Canada will impose retaliatory tariffs on US goods in response to President Donald Trump’s apparent election decision to restore a 10 percent tariff on Canadian aluminum imports. Trailing in polls four months before the US general election, Trump made the announcement during a campaign speech at a Whirlpool factory in Ohio. He framed the tariff not as protectionism but as a concern for national security. Prime Minister Justin Trudeau and Deputy Prime Minister Chrystia Freeland announced the measures within hours of Trump’s decision. Freeland, in a statement, said Canada “intends to swiftly impose dollar-for-dollar countermeasures” in response.
