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.

Trump said it would be “very hard” to reach a deal with Canada after the country said it plans to recognize a Palestinian state in September.

Canada's recognition of Palestinian statehood will make it tougher for the U.S. to agree to a trade deal with its northern neighbor, President Donald Trump warned overnight, with just a day to go until the deadline the White House has set for tariffs to snap higher.
