The United States cannot break China's grip on critical mineral supply chains without Canada. That is the central takeaway from mining industry discussions across North America, where policymakers, miners and manufacturers are reassessing how to build a resilient mineral supply chain that reduces dependence on Chinese-controlled processing and refining. Canada is uniquely positioned as a near-shore, democratic alternative with established mining infrastructure, vast untapped mineral endowment and a stable regulatory framework. The question is no longer whether US-Canada minerals cooperation matters, but how quickly both nations can align policy, capital and permitting to deliver results.

China currently dominates multiple stages of the critical minerals value chain, from refining and separation to downstream manufacturing of battery components and permanent magnets. While Canada and the US hold substantial mineral reserves, much of the ore mined in North America has historically been shipped overseas for processing. This structural gap leaves both economies exposed to supply disruption, trade restrictions and price volatility. Closing this processing gap is the core challenge — and Canada's role is indispensable.

Canada's mineral endowment spans lithium, nickel, cobalt, copper, rare earth elements and potash, across provinces from Quebec to British Columbia and the Ring of Fire in Ontario. Many of these deposits are located near existing rail, port and power infrastructure, reducing development costs relative to frontier jurisdictions. The US benefits from proximity: mineral shipments from Canadian mines reach American processing facilities and manufacturing hubs within days, not weeks. This near-shore advantage is a defining strategic asset that no other allied nation can match at scale.

The political momentum behind this agenda is substantial. Both US and Canadian governments have launched critical minerals strategies, designated priority mineral lists and created financing mechanisms to support mine and processing projects. The US Defense Production Act has funded domestic rare earth separation and lithium refining capacity, while Canada's Critical Minerals Infrastructure Fund supports access road and power development for remote projects. Yet policy declarations alone are insufficient. Mining projects in North America routinely take seven to ten years from discovery to production — timelines that are incompatible with the urgency of the energy transition and supply chain security goals.

Permitting remains the single largest bottleneck. Environmental assessment processes, Indigenous consultation requirements and inter-agency coordination have, in many cases, extended project timelines well beyond what commercial investors can tolerate. Streamlining permitting without compromising environmental standards is essential. Canada and the US must align regulatory timelines, create parallel assessment pathways and build Indigenous partnership frameworks that deliver social licence at the speed the market requires.

Capital is also flowing. North American pension funds, sovereign wealth vehicles and strategic investors are increasingly evaluating critical mineral projects as a distinct asset class. However, investors require predictable policy, clear offtake signals and reasonable return profiles. US government purchase commitments — whether for defense, grid modernization or EV adoption — can serve as anchor demand that de-risks Canadian mine development.

For mining service providers, equipment manufacturers and engineering firms, the US-Canada critical minerals corridor represents a significant multi-year opportunity. Every new mine, processing plant and separation facility creates demand for drilling, materials handling, pumps, filtration, environmental monitoring and construction services. Companies positioned to serve this integrated North American market will be well placed as project development accelerates.

The alternative to deep US-Canada cooperation is continued reliance on Chinese processing capacity — an outcome that both nations' industrial strategies explicitly seek to avoid. Time is not neutral: every year of delayed development strengthens the entrenched cost and scale advantages that Chinese refiners have built over two decades.

Breaking China's grip on critical mineral supply chains is not achievable by the United States acting alone. Canada's resource endowment, infrastructure proximity and shared regulatory values make it the indispensable partner. Successful US-Canada critical minerals cooperation requires parallel progress on exploration investment, domestic processing capacity, permitting reform and anchored demand. The mining industry has the geology; what remains is the policy alignment and capital deployment to convert mineral potential into secure, integrated North American supply.
