Canada has given Trump a tight slap in the face.

The "poison" clause in the new NAFTA amongst the 3 countries (US, Mexico & Canada) doesn't allow any party to sign a FTA with a non-market economy defined under WTO and China has a non-market economy status.

Any party who signs a FTA with a non-market economy will render the new NAFTA void in 6 months time.  Look like Canada is going to void the new NAFTA and piss Trump off.
