Trump tightens trade measures against Canada with new bans and tariff changes
The White House said Donald Trump signed five proclamations to restrict Canadian products and revise the framework announced in July. The move was presented as a response to new Canadian tariffs on U.S. exports.
Donald Trump signed five proclamations under Section 338 of the Tariff Act of 1930 to bar certain products from Canada and change the scope of tariffs on other Canadian goods, according to the White House.
The official statement said the move came after Canada imposed new retaliatory tariffs on about $20 billion in U.S. exports, including steel, dairy, and agricultural equipment. The White House also said Ottawa had broken off trade talks with Washington last month.
According to the administration, the new restrictions cover certain Canadian alcoholic beverages and dairy products, in response to what it described as discriminatory treatment of U.S. alcohol and dairy exports. The government also decided to revise the measures announced on July 20, 2026: some products, including rock salt and cement, will be removed from the Section 338 tariff list, while new ones will be added, ranging from all-terrain vehicles to additional dairy products.
The White House said the Section 338 tariffs will apply to all covered goods regardless of whether they qualify under the U.S.-Mexico-Canada Agreement, and that they will be imposed on top of tariffs already in place under Section 232 of the Trade Expansion Act of 1962.
According to the statement, the import bans will take effect on September 29, 2026, while the product additions and removals will take effect on September 15, 2026.
In the same document, the White House framed the action as part of the America First trade policy and said Trump also directed the Office of the United States Trade Representative and the General Services Administration to remove Canadian-origin products from federal purchasing schedules.
