In 1930, the United States enacted the Smoot-Hawley Tariff Act, prompting Canada to raise duties on many American goods amid growing trade tensions. Nearly a century later, the two neighbours are locked in a trade war with a direct link to that Great Depression-era confrontation. In July 2026, the Trump administration invoked Section 338 of the 1930 Act—an obscure provision that had never previously been used—to impose additional duties on selected Canadian imports.
The measure came into force on 22 August, imposing a 50 per cent tariff on specified Canadian goods worth C$27.6 billion. Ottawa has struck back with dollar-for-dollar counter-tariffs on selected U.S. goods due to take effect on 8 September, while duties on American steel and aluminium will rise from 25 to 50 per cent. Looming large is Washington’s threat to levy a 50 per cent tariff on Canadian cars, trucks and automotive parts from 1 January 2027. Such a move would put considerable pressure on an industry built around an integrated North American production system in which components, raw materials and semi-finished vehicles routinely cross borders multiple times before reaching the market.
Political arguments surrounding the dispute reflect a divide over the role of protectionism in international trade. Supporters of the White House’s approach argue that tariffs can increase American bargaining power to secure more favourable trade terms from trading partners by reducing reliance on foreign production and protecting domestic industry. Critics argue that such policies are economically counterproductive, particularly when imposed on an essential ally whose economy is deeply intertwined with that of the United States. The economic burden of a tariff does not fall neatly on the foreign producer: importers, manufacturers, retailers and, ultimately, consumers may absorb some or all of the expense.
A tariff is intended to protect domestic producers by making imported goods more expensive, yet the cost of that protection is distributed across the wider economy. Importers may pass higher costs on to consumers, while domestic firms that rely on imported raw materials, machinery or intermediate goods face higher production costs themselves. In this sense, a tariff does not simply transfer advantage from foreign producers to domestic ones; it redistributes costs and benefits among different domestic actors, some of whom may be the very producers the policy is intended to protect. The policy may therefore strengthen one part of a domestic industry while weakening another, illustrating the broader difficulty of using economic pressure as a precise political instrument when supply chains and economic interests cross national and sectoral boundaries.
For Canada, the standoff has revived a more fundamental debate about the strategic risks of relying so heavily on a single export market. More than 70 per cent of Canadian merchandise exports still go to the United States, making diversification difficult but increasingly necessary as a matter of economic resilience. Prime Minister Mark Carney faces a delicate balancing act: Canada must preserve a functional relationship with Washington while simultaneously making the case that its economy cannot remain excessively vulnerable to abrupt changes in American trade policy. For consumers, the response has included calls to buy Canadian-made products and reduce spending on U.S. brands, while businesses have looked to diversify their supply chains by finding suppliers outside the United States. Yet the push to “buy local” reveals the same problem as the tariff war itself: in an economy built on cross-border supply chains, it is increasingly difficult to separate domestic interests from foreign ones.
If a domestic alternative costs only slightly more, the premium can be justified as a contribution to that broader objective. But as the price difference widens—or if the domestic product is perceived as inferior—the limits of economic patriotism become clearer. The Bank of Canada’s 2025 Canadian Survey of Consumer Expectations found that three-quarters of respondents were unwilling to pay more than 10 per cent extra for a made-in-Canada product. Other surveys have likewise found a preference for domestic goods alongside an attentiveness to price. These findings are not necessarily at odds; consumers may place genuine value on domestic production while still weighing that preference against the cost of a purchase. Support for Canadian-made goods, in other words, need not imply an unlimited willingness to pay a premium for them.
This gap between what consumers say they value and what they ultimately choose to buy is often described as the attitude–behaviour gap. Country of origin can influence consumer attitudes and purchasing decisions, but its effect depends on how strongly national preference shapes choices at the point of purchase. This is closely related to what researchers describe as consumer ethnocentrism—the tendency to favour domestic products based on the belief that doing so benefits one’s country. Political pressure can reinforce such preferences, but sustained changes in consumption ultimately depend on whether alternatives can meet expectations of price, quality, convenience and availability.
This is where country of origin becomes an important, but imperfect, guide. Modern production is organised through value chains that routinely cross borders: design, finance, manufacturing, ownership and retail may all be distributed across different economies. A label can identify where a product was made without revealing where its value was created, who captured the gains or how many economies contributed to it. The same applies to political purchasing: consumers may seek to direct economic pressure at a particular country or company even when the underlying commercial relationships are more dispersed. National origin therefore remains a powerful shorthand through which consumers can express economic and political preferences, but it is an increasingly imperfect guide to the interests and economic relationships they are actually seeking to influence.
“Local” is not only a geographic category but a relational one: local to whom and meaningful in relation to what? It can describe a place of production, but it can also describe a place of belonging. For one person, buying local may mean supporting businesses in the city where they live. For another, it may mean buying products from the country where they were born, the region their family comes from or the culture with which they identify. An Egyptian abroad, for instance, may attach particular meaning to a product from Egypt when encountering it in their country of residence, where it can evoke an even stronger sense of national identity, familiarity and connection to home.
This is particularly visible as Egyptian manufacturers expand their presence in the global market, with the apparel sector moving towards more diversified and higher-value products while investing in technology, quality and compliance with international standards. Egypt’s apparel exports rose by 14% in the first seven months of 2026 to $2.14 billion, reflecting the sector’s growing reach. Importantly, foreign-invested companies accounted for 37.5% of apparel exports during the same period, worth around $802 million, so an Egyptian-made product encountered abroad may not carry an Egyptian brand name.
The same logic applies at the level of states. When economic pressure makes one trading relationship more costly or uncertain, the incentives to seek alternatives extend beyond individual firms and across borders. The question is therefore not only who absorbs the cost of a tariff, but where the trade that becomes more difficult will go, and what new relationships may emerge in its place. Canada’s response is already beginning to point in that direction. China is one potential beneficiary, not because Canadian businesses must choose it over the United States, but because it offers something increasingly valuable: another large market for Canadian exports and another source of goods, components and industrial inputs. Canada had already been seeking to expand commercial ties with China, including by pursuing greater access for some Canadian agricultural exports. The current dispute gives that diversification a stronger economic rationale. Yet this relationship is also part of the political tension behind the trade war. Washington has long been concerned that Canada could become a route through which Chinese goods and technologies enter the U.S. market indirectly, particularly in strategically sensitive sectors such as electric vehicles and batteries. From the American perspective, closer Canada–China trade can therefore appear not simply as a Canadian response to U.S. pressure, but as a potential challenge to the effectiveness of that pressure. If access to the American market can become uncertain, maintaining viable relationships elsewhere becomes less a political preference than a form of economic insurance.
Mexico is watching the dispute closely for a different reason. Its integration with the United States and Canada was institutionalised through the North American Free Trade Agreement (NAFTA), which came into force in 1994, and later replaced by the United States–Mexico–Canada Agreement (USMCA) in 2020. Like Canada, Mexico is therefore deeply integrated into the North American economy, but its relationship with the United States is even more concentrated in manufacturing and cross-border production. Roughly 92 per cent of Mexican exports to the United States are manufactured goods, much of them tied to integrated North American supply chains. Canada’s experience therefore offers Mexico a preview of the political risks that can accompany such integration: access to the U.S. market can become leverage in negotiations that extend beyond trade, while tariffs imposed on one country can disrupt production across the region. Yet this interdependence also gives Mexico leverage of its own. American manufacturers and consumers rely on Mexican inputs and production, meaning that economic integration creates costs for both sides when trade barriers rise. For Mexico, the lesson is therefore not simply to reduce its dependence on the United States, but to recognise the value—and vulnerability—of that dependence while developing alternative markets and suppliers where doing so strengthens its bargaining position.
There is an important irony in this process: policies intended to reshape trade can end up reshaping the relationships on which trade depends. As businesses respond to uncertainty by finding alternative suppliers, entering new markets or developing different logistics routes, they acquire commercial relationships and capabilities that may outlast the policy that prompted them. Even if tariffs are later reduced, some of these adjustments may remain economically useful. In this way, trade policy can have effects that extend beyond the cost of an individual shipment, gradually altering where firms source, which markets they serve and how supply chains are organised.
The lesson of the tariff war is not that countries should choose between economic self-sufficiency and globalisation. It is that resilience comes from knowing where dependence is useful, where it is dangerous and where alternatives are worth the cost. Recent disruptions, from pandemics and wars to extreme weather and shipping interruptions, have made the consequences of concentrated supply chains harder to ignore. Global value chains are already adapting: companies are diversifying suppliers, production sites and export markets in response to geopolitical tensions, trade policy and supply-chain uncertainty. The World Trade Organization has described this broader shift as “re-globalisation”—a reorganisation of international integration rather than its retreat. Buying local can be meaningful, but only if we recognise what “local” actually contains: foreign capital, imported materials, international technology, cross-border labour and markets that extend far beyond the place named on the label. The future of “buying local” may not be about buying less from the world, but about understanding how much of the world it took to make it local.
