The metals and rare earths behind batteries, electronics and weapons — where Canada is rich in the ground but exposed in the supply chain.
Critical minerals are inputs — lithium, nickel, cobalt, rare earths and more — that are essential to modern technology and defence and whose supply is concentrated or at risk. Canada has large deposits but limited processing capacity.
The vulnerability isn't only extraction; it's that refining and supply chains are dominated by a few countries. Owning the rock isn't the same as controlling the supply.
Critical minerals sit at the crossroads of economy, technology and security: they power the energy transition and military hardware alike. Dependence on potentially hostile suppliers is a strategic risk allies are actively trying to reduce.
Building domestic processing and allied supply chains is slow and capital-heavy, and extraction collides with environmental protection and Indigenous consent. There's no fast, clean lever here.
Resource wealth has been strategic for over a century — what counts as “critical” keeps changing.
From the late 19th century, the Sudbury basin made Canada a global nickel power; in WWII its nickel was vital to the Allied war effort. Resource wealth has long been strategic.
What's “critical” is defined by the era's technology — and by who controls the supply.
During and after the Cold War, governments treated certain minerals as strategic, building stockpiles and screening foreign control of key resources.
Security thinking about minerals is old; the list of what matters is what changes.
As demand for batteries and electronics surged, supply concentration in a few countries pushed Canada and allies to launch critical-minerals strategies and tighten foreign-investment screening on key assets.
Having the deposits isn't enough. Without processing and trusted partners, the rock stays leverage for someone else.
Where no public, verifiable figure exists, BEAVER.WATCH describes the situation in qualitative terms rather than invented numbers. The one numeric benchmark used elsewhere on the site — the 2%-of-GDP defence target — is a public NATO goal.
The simulation lets you choose how far to secure the chain — and who pays.
Refine at home, build reserves, partner with allies. Exposure drops.
COST: CAPITAL-HEAVY · LAND-USE CONFLICTSCoordinate sourcing with trusted partners. Faster than going solo.
COST: STILL DEPENDENT, JUST ON FRIENDSBlock hostile control of key assets. Targeted, defensive.
COST: INVESTMENT FRICTIONThe minerals reality: Canada is rich in the ground and poor in the supply chain. Sovereignty over resources means controlling not just the mine, but the refinery and the route to market.
