Conservative Party of Canada Leader Pierre Poilievre pushed back against President-elect Donald Trump’s intent to impose tariffs on Canada, calling on his country to “stand strong” against the United States.

Trudeau blasted Smith, reminding her that the federal government bought the Trans Mountain pipeline, which now has a C$34.5 billion price tag, giving Alberta its only route to export oil from Canada’s Pacific coast.

The government is preparing for the possibility that the incoming U.S. administration will impose high tariffs on Canadian goods, setting the close allies up for a showdown.
