A tariff dispute that began with higher costs at the border is increasingly changing decisions made inside Canadian factories, warehouses and boardrooms. The Bank of Canada says the upheaval in Canada-U.S. trade is forcing businesses to adjust to a new economic reality, with some companies changing suppliers, exploring new markets and reconsidering where goods should be produced. The shift matters because decades of relatively open North American trade created deeply integrated supply chains that cannot simply be rearranged overnight. Although much Canada-U.S. commerce remains protected from tariffs, uncertainty over the trading relationship has become significant enough that the central bank believes companies may continue rethinking production, sourcing and investment decisions for years rather than months.
The Bank Says This Is Becoming a Structural Change
The Bank of Canada’s September 24 assessment goes considerably further than saying tariffs make imported goods more expensive. It argues that tariffs and other trade barriers can change where goods and services are produced in the first place. A U.S. buyer facing a tariff on a Canadian product may search for an American alternative. A Canadian company buying U.S. inputs may seek a domestic supplier or one in another country. Once companies begin reorganizing supply chains around those decisions, the effects can last well beyond the initial tariff announcement.
That distinction is important. Temporary price increases can disappear if a tariff is removed, but a company that has qualified a new supplier, signed contracts in another market or invested in production equipment somewhere else may not immediately reverse course. The Bank says uncertainty surrounding the future Canada-U.S. trading relationship could therefore keep companies reassessing both where they produce and whom they purchase from. It also warns that weaker demand for Canadian exports can ultimately reduce investment, employment and economic activity if the adjustment becomes prolonged.
Decades of U.S. Integration Make the Adjustment Complicated
Canada is particularly exposed to this kind of disruption because its commercial relationship with the United States is unusually deep. Global Affairs Canada reported that roughly 72% of Canadian goods exports went to the United States in 2025, while 53% of Canadian service exports were sold there. Geography, similar business practices and decades of trade liberalization have encouraged companies to build operations around easy access to customers and suppliers on both sides of the border.
The supply-chain links run deeper than the final destination shown on an export label. The Bank of Canada estimates that U.S.-sourced content accounts for about one-fifth of the total value of Canadian exports to the United States on average. That means a Canadian manufacturer losing U.S. orders can simultaneously need fewer American components, creating a feedback effect through the supply chain. Physical infrastructure reflects that integration as well: the Bank notes that more than 2.1 million commercial trucks cross the Blue Water Bridge between Sarnia, Ontario, and Port Huron, Michigan, annually. Reorganizing systems built around flows of that scale involves far more than simply selecting a different vendor from a catalogue.
Canadian Companies Have Already Started Changing Suppliers
There is evidence that sourcing patterns have already moved. The Bank of Canada found that imports from the United States declined after the trade disruption began while imports from other countries increased. About 80% of the initial decline in the U.S. share of Canadian imports occurred in sectors affected by Canadian counter-tariffs. Some of that movement later reversed when most counter-tariffs were removed, showing that price incentives still matter, but the Bank also identified broader attempts by companies to diversify suppliers and reduce their exposure to future trade shocks.
The change is visible outside heavy industry as well. Reuters reported in September that Canadian grocers were developing new supply relationships as trade tensions and consumer demand for non-U.S. products intensified. One Ontario chain shifted strawberry sourcing from the United States to Quebec, while another retailer reported selling more produce sourced from Spain, Brazil and Honduras. U.S. suppliers remain important, particularly during Canada’s winter, but the example illustrates what supply-chain diversification looks like on the ground: purchasing managers who once relied heavily on one country are increasingly keeping alternatives available.
Manufacturing Is Feeling the Pressure More Than Most Sectors
The effects are not evenly distributed across the economy. Statistics Canada’s third-quarter 2026 Canadian Survey on Business Conditions found that 32.2% of businesses expected U.S. tariffs on Canadian imports to negatively affect them over the next 12 months. Among manufacturers, the proportion rose to 49.7%. Transportation and warehousing businesses were close behind at 47.3%, while 45.1% of wholesale businesses expected negative effects. Those industries sit particularly close to the movement, production and distribution of physical goods across borders.
The Bank of Canada has highlighted autos, steel, aluminum and lumber as sectors that have been hit especially hard by U.S. trade measures. Manufacturing can also be more difficult to redirect than commodity production. Canadian oil, minerals and agricultural products have potential customers around the world, while a factory producing specialized components may depend on specific customers, technical standards and established North American supply networks. That helps explain why the Bank says manufacturers can face more difficulty finding replacement markets even when opportunities exist elsewhere. The problem is therefore not simply finding another country willing to buy something; in many cases, an entirely new commercial relationship must be built.
Avoiding U.S. Tariff Exposure Can Come With New Costs
Changing suppliers can reduce dependence on one trading relationship, but the Bank cautions that diversification is not automatically cheaper. Companies have increasingly imported some goods directly into Canada rather than routing them through the United States, while other businesses have sought completely new sources. The Bank says new sources of supply tend to be more expensive than those used before the tariff dispute and that direct shipping arrangements can also add costs. Building relationships with new overseas customers and suppliers takes time and effort as well.
Some of those expenses are already reaching customers. Statistics Canada found that 27.4% of businesses had passed tariff-related cost increases on to customers during the 12 months preceding its third-quarter survey. Another 37.7% said they had absorbed the increases rather than passing them along, while 34.9% reported experiencing no tariff-related cost increase. Looking ahead, 30.4% said they were very or somewhat likely to pass tariff-related increases on during the next 12 months. The numbers show the uncomfortable trade-off companies face: a more diversified supply chain may be safer, but resilience itself can carry a price.
The Bigger Question Is Where Future Investment Goes
Supplier contracts can sometimes be changed relatively quickly. Decisions about factories, machinery and long-term production capacity are much harder to reverse. Bank of Canada Governor Tiff Macklem has described business adjustment as progressing from reassessment, to practical adaptation, and eventually to more transformative changes involving new products, technology and markets. Those longer-term investments determine not only whom a company buys from but where future economic activity takes place.
There have recently been encouraging investment numbers. Macklem said Canadian business investment increased at an annualized 8.8% rate in the second quarter of 2026 as companies invested in productivity, technology and broader customer bases. The renewed tariff escalation, however, has complicated that picture. The Bank warned that fresh uncertainty could again encourage businesses to postpone investment and hiring decisions. Macklem estimated that, if the newest U.S. tariffs remain in place, Canadian fourth-quarter growth could be roughly halved to below 1%. Reuters separately reported the same warning after his September 21 speech. A company uncertain about its access to its largest export market has a strong reason to think carefully before committing capital for the next decade.
Canada’s Shift Toward Other Markets Is Showing Up in Trade Data
Diversification is no longer visible only in corporate plans. Statistics Canada reported that Canadian merchandise exports to countries other than the United States jumped 7.4% in July 2026, reaching a record $25.6 billion after a third consecutive monthly increase. Non-U.S. destinations accounted for 33.7% of Canadian merchandise exports that month. Shipments to the Netherlands, China and Germany were among the major contributors to the increase. At the same time, exports to the United States fell 6.6% in July, although much of that monthly decline reflected lower crude-oil and gold shipments.
The trend predates July. Global Affairs Canada found that non-U.S. exports grew 11.1% in 2025 and reached their largest share of Canadian exports since 1981, although commodities such as gold, crude oil, aluminum and canola were important drivers. Macklem also reported that non-energy exports climbed 14.5% in the second quarter of 2026 to their highest level since early 2025. He cautioned that temporary factors contributed to the rebound, but said Bank surveys and outreach indicated that deliberate decisions to reduce tariff exposure and change sourcing strategies also played a role.
Exporters Are Increasingly Planning for a World Beyond One Market
Corporate intentions suggest the diversification push could continue. Export Development Canada’s mid-year Trade Confidence Index found that 72% of Canadian exporters planned to enter new markets during the next two years, up from 65% five months earlier. Europe was identified as an attractive destination by 31% of respondents and the Asia-Pacific region by 20%. The survey also found companies responding to weaker U.S. exposure in several ways: 29% were increasing domestic sales, 22% were sourcing locally and 19% were expanding into additional export markets.
Those figures do not point to a wholesale abandonment of the United States. EDC found that 81% of the exporters it surveyed were still active in the U.S. market, reflecting its proximity, size and deeply integrated supply chains. The survey also deserves an important timing caveat: responses were collected between June 8 and July 27, before another round of U.S. tariffs was imposed in August. The Bank’s more recent assessment nevertheless points in the same general direction. It says Canadian exporters are broadening their options, frequently by selling more to overseas customers they already know rather than immediately establishing operations in completely unfamiliar markets.
The Likely Outcome Is Diversification, Not a Clean Break With the U.S.
For all the attention on new suppliers and overseas markets, the Bank of Canada is not predicting the disappearance of the Canada-U.S. economic relationship. The United States remains Canada’s largest trading partner by a wide margin, and the Bank notes that the Canada-United States-Mexico Agreement continues to protect many Canadian goods and services from tariffs. Geography alone gives businesses powerful reasons to preserve cross-border relationships whenever they remain commercially workable. Canada has also faced lower tariff exposure than many other countries in some areas, potentially leaving Canadian firms with advantages over certain foreign competitors seeking access to U.S. customers.
What appears to be changing is the willingness of companies to rely on that relationship as confidently as they once did. Macklem said the newest tariff measures directly cover products representing about 5% of Canada’s goods exports to the United States, meaning their immediate economy-wide effect is relatively contained. Yet the uncertainty surrounding future policy can influence a far larger group of businesses by affecting investment, hiring, supplier contracts and expansion plans. The result may be an economy that continues trading heavily with the United States while deliberately building backup suppliers, customers and production options elsewhere. That is the deeper transformation the Bank is now watching.
