U.S. President Donald Trump on Thursday temporarily waived tariffs on some, but not all, products from Canada and Mexico two days after launching a continental trade war, specifically those that fall under the North American free trade agreement.

Trump signed a new executive order giving some exemptions to Canada after originally saying Thursday that only Mexico would get a partial reprieve on sweeping tariffs until April 2.

The delay in an exemption for Canada came after Trump levelled new attacks against prime minister justin Trudeau following a heated exchange Wednesday.

Canada will delay its second round of retaliatory tariffs until April 2 as a result of Trump’s temporary reprieve, Finance Minister Dominic LeBlanc announced later on Thursday.
