After Canada failed to strike a trade deal with Washington, the president raised tariffs on some Canadian exports this week.

U.S. President Donald Trump has raised the tariff rate on U.S. imports from Canada to 35% from 25%, effective Friday.

Trump has justified tariffs on goods from Canada, the top U.S. export market, by accusing it of failing to stop the cross-border flow of fentanyl, even though U.S. government data shows Canada accounts for only 1% of the fentanyl that enters the United States.
