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.”

The pauses—which allow a period of negotiations over drug trafficking and border security—provide a cool-down period after a tumultuous few days that put North America on the cusp of a trade war.
