Canadian Prime Minister Mark Carney announced Tuesday that Canada will implement retaliatory tariffs against the United States, escalating a trade dispute that has seen negotiations collapse. Carney accused Washington of attempting to subordinate Canada and stated that the nation must fight back against what he described as a "bullying" approach from U.S. President Donald Trump.

"You're at war when you're attacked, and we got attacked," Carney told Canadians. "We're going to hit back." The prime minister's office indicated that the new tariffs would target U.S. goods including steel, dairy, and agricultural equipment, set to take effect on September 8.

The trade talks between the U.S. and Canada broke down Friday when Carney withdrew from negotiations just hours before Trump's proposed 50 percent tariffs on $20 billion worth of Canadian goods were scheduled to be implemented. Trump responded Monday via social media, asserting that Canada had been "ripping off the United States for years" and that "WE DON'T NEED CANADA, THEY NEED US!"

Carney suggested that Canada might move away from matching U.S. tariffs dollar-for-dollar, opting instead for more targeted retaliation designed to protect Canadian workers and businesses. He characterized the U.S. negotiating stance as one where "Canada is a subsidiary of the United States," an attitude he deemed unacceptable. He further stated that American proposals regarding the auto industry would lead to the dismantling of Canadian production.

"The Americans want to destroy our major industries, including autos, steel and aluminum," Carney said, explaining his decision to reject the deal. "That was one of the main reasons we said no. It was a bad deal."

Ontario Premier Doug Ford also voiced strong opposition, telling Trump to "kiss my a**" and threatening to cut off electricity exports to the U.S. in response to the tariffs. "We power 1.5 million homes and businesses," Ford stated. "Everything's on the table. I'll do whatever it takes."

Trump, in turn, attacked Ford personally on social media and reiterated his view of Canada's trade practices. Vice President JD Vance also commented, referring to Canada as "a state" and criticizing its trade policies.

Canada and the United States share one of the world's most significant trading relationships, with highly integrated supply chains in sectors like automotive, energy, agriculture, and manufacturing. A prolonged trade conflict could impose substantial costs on businesses and workers on both sides of the border.

U.S. Trade Representative Jamieson Greer stated that Canada's auto industry exists due to the 1960s Auto Pact. However, Carney expressed doubt about U.S. dependability, noting Canada was finding reliable partners globally, with the exception of the United States and Russia.

Despite political differences between Carney, a Liberal, and Ford, a Progressive Conservative, their unified stance reflects broad Canadian consensus on the trade dispute. Ford indicated that critical minerals, essential for U.S. national security and manufacturing, and oil and potash, could also be part of retaliatory measures, along with electricity pricing.

Ford accused the Trump administration of aiming to dismantle Canadian industries rather than secure a better trade deal. He also noted U.S. demands late in negotiations that sought to restrict Canada's ability to form trade agreements with other countries without U.S. approval, which Carney deemed unacceptable and a matter of Canadian sovereignty.

Negotiations had reportedly been ongoing for about a month before collapsing. Trump had extended the negotiating window, but the extension ultimately failed to yield an agreement, with both nations blaming the other. U.S. officials cited new Canadian demands and walk-backs of previous commitments, while Canada pointed to shifting U.S. demands. The heightened tensions come as economic concerns are increasingly prominent in U.S. politics ahead of the midterm elections.
