Trump threatens 50% tariffs on Canadian autos and steel amid trade dispute

President Donald Trump announced on Monday that, beginning Jan. 1, 2027, the United States will levy 50% tariffs on imported Canadian automobiles, trucks, automobile parts and steel. The proposal follows a breakdown in trade talks between Washington and Ottawa, after Canadian Prime Minister Mark Carney said the United States had presented "uneconomic" and "unfair" terms.

Carney responded that Canada will match Washington's new tariffs dollar for dollar to protect Canadian workers and businesses. Ontario Premier Doug Ford said Canada is prepared to consider additional steps, including limiting electricity flows and restricting critical mineral exports.

U.S. Trade Representative Jamieson Greer told CNBC that the tariffs affect a small portion of trade and avoided labeling the measures a "trade war." Current U.S. tariffs on Canadian steel already stand at 50%, and Canadian-made vehicles that do not meet USMCA requirements face a 25% tariff. It remains unclear whether the new announcement will double the steel tariff.

Analysts note that higher duties on autos and parts could disrupt the integrated North American automotive supply chain and pose challenges for the USMCA agreement signed during Trump's first term.
