Canada would impose 25% tariffs on C$155 billion ($106.5 billion) of U.S. goods in response to U.S.
tariffs. C$30 billion would take effect from Tuesday and C$125 billion in 21 days, Trudeau told a news conference.
Trump earlier signed an executive order imposing 25% tariffs on all goods from Canada and Mexico starting on Tuesday except Canadian energy products, which will be subject to a 10% duty.
