Mr. Trudeau and Canadian Foreign Minister Chrystia Freeland announced that they would join the agreement if it was in Canada`s interest.  Freeland returned prematurely from his diplomatic trip to Europe and cancelled a planned visit to Ukraine to participate in the NAFTA negotiations in Washington at the end of August, D.C.  According to an August 31 Canadian press, published in the Ottawa Citizen, key supply management topics, Chapter 19, drugs, cultural exemption, sunset clause and de minimis thresholds.  Clinton signed it on December 8, 1993. The agreement came into force on 1 January 1994.   At the signing ceremony, Clinton paid tribute to four people for their efforts to reach the historic trade agreement: Vice President Al Gore, Council of Economic Advisers Chair Laura Tyson, National Economic Council Director Robert Rubin and Republican Congressman David Dreier.  Clinton also said, “NAFTA means jobs. U.S. jobs and well-paying American jobs. If I didn`t believe it, I wouldn`t support this agreement.  NAFTA replaced the old Canada-U.S. free trade agreement. On June 1, 2020, the USTR Office issued the uniform rules which are the last hurdle before the implementation of the agreement on July 1, 2020.
An April 2019 Analysis by the International Trade Commission on the likely effects of the USMCA estimated that the agreement would increase U.S. real GDP by 0.35 percent if the agreement were fully implemented (six years after ratification) and would increase total U.S. employment by 0.12% (176,000 jobs).   The analysis cited by another Congressional Research Service study showed that the agreement would not have a measurable effect on employment, wages or overall economic growth.  In the summer of 2019, Larry Kudlow, Trump`s chief economic adviser (the director of the National Economic Council at Trump White House), made unfounded statements about the likely economic impact of the agreement and overstated forecasts related to jobs and GDP growth.  The provisions of the Convention cover a wide range of agricultural products, from the homeless, industrial products, to working conditions and digital trade. 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.   The agreement between the United States of America and Mexico and Canada (USMCA) is a trade agreement between these parties.
The USMCA replaced the North American Free Trade Agreement (NAFTA). On April 3, 2020, Canada informed the United States and Mexico that it had completed its national process of ratifying the agreement.  Fox News reported on December 9, 2019 that negotiators from the three countries reached an agreement on enforcement, paving the way for a final agreement within 24 hours and ratification by all three parties before the end of the year.
