Mark Carney said President Donald Trump's newly announced tariffs on certain goods are a direct violation of the Canada-US-Mexico Agreement [1].

The dispute threatens the stability of North American trade relations and could lead to significant economic friction between Canada and the U.S. Because CUSMA governs the flow of billions of dollars in goods, any breach of its terms may trigger formal legal challenges or retaliatory measures.

Speaking in Ottawa this week, Carney said the move was a "violation of our agreement" [2]. The Trump administration has announced a tariff rate of 50 percent [1] on specific imports. Carney said these levies breach the established terms of the trade pact between Canada, the U.S., and Mexico [1].

Carney said that he spoke with President Trump on Tuesday morning [3]. During that conversation, the two parties reportedly agreed to intensify negotiations [3]. This diplomatic outreach comes as Canadian officials assess the potential impact of the tariffs on domestic industries.

"Direct violation of trade deal," Carney said [1].

While some reports indicated Carney spoke out on Monday, other sources place the remarks during a press briefing in Ottawa on Tuesday [1, 3]. The tension highlights the volatility of current trade policy and the precarious nature of the CUSMA framework under the current U.S. administration.

"We agreed to intensify negotiations," Carney said [3].

Direct violation of trade deal.

The clash over the 50% tariff marks a significant escalation in trade tensions between Canada and the U.S. By framing the tariffs as a violation of CUSMA, Canada is signaling that it views the move not merely as a policy shift, but as a legal breach of a binding international treaty. The agreement to intensify negotiations suggests a preference for a diplomatic resolution over immediate litigation, though the severity of the tariff rate leaves little room for minor concessions.
