President Donald Trump announced a new set of duties on Canadian goods that were not covered by existing sectoral tariffs.

The president said the blanket 35% would be on top of tariffs on certain sectors. That’s higher than the previous 25% rate.

Letters went to 23 other American trading partners this week, including Canada, Japan and Brazil, setting blanket tariff rates ranging from 20 percent

The letter reiterated Trump’s complaints about dairy quotas, fentanyl and the U.S. trade deficit, which is mostly fueled by American refineries’ thirst for Canadian oil. His social media post caused the Canadian dollar to immediately tumble, indicating the market wasn’t expecting this escalation.

President Donald Trump published a letter to Prime Minister Mark Carney on Thursday, accusing Canada of having "financially retaliated" against the U.S.

Canada is one of the United States' top trading partners, with more than $410 billion of goods crossing into the country last year.

Tariff negotiations between the two top trading partners are on a different track from those the U.S. is pursuing with other nations. But Canada may not get a better outcome.
