THUNDER BAY, ONTARIO / RankWire.AI / – Nearly 200 wildfires burned across Ontario on July 15, with the majority of blazes concentrated in the northern region. Provincial authorities reported 183 active fires at 3 p.m. The Northwest Fire Region recorded 136 fires by evening, including 63 that remained uncontrolled. During the day, crews identified eight new fires. Several northern districts faced extreme fire danger due to hot, dry, and windy conditions that fueled rapid fire expansion.
Officials ordered residents to evacuate Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Evacuation directives also extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted in relocating residents and managing traffic near closed roads. Authorities placed communities near Ignace, Crystal Lake, and Highway 633 on evacuation alert. Emergency personnel advised residents to prepare essential supplies and follow local guidance.
The fire caused significant destruction at Namaygoosisagagun, a remote First Nation approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat since no road connects the community to neighboring towns. The Anishinabek Nation confirmed that all known residents had reached safety, pending a comprehensive community assessment. The flames damaged or destroyed homes and public buildings. Namaygoosisagagun has roughly 40 residents. Community representatives have begun evaluating the damage after the evacuation.
Road closures hinder evacuation efforts and emergency response
Major routes across northwestern Ontario faced closures due to wildfire activity, complicating travel between remote communities. Highway 599 remained closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 was shut between Gull Bay First Nation and Armstrong. Highway 11 reopened between Highways 633 and 623, although emergency crews continued operations in the area. Canadian National Railway halted service near Armstrong after a fire surrounded a train. The crew evacuated safely before the situation worsened.
Firefighting efforts focused on communities, transportation corridors, and vital infrastructure. The Dryden 13 fire merged with nearby blazes in the Wabakimi region, creating the larger Thunder Bay 36 fire. Crews also operated near Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Water bombers targeted active fire zones while ground teams constructed containment lines. The Ontario Ministry of Natural Resources deployed personnel and equipment to areas at the highest immediate risk.
Wildfire smoke impacts air quality across a broader area
Thick smoke drifted south from northern Ontario, reaching parts of the northeastern United States. Toronto recorded an Air Quality Health Index of 10+, indicating the highest risk level. Environment Canada warned that smoke had significantly degraded air quality and visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions limit outdoor activities. Fine particles in wildfire smoke can irritate lungs and exacerbate existing health issues.
Ontario declared a Restricted Fire Zone across the Northwest Fire Region and sections of northeastern Ontario. The order banned campfires and other open-air fires. All active burning permits within the restricted area were suspended. To date, Ontario has recorded 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for this period is 312. The Ontario Ministry of Natural Resources urged residents to stay informed through official evacuation, highway, and wildfire notices.
