U.S. President Donald Trump has signed an executive order imposing a sweeping 25 per cent tariff on all automobile imports to the United States, triggering immediate concern and backlash across Canada. The tariffs, set to begin April 2, are the latest move in Trump’s aggressive trade agenda, which he has dubbed “Liberation Day” for American manufacturing. While the White House insists vehicles under the Canada-U.S.-Mexico Agreement (CUSMA) will only be taxed on non-U.S. content, confusion remains over how and when these duties will impact the deeply integrated North American auto industry.
Canadian Prime Minister Mark Carney called the move a “direct attack” on Canada’s auto sector and promised swift retaliatory measures. Speaking from Kitchener, Ontario, Carney emphasized Canada’s commitment to defending its workers, companies, and sovereignty. He denounced the tariffs as a violation of CUSMA and the longstanding Auto Pact that dates back to 1965. Carney also noted that the temporary exemption based on non-U.S. content calculations still leaves Canadian manufacturers vulnerable to uncertainty and potential disruption.
The auto industry responded swiftly to the announcement. Stocks for major American automakers, including Stellantis, Ford, General Motors, and Tesla, all dropped in after-hours trading. Trump offered no long-term exemptions for CUSMA-compliant vehicles and insisted the tariffs were permanent, pushing automakers to relocate parts divisions back to the U.S. Conservative Leader Pierre Poilievre criticized the president’s erratic policies, calling on Trump to “knock it off” and stop destabilizing both economies. NDP Leader Jagmeet Singh blamed the Carney government for not reconvening Parliament earlier to provide emergency support for workers facing possible layoffs.
On the ground, the uncertainty is palpable. Dave McDowell, an autoworker and Unifor Local 1859 president, shared concerns about future layoffs and slowed production at Ontario plants. Unifor national president Lana Payne echoed that sentiment, declaring Canadian auto jobs are not Trump’s to “steal.” The looming tariffs follow a string of recent trade shocks from Washington, including earlier steel and aluminum tariffs and partially paused economy-wide duties linked to fentanyl imports.
Ontario Premier Doug Ford, who had previously received assurances from U.S. officials that no further trade surprises were coming, reacted with frustration. Calling the move another blindside, Ford urged a national meeting with all Canadian premiers to prepare a united response. He warned that Canada cannot afford to simply “roll over” and must fight back with resolve. With just weeks before Canada’s federal election, Trump’s tariffs are quickly becoming a central campaign issue, turning trade tensions into a test of national resolve and political leadership.
