Trump's Mexico side deal cannot rewrite CUSMA without Canada's signature

Summary

Formal Canada-U.S. trade talks collapsed on August 21st, and there have been no formal meetings since. The day before, Mark Carney and Claudia Sheinbaum had agreed by phone that CUSMA should be renewed quickly. Meanwhile, the United States and Mexico have completed three formal negotiating rounds, with a fourth expected this month.

The video describes the U.S.-Mexico arrangement as a thin, preliminary bilateral deal. Mexico would receive tariff relief in exchange for domestic policy changes and closer alignment with American trade policy toward non-market economies. Experts quoted in the video say it would sit beside CUSMA rather than replace it. The bigger worry for Canadian auto workers is Section 232 tariffs: the current U.S. auto tariff is 25%, and Mexico may negotiate it down to 15% or lower, a figure that could become a baseline for Canada.

The video's central argument is that CUSMA cannot be rewritten without Canada. Any change requires the concurrence of all three countries, which gives Ottawa an effective veto. The video also argues Canada did much of its groundwork early and could return to the table close to Mexico's position. It points to a new Mexico-Canada channel and suggests that a divide-and-conquer strategy runs out of road at the treaty level.
