Canadians upset about the tone of relations with the U.S. can express themselves with their wallets, Prime Minister Justin Trudeau said.

Asked Wednesday about potential boycotts of American goods or trips south of the border after the Trump administration imposed tariffs on steel and aluminum, the Canadian leader said it’s up to individuals to decide.

“I’m always one to encourage Canadians to discover our extraordinary country, to take vacations here at home, to continue to buy Canadian, and if Canadians are looking for extra reasons to do so, then so be it,” Trudeau said at a press conference marking the start of Parliament’s summer recess. “I think it’s important for Canadians to make their own choices about how they want to spend their money.”

A boycott-the-U.S. campaign has been simmering since Donald Trump and his advisers lashed out at Trudeau after the Group of Seven leaders summit earlier this month. The prime minister told reporters he hasn’t spoken to the U.S. president since then.
