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.

Trump pledged in his inaugural address that tariffs would be coming in a speech in which he promised a golden era for America. He later said Canada and Mexico could be hit with the tariffs as soon as Feb. 1, though he signed an executive order requesting a report coordinated by the Secretary of Commerce by April. 1.

Canada’s effort to push back against possible US tariffs is being undermined by Alberta Premier Danielle Smith’s pledge to fight federal plans to cut or tax crude exports to the US, Canada’s natural resources minister said.
