Overall, Canada has become more dependent on trade with the United States and has based its southern neighbour on 75 per cent of its exports. Other high-income countries tend to be much more diverse and rarely rely more than 20% on a single partner. U.S. presidents have long,s warm relationships with Canadian prime ministers, but Mr. Trump has not hesitated to use that dependency as leverage. As part of the USMCA talks, he threatened to impose new tariffs on Canadian auto parts if Ottawa did not accept trade concessions. The North American Free Trade Agreement (NAFTA); in Spanish: Tratado de Libre Comercio de América del Norte, TLCAN; In French: North American Free Trade Agreement, ALNA) was an agreement signed by Canada, Mexico and the United States, creating a trilateral trade bloc in North America. The agreement came into force on January 1, 1994 and replaced the 1988 Canada-U.S. Free Trade Agreement.  The NAFTA trading bloc was one of the largest trading blocs in the world, after the proceeds of the home. According to the Department of Homeland Security Immigration Statistics, 73,880 foreign skilled workers (64,633 Canadians and 9,247 Mexicans) were admitted to the United States for temporary employment under NAFTA (i.e.
NT status) in fiscal year 2006 (October 2005-September 2006). In addition, 17,321 family members (13,136 Canadians, 2,904 Mexicans and a number of third-country nationals married to Canadians and Mexicans) entered the United States.  Given that DHS counts the number of new I-94 arrivals at the border and that TN-1 admission is valid for three years, the number of non-immigrants in NT status in the United States at the end of the fiscal year is approximately the number of admissions during the year. (A discrepancy may be caused by some NT participants leaving the country or changing status before their three-year admission period expires, while other immigrants admitted earlier may change their status to NT or TD or extend previously granted TN status). Nevertheless, the “Most Favored Nation” (MFN) clause played an important role in nafta. Under NAFTA, all co-signed countries are granted MFN status, which means that they have to treat all parties on a single level in terms of trade. Thanks to the MFN, countries are not allowed to favour investors from non-NAFTA countries or to show greater favours towards foreign investors. In fact, they all have to be treated the same in the agreement. Sixth, the agreement provided business travellers with easy access to all three countries. The overall effect of the agricultural agreement between Mexico and the United States is controversial. Mexico has not invested in the infrastructure needed for competition, such as efficient railways and highways. This has led to more difficult living conditions for the country`s poor.
Mexico`s agricultural exports increased by 9.4% per year between 1994 and 2001, while imports increased by only 6.9% per year over the same period.  Although the long-term benefits of NAFTA are discussed in depth, the agreement has been successful since its implementation in the 1990s.
