A bitter dispute between the U.S. and Canada over trade practices has escalated into what some economists warn could be a full-blown economic conflict, with both nations imposing retaliatory tariffs on key industries. American farmers, particularly dairy producers, face steep penalties under Canadian measures targeting subsidized goods, while Canadian lumber and steel sectors are now under heavy U.S. tariffs. Experts caution that the prolonged trade tensions risk disrupting supply chains and raising costs for consumers in both countries. The standoff highlights deeper disagreements over fair competition and industrial policies, leaving businesses and policymakers scrambling for solutions.
