National procedures for ratifying the agreement in the United States are governed by the legislation of the Trade Promotion Authority, which is also known as the fast-track authority. The USMCA establishes the highest level of a U.S. trade agreement for strong and effective protection and enforcement of intellectual property rights. This is a significant enhancement of NAFTA. Nevertheless, in December 2019, following negotiations on the revision of the USMCA text signed in November 2018, substantial changes were made to Chapter 20 of intellectual property. The negotiations focused “primarily on car exports, tariffs on steel and aluminum, as well as the milk, egg and poultry markets.” A provision “prevents any party from enacting laws that restrict the cross-border flow of data.”  Compared to NAFTA, the USMCA increases environmental and labour standards and encourages domestic production of cars and trucks.  The agreement also provides up-to-date intellectual property protection, gives the U.S. more access to the Canadian milk market, imposes a quota for Canadian and Mexican auto production, and increases the customs limit for Canadians who purchase U.S. products online from $20 to $150.  The full list of differences between USMCA and ALEFTA is listed on the Website of the United States Trade Representative (USTR).  The agreement between the United States of America, the United States of Mexico and Canada, commonly known as the United States-Mexico-Canada Agreement (USMCA), is a free trade agreement between Canada, Mexico and the United States, which succeeds the North American Free Trade Agreement (NAFTA).    The agreement has been referred to as NAFTA 2.0 or “New ALEFTA, since many nafta provisions have been introduced and its amendments have been found to be largely incremental.
On 1 July 2020, the USMCA came into force in all Member States. Canada ratified the agreement in March and the USMCA came into force on July 1, 2020. Although NAFTA is officially dead, governments and businesses are still adapting to the new rules, especially the new labour rules. Coronavirus can also complicate implementation as manufacturers adapt to new guidelines in the midst of a global economic crisis. On December 10, 2019, the three countries reached a revised USMCA agreement. On January 29, 2020, Deputy Prime Minister and Minister of Intergovernmental Affairs Chrystia Freeland introduced the USMCA C-4 Transposition Act in the House of Commons and passed the first reading without a registered vote. On February 6, the bill passed second reading in the House of Commons by 275 votes to 28, with the Bloc Québécois voting against and all other parties voting in its favour, and it was referred to the Standing Committee on International Trade.    On 27 February 2020, the committee voted to send the bill to Parliament for third reading, without amendments. On December 9, 2019, Fox News reported that negotiators from the three countries reached an agreement on implementation, paving the way for a final agreement within 24 hours and ratification by all three parties before the end of the year. Mexico has agreed to impose a minimum wage of $16 per hour for Mexican auto workers by a “neutral” third party. Mexico, which imports all of its aluminum, also objected to the provisions relating to the U.S. steel and aluminum content of automotive components.
 The FDA was an important member of the U.S. team that negotiated the U.S.-Mexico-Canada (USMCA) agreement, which came into effect on July 1 of this year. From the FDA`s perspective, the agreement adapts regulatory standards to public administration practices, improves the quality of products available to U.S. consumers and a level playing field for U.S. companies.
