The 2026 Ontario wildfire season became the worst on record, with over 7,250 sq km burned, surpassing the 2021 high. In July, the Northwest Region faced intense activity, including the Fort Frances 14 and 15 fires within the Atikokan Cluster. The expansion of these fires triggered evacuation alerts for several townships in the Thunder Bay-Ignace District. Extreme heat, reaching 40 °C, and dry thunderstorms contributed to the crisis, displacing approximately 2,000 residents from over a dozen communities. The Namaygoosisagagun (Collins) First Nation was consumed by flames, forcing residents to flee by boat. Local leaders, including Chief Helen Paavola, criticized the provincial and federal response as inadequate, noting delays in support. Heavy smoke from the blazes drifted south, impacting air quality across several U.S. states, including Michigan, Wisconsin, and Illinois. By late July, the situation began to ease. Natural Resources Minister Mike Harris Jr. stated the season was “getting back to normal” after crews extinguished 80 fires over a fortnight. As of July 30, 159 fires remained active, though many were being observed without active suppression. The massive Thunder Bay 36 complex continued to burn but showed minimal growth. Despite the easing conditions, First Nations and U.S. officials continue to call for a public inquiry into evacuation support and fire-management strategies. Nationally, the wildfire season has been severe, with approximately 4 million hectares burned across Canada. By mid-August, Canada was on track for its fourth worst wildfire season on record, with more than 40,000 square kilometres of forest burned. While 580 wildfires remained active across the country, 30 were classified as out of control. Federal forecasters warned that September fire risks would remain well above seasonal averages in northern British Columbia, northern Quebec, and most of Labrador.
