America First: Policy, Not Just a Slogan

The geopolitical landscape of North American trade is bracing for a period of significant volatility as the United States prepares for the scheduled review of the United States-Mexico-Canada Agreement (USMCA). At the center of this transition is Jamieson Greer, the nominee for U.S. Trade Representative, who has signaled a rigorous adherence to the “America First” doctrine, framing it not as a rhetorical device but as a concrete operational policy.

For Canada and Mexico, the upcoming review represents more than a routine administrative check. It is a critical juncture that could redefine the flow of goods, services and investment across the continent. The administration’s current trajectory suggests a move away from the multilateral cooperation that characterized previous eras, shifting instead toward a transactional, bilateral approach designed to maximize U.S. Economic leverage.

The tension stems from a fundamental difference in how the agreement is viewed. While the USMCA provided a degree of stability following the turmoil of the NAFTA renegotiations, the current U.S. Leadership views the agreement as a living document that must be aggressively optimized to reduce trade deficits and repatriate manufacturing. This shift in posture indicates that the “America First” framework will be the primary lens through which every chapter of the trade deal is scrutinized.

The 2026 USMCA Review: The ‘Sunset Clause’ Pressure

The USMCA contains a unique and potentially disruptive mechanism known as the “sunset clause.” Under Article 34.7 of the agreement, the three member nations are required to conduct a joint review of the treaty every six years to determine if it should continue in force. With the first major review scheduled for 2026, the clock is ticking for North American partners to align their interests with Washington’s expectations.

Unlike traditional trade agreements that remain in effect indefinitely unless terminated, the USMCA’s structure creates a recurring window of uncertainty. If the three nations cannot reach a consensus during the review, the agreement could theoretically face a path toward expiration, although a total collapse is viewed as unlikely given the deep integration of North American supply chains. However, the 2026 deadline provides the U.S. With significant leverage to demand concessions in exchange for a confirmation of the agreement’s extension.

Industry analysts suggest that the U.S. May apply this review to address lingering grievances regarding automotive rules of origin, dairy market access in Canada, and labor enforcement in Mexico. By treating the review as a renegotiation rather than a confirmation, the U.S. Can push for terms that more directly benefit domestic producers.

Jamieson Greer and the Shift to Transactional Trade

The nomination of Jamieson Greer as the U.S. Trade Representative (USTR) underscores a commitment to a more assertive trade posture. Greer, who has a history of supporting aggressive tariff strategies and the prioritization of national interests over global trade norms, is expected to lead the U.S. Delegation into the 2026 review with a clear mandate: the “America First” policy is the guiding principle, not a slogan.

This distinction is critical. When a phrase like “America First” is treated as a slogan, it serves as a political signal. When it is treated as a policy, it becomes the metric for success. In practical terms, this means that the USTR’s office will likely prioritize the reduction of the U.S. Trade deficit over the maintenance of broad regional stability. Greer’s approach is expected to be characterized by “bilateralism,” where the U.S. Deals with Canada and Mexico individually to maximize its bargaining power, rather than treating the USMCA as a tripartite partnership.

This strategy mirrors the broader national security goals of the administration, which emphasize economic resilience and the decoupling of critical supply chains from adversarial nations. By tightening the rules within North America, the U.S. Aims to create a “fortress” economy that is less dependent on overseas imports, particularly from China.

Key Areas of Contention in the Coming Review

As the 2026 review approaches, several specific friction points are likely to dominate the discussions. These areas represent the intersection of economic policy and national security:

• Automotive Rules of Origin: The USMCA requires a high percentage of a vehicle’s components to be made in North America to qualify for zero tariffs. The U.S. May seek to tighten these requirements further to force more production onto U.S. Soil.
• Energy Exports: The U.S. Has previously expressed concerns over Mexico’s energy policies, which have favored state-owned companies over private U.S. Investors. This is expected to be a major point of contention during the bilateral talks.
• Dairy and Agriculture: Canada’s supply management system for dairy remains a perennial thorn in U.S.-Canada relations. Washington is likely to demand greater access to the Canadian market for U.S. Farmers.
• Labor and Environmental Standards: The U.S. Will likely push for stricter enforcement of labor laws in Mexico to prevent “social dumping,” where lower wages in Mexico draw manufacturing away from the U.S.

The impact of these negotiations will be felt most acutely by the logistics and manufacturing sectors. A shift in the rules of origin or the imposition of new tariffs could force companies to redesign their entire supply chains, leading to short-term costs and long-term shifts in where factories are located.

What This Means for Canada and Mexico

For Ottawa and Mexico City, the challenge is to manage a relationship with a superpower that is increasingly comfortable with economic disruption as a tool of diplomacy. Both nations have historically relied on the predictability of trade rules to attract foreign investment. The prospect of a “policy-driven” America First approach introduces a level of unpredictability that can deter long-term capital expenditure.

Canada is likely to emphasize the integrated nature of the energy and automotive sectors, arguing that destabilizing the USMCA would harm U.S. Consumers through higher prices. Mexico, meanwhile, is navigating a complex internal political landscape while trying to maintain its status as the primary manufacturing hub for the U.S. Market. Both nations are expected to increase their diplomatic efforts to frame their economic successes as wins for the U.S. As well.

The strategy for these partners will likely involve presenting “win-win” scenarios that align with the U.S. Goal of reducing dependence on Asia. By positioning North America as the premier alternative to Chinese manufacturing, Canada and Mexico hope to secure a favorable outcome during the 2026 review.

Summary of the USMCA Review Framework

The Road to 2026: Next Steps

While the formal review process is still some time away, the groundwork is being laid now. The appointment of the USTR and the issuance of new national security guidelines are the first indicators of the coming shift. Businesses operating across North American borders should start auditing their supply chains to identify vulnerabilities to potential tariff changes or revised rules of origin.

The next critical checkpoint will be the formal initiation of the review consultations, which are expected to begin in the lead-up to the 2026 deadline. Until then, the market will be watching the USTR’s early actions in other trade disputes as a bellwether for how the USMCA review will be handled.
