The new Agreement is known in Canada as the Canada-United States-Mexico Agreement (CUSMA, or the Agreement).Footnote1 Subsequently, on December 10, 2019, the parties signed a Protocol of Amendment to modify certain elements of the new Agreement in the areas of state-tostate dispute settlement, labour, environment, intellectual property and rules of origin. The final CUSMA outcome preserves key elements of NAFTA, modernizes disciplines to address modern trade challenges, reduces red tape at the border, and provides enhanced predictability and stability for workers and businesses across the integrated North American market. Overall, the modernization of NAFTA marks an important milestone in Canada’s economic relationship with the United States and Mexico.
