On Tuesday, July 21st, 2026, President Donald Trump announced plans to impose 50% tariffs on a broad range of Canadian imports to the United States, including hockey equipment and alcoholic beverages. These new tariffs, formalized through a series of proclamations signed by the president, mark an escalation in the ongoing trade dispute between the two neighboring countries.

The White House accused Canada of "unreasonable, unequal, and discriminatory actions" by imposing tariffs or import restrictions on certain American goods, some of which began after the previous year's Canadian tariffs on U.S. auto imports. In retaliation, the Trump administration had already imposed tariffs on Canadian electronics, honey, flower bulbs, plywood, cowhides, jewelry, and more. The latest tariffs also target Canadian beer, wine, liquor, and milk, responding to Canadian boycotts of U.S. alcohol and longstanding Canadian dairy import quotas.

These tariffs are based on Section 338 of the 1930 Smoot-Hawley tariff act, a law historically linked to worsening the Great Depression. However, Philip Zelikow of the Hoover Institution noted that Section 338 was superseded by legislation enacted in 1962 and 1974 and is therefore considered defunct. This raises questions about the legal basis for the tariffs, especially given that other Trump-era tariffs under the International Emergency Economic Powers Act were struck down by the Supreme Court earlier this year, and Section 122 tariffs were invalidated by the U.S. Court of International Trade.

The tariffs affect goods traded under the U.S.-Mexico-Canada Agreement (USMCA), a trade deal negotiated during Trump's previous administration. The move continues a pattern of contentious trade measures, including threats to impose tariffs in response to wildfires in Canada.
