After U.S. President Donald Trump took office in January 2017, he attempted to replace NAFTA with a new agreement and began negotiations with Canada and Mexico. In September 2018, the United States, Mexico and Canada reached an agreement to replace NAFTA with the United States,Mexico-Canada Agreement (USMCA) and all three countries had ratified it until March 2020. NAFTA remained in effect until the IMPLEMENTATION OF THE USMCA. [13] In April 2020, Canada and Mexico informed the United States that they were ready to implement the agreement. [14] The USMCA came into force on July 1, 2020 and replaced NAFTA. While the heads of state and government of the three countries have signed the agreement, it will only be able to enter into force when the governments of the three countries adopt it. However, the United States has yet to pass the USMCA as law. Critics have also argued that the treaty would lead to a significant deterioration in environmental and health standards, promote the privatization and deregulation of important public services, and supplant family farmers in signatory countries. . . .
