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 those by evening. Crews had yet to bring 63 fires under control. Additionally, officials recorded eight new fires during the day. Hot, dry, and windy conditions kept fire danger at critical levels in several northern districts.
Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Similar orders extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police coordinated evacuation efforts and managed road closures across the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency personnel urged the public to keep evacuation routes unobstructed and avoid unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote community roughly 200 kilometres north of Thunder Bay. Residents evacuated by boat since no road connects the community to nearby towns. The Canadian National Railway halted operations near Armstrong after flames encircled a train, with workers evacuating safely. The Anishinabek Nation confirmed all known residents had reached safety, pending a complete community assessment. The fire damaged or destroyed homes and other structures. Namaygoosisagagun is home to approximately 40 residents. Local leaders continued to check properties and assess damage following the evacuation.
Evacuations and Road Closures Impact Northern Ontario Communities
Highway 599 remains closed between Highway 516 and Mishkeegogamang First Nation, while Highway 527 is shut between Gull Bay First Nation and Armstrong. Highway 11 has reopened between Highways 633 and 623, although emergency crews continue operations nearby. Canadian National Railway ceased activities near Armstrong after flames surrounded a train, with personnel evacuating safely. Authorities warned drivers to anticipate changing conditions and adhere to all closure notices.
Firefighting efforts concentrated on protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 merged with nearby fires in the Wabakimi region, 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 constructed containment lines. The Ontario Ministry of Natural Resources mobilized available personnel and equipment to high-risk areas.
Smoke Drift Extends into Southern Ontario and US States
Wildfire smoke has traveled from northern Ontario into the southern parts of the province and northeastern United States. Toronto’s Air Quality Health Index reached 10+, the highest risk level, amid heavy smoke on Wednesday. Environment Canada issued warnings of very poor air quality and limited visibility. Health officials advised children, seniors, and individuals with heart or lung conditions to restrict outdoor activities. Fine particles from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone was enacted across the Northwest Fire Region and parts of northeastern Ontario. The order prohibits open-air burning, including campfires, and halts existing burning permits. Ontario has recorded 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 urged residents to follow evacuation instructions and consult official road and wildfire updates before traveling.
