<h1>Canadian leader to seek sector-specific relief from 50% Section 232 steel and aluminum tariffs in USMCA talks</h1> A Canadian leader will meet the U.S. president amid severely strained bilateral relations driven by U.S. tariffs and rhetorical threats; the meeting aims to seek sector-specific relief from 50% Section 232 steel and aluminum tariffs ahead of the USMCA review in 2026. Canada stresses that over 85% of bilateral trade remains tariff-free under USMCA but faces significant exposure given high export reliance and integrated energy, defense and critical-minerals supply chains. Legal risks include continued unilateral tariff measures, potential invocation of a six-month termination notice under USMCA, and heightened domestic political pressure if tangible tariff relief is not secured.
