After talks between Canada and the U.S. broke down late Friday, the 50-percent US duty on certain Canadian-origin goods went into effect 12:01 a.m. Eastern Time on August 22nd, 2026.
Important: The 50-percent tariff will apply to the named goods regardless if those goods are qualified under CUSMA/USMCA (previous tariff actions included an exemption for CUSMA/USMCA but this tariff does not).
The listed goods, subject to the 50-percent tariff, may be found in the following (3) lists complete with tariff descriptions:
- List 1 (product list)
- List 2 (product list)
- List 3 (product list)
Prime Minister Mark Carney said, Saturday morning Canada will issue dollar-for-dollar retaliatory tariffs to take effect September 8, 2026. The list of US-origin goods to see additional tariffs upon import to Canada has not yet been published.
