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.

President Trump's tariff agenda is nearing a moment of truth with an Aug. 1 deadline just a few hours away and set to establish a new baseline rate of at least 15% on most of the world. Many final moves have come in a flurry (from a deal with South Korea to a delay with Mexico),

US President Donald Trump announced a slew of new tariffs on at least 85 countries, including the ones he has made a trade deal with, hours before the August 1 deadline.
