U.S. Trade Representative Jamieson Greer said Monday that Canada is responsible for the collapse of tariff negotiations between the two nations [1].
The failure of these talks threatens the stability of one of the world's largest trading relationships and could lead to increased costs for consumers and manufacturers in both countries.
Speaking on CNBC’s “Squawk Box,” Greer said the negotiations broke down because Canada "wanted more" [2]. He said that Canada changed its demands in the final hours of negotiations [3]. According to Greer, these last-minute alterations caused the agreement to fail [1].
The breakdown occurred after a critical period of 72 hours [4]. While U.S. officials point to Canadian volatility, Canadian leadership offers a different account of the events. Canadian Prime Minister Mark Carney said, "We got attacked" [5].
The disagreement highlights a sharp divide in how each government views the final stages of the talks. U.S. sources said that the Canadian side shifted its requirements at the eleventh hour [3]. Conversely, Canadian officials said that the United States was the party that changed the deal or initiated the conflict [5].
This collapse follows weeks of effort to resolve tariff disputes. The two countries have historically maintained deep economic integration, but the current impasse suggests a period of heightened trade tension. Greer said he did not specify exactly which demands were changed, only that the shift in expectations made a deal impossible [2].
“"They wanted more."”
The conflicting narratives between Jamieson Greer and Mark Carney indicate a significant diplomatic rift. When both nations blame the other for a collapse in the final 72 hours, it suggests a lack of trust that may complicate future attempts to renegotiate tariffs. This instability could lead to market volatility for industries dependent on cross-border trade.
