Deadline passes for Trump's tariffs with no relent

Canadians are waking up to a new and uncertain reality after U.S. President Donald Trump's deadline for economy-wide tariffs passed with no relent overnight, triggering a continental trade war.

The president's executive order hitting Canada and Mexico with 25 per cent across-the-board tariffs, with a lower 10 per cent levy on Canadian energy, took effect at 12:01 a.m. ET.

In a statement Monday night, Prime Minister Justin Trudeau said Trump's tariffs are "unjustified" and Canada will retaliate with counter-tariffs and other measures.

Canada's response is to start with tariffs on $30 billion worth of goods immediately and tariffs on the remaining $125 billion worth of American products 21 days later.

Trudeau is set to hold a press conference in Ottawa Tuesday morning with Finance Minister Dominic LeBlanc, Foreign Affairs Minister Mélanie Joly and Public Safety Minister David McGuinty.
