THUNDER BAY, ONTARIO / RankWire.AI / – Nearly 200 wildfires spread across Ontario on July 15, predominantly in the northern regions. Provincial authorities reported 183 active fires at 3 p.m., with the Northwest Fire Region accounting for 136 fires by evening, including 63 that remained uncontrolled. During the day, firefighting teams identified eight new blazes. Several northern districts faced extreme fire danger due to hot, dry, and windy conditions that accelerated fire growth.
Residents of Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation were ordered to evacuate. Evacuation notices also extended to Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police assisted with relocating residents and managing traffic on roads that were closed. Communities near Ignace, Crystal Lake, and Highway 633 were placed on evacuation alert. Emergency officials advised residents to prepare essential supplies and adhere to local guidance.
Namaygoosisagagun, a remote First Nation situated approximately 200 kilometres north of Thunder Bay, suffered significant damage from the flames. With no road access, residents evacuated by boat. The Anishinabek Nation confirmed that all known residents had reached safety, pending a full community assessment. The fire destroyed or damaged homes and public buildings. The community, which has around 40 members, began evaluating the extent of the damage following the evacuation.
Road Closures Hamper Evacuations and Emergency Operations
Major routes across northwestern Ontario were shut down due to wildfire activity, complicating travel between remote communities. Highway 599 remained closed between Highway 516 and Mishkeegogamang First Nation. Highway 527 was also closed between Gull Bay First Nation and Armstrong. Highway 11 reopened between Highways 633 and 623, but emergency crews continued operating in the area. Canadian National Railway halted services near Armstrong after a fire surrounded a train; the crew evacuated safely before conditions worsened.
Firefighters prioritized efforts around communities, transportation routes, and critical infrastructure. The fire known as Dryden 13 merged with nearby blazes in the Wabakimi region, creating the larger Thunder Bay 36 fire. Crews also responded near Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Water bombers targeted active fire zones, while ground crews constructed containment lines. The Ontario Ministry of Natural Resources deployed personnel and equipment to areas at immediate risk.
Wildfire Smoke Deteriorates Air Quality Over a Broader Area
Thick smoke drifted south from northern Ontario, reaching parts of the northeastern United States. Toronto’s Air Quality Health Index surged to 10+, indicating the highest health risk level. Environment Canada issued warnings that smoke had significantly reduced air quality and visibility. Health authorities recommended that children, seniors, and individuals with heart or lung conditions limit outdoor activities. The 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 sections of northeastern Ontario. This order banned campfires and other open-air burning activities. All active burning permits within the restricted zone were suspended. So far in 2025, Ontario has recorded 453 wildland fires, an increase from 349 at the same point in 2024. The ten-year average for this period stands at 312. The Ontario Ministry of Natural Resources urged residents to stay informed through official evacuation, highway, and wildfire alerts.”}
