US President Donald Trump has announced that all imports from Canada will have a 35% tariff as of August 1. He sent a letter to the country’s president, Mark Carney, informing him of the new rate, which has also been posted on his Truth Social account.

Trump threatened to escalate tariffs beyond 35% if Canada opts to retaliate with tariffs on U.S. goods. Canadian goods are also subject to sector-specific tariffs, such as 50% levies on steel and aluminum as well as 25% tariffs on non-USMCA compliant autos and auto parts.

Prices of copper in the US have surged since January, when President Donald Trump threatened to impose a tariff on imports of the metal that’s a vital component in power networks, plumbing and industrial machinery.
