Trump slaps 35 percent tariff on Canada starting August 1

US president also eyes blanket tariffs of 15 to 20 percent on other trading partners as his trade war widens.

President Donald Trump has announced that the United States would impose 35 percent tariff on imports from Canada next month while eyeing blanket tariffs of 15 or 20 percent on most other trading partners as he broadens his trade war.

In a letter released on his social media platform on Thursday, Trump told Canadian Prime Minister Mark Carney the new rate would go into effect on August 1 and would go up if Canada retaliated.
