Thunder Bay, Ontario — analysis of the wildfires in Ontario and the Northwest Territories details how their intensity this season is placing more challenges on the ability to prevent their devastating impact, and warns about what might happen if things don't change.
“The wildfires we see now, they're not very rare, but they're incredibly hard to suppress with the available people power, with the available technology,” Friederike Otto, a professor of climate science at Imperial College London, told a virtual news conference Wednesday. “If you now imagine that even if it's just a little bit worse, it would mean that everything is even stretched further.” According to the analysis, released Thursdayby Imperial College London’s World Weather Attribution(WWA), human-induced climate change has made the extreme weather conditions behind the Ontario and N.W.T. wildifres about twice as likely to occur in future.
More than 3.8 million hectares of land — including over 730,000 hectares in Ontario alone — have burned across Canada this year, it notes. Founded in 2014, U.K.-based WWA says it works with scientists around the world to measure how climate change influences the intensity and likelihood of extreme weather. For the newly released research, researchers used observations and climate models focusing on seven-day and 30-day periods of the most extreme fire weather in Ontario and the Northwest Territories. They compared these conditions against what would have been expected in a world without fossil fuel emissions.
As well, communities are finding themselves displaced year after year, with First Nations disproportionately affected.
This aligns with the large-scale evacuation of several communities in northwestern Ontario. At its peak, more than 2,800 people from the region were displaced; that’s been reduced to just over 1,600 according to the newest Ontario government count. July also saw the total destruction of two communities in the region:Namaygoosisagagun First Nation(also known as Collins First Nation) andWhitewater Lake First Nation. At that time, “the wildfires were driven by the rapid advancement of a week of serious fire weather following widespread lightning activity in the region,” indicated Theodore Keeping, a climate scientist at Imperial College London. Jonathan Boucher, a wildland fire research scientist for the Canadian Forest Service of Natural Resources Canada, was also involved in the WWA research. Keeping advised that what also stands out is not only how much land has burned this summer, but how quickly it was destroyed. “Only within a few days and weeks, large areas have been burned,” Boucher shared. “Also, what's making 2026 special is that Ontario reached its highest-ever recorded area burned in recent history.” This First Nation in Ontario cautions against premature optimism over forest fire threats First Nations chiefs call for public inquiry as Ontario defends forest fire response Recent summers in Canada have become characterized by large plumes of smoke crossing international borders, putting millions of people’s health at risk, he advised. As well, communities are finding themselves displaced year after year, with First Nations disproportionately affected. “I think that the message that I would want to send to Mark Carney, very simply, is that if you export fossil fuels, the impacts of the burning of those fossil fuels come home,” Keeping noted about Canada’s prime minister. Chris Boyer is atechnical adviser of climate and health at Red Cross Red Crescent Climate Centre, which has its head office in the Netherlands, also spoke at Wednesday’s news conference. When asked what could be done to make communities more resilient to climate change going forward, he shared “continued and strengthening of risk communication and preparedness plans to build awareness is critical at the area level.” That suggestion is echoed by First Nations across northwestern Ontario and is at the crux of their calls for apublic inquiry into the provincial government’s forest fire response. Boyer indicated agencies involved in the forest fire response need to continue working together, including to co-ordinate deploying fire-response teams and gear for the rest of the forest fire season. “An integrated risk management approach can help to effectively adapt to increasing severity of wildfires in Canada,” he advised. Jed Kaplan isa professor in the University of Calgary’s department of earth, energy and environment, as well as Canada Research Chair in Global System Modeling. He wasn’t involved in theImperial College London analysis, but indicated he agrees with the findings. “As long as we keep burning fossil fuels, there's going to be more and more hotter weather, which is going to lead to worse and worse wildfires,” Kaplan told CBC News on Wednesday. While people can buy air purifiers and stay inside on smoky days, “adaptation is really hard if you are in some of Canada's biggest cities, hundreds or even thousands of kilometres away from where these massive wildfires are burning in the boreal.” 'A big difference': Small fire departments in area of northwestern Ontario wildfires get new devices The longer it takes to reduce greenhouse gas emissions, the more strong conditions will become and the harder it will be to address them, shared Kaplan. Still, he feels optimistic Canada can become a global leader in decarbonizing the economy. “There are technologies out there that really can help us maintain our standard of living, even grow our economy significantly, but at the same time reduce our greenhouse gas emissions.” Sarah Law is a CBC News reporter based in the northwestern Ontario hub, Ont., and has also worked for newspapers and online publications elsewhere in the province.
