Trump has long proposed raising tariffs—or taxes on imported goods that the businesses importing them pay the U.S. government—before the election, and said in November he’ll impose a 25% tariff rate on all imports from Mexico and Canada on the first day of his presidency and will impose an additional 10% tariff rate on all imports from China on top of other tariffs.

President Donald Trump said he plans to speak Monday with Canadian Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum before steep new tariffs on U.S. allies and trading partners are scheduled to take effect early Tuesday.
