The Trump administration has escalated trade tensions with Canada by imposing sweeping tariffs on key exports. Initially targeting steel and aluminum with a 25% tariff, the U.S. has expanded its approach to include Canadian lumber, dairy and other industries. In response, Canada has announced retaliatory tariffs while unveiling a $6-billion aid program to support businesses affected by the trade dispute.
