Prime Minister Mark Carney said Canada is "at war" with the United States after trade negotiations between the two nations collapsed on Aug. 22 [1, 2, 3].
The breakdown of the tentative trade deal threatens one of the world's largest bilateral trading relationships and signals a period of intense economic volatility for both countries.
Speaking at a press conference in Ottawa, Carney said the U.S. attacked Canada economically by walking away from the agreement [1, 4]. The collapse occurred less than one hour before the established deadline [5]. Carney said the failed negotiations were a necessary break, saying, "We walked away from a bad deal" [2].
In response to U.S. tariffs, Canada will impose dollar-for-dollar retaliatory tariffs on U.S. goods [3, 4]. These measures are designed to match the value of Canadian dollars for every U.S. dollar of imports affected [3].
Carney said these retaliatory tariffs will begin in September [3, 4]. He said the current diplomatic climate is a state of conflict, saying, "You’re at war when you get attacked" [1].
The dispute follows warnings regarding economic coercion and tests the resolve of the Canadian government against U.S. trade pressure [4]. While some reports initially identified Carney as the finance minister, official communications from the press conference in the capital identified him as the Prime Minister [1, 3].
“"You’re at war when you get attacked."”
The shift toward retaliatory tariffs marks a departure from traditional diplomatic resolution between Canada and the U.S. By implementing a 1:1 tariff match, Canada is attempting to create symmetrical economic pressure to force a return to the negotiating table, though such moves typically increase costs for consumers and disrupt integrated supply chains in the short term.
