📝 Executive Summary
The US imposed a 25% tariff on Canadian steel, prompting Ottawa to cancel the ribbon-cutting for the new Gordie Howe International Bridge. The diplomatic snub threatens US-Canada trade relations and weighed on the Canadian dollar, which fell 0.3% against the greenback. Analysts see the tariff escalation as a setback for the USMCA and a negative for cross-border manufacturing supply chains.
