Canada, Mexico, and the United States. The new continental supply network – interAlcaldes Magazine

North America’s economic border is no longer a line, but a network of mines, factories, design centers, logistics corridors, customs facilities, and cities. A Canadian mineral can be processed in the United States, incorporated into a Mexican component, and ultimately become a car or medical device for the continental market.

This integration is no longer merely a nearshoring promise. In 2025, U.S. transborder freight flows with Canada and Mexico reached $1.586 trillion, nearly 30% of all U.S. trade in goods. The thesis is clear: North America already operates as a production platform, but it is not yet governed or equipped as a single network.

The July 1, 2026 USMCA review exposed that contradiction. The United States did not agree to renew the agreement in its current form, but the treaty was not terminated and remains fully in force through 2036. Without consensus to extend it for another 16 years, the reviews will become annual. Trade continues; what has increased is uncertainty over the rules that will shape its next stage.

From linear chains to a regional platform

For decades, integration was described through a simple division of labor: Canada supplied energy and natural resources; the United States provided capital, technology, and market access; and Mexico contributed manufacturing and competitive costs. That interpretation is now inadequate. All three countries design, manufacture, finance, transport, and consume, although with different capabilities. The advantage comes not from assigning each nation a rigid role, but from connecting their specializations without interruption.

“The North American factory no longer belongs to one country; it depends on the coordination of three territories.”

The Canada–Mexico Action Plan 2025–2028 confirms that the relationship need not always run through Washington. The two governments proposed cooperation on maritime corridors, port digitalization, cargo traceability, energy infrastructure, sustainable mining, and agrifood chains. North America is beginning to recognize itself not merely as two bilateral relationships organized around the United States, but as a network with direct links among all its nodes.

Canada holds a decisive position: Windsor–Detroit is one of the main automotive freight corridors, while its energy and mineral resources supply industries across the continent. Ottawa has also placed U.S. tariffs on steel, aluminum, automobiles, and lumber on the review agenda. No network is stable with unpredictable barriers in strategic industries.

The USMCA review is a competitiveness test

After July 1, bilateral Mexico–U.S. talks addressed automotive rules of origin, steel and aluminum, economic security, labor, agriculture, and electronic payments. These issues will determine permitted nonregional content, which industries attract investment, and the predictability of long-term production.

The region must avoid two extremes: allowing goods from non-USMCA countries to receive treaty benefits without creating sufficient regional value, or tightening the rules until continental production becomes more expensive and less flexible. The U.S. International Trade Commission found mixed effects from the automotive rules of origin: they supported certain parts and materials segments, but also raised costs and prices. Deeper integration does not mean more regulation; it means better regulation.

Municipalities sustain what trade agreements promise

The USMCA is negotiated by federal governments, but it succeeds—or stalls—in specific territories: the border cities of Nuevo Laredo, Ciudad Juárez, and Tijuana; the industrial nodes of Apodaca, Ramos Arizpe, and Querétaro; and Jalisco’s El Salto–Tlajomulco metropolitan corridor.

Laredo, Texas, handled more than $296 billion in freight in 2025. That scale shows why a congested road, a slow customs facility, a power outage, or a delayed municipal permit is no longer a local problem: it can interrupt a continental supply chain.

“Nearshoring is won at the negotiating table but lost in the last mile: water, energy, housing, mobility, and permits.”

For Mexico, the opportunity is not simply to open more industrial parks. Municipalities must plan land use, secure water and energy, connect housing with jobs, protect logistics corridors, digitize permitting processes, and develop talent with universities and businesses. Without that foundation, investment may arrive before local infrastructure is capable of sustaining it.

The global lesson is to govern corridors

The European Union offers a useful reference, not a template to copy. Its TEN-T network coordinates nine transport corridors, establishes common standards, incorporates urban nodes, and assigns coordinators to align cross-border investment. North America has no mechanism comparable in scale and mandate for prioritizing border crossings, railways, energy, ports, data, and climate resilience.

Competitive corridors require continuity among countries, states, provinces, and municipalities, as well as shared indicators for border crossings, electricity, water, emissions, security, and talent.

What remains unresolved

The region must turn the USMCA review into an agenda for infrastructure and trust: clear rules for nonregional inputs, customs and digital interoperability, coordinated investment in border crossings and energy, and mechanisms ensuring that industrial communities receive benefits proportional to the costs they absorb.

The continental network already exists in factories, highways, and ports. Its future will depend on something less visible: the institutional capacity to coordinate territories. If Canada, Mexico, and the United States already produce as a region, are their governments and municipalities prepared to plan as a region as well?
