7. Section 103 (c) (5) (B) of the USMCA Implementation Act authorizes the President to announce changes to the provisions enacted under the control of Section 103 (c) (5) (A), subject to the consultation and reflection procedures of Section 104, as long as it is necessary for the implementation of an agreement under Article 6.4 of the USMCA. The North American Free Trade Agreement (NAFTA), signed by Prime Minister Brian Mulroney, Mexican President Carlos Salinas and U.S. President George H.W. Bush, came into force on January 1, 1994. NAFTA has created economic growth and a rising standard of living for the people of the three member countries. By strengthening trade and investment rules and procedures across the continent, Nafta has proven to be a solid foundation for building Canada`s prosperity. NAFTA replaced Canada-U.S. Free Trade Agreement (CUFTA). Negotiations on CUFTA began in 1986 and the agreement entered into force on 1 January 1989. The two nations agreed on a landmark agreement that put Canada and the United States at the forefront of trade liberalization.

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.   It is impossible to isolate the effects of NAFTA on the broader economy. For example, it is difficult to say with certainty what percentage of the current U.S. trade deficit, which reached a record $65,677 million at the end of 2005, is directly attributable to NAFTA. It is also difficult to say what percentage of the 3.3 million manufacturing jobs that were lost in the United States between 1998 and 2004 is the result of NAFTA and what percentage would have been created without this trade agreement. It cannot even be said with certainty that the intensification of trade between NAFTA countries is exclusively the result of the trade agreement. Those who support the agreement generally claim NAFTA loans for enhanced trade activity and reject the idea that the agreement has resulted in job losses or a growing trade deficit with Canada and Mexico ($8,039 million and $4,263 million respectively in December 2005).
