“The tariffs are going forward on time, on schedule,” Trump said. Trump’s executive order to implement 25 per cent tariffs on all Canadian imports, with a lower 10 per cent levy on energy, was delayed until March 4 after Canada agreed to introduce new security measures at the border.

Foreign Affairs Minister Mélanie Joly responded in part to the U.S. president's claims by saying the U.S. is a "net exporter" of illegal fentanyl, guns and migrants to Canada.

President Donald Trump, asked on Monday whether tariffs would be placed on Canadian and Mexican goods when the deadline for a pause on such action arrives next week, reiterated his view that the United States had been mistreated by its neighbors and allies.
