Rationale

US imposed 50% tariffs on Canadian steel/aluminum via Section 232 on March 12, 2026. Canada retaliated with $29.8B in counter-tariffs on March 13. Supreme Court struck down IEEPA tariffs in Feb 2026 but Trump pivoted to Section 232. CUSMA review targeted July 1. GDP impact estimated at -1.5 to -2%. Households absorbing $1,700-$2,000/year in higher costs.
