The provisions of the Convention cover a wide range of agricultural products, homelessness, industrial products, working conditions and digital commerce. Among the most important aspects of the agreement are improving U.S. dairy farmers` access to the Canadian market, guidelines for a greater proportion of automobiles produced in the three countries and not imported from other countries, and maintaining the dispute settlement system, which is similar to that contained in NAFTA.  Trump made a relentless mockery of NAFTA as “the worst trade deal of all time” when he ran for president four years ago, arguing that it had put American workers at a competitive disadvantage. Other critics, including Democrats, have acknowledged that NAFTA is obsolete and needs to be reviewed. A new addition to the USMCA is the inclusion of Chapter 33, which covers macroeconomic policies and exchange rate issues. This is considered important because it could set a precedent for future trade agreements.  Chapter 33 sets out requirements for currency and macroeconomic transparency that, in the event of a breach, would be grounds for litigation under Chapter 20.  The United States, Canada and Mexico currently meet all of these transparency requirements in addition to substantive policy requirements that comply with the international Monetary Fund`s articles.  This agreement is the result of a renegotiation between member states of the North American Free Trade Agreement between 2017 and 2018, which formally approved the terms of the new agreement on 30 September 2018 and 1 October.
 The USMCA was proposed by U.S. President Donald Trump and signed on November 30, 2018 by Trump, Mexican President Enrique Pea Nieto and Canadian Prime Minister Justin Trudeau as a secondary event of the 2018 G20 summit in Buenos Aires. A revised version was signed on December 10, 2019 and ratified by the three countries, with final ratification (Canada) taking place on March 13, 2020 just before the Canadian Parliament adjourned due to the COVID-19 pandemic. Some senators have argued for the benefits of the new agreement for their own constituents, including Senate Majority Leader Mitch McConnell, R-Ky., who called it “a great victory for Kentucky and the 50 states.” The next step is for the three countries to indicate that they have met all the requirements of the agreement and to develop uniform rules that companies will use to comply with the agreement on a day-to-day basis. The agreed text of the agreement was signed by the heads of state and government of the three countries on November 30, 2018, as an incidental event at the 2018 G20 summit in Buenos Aires, Argentina.  The English, Spanish and French versions will also be binding and the agreement will take effect after ratification by the three states through the adoption of enabling laws.  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. For Trump, the revised deal is a significant victory as he fights impeachment proceedings in the Senate and is working to convince voters to put him on the job for another four years.
