Wildfires burning across Northern Ontario are forcing communities from their homes and pushing thick smoke hundreds of kilometres south, all the way to Toronto. The fires, fuelled by hot and dry conditions, have turned a routine summer week into an emergency across a wide stretch of the province, with the effects now felt far beyond the remote areas where the flames are actually burning.
One of the most dramatic scenes came near the community of Armstrong, where video shot from inside a CN Rail train captured flames closing in on the tracks. The footage shows fire pressing toward the train, with one voice warning that it could potentially overtake them. The crew reportedly abandoned the train and escaped on foot, leaving the locomotive behind as the fire advanced through the area.
CN Rail has since temporarily suspended operations near Armstrong because of the wildfires. The company says all of its crew members in the area have been evacuated, prioritising the safety of its staff over the movement of trains. The suspension underlines how the fires are not only threatening residents but also disrupting the rail links that serve Ontario's remote north.
Armstrong is far from alone in facing the threat. It is one of six communities in Northwest Ontario currently placed under wildfire evacuation orders, a sign of how widely the fires have spread. For those living in the region, the orders mean leaving homes behind with little certainty about when it will be safe to return, as crews continue to battle the flames.
Hundreds of kilometres to the south, the consequences arrived in the form of a heavy, smoky haze hanging over Toronto. The city landed one of the worst air quality rankings among more than one hundred large cities tracked by a website that monitors air pollution. Along the waterfront, where people would normally see clearly across to the islands, sailboats and buildings, the view was largely swallowed by the murk.
Environment Canada responded by raising its air quality warning for the area from yellow to orange. The agency urged particular caution for pregnant people, young children, older adults and anyone with pre-existing conditions, encouraging residents to limit their time outdoors. Some residents said they had donned N95 masks simply to walk to work, tasting and smelling the smoke as they went.
The situation is made worse by the combination of hazards. The smoke has layered on top of an existing heat warning, and officials note that when prolonged heat is combined with wildfire smoke, air quality can deteriorate even further. Forecasters expect the smoke to ebb and flow over the coming days, making it difficult to predict exactly when and where it will settle at ground level, where people breathe it in.
As the fires intensified, the evacuation effort reached deeper into the north. Among the communities being cleared is Gull Bay First Nation, whose residents are now being flown all the way to Toronto after Thunder Bay, the region's largest hub, ran out of room to shelter the growing number of evacuees. Thunder Bay itself endured some of the worst of the smoke, with residents describing a haze so thick they could taste it as burnt pine needles and ash drifted down into the community.
The scale of the crisis has now drawn in the federal government. With roughly 150 wildfires burning across Ontario, the province has issued a formal request to the federal government for assistance, a step that officials said could include the deployment of the Canadian Armed Forces to help with the response. The Prime Minister said the previous night that his government was in close contact with provincial, municipal and Indigenous partners and stood ready to provide additional support as needed.
The situation on the ground has continued to deteriorate. Officials said more than 170 fires were now burning across Ontario, 134 of them in the northwest, several having grown significantly over the previous 24 hours amid persistent dry and windy conditions with gusts of up to 40 kilometres an hour fanning the flames. Evacuation orders were in place for several First Nations, including Whitesand, Gull Bay and Collins, and one First Nation community north of Thunder Bay had been completely destroyed by fire. Thunder Bay itself was not under an evacuation order, but residents were urged to pack a 72-hour bag in case they suddenly needed to leave, even as the city continued to serve as a hub for evacuees drawn from more than half a dozen communities.
Toronto has said it will open its doors to those forced from their homes, with the mayor pledging that the city will find the capacity to accommodate the evacuees and noting that Toronto Public Health is on standby to support them. With more than 800 wildfires now burning across Canada, the strain of a punishing fire season is being felt from remote First Nations in the northwest to the country's largest city, where officials shuttered outdoor pools and shifted youth programs indoors to shield residents from the smoke.
