U.S. slaps 50% tariffs on Canadian goods; Ottawa vows dollar-for-dollar retaliation

The United States imposed 50% tariffs on $20 billion worth of Canadian products, covering about 5% of Canada's annual exports to the U.S., including items like hockey sticks and tongue depressors. Canada immediately announced matching retaliatory tariffs, escalating the trade conflict after last-ditch negotiations failed. The breakdown threatens the future of the USMCA trade agreement and marks a sharp reversal from earlier signs of compromise.
