Canada’s chief trade negotiator for the United States said bilateral trade talks collapsed because the U.S. introduced last-minute demands not in the original framework.

The breakdown threatens the stability of North American commerce and signals a deepening rift in the diplomatic relationship between Ottawa and Washington.

Janice Charette said the impasse occurred after the U.S. imposed new, politically driven demands that Canada could not accept. The negotiations had been ongoing for roughly 10 weeks [2] before the collapse. Charette said the talks fell apart during the week of March 12-18, 2025 [1].

"The United States came to the table with a set of demands that were not on the agenda when we started negotiations," Charette said during an interview with the Canadian program “The House” [1].

U.S. officials have denied these allegations. Katherine Tai, the U.S. Trade Representative, said that the issues were raised early and Canada was aware of them [3]. Tai said the U.S. never made any last-minute demands [3].

The disagreement over the timeline and nature of the demands created a deadlock that ended the bilateral process. Following the collapse, an unnamed former U.S. trade negotiator said Washington would turn its attention to Mexico to secure a deal [3].

The dispute highlights the friction between the two nations as they struggle to align their economic priorities. While Charette points to unexpected shifts in the U.S. position, the U.S. maintains that the framework remained consistent throughout the process.

"The United States came to the table with a set of demands that were not on the agenda."

The collapse of these talks indicates a breakdown in trust between the primary trade partners of North America. By shifting focus to Mexico, the U.S. may be attempting to isolate Canada or create leverage to force Ottawa to accept the disputed terms. This diplomatic impasse leaves Canada vulnerable to economic volatility while its neighbor seeks alternative regional alignments.
