Canadian Prime Minister Justin Trudeau said Monday in a social media post that the United States had agreed to pause threatened tariffs for “at least 30 days.” The announcement followed two phone calls with President Donald Trump on Monday and came after the United States and Mexico reached a similar agreement.

Feb. 3, 1:57 p.m. EST Trump announced the tariffs against Canada will be paused for 30 days, saying the longtime U.S. ally will implement a $1.3 billion border reinforcement plan that will bolster the U.S.-Canada border with “new choppers, technology and personnel... and increased resources to stop the flow of fentanyl.”

Tariffs were the part of Trump’s economic plan investors disliked the most.
