Evacuation, implementation orders
Evacuation orders or alerts remain in effect for areas near the following fires:
Those under evacuation orders are required to leave the area, while those under evacuation alerts are urged to prepare to evacuate.
The Ministry of Natural Resources’ Thunder Bay–Ignace District has invoked implementation orders near the following fires:
- Dryden 34 and 35.
- Fort Frances 14.
- Thunder Bay 36, 54 and 56.
Implementation orders limit people’s ability to travel in and around these fires.
Northwestern Ontario and a small portion of northeastern Ontario remain under a restricted fire zone, which means no open-air burning, including campfires, is allowed.
The forest fire hazard is mostly moderate across the northwest, with pockets of high hazard toward Kenora and Dryden.
Highway closures in effect
According to the province’s interactive highway map, the following roads are closed due to wildfire activity:
- All lanes are closed in both directions on Lac des Mille Lacs Road from Inwood Road to Highway 17.
- Highway 811 is closed, with the exception of local traffic evacuating the area.
- Highway 527 is closed in both directions between Tertiary Highway 811 and Armstrong.
The Ontario Provincial Police (OPP) urge people for their safety and the safety of emergency responders to:
- Stay away from affected areas and refrain from attending wildfire scenes to take photos or videos.
- Remain calm and follow all evacuation orders and emergency instructions issued by local authorities.
- Avoid non-essential travel in affected areas.
- Monitor official sources for the latest information and evacuation updates.
- Remain away from evacuated areas until authorities have advised it is safe to return.
- Help keep roadways clear so emergency personnel can carry out their work safely and effectively.
- If evacuating, bring essential medications, identification, important documents, mobile devices and chargers and any items required to support family members and pets.

Evacuee total now 2,835
There are now more than 2,835 wildfire evacuees from more than a dozen communities across the province, according to an update issued by Ontario’s Minister of Emergency Preparedness and Response, Jill Dunlop, on Friday evening.
They are staying in eight official host communities.
There have been four Ontario Corps partners and 17 Ontario Corps volunteers sent to help. As well, the province said the following equipment/supplies have been provided:
- 312 air purifiers.
- 84 air filters.
- Five air scrubbers.
- 2,640 N-95 masks.
- 4,340 hygiene kits.
- 80 food hampers.
As part of these efforts, Feed Ontario and the Ontario Federation of Indigenous Friendship Centres are shipping and distributing food to evacuees.
In addition, the Kaministiquia and Upsala fire departments were among some regional fire services to receive wildland fire skids from GlobalMedic.
This year’s wildfire season in northwestern Ontario has shone a light on the challenges facing smaller fire departments, as volunteers do what they can with the limited resources at their disposal. Here’s how GlobalMedic is supporting those on the front lines to help them better protect their communities.
Mexico, Alberta, New Brunswick, Newfoundland, the Yukon, PEI, the Canadian Forest Service and the Canadian Interagency Forest Fire Centre have also offered province-wide assistance.
