Surtaxes of 15% to 50% hit about CA$27.6 billion of U.S. goods; Washington’s same-day moves were scope tweaks and procurement pressure, not a confirmed mirror package.

Canada’s United States Surtax Order (2026) took effect Tuesday, Sep. 8, applying 15%, 25%, or 50% surtaxes on listed U.S.-origin goods. Finance Canada puts coverage at about CA$27.6 billion of imports from the United States. CBSA Notice 26-23 frames the list as a response to U.S. Section 338 measures, with rates generally matching corresponding U.S. duties. Goods in transit are exempt.
Prime Minister Mark Carney said Tuesday that the pivot will come at a cost and that counter-tariffs are necessary to protect workers, companies, and communities.
The same day, White House proclamations modified existing Section 338 duties on alcohol and motor vehicles, effective Sep. 15. Reporting also cited a presidential directive for GSA to remove Canadian-origin products from GSA schedules unless reciprocity is restored. Those steps are not a confirmed mirror tariff package. A presidential social-media threat to stop Bombardier sales in the United States remains a claim, not an implemented ban.
