Canadian Prime Minister Justin Trudeau said the new version of NAFTA will lift the risk of serious economic uncertainty that lingers throughout a trade renegotiation process. He said this new deal was all the more reason they need to keep working to remove the trade barriers.    US President Donald Trump called new trade pact as model agreement that changes the trade landscape forever. He believed this deal will create major changes for automakers, new labor, and intellectual property protections. Mexican President Pena Nieto called the deal important in shoring up the view of an integrated North America with the firm belief that together they are stronger and more competitive.
