Trump Slaps 50% Tariffs on Nearly $20 Billion in Canadian Imports Under Rarely Used Statute

On July 20, 2026, President Trump signed three proclamations imposing 50% ad valorem tariffs on nearly $20 billion in Canadian imports — including motor vehicles, wine, and hockey sticks — under Section 338 of the Tariff Act of 1930. The tariffs take effect August 19. Energy, potash, fish, and critical minerals are excluded. USTR cited Canada's discriminatory treatment of U.S. exports.
