US puts 50% tariffs on some Canadian goods as talks collapse; Ottawa vows matching response

Summary

Washington moved ahead with 50% tariffs on a range of Canadian goods after trade talks broke down on 22 August, and Ottawa pledged a dollar-for-dollar response. The escalation follows the expiry of 10% Section 122 global tariffs on 23 July and their replacement the next day by 10-12.5% Section 301 forced-labour duties covering 60 economies and roughly 99% of US imports. Importers should model fresh duty exposure and expect another pull-forward of shipments.
