U.S. President Donald J. Trump has imposed sweeping new 50% tariffs on a broad range of Canadian imports, accusing Canada of unfairly discriminating against American products and failing to provide equal access to the Canadian market.
In a fact sheet released by the White House on July 20, Trump announced he had signed three proclamations under Section 338 of the Tariff Act of 1930, imposing the additional duties on selected Canadian goods, including products ranging from wine and hockey sticks to cement.
The White House said the tariffs are intended to counter what it described as Canada’s “discriminatory treatment of American products” and to “offset the burden and disadvantage on U.S. commerce” while “leveling the playing field” for key American exports such as automobiles, alcohol and dairy products.
The new tariffs will apply regardless of whether the goods qualify under the United States-Mexico-Canada Agreement (USMCA) and are scheduled to take effect 30 days after the proclamations were signed. However, the measures will exempt energy products, potash, goods already subject to Section 232 tariffs, fish, critical minerals and certain other products.
According to the White House, the action was prompted by what it described as Canada’s continued “discrimination against and unreasonable and unequal treatment of U.S. commerce.”
The administration pointed to Canada’s automotive import quotas, arguing they favour imports from other countries while encouraging American manufacturers to shift production north of the border. It said Canadian imports of U.S. motor vehicles fell by approximately 22%, or $5.6 billion, between April 2025 and March 2026, compared with the previous year, while imports from other countries increased.
The White House also cited restrictions on American alcoholic beverages, noting that all but two Canadian provinces and territories have halted the purchase, distribution or retail sale of U.S. alcohol without imposing similar restrictions on products from other countries. As a result, imports of U.S. alcoholic beverages reportedly declined by 81%, or $582 million, between March 2025 and February 2026.
Trump’s administration further criticised Canada’s dairy import system, arguing that tariff-rate quotas for U.S. cheese are more restrictive than those applied to cheese imported from the European Union.
The White House said Section 338 authorises the President to impose tariffs when another country disadvantages U.S. exporters relative to exporters from third countries.
The administration also noted that, over the past 18 months, only China and Canada had chosen to retaliate against U.S. tariffs instead of negotiating new trade arrangements with Washington.
The latest measures form part of Trump’s broader America First Trade Policy, which the White House says is designed to expand market access for U.S. exports, strengthen American manufacturing, reduce the trade deficit and protect national security.
The administration said the United States declined to renew the USMCA in its current form because it no longer considers the agreement sufficiently beneficial to American interests.
According to the White House, Trump’s tariff strategy has already resulted in 18 trade agreements, secured trillions of dollars in private and foreign investment, and contributed to continued growth in U.S. manufacturing, which it said expanded for a sixth consecutive month in June 2026.
