THUNDER BAY, ONTARIO / RankWire.AI / – Nearly 200 wildfires burned across Ontario on July 15, with the majority concentrated in the northern regions. Provincial records indicated 183 active fires at 3 p.m. By evening, the Northwest Fire Region reported 136 fires, including 63 that remained uncontrolled. During the day, crews identified eight new fires. Several northern districts faced extreme fire danger as hot, dry, and windy conditions fueled rapid fire expansion.
Authorities issued evacuation orders for residents of Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. Evacuations also affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted with relocating residents and managing traffic on closed routes. Communities near Ignace, Crystal Lake, and Highway 633 were placed on evacuation alert. Emergency officials urged residents to prepare essential supplies and adhere to local guidance.
The fire caused significant damage at Namaygoosisagagun, a remote First Nation approximately 200 kilometres north of Thunder Bay. Since no road connects the community to nearby towns, residents evacuated by boat. The Anishinabek Nation confirmed that all known residents had reached safety, pending a full community assessment. The fire damaged or destroyed homes and public structures. With a population of around 40, Namaygoosisagagun community representatives began evaluating the damage after the evacuation.
Road Closures Hamper Evacuations and Emergency Response
Major routes across northwestern Ontario were shut down due to wildfire activity, disrupting travel between several remote communities. Highway 599 remained closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 also stayed closed between Gull Bay First Nation and Armstrong. Conversely, 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 encircled a train. The crew evacuated safely before conditions worsened.
Firefighters focused their efforts on communities, transportation routes, and critical infrastructure. The fire known as Dryden 13 merged with nearby blazes in the Wabakimi area, 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 established containment lines. The Ontario Ministry of Natural Resources deployed personnel and equipment to areas facing immediate risk.
Wildfire Smoke Diminishes Air Quality Over a Broader Area
Thick smoke drifted southward 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 cautioned that smoke had significantly degraded air quality and visibility. Health officials recommended 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 zone were suspended. This year, Ontario had documented 453 wildland fires, up from 349 by the same date in 2025. The 10-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.”}
