On October 30, 2007, U.S. citizens Marvin and Elaine Gottlieb filed a letter of intent to file an arbitration application under NAFTA alleging that thousands of U.S. investors lost a total of $5 billion to the Conservative government`s decision last year to change the tax rate on income trusts in the energy sector. On 29 April 2009, it was found that this change in tax legislation did not involve expropriation.  The adoption of NAFTA led to the elimination or elimination of barriers to trade and investment between the United States, Canada and Mexico. The impact of the agreement on issues such as employment, the environment and economic growth has been the subject of political debate. Most economic analyses have shown that NAFTA is beneficial to North American economies and the average citizen, but harms a small minority of workers in industries exposed to commercial competition.   Economists believed that leaving NAFTA or renegotiating NAFTA in a way that would have restored trade barriers would have impacted the U.S. economy and expensive jobs.    However, Mexico would have been much more affected by job losses and declining economic growth, both in the short and long term.  According to a 2018 report by Gordon Laxter by the Council of Canadians, Article 605 of NAFTA, the disproportionate energy rule, ensures that Americans had “virtually unlimited initial access to most Canadian oil and gas products” and that Canada could not reduce its oil exports, natural gas and electricity (74% of its oil and 52% of its natural gas) to the United States.
even though Canada was close. These provisions, which seemed logical when NAFTA was signed in 1993, are no longer adequate. :4 The Council of Canadians promoted environmental protection and opposed NAFTA`s role in promoting oil sands development and hydraulic fracturing.  The objective of NAFTA was to reduce barriers to trade and investment between the United States, Canada and Mexico. The introduction of NAFTA on 1. January 1994 resulted in the immediate elimination of tariffs on more than half of Mexico`s exports to the United States and more than a third of U.S. exports to Mexico. Within 10 years of implementing the agreement, all tariffs between the U.S. and Mexico are expected to be abolished, with the exception of some U.S. agricultural exports to Mexico, which are expected to expire within 15 years.  Most of the trade between the United States and Canada was already duty-free.
NAFTA also aimed to eliminate non-tariff barriers to trade and protect intellectual property rights in traded goods. Proponents of NAFTA in the United States have stressed that the pact is a free trade agreement, not an agreement of the economic community.  The free movement of goods, services and capital established therein did not extend to labour […].
