President Donald Trump said he was ending all trade discussions with Canada in retaliation for the country’s digital services tax and threatened to impose a fresh tariff rate within the next week.

The president said he would cease negotiations and impose new tariffs because of Canada’s imminent, new digital services taxes.

The U.S. president pulled the plug on monthslong negotiations over what he called an “egregious” digital-services tax on U.S. tech companies, plunging relations with America’s second-largest trading partner back into turmoil.
