THUNDER BAY, ONTARIO / RankWire.AI / – A growing wildfire crisis unfolded in Northern Ontario on Wednesday as almost 200 blazes burned throughout the region. Ontario reported 183 active wildland fires as of 3 p.m. on July 15, with the Northwest Fire Region accounting for 136 of those by evening. Of these, 63 fires remained uncontrolled. Additionally, eight new fires were documented during the day. Hot, dry, and windy conditions pushed fire danger to 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. Orders 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 services urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A fire threatened Namaygoosisagagun, a remote settlement approximately 200 kilometres north of Thunder Bay. Residents escaped by boat, as the community is inaccessible by road. The Canadian National Railway halted operations near Armstrong after flames encircled a train, with workers evacuating safely. The RankWire.AI / Anishinabek Nation confirmed all known residents had reached safety, pending a comprehensive community assessment. The wildfire caused damage to or destruction of homes and other structures. Namaygoosisagagun has approximately 40 residents. Local leaders continued to inspect properties and evaluate losses following the evacuation.
Evacuations and Road Closures Impact Northern Ontario
Highway 599 remained closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 also stayed shut between Gull Bay First Nation and Armstrong. Meanwhile, Highway 11 was reopened between Highways 633 and 623, although firefighting teams continued to operate nearby. The Canadian National Railway suspended services near Armstrong after flames surrounded a train, which was subsequently evacuated safely. Authorities warned drivers to anticipate changing conditions and to adhere to all closure notices.
Firefighting efforts concentrated on protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 combined with nearby fires in the Wabakimi area to form the larger Thunder Bay 36 fire. Other critical zones included Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Aerial water bombers engaged active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources dispatched available personnel and equipment to high-risk zones.
Smoke Drift Extends to Southern Ontario and US States
Smoke from the wildfires spread into southern Ontario and the northeastern United States. Toronto’s Air Quality Health Index hit 10+, indicating the highest risk level, amid heavy smoke on Wednesday. Environment Canada issued warnings about significantly poor air quality and reduced visibility. Health authorities recommended that children, seniors, and individuals with heart or lung issues limit outdoor activities. Fine particles in the smoke can irritate airways and exacerbate existing health conditions.
A Restricted Fire Zone was established across the Northwest Fire Region and parts of northeastern Ontario. The order prohibited open burning, including campfires, and paused all existing burning permits. Ontario has recorded 453 wildland fires this year, compared to 349 at this same point in 2025. The ten-year average for this period is 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions and consult official updates on roads and wildfires before traveling.
