Climate Crisis-Denying Trump Threatens Canada With New Tariffs Over Wildfire Smoke

A day after a Republican senator pledged to introduce legislation sanctioning Canada for the wildfire smoke impacting various US communities this week, President Donald Trump on Friday threatened the United States' northern neighbor with new tariffs.

"We are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush therein, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable!" Trump wrote on his Truth Social platform. "I will call the Prime Minister during the day to find out what they are going to do about it."

"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," Trump continued. "This is Willful Negligence, and becoming a yearly occurrence, costing the United States Billions of Dollars, which cost of this pollution must of necessity be added to the TARIFFS Canada is currently paying."

Melanie D'Arrigo, a campaigner for single-payer healthcare in the United States, responded, "So can Canada hold US oil companies, their lobbyists, and the congresspeople they bribe for the climate crisis that increases droughts and the risk of these wildfires?"

"When Trump talks about increasing tariffs on Canada, he's talking about Americans paying more for the things they need—because the increased costs are paid by American consumers," she also stressed.

According to the Canadian Broadcasting Corporation, when asked for a comment on Trump's post, a spokesperson for Canada's Embassy in Washington, DC only said Ambassador Mark Wiseman has "engaged directly with key administration and Hill officials regarding the wildfire emergency in Canada, our efforts to address it, and the impact of wildfire smoke on Canada and the US."

CBC noted that a day earlier, four Michigan Republicans in the US House of Representatives had made similar statements in a letter to Prime Minister Mark Carney, who didn't address the missive when asked about it, but told reporters in French that "climate change is everyone's responsibility—truly everyone's—including the United States."

Big Oil-backed Trump has notably rejected scientific conclusions about the fossil fuel-driven climate emergency on the world stage and, throughout both terms, made various policy decisions that serve industry polluters—even as his own government continues to publish climate science.

While Carney has publicly embraced climate science, the Liberal leader has also recently faced criticism for "pouring fuel on the flames of the climate emergency" by "expanding tar sands and the fracked gas industry."

Meanwhile, the fires raging across Canada—and prompting air quality alerts across the US Midwest and Northwest—have spurred calls for "Nuremberg trials for Big Oil," given that the burning of fossil fuels has made the blazes more extreme and frequent.

Despite the science, Republicans on Capitol Hill seem hell-bent on strictly blaming Canadian forest management. Sen. Bernie Moreno (R-Ohio), a key ally of Trump and the fossil fuel industry, said Thursday on the social media platform X that "I'll be introducing a bill next week to sanction Canada and the responsible Canadian government officials for this atrocity."

Replying to the post, climate reporter Kate Aronoff wrote that a "major function of this site during climate-fueled disasters now is providing a space for right-wingers to beta test increasingly insane talking points for avoiding the obvious."

More Perfect Union producer Jordan Zakarin also fired back on X, writing, "The United States sanctioning another country, much less Canada, for pollution and environmental destruction is the stuff of bad satire."

Fossil Free Media director Jamie Henn said, "How about sanctioning the companies fueling the climate crisis that’s making these fires more frequent and intense?"

Democrats in Washington, DC "should introduce a Make Polluters Pay bill that taxes oil and gas companies' record profits and uses the revenue for wildfire relief, air purifiers, and all the adaptations we need to... deal with these climate disasters they helped create," he proposed.

Sen. Bernie Sanders, a Vermont Independent who caucuses with Democrats, also took aim at Republican climate lies in a lengthy social media post on Thursday, noting that "in both the United States and Canada, this heat and drought is driving longer and more intense wildfire seasons, including the more than 800 wildfires across Canada and northern Minnesota that are currently causing dangerous levels of air pollution for at least 115 million people across 20 states."

"NO, Mr. President: Climate change is not a hoax. It is reality. And your ignorance is putting our kids and grandkids at risk in exchange for the short-term profit of your billionaire friends in Big Oil," Sanders said. "Our job: Reject President Trump's lies and take on the crisis of climate change and the greed of the fossil fuel industry by transitioning our energy system to energy efficiency and sustainable forms of power. When we do that, we cut carbon emissions, reduce energy bills, and create millions of good union jobs."

Cassidy DiPaola, communications director for the Make Polluters Pay campaign, charged that "blaming Canada for these wildfires is like blaming a homeowner when an arsonist sets their house on fire. Canada is choking on the same smoke we are, and sanctioning our closest ally doesn't clear a single acre of burned forest or stop the next fire from starting."

"If Republicans actually wanted to hold someone responsible, they'd go after the fossil fuel companies whose executives knew what their products were doing to the planet and buried the science anyway," she argued. "Instead, Congress is moving in the opposite direction, weighing legislation that would grant the fossil fuel industry total immunity from climate liability. And if Republicans wanted policies that actually protect their constituents' health, they'd support climate superfund bills that fund public health programs, help wildfire survivors rebuild, and prepare communities for the risks still ahead."

Moreno's bill, she added, "is a shameless attempt to make sure the blame lands anywhere but on the fossil fuel industry, and everyday Americans will pay the price for that misdirection while the companies that caused this crisis walk away untouched."
