Trump threatens to impose an additional 10% tariff on Canadian goods, with seafood still under the protection of the USMCA.

This advertisement referenced former U.S. President Reagan's stance on free and fair trade, but Trump believes that Canada released false information intended to influence the U.S. Supreme Court's decision on the tariff issue.

"Given Canada's serious distortion of facts and hostile actions, I have decided to impose an additional 10% tariff on top of the current tariff payment amount to Canada," Trump said on the Truth Social platform.

On the 23rd, Trump announced the termination of all trade negotiations with Canada. On July 31, Trump signed an executive order raising tariffs on some Canadian goods to 35%, but excluding products covered by the USMCA, which temporarily spared seafood. (The review deadline for the USMCA is July 1, 2026.)

As of now, anti-tariff advertising campaigns in Ontario have been suspended.

Canada is the largest seafood trade partner of the United States, with exports to the U.S. amounting to nearly $40 billion last year, and imports of over $1 billion worth of seafood from the U.S. High-value traded items include lobster, snow crab, farmed Atlantic salmon, and various white fish species and shellfish.
