Trade negotiations between Canada and the United States have failed, leading to a commitment from Canadian Prime Minister Mark Carney to mirror newly imposed US tariffs. The breakdown occurred after a three-day extension aimed at reaching a trade agreement. Carney accused Washington of introducing “unfair” and “uneconomic” last-minute changes to the proposed deal, raising concerns about the US’s negotiating reliability. He vowed Canada will respond with “dollar for dollar” tariffs, escalating the trade dispute. The failed talks signal a significant setback for cross-border commerce and potentially wider economic repercussions. Canadian officials expressed disappointment, stating they engaged in good faith throughout the process. Further details on specific tariff implementation are expected soon.
