THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario encountered an expanding wildfire crisis Wednesday as almost 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 of them by evening. Crews had yet to bring 63 fires under control. During the day, officials also documented eight new fires. Hot, dry, and windy conditions contributed to extreme fire danger levels across several 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 included Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police coordinated evacuations and managed road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency responders urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote community roughly 200 kilometres north of Thunder Bay. Residents escaped by boat, as no road connects the community to nearby towns. The Anishinabek Nation confirmed all known residents had safely evacuated, pending a comprehensive community assessment. The fire caused damage or destruction to homes and other structures. Namaygoosisagagun has approximately 40 residents. Local leaders continued inspecting properties and assessing damages following the evacuation.
Evacuations and Road Closures Cause Disruption 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 crews continued operations nearby. Canadian National Railway halted services near Armstrong after flames encircled a train, from which workers evacuated safely. Police cautioned drivers to anticipate changing conditions and to adhere to all closure notices.
Firefighters concentrated their efforts on protecting communities, homes, and vital infrastructure across northwestern Ontario. Dryden 13 combined with 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 mobilized available personnel and equipment to high-risk zones.
Smoke Drift Extends into Southern Ontario and US States
Wildfire smoke from northern Ontario drifted into southern parts of the province and northeastern regions of the United States. Toronto’s Air Quality Health Index reached 10+, indicating the highest risk level, amid heavy smoke on Wednesday. Environment Canada issued warnings of poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions reduce outdoor activities. Fine particulate matter from smoke can irritate airways and aggravate existing health issues.
A Restricted Fire Zone was enacted in the Northwest Fire Region and parts of northeastern Ontario. The order prohibited open-air burning, including campfires, and suspended current burning permits. Ontario has reported 453 wildland fires this year, compared to 349 at the same point in 2025. The 10-year average for that period is 312 fires. The Ontario Ministry of Natural Resources advised residents to follow evacuation instructions and consult official updates on roads and wildfires prior to traveling.
