THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario encountered an expanding wildfire crisis Wednesday as close to 200 blazes burned throughout the province. 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. Firefighters had yet to contain 63 of the fires. Additionally, officials recorded eight new fires during the day. Hot, dry, and windy conditions kept fire risk at extreme levels across multiple northern districts.
Authorities mandated evacuations in Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. The orders also extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported the 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 officials urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A wildfire affected Namaygoosisagagun, a remote settlement approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat since no road connects the community to nearby towns. The Anishinabek Nation confirmed that all known residents had reached safety, pending a comprehensive community assessment. The fire caused damage to or destruction of homes and other structures. Namaygoosisagagun has an estimated population of about 40 members. Local leaders continued to check properties and assess damages post-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. Highway 11 has reopened between Highways 633 and 623, although emergency crews continue operations nearby. Canadian National Railway halted activities near Armstrong after flames surrounded a train. The workers evacuated safely. Police advised drivers to expect changing conditions and to adhere to all closure notices.
Firefighting teams prioritized protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13 combined efforts with nearby fires in the Wabakimi area to form 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 deployed available personnel and equipment to the highest-risk zones.
Smoke Drift Reaches Southern Ontario and US States
Wildfire smoke has spread from northern Ontario into the southern parts of the province and into the northeastern United States. Toronto’s Air Quality Health Index hit 10+, the highest danger level, during heavy smoke on Wednesday. Environment Canada issued warnings about very poor air quality and reduced visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions limit outdoor activities. Fine particles from the smoke can irritate the respiratory system and exacerbate existing health issues.
A Restricted Fire Zone was established covering the Northwest Fire Region and parts of northeastern Ontario. The order prohibited open burning, including campfires, and suspended existing burning permits. Ontario has recorded 453 wildland fires so far this year, compared with 349 at the same 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 verify official road and wildfire updates before traveling.
