The president warned that any retaliatory tariff increases by Canada will be matched and added to the existing 35% levy.

WASHINGTON/OTTAWA, July 10 (Reuters) - U.S. President Donald Trump said on Thursday the United States would impose a 35% tariff on imports from Canada next month and planned to impose blanket tariffs of 15% or 20% on most other trading partners.

The president revived his discredited claims about fentanyl entering the U.S. from Canada to justify his latest proposed rate of 35 percent.
