Overview
- Canada’s retaliatory duties on roughly $20–$28 billion of U.S. imports took effect on Sept. 8, imposing rates of about 15% to 50% across more than 600 product categories.
- Prime Minister Mark Carney said Ottawa matched U.S. measures dollar for dollar, announced a C$7.5 billion support package for workers and firms, and pledged faster trade diversification away from U.S. markets.
- President Donald Trump directed the GSA and USTR to remove Canadian‑origin products from federal contracting schedules, opening a new procurement front that the White House values at about $50 billion a year.
- The levies hit sectors such as dairy, steel, aluminum, appliances, electronics and paper, threatening higher costs for producers and consumers and exposing exporters in key U.S. midterm states such as Michigan and Ohio.
- Analysts warn the escalation will disrupt integrated supply chains, prompt legal challenges to the rare Section 338 tariffs, and has prompted provincial steps—like Quebec’s 15% local‑content procurement rule—to shield local businesses.
