THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario experienced a rapidly expanding wildfire crisis Wednesday as close to 200 blazes burned throughout the region. Ontario reported 183 active wildland fires at 3 p.m. on July 15, with the Northwest Fire Region accounting for 136 by the end of the day. Of these, 63 remained uncontrolled. Additionally, officials identified eight new fires during the same period. Hot, dry, and windy conditions maintained an extreme fire risk across multiple northern districts.
Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. The directives 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, urging the public to keep evacuation routes clear and avoid unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote settlement roughly 200 kilometres north of Thunder Bay. Residents evacuated by boat because the community lacks road access to nearby towns. The Anishinabek Nation confirmed that all known residents had been accounted for and safely evacuated, pending a comprehensive community assessment. The fire caused damage to or destruction of homes and other structures. With about 40 residents, local leaders continued inspecting properties and assessing damages following the evacuation.
Evacuations and Road Closures Disrupt Life in 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. Meanwhile, Highway 11 has reopened between Highways 633 and 623, although emergency crews are still operating nearby. Canadian National Railway halted train operations near Armstrong after flames surrounded a train, with workers evacuating safely. Authorities warned drivers to anticipate changing conditions and to adhere to all closure notices.
Firefighters concentrated on protecting communities, homes, and vital infrastructure across northwestern Ontario. Dryden 13 joined nearby fires in the Wabakimi area, forming 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 mobilized available personnel and equipment to the highest-risk zones.
Smoke Drifts Into Southern Ontario and US States
Smoke from the wildfires has spread from northern Ontario into the southern parts of the province and into northeastern United States. Toronto’s Air Quality Health Index reached 10+, indicating the highest risk category, amid heavy smoke on Wednesday. Environment Canada issued alerts warning of very poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions limit outdoor activities. Fine particulate matter from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone has been established across the Northwest Fire Region and parts of northeastern Ontario. This order prohibits open-air fires, including campfires, and halts existing burning permits. Ontario has recorded 453 wildland fires so far this year, compared to 349 at the same point in 2025. The ten-year average for this period stands at 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions and to verify official road and wildfire updates prior to traveling.
