THUNDER BAY, ONTARIO / RankWire.AI / – A growing wildfire crisis unfolded in Northern Ontario Wednesday as nearly 200 blazes burned throughout the region. At 3 p.m. on July 15, Ontario reported 183 active wildland fires, with the Northwest Fire Region accounting for 136 by evening. Of these, 63 remained uncontrolled. Additionally, eight new fires were reported 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. These orders also affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted with evacuations and coordinated road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for possible departure. Emergency officials urged the public to keep evacuation routes clear and avoid unnecessary travel.
A wildfire swept through 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 confirmed that 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 a population of about 40 members. Local leaders continued inspecting properties and assessing damage after the evacuation.
Evacuations and Road Closures Impact Northern Ontario
Highway 599 remains closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 also remains shut between Gull Bay First Nation and Armstrong. Highway 11 has reopened between Highways 633 and 623, although firefighting efforts are ongoing nearby. Canadian National Railway halted operations near Armstrong after flames encircled a train, with workers evacuating safely. Police warned drivers to anticipate changing conditions and adhere to all closure notices.
Firefighting teams prioritized protecting communities, residences, and critical infrastructure across northwestern Ontario. Dryden 13 joined nearby fires in the Wabakimi area, forming the larger Thunder Bay 36 fire. Other key 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 deployed available personnel and equipment to areas at highest risk.
Smoke Drift Reaches Southern Ontario and US States
The smoke from the wildfires spread from northern Ontario into southern parts of the province and the northeastern United States. On Wednesday, Toronto’s Air Quality Health Index reached 10+, indicating the highest risk level, due to heavy smoke. Environment Canada issued warnings about very poor air quality and reduced visibility. Health officials advised children, seniors, and individuals with heart or lung conditions to limit outdoor activities. Fine particulate matter from the smoke can irritate airways and worsen existing health issues.
A Restricted Fire Zone was established 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 by the same date 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 consult official road and wildfire updates before traveling.
