On November 30, 2018, Canada, the United States and Mexico signed the new Canada-United States-Mexico Agreement (CUSMA), on the margins of the G20 Leaders’ Summit in Buenos Aires. Parties are now undertaking their domestic process towards ratification and implementation of the CUSMA. The CUSMA outcomes preserve key elements of this trading relationship and incorporate new and updated provisions that seek to address 21st-century trade issues and promote opportunities for the nearly half a billion people who call North America home.
