THUNDER BAY, ONTARIO / RankWire.AI / – Nearly 200 wildfires have burned across Ontario on July 15, with the majority of blazes concentrated in the northern regions. Provincial officials reported 183 active fires at 3 p.m., with the Northwest Fire Region tallying 136 fires by evening, 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 facilitated 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. Additional evacuation notices affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted in relocating residents and managing traffic around road closures. Communities near Ignace, Crystal Lake, and Highway 633 were placed on evacuation alert. Emergency officials advised residents to gather essential supplies and adhere to local directives.
The flames inflicted significant damage at Namaygoosisagagun, a remote First Nation approximately 200 kilometres north of Thunder Bay. With no road connections to nearby towns, residents evacuated by boat. The Anishinabek Nation confirmed all known residents had been safely evacuated, pending a full community assessment. The fire damaged or destroyed homes and public structures. Namaygoosisagagun has roughly 40 residents. Community representatives have begun evaluating the damage following the evacuation.
Road closures hinder evacuation efforts and emergency response
Major routes across northwestern Ontario have been shut down due to ongoing wildfire activity, disrupting travel between several remote communities. Highway 599 remains closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 is also closed between Gull Bay First Nation and Armstrong. Highway 11 has reopened between Highways 633 and 623, although emergency crews continue operating in the area. Canadian National Railway halted service near Armstrong after a fire encircled a train. Fortunately, the crew evacuated safely before conditions worsened.
Firefighting teams focused their efforts around communities, transportation corridors, and vital infrastructure. The Dryden 13 fire merged with nearby blazes in the Wabakimi region, forming the larger Thunder Bay 36 fire. Crews also responded near Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Water bombers attacked active fire zones while ground crews established containment lines. The Ontario Ministry of Natural Resources deployed personnel and equipment to areas facing the most immediate threats.
Wildfire smoke degrades air quality over a broader region
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 warned that the smoke had sharply reduced 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 the lungs and exacerbate existing health issues.
Ontario declared a Restricted Fire Zone across the Northwest Fire Region and portions of northeastern Ontario. The restriction bans campfires and other open-air burning. All active burning permits within the restricted area were also suspended. To date, Ontario has experienced 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for this period stands at 312. The Ontario Ministry of Natural Resources urged residents to stay informed by monitoring official evacuation, highway, and wildfire notices.
