US trade war - a new missive by US Donald Trump threatening an unexpected 35% tariff on Canadian goods starting next month. It came as the two countries engage in intense trade talks meant to produce a new deal in the coming days and what the latest tariff threat means for these negotiations is unclear.

A day after President Trump announced a new 35 percent tariff on Canadian goods beginning next month, Prime Minister Mark Carney said Canada had made “vital progress” towards stopping fentanyl.

Canadian Prime Minister Mark Carney's statement came after US President Donald Trump said the new tariff rate would go into effect on August 1 and would go up if Canada retaliated.

U.S. President Donald Trump is threatening to hit Canadian imports with 35 per cent tariffs on Aug. 1, reviving the trade war between the neighbouring countries.

Prime Minister Mark Carney says U.S. President Donald Trump has multiple objectives in his trade talks with various countries, including how it will impact the U.S. budget.

Doubling down on his trade wars, President Trump is threatening to raise taxes on many goods from Canada and punish Brazil for prosecuting his friend.

The announcement came Friday after U.S. President Donald Trump's latest escalation of his tariff threat against Canada.
