US President Donald Trump has threatened to impose tariffs on Canada due to wildfire smoke blanketing northern US cities. Trump accused Canada of "willful negligence" for not properly managing its forests. Hundreds of wildfires are actively burning in Canada, with many out of control, impacting air quality across numerous US states and leading to hazardous air quality alerts. Canadian Prime Minister Mark Carney stated that fighting climate change, which experts link to worsening wildfire conditions, is a shared responsibility for both the US and Canada. Ontario Premier Doug Ford also suggested the US should send support rather than complain, noting Canada's past assistance with US wildfires. US lawmakers have expressed frustration with Canada's response to the fires.

Trump threatens to tariff Canada over wildfire smoke choking northern US cities 1 hour ago Share Save Add as preferred on Google Nadine Yousif,Senior Canada reporter, Marco Silva,BBC Verifyand Zahra Fatima Selcuk Acar/Anadolu via Getty Images Smoke from the massive wildfires has cast an orange haze over New York City US President Donald Trump has threatened to impose new tariffs on Canada after hundreds of wildfires have left much of the northern US choked by a blanket of smoke. The threat follows complaints by US lawmakers over the wildfires and Ontario's premier Doug Ford asking the US to send support to fight the fires, rather than complain. "The United States is being unnecessarily invaded by filthy, polluted, and unhealthy air," Trump said, threatening to impose new levies over Canada's "willful negligence". As of Friday, there were about 888 fires actively burning in Canada, according to the Canadian Wildland Fire Information System - with the majority burning out of control. More than 190 of those blazes are burning in Ontario, some out of control. Trump said in his post to Truth Social that would call Canadian Prime Minister Mark Carney to demand an explanation over his country's "willful negligence," accusing the country of "not properly maintaining" their forests and brush. Canada has not responded to the threat but Carney earlier noted that it was the responsibility of both countries to fight climate change. According to the Canadian Wildland Fire Information System, nearly 3 million hectares of land in Canada has already been destroyed by the wildfires. The impacts have been far-reaching, with a thick blanket of smoke spreading across US states, from Minnesota and Michigan to Pennsylvania, Ohio and New York. "Hazardous" air quality alerts have been issued across much of the region, leading to the cancellation of many outdoor events. As of Friday, air quality in Detroit was worst in the world, Swiss air quality tracker IQAir said, followed by the Midwestern city of Chicago, Washington DC, and New York in seventh place. The far-reaching impacts of wildfire smoke – and how to protect yourself Canada fires prompt US air quality alerts as smoke blankets major cities In the open letter addressed to Canadian officials, US lawmakers John James, John Moolenaar, Jack Bergman and Lisa McClain said their "patience has run out". "We are done accepting apologies in place of action," they said, warning the US could explore direct involvement in cross-border wildfire protection and firefighting if Canada failed to act. "We were told last year that this would be treated with urgency. It was not," they claimed, adding that instead "American lungs are paying the price for Canadian inaction, year after year". They said that issues such as "chronic under-investment in forest thinning, fuel reduction, and prescribed burns, along with inadequate enforcement against arson", had not been addressed "adequately enough". But scientists BBC Verify have spoken to say the picture is more complicated. "Weather doesn't care about international borders," says Dr Patrick James from the University of Toronto. Once smoke reaches the atmosphere, it travels wherever the winds take it - and smoke from major US wildfires has also affected Canada in recent years. Experts also say many of the current fires are burning in Canada's vast, remote forests, where fires can be difficult to detect or contain before they become too large. While better forest management can reduce wildfire risk in some areas, particularly near communities, it cannot prevent fires across an ecosystem of this scale. "Climate change is a global issue, and it would be inaccurate to suggest that Canada alone caused or could have prevented these wildfires," says Dr Anabela Bonada from the University of Waterloo. ‘You can taste the smoke’: New Yorkers on air quality as fires burn across Canada Ontario Premier Ford replied to the lawmakers on Friday, saying that Canada has helped the US battle wildfires in California and respond to hurricanes in North Carolina. "Maybe what you should do rather than complain is send support, send help, because we have done the exact same thing for our American friends," Ford said. Responding to the criticism from US lawmakers, Carney said in French during a news conference in Ontario: "Climate change is everyone's responsibility - truly everyone's - including the United States." He added that his government was "in close communication" with provinces and local communities. Meanwhile, Ford dismissed criticism of his government's handling of the fires, noting that more than 150 fire crews are on the ground battling the blazes, along with over 80 water bombers and helicopters. He added that his government has spent more than a billion dollars on wild land fire since 2018, and routinely spends more than its base budget allocated annually for firefighting due to the need. "We are throwing every single resource we can," he said. America's blame game over Canada's wildfire smoke misses the point, experts say A large cluster of fires affecting northwestern areas of Ontario are responsible for sending thick plumes of smoke and poor air quality across the region and into the US. On Thursday, thick haze of smoke blocked views across New York City, including the Empire State Building and the Statue of Liberty. Likewise, national monuments across Washington DC were obstructed by the hazy conditions. Officials have stressed for people to stay indoors, some areas even passing out free masks, due to the poor health impacts of inhaling the fumes. It's led to outdoor activities being cancelled across the northern parts of the US, from Chicago and Detroit to parts of Pennsylvania and New England. Summertime camps were brought indoors, concerts were rescheduled - and at least one beach was shuttered along a popular lake. The inclement weather has also sparked concerns around Sunday's World Cup final between Argentina and Spain at MetLife Stadium - an open-air venue - in New Jersey, where Trump is due to attend. White House officials - including Andrew Giuliani, the head of the White House's World Cup task force - is holding informal meetings with Fifa officials and others monitoring the wildfires, but no larger, formal meeting has so far been planned. Forecasters believe that rains in the area over the weekend will improve conditions before the two teams take the pitch at 1500e (2000 BST). In addition to the hazardous smoke extending across to the US, wildfires in northern Ontario have forced dozens from local First Nations communities to evacuate, with videos showing some fleeing the remote area by boat. Members of the Namaygoosisagagun First Nation in the northern part of the province say they are "distraught" after fires tore through the community with very little warning. Namaygoosisagagun First Nation Chief Helen Paavola told local news outlet CityNews in an interview that an aerial flyover showed that her community has been "burnt to ashes". Ford said a total of 10 communities have had to evacuate, with many now seeking refuge in southern Ontario cities. "It's a miracle that no one lost their lives," the premier said.
