After a three-week respite, on Feb. 24 President Donald Trump renewed his threat of sweeping tariffs on goods from Canada and Mexico.

Crude and natural gas from Canada face a 10% tariff, all other goods coming into the U.S. from its north and south neighbors will face a 25% fine.

Trump made the comments during a joint press conference with French President Emmanuel Macron at the White House.

“The tariffs are going forward on time, on schedule,” Trump said at the press conference.

Upon taking office, Trump threatened to implement the tariffs by the end of January. Then, after both countries moved to increase border security, the president delayed implementation until the end of February.

Trump said the tariffs are needed to decrease the traffic of illegal immigration and illicit drugs such as fentanyl. The president has also said the U.S. is already getting an unfair deal under the current system of tariffs over the North American countries.
