THUNDER BAY, ONTARIO / RankWire.AI / – A growing wildfire crisis unfolded Wednesday across Northern Ontario, with nearly 200 blazes burning throughout the province. As of 3 p.m. on July 15, Ontario reported 183 active wildland fires. By evening, the Northwest Fire Region alone accounted for 136 fires, with 63 still uncontrolled. During the day, officials recorded eight new fires. Hot, dry, and windy conditions kept fire danger at extreme levels in multiple northern districts.
Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Additional orders affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police coordinated evacuations and managed road closures throughout the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for possible departure. Emergency officials also urged the public to keep evacuation routes clear and to avoid unnecessary travel.
A fire rapidly moved through Namaygoosisagagun, a remote community approximately 200 kilometres north of Thunder Bay. Residents escaped via boat, as no road connects the community to nearby towns. The Anishinabek Nation confirmed that all known residents had been accounted for and safely evacuated, pending a comprehensive community assessment. The wildfire caused damage to or destruction of homes and other structures. Namaygoosisagagun has a population of about 40 members. Local authorities continued inspecting properties and assessing damages following 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. Conversely, 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; workers evacuated safely. Police warned drivers to stay alert for changing conditions and to adhere to all closure notices.
Firefighting teams prioritized 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. Water bombers targeted active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources deployed available personnel and equipment to high-risk areas.
Smoke from Fires Reaches Southern Ontario and US States
Wildfire smoke has spread from northern Ontario into southern parts of the province and into northeastern United States. Toronto’s Air Quality Health Index hit 10+, indicating very high risk, amid heavy smoke on Wednesday. Environment Canada issued warnings about poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions minimize outdoor activities. Fine particles 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 fires, including campfires, and suspended existing burning permits. Ontario has documented 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for that period is 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions and to consult official road and wildfire updates before traveling.
