In a significant escalation of the ongoing trade disputes, negotiations between the U.S. and Canada have collapsed, resulting in the U.S. imposing 50% tariffs on $20 billion worth of Canadian goods. Canadian officials, including Mark Carney, have vowed to retaliate dollar for dollar against these tariffs. The breakdown in talks comes just before a critical deadline, reigniting tensions between the two nations. Both countries continue to hold their positions, with U.S. officials previously circulating draft texts for a potential deal, but ultimately no agreement was reached. As the NATO allies brace for the economic fallout, Canadian business leaders prepare for the impacts of these new tariffs.
