THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario encountered an escalating wildfire crisis Wednesday as nearly 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 by sunset. Crews had yet to contain 63 of these fires. Additionally, officials recorded eight new fires during the day. Intense hot, dry, and windy conditions kept the fire danger at extreme levels across several northern districts.
Authorities mandated evacuations in Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Orders also extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported evacuation efforts and managed road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency responders urged the public to keep evacuation routes unobstructed and avoid non-essential travel.
A wildfire swept through Namaygoosisagagun, a remote settlement approximately 200 kilometres north of Thunder Bay. With no road access to nearby towns, residents evacuated by 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 around 40 inhabitants. Local leaders continued inspecting properties and assessing damages post-evacuation.
Evacuations and Road Closures Impact Northern Ontario
Highway 599 remained shut between Highway 516 and Mishkeegogamang First Nation, while Highway 527 was closed between Gull Bay First Nation and Armstrong. Highway 11 reopened between Highways 633 and 623, although nearby emergency operations persisted. Canadian National Railway halted services near Armstrong after flames encircled a train. Workers evacuated safely. Police cautioned drivers to anticipate changing conditions and adhere to all closure notices.
Firefighting teams prioritized communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 joined nearby fires in the Wabakimi region, forming the larger Thunder Bay 36 fire. Other critical zones included Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Aerial water bombers targeted active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources deployed available personnel and equipment to the highest-risk areas.
Wildfire Smoke Affects 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+, the highest risk level, amid heavy smoke on Wednesday. Environment Canada issued warnings about severely degraded air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions reduce outdoor activities. Fine particulate matter from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone was established across the Northwest Fire Region and parts of northeastern Ontario. The order prohibited open-air burning, including campfires, and suspended current burning permits. Ontario has recorded 453 wildland fires so far this year, compared to 349 by the same date 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.
