Every F-35 fighter jet contains close to a tonne of rare-earth elements. A single electric-vehicle battery needs graphite, lithium, nickel, cobalt. A nuclear reactor runs on enriched uranium. None of these are optional for the country the United States is trying to remain, and for a growing share of them Washington has the same problem: it does not produce enough at home, and the processing that turns raw ore into usable material is dominated, often overwhelmingly, by China.
Which is where the map becomes interesting. Look just north. Canada sits on commercial deposits of nickel, cobalt, graphite, lithium, copper, uranium, tungsten, potash, aluminum and the rare earths — a large fraction of the very list the Pentagon and the Department of Energy lose sleep over. Two countries, one border, and a near-perfect fit between what one lacks and the other has. The surprising thing is not that they have noticed. It is how constructively they have decided to act on it.
Geology as alliance
For most of the last decade, critical minerals have been a story about vulnerability — a scramble to escape dependence on a single adversary that controls the midstream of the supply chain. Between Ottawa and Washington it has become something rarer: a shared project.
The framework is the Canada–US Joint Action Plan on Critical Minerals, which reads less like a trade agreement than a to-do list for two industrial states deciding to build together. It coordinates work across industry engagement, innovation, shared mapping of where the deposits actually are, and — the part that gives it teeth — defense supply chains. The point is not simply to trade rocks. It is to wire Canadian geology directly into American factories, weapons systems and reactors, so that a secure North American supply chain replaces an insecure trans-Pacific one.
The trade underneath is already enormous and old. Bilateral mineral trade ran to roughly 95.6 billion dollars as far back as 2020. Hundreds of Canadian mining companies operate across the border, holding tens of billions in assets on American soil. This is not a relationship being invented from scratch; it is one being formalized and pointed, deliberately, at a strategic goal both countries now share.
The money finally shows up
Diplomacy on minerals used to be all communiqué and no concrete. That is changing, and the numbers are the evidence.
Canada’s Critical Minerals Production Alliance is mobilizing around 18.5 billion dollars in projects, built across two rounds — one in late 2025 and a second in March 2026 that unlocked 12.1 billion dollars across a dozen allied partners. Sitting above it is a G7 declaration on securing critical-mineral supply chains, issued in June 2026, which turned the informal understanding among democracies into a stated common policy. Ottawa has gone further at home, designating certain minerals a national-security priority and standing up funds that let the government take equity stakes and sign offtake contracts — the state behaving less like a referee and more like an investor.
For the United States, the appeal is straightforward: a friendly, stable, resource-rich neighbour is the cheapest insurance policy available against a supply shock engineered in Beijing. For Canada, the logic is the mirror image — a guaranteed buyer with deep pockets for minerals that are worth far more processed than shipped raw. The interests line up almost perfectly, which is why this corner of the relationship keeps advancing while others stall.
The gap between a deal and a mine
Here is the sentence every honest account of Canadian critical minerals has to include: a mine is not a memorandum. And the distance between the two is where the optimism has to be tempered.
A new Canadian mine can take more than a decade to go from discovery to production, and Canadian permitting timelines are among the slowest in the G7. The alliances and action plans are real, but as of mid-2026 the pipeline is thick with signed intentions and thin on poured concrete and operating refineries. Announcing 18.5 billion dollars in “mobilized” projects is not the same as pouring the foundations of a processing plant that displaces Chinese supply.
There is also a quieter tension with the very partner Canada is courting. The United States is chasing the same minerals from the same allies, and its own subsidies make it an unusually attractive place to build the processing — which means Canada and America are sometimes competing for the investment even as they cooperate on the strategy. And Ottawa is trying to be two things at once: the champion of consent-based, environmentally responsible mining, and the advocate of building fast. Those ambitions do not automatically reconcile, and no action plan resolves them.
Still, set against the rest of the ledger, this is about as good as bilateral cooperation gets. The interests are aligned, the money is flowing, the strategic case is understood in both capitals, and the whole thing is aimed at a shared rival rather than at each other. If you want to know what a healthy Canada–US relationship looks like beneath the noise of the trade fight, look underground.
