Canada Tariffs Research Brief

Tensions escalate as trade talks falter. The United States imposed 50 per cent Section 338 tariffs on roughly $20 billion of Canadian goods in August, about 5 per cent of the nation’s exports. The measures add to existing sectoral tariffs on autos, metals, and lumber, and the affected products do not qualify for a USMCAcompliant exemption. Ottawa has responded with a similar-sized package of counter-tariffs, risking further escalation. While the directly affected industries are a relatively small part of Canada’s economy, weaker exports could materially slow near-term growth. More importantly, renewed uncertainty may further delay USMCA negotiations and business investment, creating additional challenges for an economy still navigating the effects of earlier trade disruptions.
