President Trump has escalated his trade dispute with Canada after Ottawa imposed approximately $20 billion in new retaliatory tariffs on American products. Using Section 338 of the Tariff Act of 1930, Trump signed five proclamations imposing new import bans and reshuffling existing tariffs on Canadian goods. Alcohol, dairy, and vehicles feature prominently in the dispute, while some products such as cement and rock salt will be removed from existing tariff coverage. The White House frames the action as part of Trump’s broader push for reciprocal trade, domestic manufacturing, and reshoring.

- On September 8, 2026, President Donald Trump signed five proclamations responding to new Canadian retaliatory tariffs and what the White House characterizes as continued discriminatory treatment of U.S. exports.
- The White House says Canada imposed new retaliatory tariffs on roughly $20 billion in U.S. exports, including steel, dairy products, and agricultural equipment, after trade talks broke down the previous month.
- Using Section 338 of the Tariff Act of 1930, Trump imposed import bans on certain Canadian products, particularly involving alcohol and dairy, that had previously been subject to 50% tariffs.
- The administration is also altering its July 20 tariff package: products including rock salt and cement are being removed, while products including ATVs and additional dairy goods are being added.
- The Section 338 measures apply even to covered goods qualifying under USMCA, and can stack on top of tariffs imposed under Section 232.
- The product additions and removals take effect September 15, 2026. The new import bans take effect September 29, 2026.
- The administration argues the measures protect American farmers, manufacturers, and workers while pressuring Canada toward reciprocal trade terms.
- The fact sheet also cites U.S. manufacturing growth and several major domestic investments—$1.2 billion from Chobani, $1 billion from Rolls-Royce, and $1.5 billion from Octapharma—as evidence supporting Trump’s broader trade and reshoring strategy.
- Trump has additionally directed U.S. officials to remove Canadian-origin products from GSA procurement schedules that the White House says manage more than $50 billion in federal purchasing.
- The White House says Canada and China are the only two countries over the past year and a half to retaliate against Trump’s tariffs rather than negotiate an agreement.
