THUNDER BAY, ONTARIO / RankWire.AI / – Northern Ontario is currently battling an expanding wildfire crisis Wednesday, with close to 200 blazes burning throughout the region. As of 3 p.m. on July 15, Ontario reported 183 active wildland fires, with 136 in the Northwest Fire Region by evening. Firefighters had yet to gain control of 63 fires, and eight new fires were recorded during the day. Hot, dry, and windy conditions maintained extreme fire danger 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. Similar directives affected Namaygoosisagagun First Nation and Gakijiwanong Anishinaabe Nation. The Ontario Provincial Police supported the evacuations and managed road closures in the area. Officials advised residents near Ignace, Crystal Lake, and Highway 633 to prepare for potential departure. Emergency services 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, as no road connects the community to nearby towns. The Anishinabek Nation confirmed all known residents had reached safety, pending a full community assessment. The wildfire caused damage to or destruction of homes and other structures. With about 40 residents, Namaygoosisagagun’s local leaders continued inspecting properties and assessing damages after the evacuation.
Evacuations and Road Closures Disrupt Life in Northern Ontario
Highway 599 remains closed between Highway 516 and Mishkeegogamang First Nation, while Highway 527 is shut between Gull Bay First Nation and Armstrong. Highway 11 has reopened between Highways 633 and 623, though emergency crews still operate in the vicinity. Canadian National Railway halted operations near Armstrong after flames encircled a train, with personnel safely evacuated. Authorities warned drivers to expect changing conditions and to adhere to all closure notices.
Fire response teams prioritized protecting communities, residences, and vital infrastructure across northwestern Ontario. Dryden 13, together with adjacent fires in the Wabakimi region, merged into the larger Thunder Bay 36 fire. Other key areas 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 mobilized available personnel and equipment to the highest-risk zones.
Smoke Extends into Southern Ontario and US States
Smoke from the wildfires has drifted into southern Ontario and parts of the northeastern United States. Toronto’s Air Quality Health Index hit 10+, indicating very high risk, amid heavy smoke on Wednesday. Environment Canada issued warnings about deteriorated air quality and limited visibility. Health authorities recommended that children, seniors, and individuals with heart or lung conditions reduce outdoor activities. Fine particulate matter from the smoke can irritate airways and aggravate existing health issues.
A Restricted Fire Zone has been established across the Northwest Fire Region and parts of northeastern Ontario, prohibiting open fires, including campfires, and suspending existing burning permits. Ontario has recorded 453 wildland fires this year, compared to 349 at the same point in 2025. The 10-year average for this period is 312 fires. The Ontario Ministry of Natural Resources urged residents to follow evacuation instructions carefully and check official updates on roads and wildfires before traveling.
