THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario encountered an escalating wildfire crisis Wednesday as close to 200 fires burned throughout the region. Ontario reported 183 active wildland fires as of 3 p.m. on July 15, with the Northwest Fire Region alone accounting for 136 fires by evening. Of these, 63 remained uncontrolled. Additionally, officials identified eight new fires during the day. Hot, dry, and windy conditions kept fire risk at extreme levels across multiple northern districts.
Authorities issued evacuation orders in Armstrong, Whitesand First Nation, Gull Bay First Nation, and Lac des Mille Lacs First Nation. The directives also affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police coordinated evacuations and managed road closures throughout the affected areas. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency responders urged the public to keep evacuation routes unobstructed and to avoid unnecessary travel.
A wildfire impacted Namaygoosisagagun, a remote community approximately 200 kilometres north of Thunder Bay. Residents evacuated by boat due to the absence of road access to nearby towns. The Canadian National Railway halted operations near Armstrong after flames encircled a train, but workers evacuated safely. The Anishinabek Nation confirmed that all known residents had reached safety, with ongoing community assessments underway. The fire damaged or destroyed homes and other structures. Namaygoosisagagun has an estimated population of around 40 members. Local leaders continued inspecting properties and assessing damages post-evacuation.
Evacuations and Road Closures Impact Northern Ontario
Highway 599 remains shut between Highway 516 and Mishkeegogamang First Nation. Highway 527 also remains closed between Gull Bay First Nation and Armstrong. Meanwhile, Highway 11 has reopened between Highways 633 and 623, although emergency crews continue operations nearby. Authorities warned drivers to anticipate changing conditions and adhere to all closure notices.
Firefighting teams prioritized protecting communities, residences, and vital infrastructure across northwestern Ontario. The Dryden 13 fire combined with nearby fires in the Wabakimi area to form the larger Thunder Bay 36 blaze. Other key locations included Quetico Provincial Park, Atikokan, Upsala, Cat Lake, and Fort Hope. Aerial water bombers targeted active fire fronts while ground crews established containment lines. The Ontario Ministry of Natural Resources dispatched available personnel and equipment to areas at highest risk.
Smoke Extends to Southern Ontario and US States
Wildfire smoke drifted from northern Ontario into southern parts of the province and the northeastern United States. Toronto’s Air Quality Health Index soared to 10+, the highest warning level, during heavy smoke on Wednesday. Environment Canada cautioned about very poor air quality and limited visibility. Health officials recommended that children, seniors, and individuals with heart or lung conditions reduce outdoor activities. Fine particulate matter from the smoke can irritate airways and exacerbate existing health issues.
A Restricted Fire Zone was established across the Northwest Fire Region and parts of northeastern Ontario. The order prohibited open fires, including campfires, and suspended current burning permits. Ontario reported 453 wildland fires this year, compared to 349 at the same point in 2025. The ten-year average for that period is 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions and to consult official road and wildfire updates before traveling.
