NAFTA has also used a new era of free trade agreements, which have multiplied as World Trade Organization (WTO) global trade negotiations, and has played a pioneering role in integrating labour and environmental provisions, which have become increasingly broad in subsequent free trade agreements [PDF]. The USMCA has put in place stricter enforcement mechanisms than the original agreement, which has led the AFL-CIO, the largest collection of U.S. unions, to support the pact – a rare endorsement from a group that has strongly criticized NAFTA. The USMCA requires automakers to produce at least 75% of the vehicle`s components in Canada, Mexico or the United States. Previously, it was 62.5%. At least 40% of the value of a car and 45% of a light truck must be manufactured by workers who earn an average of $16 per hour. Cars that do not meet these requirements are subject to sales rates. This agreement protects Mexico and Canada from future U.S. car taxes.

Overall, Canada has become more dependent on trade with the United States and relied on its southern neighbour for 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) was a three-country agreement negotiated by the governments of Canada, Mexico and the United States, which came into force in January 1994. NAFTA eliminated most tariffs on goods traded between the three countries, with a focus on trade liberalization in agriculture, textiles and automobiles. The agreement also aimed to protect intellectual property, establish dispute resolution mechanisms and implement labour and environmental protection measures through ancillary agreements.

To facilitate the strengthening of cross-border trade, the United States has reached an agreement with Mexico and Canada to increase the value of de minimis delivery. For the first time in decades, Canada will increase its de minimis level from $20 ($15.38) to $40 ($30.77) for taxes. Canada will also offer duty-free shipments of up to 150 $US ($115.38). Mexico will continue to provide $50 de minimis exemptions and will also offer duty-free shipments of up to $117.
