THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario encountered an expanding wildfire crisis Wednesday as close to 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. Crews had yet to bring 63 fires under control. Additionally, officials identified eight new fires during the day. Hot, dry, and windy conditions kept the fire threat at extreme levels across multiple northern districts.
Authorities issued evacuation orders in 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 supported the evacuations and managed road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for possible departure. Emergency teams urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote community approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat since no road connects the community to nearby towns. The Anishinabek Nation stated all known residents had reached safety, 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 damages 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 personnel continued operations nearby. Canadian National Railway halted activities near Armstrong after flames encircled a train. Workers evacuated safely. Police cautioned drivers to expect changing conditions and to adhere to all closure notices.
Firefighting efforts concentrated on protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 merged with nearby fires in the Wabakimi region to form the larger Thunder Bay 36 fire. Other key areas included Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Water bombers attacked active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources mobilized available personnel and equipment to address the highest-risk zones.
Smoke Drift Reaches Southern Ontario and US States
Wildfire smoke extended from northern Ontario into southern parts of the province and into 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 very poor air quality and limited visibility. Health officials urged children, seniors, and individuals with heart or lung conditions to minimize outdoor activities. Fine particles from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone was established in the Northwest Fire Region and parts of northeastern Ontario, banning open-air fires, including campfires, and suspending existing burning permits. Ontario reported 453 wildland fires this year, compared to 349 at the same point in 2025. The 10-year average for that period was 312 fires. The Ontario Ministry of Natural Resources advised residents to adhere to evacuation instructions and to consult official road and wildfire updates before traveling.
