THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario experienced an escalating 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. By evening, the Northwest Fire Region contributed 136 fires, with 63 still uncontrolled. Additionally, officials recorded eight new fires 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. Orders also extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported the evacuations and managed road closures throughout the area. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency personnel urged the public to keep evacuation routes clear and avoid non-essential travel.
A fire ravaged Namaygoosisagagun, a remote community approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat, as no road connects the community to nearby towns. The Anishinabek Nation confirmed that all known residents had been evacuated safely, pending a comprehensive community assessment. The wildfire caused damage to or destruction of homes and other structures. With a population of about 40, Namaygoosisagagun’s leaders continued inspecting properties and assessing damage after the evacuation.

Meanwhile, Highway 11 has reopened between Highways 633 and 623, though emergency crews continue working nearby. Canadian National Railway halted operations 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 teams concentrated on safeguarding communities, residences, and essential infrastructure across northwestern Ontario. Dryden 13 merged with fires in the Wabakimi region, forming the larger Thunder Bay 36 blaze. 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 the highest-risk areas.
Smoke Drifts into Southern Ontario and US Northeastern States
Wildfire smoke has drifted from northern Ontario into southern parts of the province and northeastern United States. Toronto’s Air Quality Health Index hit 10+, the highest risk level, amid heavy smoke on Wednesday. Environment Canada warned of very poor air quality and limited visibility. Health officials advised children, seniors, and individuals with heart or lung conditions to reduce outdoor activity. Fine particulate matter from smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone has been established in the Northwest Fire Region and parts of northeastern Ontario. The order prohibits open fires, including campfires, and suspends all existing burning permits. Ontario reported 453 wildland fires so far this year, compared to 349 at this point 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 check official updates on roads and wildfires before traveling.
