Why Trump’s New Tariff Is Bigger Than Canada | Diving In

Jul 21, 2026 · 21m

Summary

Justin Wolfers analyzes President Trump’s new 50% tariffs on Canadian goods, arguing they serve as a warning to global partners rather than addressing specific trade disputes. By invoking obscure 1930 laws to bypass the USMCA, the administration signals that retaliation will be punished, undermining trade agreement stability. Wolfers estimates modest costs for US households but significant economic and diplomatic damage for Canada, framing this as a test case for an escalating global trade war.
