John Weekes writes an op-ed column in the Globe and Mail on ?why Canada's relationship with Mexico matters so much in light of Donald Trump's pledge to renegotiate or withdraw from NAFTA. John says that as Canada prepares for a possible renegotiation of NAFTA, we should use the current situation as an opportunity to strengthen our long-term strategic partnership with Mexico. The country is one of the world’s pre-eminent emerging economies and has the 15th-largest GDP in the world - Canada ranks 10th. ?John is the former Canadian chief negotiator for NAFTA.  John also explains why it would be a loss for Canada if the U.S. backed out of NAFTA and we had to fall back on the Canada-U.S. FTA.
