Trade negotiations between Canada and the United States have collapsed, leading to the imposition of 50% tariffs on nearly $28 billion worth of Canadian imports. The United States announced the tariffs would take effect at midnight, prompting Canada to vow retaliatory measures dollar-for-dollar. The breakdown follows a year and a half of stalled talks, with repeated glimmers of progress dashed. Canadian businesses now face increased costs and uncertainty as the new tariffs are applied. Prime Minister Justin Trudeau’s government has threatened to impose its own retaliatory tariffs, which will come into force the Tuesday after Labor Day. The dispute has sparked public frustration, with soccer fans in Vancouver and Montreal booing the American national anthem during matches. The trade representative for the United States, Jamieson Greer, had previously outlined the U.S. Offer to Canada, which was rejected. The ongoing trade conflict highlights deepening tensions between the two nations, with both sides preparing for economic retaliation.
