It was also the first Canadian election to use a lot of negative publicity; Anti-free trade advertising showed that negotiators were “moving away” from the free trade agreement, which turned out to be the Canada-U.S. border at the end of advertising. Although some opinion polls showed that there were slightly more Canadians against the deal than for him, the Mulroney Progressive Conservatives took advantage of being the only party in favour of the deal, while the Liberals and the NDP divided the vote on free trade. In addition, future Quebec premiers Jacques Parizeau and Bernard Landry supported the agreement, which was seen as a factor in supporting the PC party in Quebec.  Mulroney won a government majority and the agreement was introduced into law, even though a majority of voters had voted for parties opposed to free trade.   Other provisions have been established for the settlement of disputes between investors and participating countries. Such rules allowed, among other things, companies or individual investors to sue against compensation from any signatory country that violated the rules of the treaty. In 1994, the United States, Mexico and Canada, with the North American Free Trade Agreement (NAFTA), created the world`s largest free trade region, which generated economic growth and helped improve the living standards of the people of the three member countries. By strengthening trade and investment rules, this agreement has proven to be a solid foundation for building Canada`s prosperity and has provided a valuable example of the benefits of trade liberalization for the rest of the world.
The new Canada-U.S.-Mexico agreement will strengthen Canada`s strong economic ties with the United States and Mexico. During the negotiations, Canada retained the right to protect its cultural industries and sectors such as education and health. Some resources, such as water, should also be removed from the agreement. Canadians have failed to win free competition for U.S. government procurement. Canadian negotiators also emphasized the inclusion of a dispute resolution mechanism.  As the agreement indicates, the main objectives of the Canada-U.S. free trade agreement were the main objectives: the free trade agreement met with far less opposition in the United States.
Polls showed that up to 40% of Americans did not know that the agreement had been signed. The agreement law was submitted to Congress for “rapid” adoption by President Reagan on July 26, 1988, meaning that it could be accepted or rejected, but could not be amended. The United States-Canada Free-Trade Agreement Act of 1988 passed the House of Representatives by yes Nay: 366-40, passed in the House of Representatives on August 9, 1988, and voted in the Senate by yes Nay. 83-9, September 19, 1988.  The law was signed by the President on September 28, 1988 and became Public Law No. 100-449.  Although the agreement was maintained decades later, he was no longer at the helm of Canadian politics.  It was replaced in 1994 by the North American Free Trade Agreement (NAFTA). Jean Chrétien`s Liberals were elected in the 1993 election, in part with a promise to renegotiate important parts of NAFTA`s work and environment. In fact, an agreement was reached with Bill Clinton`s Democrats, who created separate secondary agreements to address both concerns.
Many critics of NAFTA saw the agreement as a radical experiment developed by influential multinationals who wanted to increase their profits at the expense of ordinary citizens of the countries concerned. Opposition groups argued that the horizontal rules imposed by nafta could undermine local governments by preventing them from enacting laws or regulations to protect the public interest. Critics also argued that the treaty would lead to a significant deterioration in environmental and health standards, promote privatization and deregulation of essential public services, and supplant family farmers in signed countries
