Prime Minister Mark Carney announced that trade negotiations between Canada and the United States collapsed after Washington made unacceptable demands, plunging the historic allies into an active trade war with billions in new tariffs taking effect. According to Prime Minister Carney, speaking at a press conference in Ottawa, Canada was attacked when the U.S. imposed heavy import duties, prompting Ottawa to implement retaliatory economic penalties across multiple domestic sectors.
Trade War Escalation and New Tariffs Between the U.S. and Canada
The breakdown in trade talks led both nations to implement sweeping retaliatory tariffs on cross-border commerce. In response, Prime Minister Carney announced that Canada set Sept. 8 as the start of its retaliatory penalties targeting industries exposed to American duties, including steel products, dairy, appliances, agricultural equipment, pulp and paper, and electronics.

U.S. chief trade negotiator Jamieson Greer defended the measures, stating that the U.S. was compelled to act after a year of retaliation by its longtime partner. Conversely, Carney accused Washington of utilizing economic integration as a weapon and remarked that its signature was written in pencil. When asked by a reporter about the combative tone of his announcements, Carney stated that Canada had been attacked, asserting that you’re at war when you get attacked.
Unacceptable Demands and Failed Negotiations
Negotiations collapsed late Friday after officials from both countries failed to bridge significant gaps. Prime Minister Carney walked away from the proposed deal, doing what few other leaders have done: dared Trump and the U.S. to test his nation’s resolve.

According to a person who worked alongside him during his tenure as UN special envoy for climate action in 2021, Carney combines strict analytical discipline with an unwavering refusal to back down from difficult adversaries.
