Canada has given the US and Mexico official notice that it wants the free trade deal between the three countries to be renewed. In a letter to his American and Mexican counterparts, Canada-US Trade Minister Dominic LeBlanc said the country is seeking renewal of CUSMA when it comes up for review on July 1. LeBlanc is in Washington Tuesday for a meeting with U.S. Trade Representative Jamieson Greer. All the signals from the White House over the past year and a half indicate that the Trump administration does not want a straightforward renewal of CUSMA and instead wants significant changes to its terms. …LeBlanc calls CUSMA “highly beneficial to each of our countries and to the integrated North American economy,” but goes on to acknowledge that the other countries may want to propose “improvements.” …Whatever happens on July 1, CUSMA is slated to remain in effect until 2036.
