The U.S. Trade Representative (USTR) Jamieson Greer says tariff talks with Canada fail because Canada changed its demands late in negotiations. Greer tells reporters that Canada “wanted more,” arguing that Ottawa adjusted its position in the final hours rather than accepting the proposed terms.

Canada presents a different account. Canadian officials, including the prime minister, blame the U.S. for introducing new demands at the last minute. According to this view, Washington’s late changes prevent the two sides from reaching an agreement.

Across the coverage, both sides describe the breakdown as driven by end-stage negotiation tactics, but they disagree on who made the late adjustments. The dispute centers on whether the final round of bargaining involved shifting Canadian requirements or newly added U.S. requirements, leaving no shared explanation for why the talks end without a deal.
