The United States and Canada have entered into uncharted territory.

The longtime allies and economic partners, who have enjoyed free trade for decades, are now in an escalating trade war with no clear off ramp.

And for Prime Minister Mark Carney, the late night decision to suspend talks with President Donald Trump and to retaliate instead of agreeing to a deal that seemed in reach will be a significant political test.

He is one of the first world leaders to walk away from the negotiating table with the White House - and the outcome will be closely watched.
