This threat needs all hands on deck, and a full spectrum response from Canada.  Brian Mulroney is an obvious asset with NAFTA and it sounds like Brad Wall is another.  Good on Trudeau for realizing it and asking for their support.

To be fair, there is a populist protectionism breuing on both ends of the political spectrum.  Had Burney Saunders won the US election, we could have been having the same discussions around trade.
