New levies, apart from the 25% on auto parts and 50% on steel and aluminum, will come into effect on 1 August
Donald Trump has said the US will impose a 35% tariff on imports from Canada next month and threatened to impose blanket tariffs of 15% or 20% on most other trade partners.
In a letter released on his social media platform, Trump told Mark Carney, the Canadian prime minister, the new rate would go into effect on 1 August and would increase if Canada retaliated.
