Canada's critical minerals sector has the potential to reshape supply chains, but capital investment gaps may limit its strategic potential. As global supply chains face pressure to reduce reliance on single suppliers, Canada's geological advantages position it as a strategic partner for diversifying mineral procurement networks in Western countries. However, the Royal Bank of Canada points out that insufficient capital investment could hinder Canada's ability to meet this demand. If Canada can mobilize enough investment, it could provide alternative procurement routes for Western manufacturers, reducing supply chain vulnerabilities while supporting regional economic development. Critical minerals are essential inputs in manufacturing processes, with copper, lithium, cobalt, and nickel being particularly noteworthy due to their applications across multiple supply chains. The International Energy Agency estimates that global investment in critical minerals could reach $500 billion to $600 billion by 2040. Despite Canada's favorable geological conditions, it currently accounts for only 2% of the global supply of six core metals. The Canadian government suggests that this share could grow to 14% by 2040, contingent on its ability to fund projects and prioritize supply chain development. Quebec and Ontario's high-grade lithium belts and graphite deposits can support battery manufacturing supply chains, while Manitoba's nickel resources and British Columbia's copper reserves offer potential alternatives to existing procurement routes. However, undercapitalization may impede these resources from entering commercial supply chains. Canadian companies need to deploy significant capital across the value chain to establish viable supply routes. The Canada Growth Fund has made three investments in minerals, but additional capital is needed to achieve meaningful supply chain capabilities. By deepening supply chain integration with the United States, Canada can address its capital needs, but maintaining supply chain resilience requires diversification beyond bilateral arrangements.
