Check What’s Feeding the Aircraft Carrier. - URL: https://www.nastycanuck.ca/canada-rowboat-aircraft-carrier-supply-lines/ - Published: 2026-09-30T15:34:20.000Z - Updated: 2026-10-06T18:41:21.000Z - Description: The U.S. economy dwarfs Canada’s. That doesn’t make it self-sufficient. Energy, fertilizer, aluminum, lumber and water tell a more complicated story. - Author: Nasty Canuck Editorial Desk - Tags: The Woodshed, Canada-U.S. Relations, Canadian Economy, Trade, Trade Diversification, Economic Sovereignty *A senior White House trade adviser says Canada is a rowboat facing an American aircraft carrier. The size difference is real. So are the supply lines running through Canada.* Hamilton is not a metaphor. Starting October 9, Stelco [plans to indefinitely idle its cold-rolled and coated operations in Hamilton](https://www.reuters.com/business/cleveland-cliffs-idle-output-canada-steel-plant-blames-tariffs-says-cbc-2026-09-28/), with up to 500 workers affected as production shifts toward Lake Erie Works in Nanticoke. The company has pointed to U.S. tariffs, weaker downstream demand and continued import pressure as part of the problem. That is what a trade fight looks like after it leaves the podium: production decisions, disrupted supply chains and people wondering what happens to their paycheques. A senior White House trade adviser recently [compared Canada to a rowboat opening fire on an aircraft carrier](https://rdnewsnow.com/2026/09/10/the-latest-on-the-escalating-trade-war-between-canada-and-the-united-states/). “The carrier will notice. The rowboat will sink,” he wrote. It is a memorable metaphor, and it gets one important thing right. The United States is the much larger economy. Canada is also the more exposed partner: in 2025, [67.2 per cent of Canadian goods-and-services exports went to the United States](https://international.canada.ca/en/global-affairs/corporate/reports/chief-economist/state-trade/2026). What the metaphor leaves out is the machinery around the ships. An aircraft carrier is powerful because a much larger system keeps it supplied. The Canadian and American economies work the same way: pipelines, transmission lines, railways, refineries, sawmills, smelters, farms, fertilizer shipments and one very large river system tie the two countries together. The aircraft carrier may be bigger. It still has supply lines. ## The question is not size. It is substitution. Canada cannot wish away the asymmetry. Losing access to the U.S. market would hurt Canada more, proportionally, than the reverse. But American exposure is concentrated in particular inputs, regions and pieces of infrastructure, and “there is another supplier somewhere” is not the same thing as “this can be replaced tomorrow at the same price.” **Substitution has a clock and a cost.** Specifications matter. Existing plants matter. Pipelines, transmission lines, rail routes, growing seasons and long-term power contracts matter. The useful question is not who has the larger GDP. It is what has to change when a supply line moves. ## Some supply lines are welded into the map Energy is the clearest example. According to the [Canada Energy Regulator](https://www.cer-rec.gc.ca/en/data-analysis/energy-markets/market-snapshots/2026/market-snapshot-overview-of-2025-canada-us-energy-trade.html), Canada supplied 63.4 per cent of U.S. crude-oil imports in 2025, close to 100 per cent of imported natural gas, 97.9 per cent of imported natural-gas liquids and 81.3 per cent of imported electricity. Those are shares of imports, not total American consumption; the United States remains one of the world’s largest energy producers. But infrastructure does not rearrange itself because somebody gives a speech. The [U.S. Energy Information Administration](https://www.eia.gov/todayinenergy/detail.php?form=MG0AV3&id=62664) says Canadian crude accounted for 24 per cent of total U.S. refinery throughput in 2023\. Many American refineries, particularly in the Midwest and Rocky Mountain regions, are closely connected to Canadian pipelines and are designed to process heavier crude grades like those produced in Western Canada. Alternatives exist. Replacing millions of barrels at scale still means finding suitable crude, moving it through different ports or pipelines and getting it to refineries built around particular feedstocks. Potash is an even cleaner concentration story. The U.S. Geological Survey found that [about 90 per cent of U.S. net potash imports came from Canada in 2023](https://pubs.usgs.gov/publication/ofr20251047/full). Potash is fertilizer. A replacement supply has to exist in sufficient volume, arrive through a different logistics chain and still reach American farm country at a workable price. Aluminum shows why domestic replacement is not only a construction problem. The [U.S. Geological Survey’s 2026 mineral summary](https://pubs.usgs.gov/publication/mcs2026) puts U.S. net import reliance for aluminum at 60 per cent and lists Canada as its leading import source. Smelting aluminum also consumes enormous amounts of electricity. The Aluminum Association of Canada says electricity accounts for [about 30 per cent of Canadian smelter operating costs](https://developpementdurable.aluminium.ca/indicators/environnement/autre?locale=en), with 96 per cent of energy used at member production sites coming from hydroelectricity. Reuters reported earlier this year that another U.S. primary smelter [closed permanently after years of uneconomic power costs](https://www.reuters.com/markets/commodities/power-trumps-tariffs-another-us-aluminium-smelter-shuts-2026-02-18/). The United States can build more smelters. The harder part is finding very large amounts of reliable, competitively priced electricity to run them. ## Sometimes the supply chain looks like a two-by-four Forest products make the same point without a pipeline. Natural Resources Canada says [76 per cent of Canadian forest-product export value went to the United States in 2024](https://natural-resources.canada.ca/forests-forestry/state-canada-forests/state-canada-s-forests-annual-report-2025). From the American side, the National Association of Home Builders says Canadian lumber accounted for [about 74 per cent of the value of U.S. softwood-lumber imports in 2024](https://www.nahb.org/blog/2025/11/state-lumber-import-analysis). Canadian lumber is not magically superior to every American species. Different woods have different engineering properties. But the Canadian Wood Council notes that Canadian spruce-pine-fir is valued for characteristics including [straight grain, light weight, moderate strength and small knots](https://cwc.ca/articles/grades/). Builders can substitute species in many applications; doing so still involves grades, design requirements, mill capacity, logistics and price. Washington recently made the broader point itself. On September 8, a White House tariff revision [removed several Canadian products from a 50-per-cent tariff](https://www.whitehouse.gov/wp-content/uploads/2026/09/ANNEX-I-AUTO.pdf), including salt, Portland cement and toilet or facial tissue stock. Road salt, cement and toilet paper are not strategic weapons. They are useful reminders that supply chains become noticeable when somebody tries to price them out. Maple syrup makes the same point on a smaller scale. Canada produced [18.9 million gallons in 2025](https://agriculture.canada.ca/en/sector/horticulture/reports/statistical-overview-canadian-maple-industry-2025), more than three-quarters of world production. The United States produced 5.77 million gallons, led by Vermont, New York and Maine, while 64.7 per cent of Canadian maple export volume went south. This is not national security. It is breakfast. Corn syrup can fill a pancake bottle. It does not turn into maple syrup. ## Upstream is its own kind of leverage Some dependencies are geographical before they are commercial. The Columbia River rises in British Columbia and crosses into the United States before reaching the Pacific. For more than six decades, Canada and the United States have coordinated reservoirs under the Columbia River Treaty to support hydropower and manage flood risk downstream. The treaty did not expire in 2024\. It [has no fixed termination date](https://www.canada.ca/en/environment-climate-change/corporate/international-affairs/partnerships-countries-regions/north-america/canada-united-states-columbia-river.html); what changed after 60 years were the original assured flood-control arrangements. Under interim measures, [Canada is providing 3.6 million acre-feet of storage at Arrow Lakes for U.S. flood-risk management through 2027](https://2021-2025.state.gov/interim-measures-to-continue-columbia-river-treaty-coordination/). Canada says negotiations to modernize the treaty have been [paused since early 2025 as part of a U.S. State Department foreign-policy review](https://international.canada.ca/en/global-affairs/corporate/transparency/briefing-documents/parliamentary-committee/2025-10-30-faae). Oregon Public Broadcasting reported that the basin and its dams generate about [40 per cent of U.S. hydropower](https://www.opb.org/article/2025/03/14/us-pauses-columbia-river-water-sharing-agreement-with-canada/), while also supporting irrigation, flood management and commercial navigation in the Pacific Northwest. None of that gives Canada a faucet marked **AMERICA**. Treaties, reservoir operations, communities and ecosystems constrain both countries. But geography is still geography. Barbara Cosens, a University Distinguished Professor Emerita at the University of Idaho College of Law and an expert in water law, gave Oregon Public Broadcasting an old water-law saying: > “It’s better to be upstream with a shovel than downstream with a right.” That is not a proposal for a water war. It is a reminder that GDP is not the only form of leverage. ## Hamilton is the guardrail against overconfidence Canada should not turn any of this into a fantasy of invulnerability. When Cleveland-Cliffs acquired Stelco in 2024, Ottawa approved the deal subject to [binding five-year undertakings](https://www.canada.ca/en/innovation-science-economic-development/news/2024/10/ministerial-statement-on-the-investment-canada-act-review-of-cleveland-cliffs-acquisition-of-stelco.html), including commitments to maintain at least the same number of unionized employees and the vast majority of non-unionized employees who were there when the transaction was announced. Whether the current idling breaches those undertakings has not been established. Ottawa says it [intends to enforce the commitments](https://www.reuters.com/world/canada-will-do-all-it-can-ensure-cleveland-cliffs-meets-obligations-carney-says-2026-09-29/), while Stelco says some affected workers may be offered jobs at Lake Erie Works and that overall Canadian steel tonnage will remain stable. The episode cuts through Canadian chest-thumping. A deeply integrated economy gives both sides leverage and both sides vulnerabilities. Workers in Hamilton are living with that reality now. The rowboat can take on water too. ## Leverage is useful. Weaponizing it is not. One possible conclusion would be to treat every dependency as something Canada should threaten to shut off. That would carry its own costs. Contracts matter. Treaties matter. Canadian producers need customers. American buyers can invest in alternatives. Demonstrating that a dependency will be exploited whenever relations deteriorate gives the other side a powerful reason to eliminate it. Dependencies also change. Mines open. Smelters close or get built. Refineries reconfigure. Suppliers diversify. New infrastructure creates new routes. Canada’s leverage comes from being useful, reliable and difficult to replace quickly — not from pretending the larger economy has nowhere else to go. ## More exits, not a divorce Global Affairs Canada says exports to the United States fell 3.7 per cent in 2025 while exports to non-U.S. markets rose 11.1 per cent. Non-U.S. destinations reached [32.8 per cent of Canadian exports](https://international.canada.ca/en/global-affairs/corporate/reports/chief-economist/state-trade/2026), the highest share in more than four decades. Some of that shift reflects commodity prices and unusually strong gold exports. Some of it is new physical capacity. [Nasty Canuck has just reported on LNG Canada’s Phase 2](https://www.nastycanuck.ca/lng-canada-phase-2-asia-route/), which will double capacity on an operating Pacific export corridor. We have also followed [Canpotex’s C$500-million modernization of its Neptune terminal](https://www.nastycanuck.ca/canpotex-500-million-neptune-potash-terminal/), another route for Canadian production to reach overseas customers. Neither project replaces the United States — nor is that the point. Diversification is not divorce. It is the slow work of adding routes, customers and options so that one relationship — however large — is less likely to become a single point of failure. The aircraft-carrier metaphor works as a warning to Canada: national pride does not change economic scale. Canada remains the smaller economy and the more exposed partner. But scale does not erase logistics. The two countries have spent generations building a system in which Canadian resources feed American industry while American capital, customers and technology feed Canadian industry. Pull hard enough on either side and both feel it. Canada is the smaller boat, but that does not make it disposable or the larger vessel self-sufficient. **The aircraft carrier may be bigger, but it’s better to be a rowboat upstream with the shovel.**
