Sources
Methodology Note: This analysis is based on three sources available at the time of writing, concerning the joint review of the USMCA on July 1, 2026; the U.S. refusal to renew the agreement as announced by Jamieson Greer; the official letter from Dominic LeBlanc requesting a 16-year extension; and the shift to a system of annual reviews through 2036. The U.S. sector-specific tariffs mentioned (steel, aluminum, automobiles, kitchen cabinets) are documented by these same sources. Important limitation: The 50% tariff episode reported by the French press on August 22, 2026, and the response attributed to Mark Carney could not be verified in any publicly available document and are therefore not addressed in this text. Investment mechanisms in a context of uncertainty are presented as plausible scenarios, not as quantified causal relationships for the Canadian case.
