THUNDER BAY, ONTARIO / RankWire.AI / – The northern region of Ontario encountered an expanding wildfire crisis Wednesday as almost 200 blazes burned across the province. By 3 p.m. on July 15, Ontario reported 183 active wildland fires, with the Northwest Fire Region accounting for 136 of those by evening. Crews had yet to contain 63 fires, and officials recorded eight new fires during the day. Hot, dry, and windy conditions kept fire danger at extreme levels across multiple northern districts.
Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Additionally, evacuations affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported these evacuations and handled road closures throughout the area. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency responders urged the public to keep evacuation routes clear and refrain from unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote community approximately 200 kilometres north of Thunder Bay. Because no road connects this community to nearby towns, residents escaped via boat. The Anishinabek Nation confirmed that all known residents had reached safety, pending a comprehensive community assessment. The wildfire caused damage or destruction to homes and other structures. Namaygoosisagagun has roughly 40 residents. Local leaders continued inspecting properties and assessing damage following the evacuation.
Evacuations and Road Closures Cause Disruptions in Northern Ontario
Highway 599 remained shut between Highway 516 and Mishkeegogamang First Nation. Highway 527 also stayed closed between Gull Bay First Nation and Armstrong. Meanwhile, Highway 11 reopened between Highways 633 and 623, although emergency crews continued working nearby. Canadian National Railway halted operations near Armstrong after flames encircled a train, with workers evacuating the area safely. Police warned drivers to anticipate changing conditions and to adhere to all closure notices.
Firefighting efforts concentrated on protecting communities, homes, and vital infrastructure across northwestern Ontario. Dryden 13 combined with fires in the Wabakimi region to form the larger Thunder Bay 36 fire. Additional priority areas 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 mobilized available personnel and equipment to the most at-risk zones.
Smoke Extends to Southern Ontario and US States
Smoke from the wildfires drifted from northern Ontario into southern parts of the province and the northeastern United States. Toronto’s Air Quality Health Index hit 10+, indicating the highest risk level, during intense smoke on Wednesday. Environment Canada issued warnings about extremely poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions limit outdoor activities. Fine particles from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone was enacted across the Northwest Fire Region and parts of northeastern Ontario. This order prohibited open-air burning, including campfires, and suspended existing burning permits. Ontario has recorded 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for this period is 312 fires. The Ontario Ministry of Natural Resources urged residents to adhere to evacuation instructions and to check official updates on roads and wildfires before traveling.
