📝 Executive Summary
Canada's merchandise trade surplus widened sharply in May 2026, reaching its largest level since the U.S. imposed tariffs on steel and aluminum in 2018, driven by surging crude oil exports. Energy shipments rose by double digits in value terms as global oil benchmarks stayed above $80 a barrel. The surplus underscores Canada's reliance on petroleum exports and is likely to support the Canadian dollar, reinforcing the loonie's correlation with crude prices.
