Canada braces for tariff shockwave as Washington's sweeping measures hit integrated supply chains
Canada's deep integration with the US economy puts it in an awkward position as Washington formally enacted the broadest tariff regime in post-war history. While Canada and Mexico have so far received partial carve-outs under CUSMA for certain goods, the broader tariff environment is disrupting automotive, steel, aluminium, and agricultural supply chains that cross the border daily. Prime Minister Trudeau convened an emergency cabinet session and spoke with President Trump, emphasising Canada's role as America's largest energy supplier and the mutual economic damage of escalation.
Canada's economic dependence on US trade — the US absorbs 75% of Canadian exports — means tariff escalation carries disproportionate risk. The auto sector is the most acute pressure point, given the deeply integrated manufacturing model across Ontario, Michigan, and Ohio. Advisers should be stress-testing client supply chains for tariff reclassification risk and preparing for prolonged negotiation timelines.
