Trump Blames Canada for Wildfire Smoke Choking U.S. Cities

London, United Kingdom Jul 18, 2026 ALN: A haze fell over the Capitol in Washington on Friday as smoke from Canadian wildfires stretched farther east, prompting President Donald Trump and Republican lawmakers to blame Canada for forestry practices they said were harming U.S. air quality.

Trump and congressional Republicans criticized the Canadian government for failing to manage excess timber and brush that fuels the wildfires currently burning in northern Ontario. They argued that the Canadian government is responsible for the toxic smoke affecting cities like Chicago, New York, and Washington, which led to warnings for millions of Americans to stay indoors.

“We are holding Canada responsible for the fact that they are not properly maintaining their forests and brush, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous and totally unacceptable!” Trump posted on Truth Social.

While the president laid blame on Canada, climate and public health advocates pointed out that increasingly active wildfire seasons are a consequence of climate change, particularly a record-breaking heat wave across North America. Nearly 900 fires are currently burning across Canada, with more than 150 wildfires in the U.S., including 15 in Michigan. The fine particulate matter drifting south in wildfire smoke poses significant health risks, especially for the elderly, children, and individuals with underlying health conditions.

“People want to enjoy this time of year; look up and see that blue sunny sky and certainly not struggle to breathe or see smoke coming from across the border,” said EPA Administrator Lee Zeldin in a video shared on social media.

Zeldin, along with Trump and other lawmakers, criticized Canada’s wildfire control strategy and urged them to take action to prevent wildfires from continuing to burn. “If they do not change their ways of approaching these fires, this is something that will continue to happen in the future,” Zeldin stated.

“I will call the Prime Minister during the day to find out what they are going to do about it,” Trump wrote. “The cost is incalculable! Canada has refused to engage in basic forest management and debris removal, knowing that such refusal will lead to exactly this result. This is willful negligence, and it is becoming a yearly occurrence, costing the United States billions of dollars, which must be added to the tariffs Canada is currently paying,” he added.

GOP Senator Bernie Moreno of Ohio pledged to introduce legislation next week to “sanction Canada and the responsible Canadian government officials for this atrocity,” he posted on social media.

In response, Canada emphasized its long-standing partnership with the U.S. in combating wildfires, noting that it had sent firefighters and supplies to assist with last year’s blazes in Los Angeles.

“This is a shared challenge, and it demands a shared response,” said U.S. Ambassador to Canada Pete Hoekstra in a statement. “I commend the outstanding cooperation between the United States and Canada as we confront these fires together. Our two governments are monitoring and sharing information in real time — coordination that reflects our partnership at its best.”

Emergency Management Minister Eleanor Olszewski also highlighted that “Canada and the United States have a long history of working together to fight wildfires on both sides of the border.” Since 2020, Canada has invested $12 billion in forest sustainability and fire prevention, she noted.

However, air quality has deteriorated across U.S. cities, with areas as far south as Washington receiving a “purple” air quality rating — indicating “very unhealthy” conditions, according to the EPA’s monitoring tool.

Moreno’s proposed bill would direct the president to impose financial sanctions on Canada and restrict visas for certain Canadian officials involved in government or wildfire mitigation if it is determined that Canada is not adequately managing its wildfires.

The smoke reached border-state Michigan earlier this week, prompting backlash from four Republican lawmakers — Reps. Jack Bergman, John James, Lisa McClain, and John Moolenaar — who wrote to Canadian Prime Minister Mark Carney criticizing Canada’s lack of wildfire mitigation efforts.

“We were told last year that this would be treated with urgency. It was not. We were told the causes, chronic under-investment in forest thinning, fuel reduction, and prescribed burns, along with inadequate enforcement against arson, were being addressed. They were not, or not adequately enough to matter to the people we represent,” the lawmakers wrote in their letter.

The lawmakers threatened that if Canada does not adopt new forest management practices, American federal agencies could consider “direct involvement in cross-border fuel reduction and firefighting capacity.”

Other Michigan Republicans have also suggested punitive measures to address the wildfire smoke. Rep. Tom Barrett (R-Mich.) suggested delaying the opening of the new border-crossing Gordie Howe Bridge until “Canada takes responsibility and gets control of these fires.” Rep. Bill Huizenga (R-Mich.) stated that Canada should “fully and regularly inform appropriate U.S. agencies such as the EPA about the status and mitigation action plan regarding the fires.”

Terri Deboer, a Republican candidate running for Congress in Michigan, where air quality remains at dangerous levels, criticized Canada’s failure to manage its forests. “Canada has refused to responsibly clear underbrush, manage fuel loads, and implement proactive measures to prevent these fires from escalating,” she stated in a social media post.

As smoke spread eastward later in the week, Rep. Nick Langworthy (R-N.Y.) reached out to Canadian parliament members and the ambassador regarding the smoke’s impact in New York. “Canada must take meaningful action to prevent these catastrophic wildfires and protect both Canadians and Americans. If it refuses to do so, there should be consequences,” he wrote on social media.

Record-breaking Heat Fuels Flames

Climate and health experts attribute the current wildfire conditions to climate change, particularly the recent record-breaking heat wave in North America that has dried out forests and increased the likelihood of thunderstorms and lightning strikes. Daniel Swain, a climate scientist at the California Institute for Water Resources, noted that the extreme heat experienced across North America this summer has been exacerbated by climate change.

The smoke blanket has drawn comparisons to the extreme summer of 2023, which saw record-breaking wildfires in Canada that sent smoke billowing over the eastern U.S. That year was marked as the country’s most destructive wildfire season on record, with studies indicating that climate change significantly increased the likelihood of weather conditions fueling the flames.

Warming temperatures are altering the timing and location of wildfires. While western Canada has historically faced the largest and most destructive blazes, research suggests that eastern Canada may also be at greater risk as global temperatures continue to rise.

“We’re not saying that climate change started each individual fire, but extreme heat and drier conditions in Ontario, along with increasingly likely weather patterns, are leading to more fire weather days,” said Shel Winkley, chief meteorologist at Climate Central. “All of these factors contribute to explosive wildfire growth, as we saw earlier this week.”

An analysis by Climate Central revealed that on July 13, the day the cluster of blazes in Ontario and Minnesota began, temperatures in Ontario were 25.2 degrees Fahrenheit above average. “These temperatures would be virtually impossible to occur on July 13 in Ontario without the influence of climate change,” Winkley stated.

While effective forest management can mitigate wildfire risks, Winkley emphasized that rising temperatures will likely lead to more devastating wildfires in the future.

Canada is not alone in experiencing historically active fire seasons. This year, over 5,740 square miles (14,860 square kilometers) of the U.S. have burned from wildfires, which is 31 percent more than the average for the same date over the past decade, according to the National Interagency Fire Center.

Stay Inside

Wildfire smoke poses serious risks to human health. Particulate matter from wildfire smoke affects nearly every system in the human body, contributing to tens of thousands of deaths annually, according to numerous medical studies.

Soot from wildfires is linked to increased cases of asthma, heart attacks, and other cardiovascular and lung issues, as well as mental health problems. It poses risks to pregnant women, increasing the likelihood of premature births and low-weight babies who may face lifelong breathing difficulties. Long-term exposure can also contribute to health issues, including dementia.

“We know that particle pollution is harmful, both short-term and long-term,” said Laura Kate Bender, who leads public policy at the American Lung Association. She noted that research indicates that chronic exposure to particulate pollution can lead to premature death and various health complications. However, studies are ongoing regarding the effects of high levels of PM pollution from severe wildfire events.

Bender recommended controlled burns and other measures to reduce the risk of large wildfires like those currently occurring. However, she reiterated that climate change is creating the conditions that allow these fires to ignite and spread.

“We know this is happening for wildfires in the U.S., Canada, and worldwide,” she concluded. “The conditions leading to these fires are not coincidental; they align with the changes expected from a warming climate.”
