THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario is currently experiencing an expanding wildfire crisis as almost 200 blazes are active across the region. Ontario reported 183 ongoing wildland fires at 3 p.m. on July 15, with the Northwest Fire Region containing 136 of those by nightfall. Of these, 63 fires remained uncontrolled. Additionally, officials identified eight new fires during the day. Hot, dry, and windy weather conditions have pushed fire danger to extreme levels across multiple northern districts.

Authorities issued evacuation orders for Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. These directives also affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported the evacuations and managed road closures within the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency personnel urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A wildfire advanced through Namaygoosisagagun, a remote settlement located approximately 200 kilometres north of Thunder Bay. Residents escaped using boats, as no road links 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. With a population of around 40, local leaders continued inspecting properties and assessing damages following evacuation.
Evacuations and Road Closures Impact 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. Meanwhile, Highway 11 has reopened between Highways 633 and 623, although emergency crews are still operating nearby. Canadian National Railway halted operations near Armstrong after flames encircled a train. The workers evacuated safely. Law enforcement warned drivers to anticipate changing conditions and to adhere to all closure notices.
Firefighting teams concentrated on protecting communities, residences, and vital infrastructure throughout northwestern Ontario. Dryden 13 combined with nearby fires in the Wabakimi area to form the larger Thunder Bay 36 blaze. Other priority regions 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 dispatched available personnel and equipment to the highest-risk zones.
Smoke Extends into Southern Ontario and Northeastern US
Smoke from the wildfires has drifted into southern Ontario and parts of the northeastern United States. Toronto’s Air Quality Health Index hit 10+, the highest level of risk, amid heavy smoke on Wednesday. Environment Canada issued warnings of very poor air quality and limited visibility. Health authorities advised children, seniors, and individuals with heart or lung conditions to reduce outdoor activity. Fine particulate matter from smoke can cause airway irritation and aggravate existing health issues.
A Restricted Fire Zone has been implemented across the Northwest Fire Region and parts of northeastern Ontario. The order prohibits open fires, including campfires, and halts existing burning permits. Ontario has reported 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for this period is 312 fires. The Ontario Ministry of Natural Resources urged residents to comply with evacuation orders and to consult official updates on roads and wildfires before traveling.
