In 2015, the Congressional Research Service concluded that “the overall net effect of NAFTA on the U.S. economy appears to have been relatively modest, largely because trade with Canada and Mexico accounts for a small percentage of U.S. GDP. However, there have been adjustment costs for workers and businesses as the three countries have adapted to more open trade and investment between their economies. The report also estimates that NAFTA has added $80 billion to the U.S. economy since its inception, representing a 0.5% increase in U.S. GDP.  September 30, 2018, the day of the deadline for Canada-United States. The negotiations resulted in a provisional agreement between the two countries, preserving the trilateral pact when the Trump administration submits the deal to Congress.  The new name of the agreement was “United States-Mexico-Canada Agreement” (USMCA) and entered into force on July 1, 2020.   The North American Free Trade Agreement (NAFTA) was inspired by the success of the European Economic Community (1957-93) in eliminating tariffs to stimulate trade among its members. Proponents argued that establishing a free trade area in North America would bring prosperity through more trade and production, resulting in the creation of millions of well-paying jobs in all participating countries.
Before sending it to the U.S. Senate, Clinton added two side treaties, the North American Agreement on Labor Cooperation (NAALC) and the North American Agreement on Environmental Cooperation (NAAEC), to protect workers and the environment, as well as to allay the concerns of many members of the House of Representatives. The United States has required its partners to adhere to environmental practices and regulations similar to their own. [Citation needed] After lengthy deliberations and lively discussions, the U.S. House of Representatives passed the North American Free Trade Agreement Implementation Act on November 17, 1993, with measures 234-200. Among the supporters of the deal were 132 Republicans and 102 Democrats. The bill was passed by the Senate on 20 November 1993 by a vote of 61 to 38.  The Senate supporters were 34 Republicans and 27 Democrats. Republican Rep. David Dreier of California, a staunch supporter of NAFTA since the Reagan administration, has played a leading role in mobilizing support for the deal among Republicans in Congress and across the country.   Speaking to reporters aboard Air Force One on their way back from the G20 summit in Buenos Aires, Argentina, where the new deal was concluded, Trump said, “Just so you understand if I`m doing this — if, for some reason, we`re not able to make a deal because of Congress, then Congress will have a choice. ” approve the new agreement or return to pre-1994 trade rules when NAFTA entered into force. According to a 2017 report by the New York Council on Foreign Relations (CFR) think tank, bilateral trade in agricultural products tripled from 1994 to 2017 and is considered one of the largest economic impacts of NAFTA on U.S.-Canada trade with Canada, which is becoming the United States.
The largest importer in the agricultural sectors.  Canadian fears of losing manufacturing jobs to the U.S. did not materialize as manufacturing employment remained “stable.” However, with Labour Productivity in Canada at 72% of U.S. levels, hopes of closing the “productivity gap” between the two countries have also not materialized.  After U.S. President Donald Trump took office in January 2017, he attempted to replace NAFTA with a new agreement and began negotiations with Canada and Mexico. In September 2018, the United States, Mexico and Canada reached an agreement to replace NAFTA with the Agreement between the United States, Mexico and Canada (USMCA), and the three countries ratified it by March 2020. NAFTA remained in effect until the implementation of the USMCA.
 In April 2020, Canada and Mexico informed the United States that they were ready to implement the agreement.  The USMCA entered into force on July 1, 2020, replacing NAFTA. In 2017, Mexico and Canada were the second and third largest exporters after America, behind China in first place. However, current threats to withdraw the U.S. from NAFTA could have a significant impact on tariffs. Without NAFTA, which leaves tariffs between the three countries at around 0 percent, the tariffs would fall on tariffs set by the World Trade Organization, which average about 7.1 percent for Mexico, 3.5 percent for the United States and 4.2 percent for Canada, according to the New York Times. The North American Free Trade Agreement Implementation Act made some amendments to the U.S. Copyright Act, anticipating the Uruguay Round Agreements Act of 1994 by restoring copyright (in NAFTA countries) to certain films that had fallen into the public domain.
  In addition to expanding consumer choice over the past 20 years, NAFTA has increased trade between the three countries by about 3.5 times compared to 1994, according to a 2013 Associated Press report. When President Clinton first signed the treaty in 1993, he predicted huge economic benefits. Lone Pine Resources is incorporated in Delaware, but is headquartered in Calgary, and was the subject of an IPO on the New York Stock Exchange on May 25, 2011 of 15 million shares each for $13, raising $195 million.  NAFTA was a product of the early Bush and Clinton administrations — and 34 Republican senators voted for it — making it bipartisan, and President Clinton`s signing is sometimes called an important step in a shift to the right for Democrats. Clothing manufacturing is another industry that has been particularly affected by offshoring. Total employment in this sector has declined by nearly 85% since NAFTA was signed, but according to the Ministry of Commerce, Mexico was only the sixth largest source of textile imports of $4.1 billion in 2019. The country was still lagging behind other international manufacturers, including: According to a study published in the Journal of International Economics, NAFTA reduced pollution from the U.S. manufacturing sector: “On average, nearly two-thirds of the reductions in coarse particulate matter (PM10) and sulfur dioxide (SO2) emissions from U.S. manufacturing between 1994 and 1998 can be attributed to NAFTA trade liberalization.”  In 1994, the United States, Mexico and Canada created the world`s largest free trade region with the North American Free Trade Agreement (NAFTA), which generated economic growth and helped raise the standard of living of people in all three member states.
By strengthening trade and investment rules and procedures, this agreement has proven to be a solid foundation for building Canadian prosperity and has provided a valuable example of the benefits of trade liberalization for the rest of the world. The new agreement between Canada, the United States and Mexico will serve to strengthen Canada`s strong economic ties with the United States and Mexico. A 2001 review of the existing literature by the Journal of Economic Perspectives found that NAFTA was a net benefit to Mexico.  Until 2003, 80% of trade in Mexico was with the United States alone. The surplus in trade revenues, combined with the deficit with the rest of the world, has created a dependency on Mexico`s exports. .
