Despite winning a month-long reprieve from potentially devastating U.S. tariffs, there is a deep sense of anxiety hanging over some of the most senior Canadian government officials who manage the relationship with President Donald Trump.

Trump on Saturday had directed that 25% tariffs on most imports from the two American partners — and 10% on Canadian energy products — go into effect at midnight Tuesday.

President Donald Trump agreed to pause the implementation of planned tariffs on imports from Canada for at least 30 days, Canadian Prime Minister Justin Trudeau said. The pause was announced hours after Trump and Mexico’s president said Trump would pause for one month planned tariffs on imports from Mexico.
