Beyond Free Trade: How CUSMA 2026 Could Rebuild North America’s Manufacturing and Investment Map

North America is entering a new phase of economic integration in which trade policy, industrial strategy and investment decisions are becoming inseparable. The 2026 review of the Canada–United States–Mexico Agreement, known as CUSMA in Canada and USMCA in the United States, has therefore become far more consequential than a routine assessment of a trade pact. It is emerging as a test of whether the continent can preserve one of the world's most deeply integrated production systems while responding to tariffs, geopolitical competition, supply-chain vulnerabilities and the accelerating race for advanced manufacturing. 

The agreement entered into force on 1 July 2020, replacing NAFTA, and its first mandatory joint review took place on 1 July 2026. Crucially, the review was not an expiry date. CUSMA remains in force until 2036 unless the parties agree otherwise. However, the United States declined to renew the agreement in its current form, opening the door to further negotiations over its future. 

That decision has introduced a new layer of uncertainty for companies whose business models depend on the seamless movement of components, raw materials and finished products across the continent. For manufacturers, the question is no longer simply whether goods can cross borders under preferential terms. The bigger question is whether North America can create a more strategically integrated industrial base capable of competing with China and other manufacturing centres. Few regions demonstrate economic interdependence as clearly as North America. A vehicle assembled in the United States can contain components manufactured in Mexico and Canada before crossing borders several times during production. Aerospace, electronics, metals, agriculture, energy and advanced technology industries similarly rely on interconnected regional supply chains. 

The scale is enormous. Canada, Mexico and the United States together represented a market of about 517 million consumers and combined GDP of roughly US$48.8 trillion in 2025. Canada and the United States alone exchanged almost C$3.5 billion in goods and services every day during the year. Since CUSMA came into force, Canada–US goods and services trade has increased by more than 27%, while Canada–Mexico trade has risen by 56.6% when comparing 2025 with 2019. These figures explain why businesses are watching the negotiations so closely. Changing the rules governing regional trade would not simply affect exporters. It could alter where companies build factories, source components, locate research operations and commit billions of dollars in long-term capital. 

The United States has made manufacturing reshoring and the reduction of trade deficits central themes of its approach to the review. Washington has indicated that it wants to address what it considers shortcomings in the existing agreement, while discussions with Mexico have focused on economic security, labour, agriculture, steel and aluminium, electronic payment services and automobiles. Both sides have also emphasised the importance of expanding North American manufacturing and strengthening regional supply chains. For manufacturers, this could encourage a new form of regionalisation. Instead of simply searching for the lowest-cost production location, companies may increasingly prioritise factories that provide reliable access to the entire North American market. 

Mexico is particularly important to this equation. Its established manufacturing ecosystem, proximity to the United States and participation in CUSMA have helped it become a major platform for industries ranging from automobiles and electronics to industrial equipment. Yet investment decisions are becoming more cautious as businesses assess tariff uncertainty and the future terms of continental trade. Reuters reported in September that new foreign investment in Mexico had begun to stall as companies became increasingly concerned about uncertainty surrounding USMCA. At the same time, Mexico's manufacturing expansion continues to create opportunities in industrial property and infrastructure, demonstrating the contradictory forces currently shaping the market. 

Canada enters the new trade era with a different set of strengths. Its enormous energy and natural-resource base, skilled workforce and proximity to the US market give it strategic importance in an increasingly security-conscious global economy. Ottawa has made clear that it wants CUSMA renewed and has stressed the importance of predictable access to the American and Mexican markets. At the same time, Canada is seeking to address sector-specific tariffs affecting industries including steel, aluminium, automobiles and lumber. 

The automotive industry illustrates the stakes. Canadian officials and North American vehicle manufacturers have argued that maintaining a strong integrated auto sector is essential for investment, manufacturing competitiveness and innovation. The industry's future will depend increasingly on how the three countries approach electric vehicles, batteries, critical minerals and cross-border component production. 

This could give Canada an opportunity to reposition itself not merely as a supplier of commodities, but as a critical part of North America's next generation of industrial infrastructure. The greatest impact of the CUSMA review could ultimately be felt not in trade statistics but in boardrooms. Manufacturing investments typically involve commitments lasting decades. A new factory, semiconductor facility, battery plant or logistics centre cannot easily be relocated when tariff policy changes. Investors therefore need confidence that the rules governing continental market access will remain sufficiently predictable. 

That is why the review could influence capital allocation across all three countries. If policymakers establish clearer long-term rules, businesses may accelerate investments designed around North American supply chains. If uncertainty persists, companies could diversify production towards other regions or delay major projects. The result may be a more strategic version of nearshoring. Rather than simply moving production closer to the US consumer, companies could build three-country supply chains designed around regional resilience, domestic-content requirements and access to critical resources. 

CUSMA's future will also be shaped by industries that were far less prominent when the agreement was negotiated. Artificial intelligence, data centres, advanced semiconductors, digital services and automated manufacturing are creating new demands for electricity, infrastructure and specialised skills. North America's competitiveness will increasingly depend on whether these technologies can be supported by integrated energy and industrial systems. Digital trade provisions, data flows and emerging technologies therefore matter alongside traditional questions about tariffs and manufactured goods. 

The Canadian government itself has highlighted digital trade, artificial intelligence and energy stability as examples of developments that make adaptation of the continental trade framework increasingly important. This could transform CUSMA from a conventional free-trade agreement into part of a broader North American economic-security framework. There is also a geopolitical dimension. North American governments increasingly view supply chains through the lens of economic security. Dependence on distant suppliers for strategically important products can create vulnerabilities during geopolitical crises. 

The emerging CUSMA discussions therefore have implications beyond Canada, Mexico and the United States. A stronger regional manufacturing network could reduce reliance on external suppliers in sectors such as semiconductors, batteries, defence equipment, critical minerals and advanced industrial technologies. For investors, this creates opportunities in infrastructure supporting manufacturing rather than manufacturing alone. Industrial parks, warehouses, ports, railways, power generation, transmission networks and specialised commercial property could all benefit if companies continue to regionalise their supply chains.
