Since 8 September 2026 Canada has applied surtaxes of 15%, 25% and 50% to C$27.6 billion of US goods, including steel, aluminium, furniture, apparel, appliances, dairy and seafood. CBSA guidance (Customs Notice 26-23) says the surtax applies even to goods that would otherwise qualify for relief under the Postal Imports Remission Order or the Courier Imports Remission Order, so low-value parcels from US retailers are not carved out.
