THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario faced an expanding wildfire crisis Wednesday as close to 200 blazes burned throughout the province. Ontario reported 183 active wildland fires at 3 p.m. on July 15, with the Northwest Fire Region accounting for 136 by the evening. Of these, 63 fires remained uncontrolled. Authorities also recorded eight new fires during the day. Hot, dry, and windy conditions kept fire danger at extreme levels across several northern districts.
Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Evacuations also affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted with evacuations and managed road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency crews urged the public to keep evacuation routes clear and avoid unnecessary travel.
A wildfire swept through Namaygoosisagagun, a remote settlement approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat, as no roads connect the community to neighboring towns. The Anishinabek Nation confirmed that all known residents had been safely evacuated, pending a comprehensive community assessment. The fire caused damage to or destruction of homes and other structures. Namaygoosisagagun has roughly 40 residents. Local leaders continued inspecting properties and assessing damage following the evacuation.
Evacuations and Road Closures Disrupt Life in Northern Ontario
Highway 599 remained shut between Highway 516 and Mishkeegogamang First Nation. Highway 527 also remained closed between Gull Bay First Nation and Armstrong. Highway 11 reopened between Highways 633 and 623, although emergency teams continued operations nearby. Canadian National Railway halted services near Armstrong after flames encircled a train. Workers evacuated safely. Police advised drivers to expect changing conditions and to adhere to all closure notices.
Firefighting efforts focused on protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 merged with nearby fires in the Wabakimi region, creating the larger Thunder Bay 36 fire. Other areas of concern included Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Water bombers targeted active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources dispatched available personnel and equipment to the most vulnerable zones.
Smoke Drift Extends into Southern Ontario and US States
Wildfire smoke spread from northern Ontario into southern regions of the province and across northeastern United States. Toronto’s Air Quality Health Index hit 10+, indicating very high risk, amid heavy smoke on Wednesday. Environment Canada issued warnings about poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions reduce outdoor activities. Fine particles from smoke can irritate airways and aggravate existing health issues.
A Restricted Fire Zone was enacted across the Northwest Fire Region and parts of northeastern Ontario. This order prohibited open fires, including campfires, and suspended existing burning permits. Ontario has reported 453 wildland fires so far this year, compared to 349 at the same point in 2025. The 10-year average for this period is 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions and check official road and wildfire updates before traveling.
