and active wildfires in Manitoba.
“Smoke is likely to continue impacting the local (Deer Lake First Nation) area throughout the weekend,” said the ministry.
