President-elect Donald Trump on Monday vowed to impose a 25 percent tariff on all imports from Canada and Mexico, setting off alarm bells in Ottawa and prompting Ontario Premier Doug Ford to ask Prime Minister Justin Trudeau to convene an urgent meeting of provincial leaders. The announcement escalates trade tensions just weeks after the U.S. election and raises questions about the future of North American supply chains.
Trump posted on his social feed that on Jan. 20, the first day of his new administration, he would sign “all necessary documents to charge Mexico and Canada a 25% Tariff on ALL products coming into the United States.” He cast the measure as a response to what he described as failures to curb illegal migration and the flow of fentanyl. The posts represented one of his most specific statements on trade since the election.
In Ottawa, premiers moved fast. The Council of the Federation, which represents Canada’s provincial and territorial leaders, sent a formal letter to Mr. Trudeau dated Nov. 25 requesting “a First Ministers’ Meeting as soon as possible to discuss Canada-U.S. relations.” The letter, signed by Doug Ford as chair of the council, urged a coordinated “Team Canada approach” on trade, border security, energy, defence and cross-border supply chains.
“Premiers agreed at our November 20th meeting on the need to meet urgently as First Ministers to discuss a Team Canada approach to engaging with the incoming administration,” the letter says. The request reflects worries that a broad, across-the-board tariff would hit industries from agriculture to autos and energy.
Mr. Trudeau said the country must remain united and work through channels to address the threat. He told reporters that leaders would “be all pulling together on this” as Ottawa makes plans to engage with the incoming U.S. administration.
Economists and industry groups warned the tariff threat could have immediate, measurable consequences. Canada ships the bulk of its goods to the United States — around three quarters of its exports — and the two economies are deeply integrated in sectors such as auto manufacturing and energy. Markets reacted swiftly: the Canadian dollar fell and shares in auto and other cross-border firms slipped as investors repriced trade risk. Analysts warned that steep tariffs would quickly feed into higher consumer prices on both sides of the border.
Trade experts noted the legal and political hurdles such a move would face. A blanket 25 percent duty would appear to run counter to the Canada-United States-Mexico Agreement, and could revive the tit-for-tat tariff disputes that marked an earlier bout of U.S. protectionism. That raises the prospect of rapid escalation, with Ottawa likely to weigh retaliatory measures while seeking diplomatic channels to avert a full trade conflict.
Ford, who chairs the Council of the Federation, framed the premiers’ appeal in pragmatic terms. The Nov. 25 letter asked Mr. Trudeau for clarity on how the federal government intends to include provinces in preparations for the USMCA review and who in cabinet would lead engagement with Washington. The move underscores how provincial governments — particularly resource and manufacturing provinces — are positioning themselves as stakeholders in any renegotiation or crisis planning.
What happens next is uncertain. Trump’s post set a deadline tied to his inauguration on Jan. 20. Ottawa’s immediate task is to coordinate a cross-country response and to press for a diplomatic resolution before any executive action takes effect. Canadian officials say they prefer negotiation and engagement, but they have made clear they will not hesitate to use the tools available to defend Canadian workers and industries if tariffs are imposed.
