The United States-Mexico-Canada Agreement (USMCA): A Successor to NAFTA

Writer's picture: Tom McAndrewTom McAndrew

The United States-Mexico-Canada Agreement (USMCA) is a free trade agreement that replaced the North American Free Trade Agreement (NAFTA) on 1st July 2020. It was renegotiated largely due to criticisms of NAFTA, which had governed trade between the three North American countries since 1994. While NAFTA had eliminated most tariffs and encouraged economic integration, it also faced substantial criticism, particularly regarding its impact on employment, environmental standards, and trade imbalances. The USMCA was introduced with the aim of addressing these issues while modernising trade relations.


Key Features of the USMCA


The USMCA retains many aspects of NAFTA but introduces several important changes. The most significant amendments include:


  1. Automobile Industry Reforms


    - Under the new agreement, 75% of a vehicle’s parts must originate in North America (up from 62.5% under NAFTA) to qualify for zero tariffs.

    - A provision requires that 40-45% of vehicle content must be made by workers earning at least $16 per hour, aimed at reducing outsourcing to Mexico where wages are lower.


  2. Labour and Wage Standards


    - Mexico agreed to stronger labour laws, including allowing independent trade unions and improving working conditions. This was an attempt to reduce unfair wage disparities that had made Mexican labour much cheaper than in the U.S. and Canada.


  3. Digital Trade and Intellectual Property Protection


    - Since NAFTA was signed before the digital economy’s boom, USMCA incorporates new provisions for e-commerce, data protection, and intellectual property rights, ensuring a more modern trade framework.


  4. Agricultural Market Access


    - The USMCA grants U.S. dairy farmers greater access to the Canadian market, which had previously maintained high tariffs and quotas to protect its domestic industry.

    - Canada also agreed to allow more imports of U.S. poultry and eggs.


  5. Environmental Provisions


    - The agreement includes stronger environmental commitments compared to NAFTA, including measures to prevent overfishing and pollution, as well as commitments to enforce existing environmental regulations.


Positive Achievements of the USMCA


The USMCA has been praised for addressing some of NAFTA’s major shortcomings and adapting the agreement to a changing global economy.


  1. Boosting Wages and Protecting Workers


    - The wage provisions in the automotive sector aim to prevent companies from relocating to Mexico purely for cost-cutting. Higher wages should theoretically lead to improved living standards for Mexican workers while ensuring fairer competition for U.S. and Canadian employees.


  2. Strengthening the North American Supply Chain


    - The increase in North American content requirements for vehicles encourages manufacturers to source more components from within the region. This strengthens supply chains and reduces dependency on foreign suppliers, particularly from Asia.


  3. Modernising Trade for the Digital Economy


    - By including rules on data flows, intellectual property, and online trade, the USMCA recognises the growing importance of digital commerce, something NAFTA failed to address. This is especially beneficial for industries such as technology, software, and digital services.


  4. Enhanced Market Access for Farmers


    - U.S. dairy farmers benefit significantly from greater access to the Canadian market, which had previously been highly protectionist. This change ensures fairer competition and expands opportunities for agricultural exports.


  5. Stronger Environmental Commitments


    - While not as extensive as some environmental groups would like, the inclusion of enforceable environmental standards is an improvement over NAFTA. These provisions may help mitigate the environmental impact of industrial and agricultural production across the region.


Criticisms of the USMCA


Despite its advantages, the USMCA has not been without controversy. Critics argue that certain aspects of the deal may have unintended negative consequences.


  1. Potential for Higher Production Costs and Consumer Prices


    - The requirement that a higher percentage of vehicle components be sourced from North America, combined with higher wage rules, increases production costs. These costs may be passed on to consumers in the form of higher prices for cars and trucks.


  2. Limited Environmental Protections


    - Although the USMCA includes environmental provisions, critics argue they are not strong enough to address major concerns such as carbon emissions, deforestation, and pollution. Some argue that the deal lacks the enforcement mechanisms necessary to hold businesses accountable for environmental violations.


  3. Ongoing Trade Tensions and Uncertainty


    - While the USMCA was designed to stabilise trade relations, political disagreements persist. For example, the U.S. has periodically reimposed tariffs on Canadian aluminium and steel, demonstrating the fragility of trade relations despite the agreement.


  4. Failure to Fully Address Outsourcing Concerns


    - While some provisions aim to curb job outsourcing to Mexico, companies may still find ways to exploit lower wages and weaker labour laws. Some critics argue that the changes are not substantial enough to reverse decades of job losses in certain sectors, particularly manufacturing.


  5. Disputes Over Dairy Trade


    - While the agreement benefits U.S. farmers, Canadian dairy producers have raised concerns about market access changes affecting their industry. Some Canadian politicians and farmer groups have argued that these changes threaten domestic agricultural stability.

Overall...


The USMCA represents a significant evolution of North American trade relations. While it retains much of NAFTA’s framework, it introduces critical changes aimed at addressing long-standing concerns about labour rights, manufacturing, and digital trade. The agreement has strengthened North American economic ties and modernised trade policies, particularly in the automotive and technology sectors.


However, challenges remain. Some industries have faced increased production costs, while environmental and labour rights activists argue that enforcement mechanisms need to be stronger. Political challenges remain too.


Now in his second term, Trump has shifted away from the positive outlook after the renegotiation from NAFTA to USMCA. Instead, his early weeks in office have been dominated by repeated threats to introduce tariffs of 25% on all imports from Canada and Mexico. He argues that both countries have failed to prevent the movement of illegal drugs, particularly fentanyl, and unauthorised migrants into the United States. Canada and Mexico, however, insist they want to cooperate with the US to tackle these issues and avoid a trade dispute.


Despite these tensions, the USMCA continues to regulate many aspects of trade and economic relations between the three nations, including agriculture, digital services, and investment protection. The agreement is due for review by July 2026, giving all three countries an opportunity to propose changes. As with many trade agreements, new challenges have emerged since its implementation, including concerns over drug trafficking and migration. If the US imposes new tariffs before renegotiating the USMCA, it would likely breach the agreement’s terms. To justify such a move, President Trump would need to use emergency economic powers under US law. In response, both Canadian Prime Minister Justin Trudeau (who is stepping down) and Mexican President Claudia Sheinbaum have threatened retaliatory measures and the tariffs have been postponed.


It remains to be seen whether the three leaders will reach an agreement on these contentious issues. If they do, they may then be able to shift their focus towards less controversial aspects of their economic relationship over the next 18 months.
