US Imposes 50% Tariffs on Canadian Goods After Trade Talks Collapse

The United States imposed sweeping new tariffs on Canadian goods after trade negotiations between the two countries collapsed, prompting Ottawa to announce retaliatory measures set to take effect next month. The 50% tariffs, covering approximately $20 billion worth of Canadian exports, went into effect on August 23, 2026, following the breakdown of talks late the previous day. Canadian Prime Minister Mark Carney confirmed his government would respond with dollar-for-dollar retaliatory tariffs beginning September 8. The talks fell apart over several sticking points, with the U.S. presenting new proposals at the last minute that Canada rejected.
