Introduction
The global copper market has entered a structural supply deficit that began in 2025 and is projected to widen significantly through 2040 and beyond. Demand is surging due to electrification, AI/data centres, grid expansion, and defence spending. This trend occurs while mine growth remains constrained by declining ore grades, long development timelines, and operational disruptions.
In North America, the United States faces significant challenges arising from slow permitting and minimal new development, making it heavily reliant on Canadian imports (95-99 % of copper ore and concentrate). Canada, though it is a reliable supplier with steady output (approximately 2 % of global production), cannot fully offset the global shortfall or rapidly expand due to its own lengthy project timelines. Further, in 2025-26, international disruptions in top producers Chile, Indonesia, and Peru have removed hundreds of thousands of tonnes from the market, tightening global availability and raising North American supply pressures.
Copper Production and the Widening Supply Gap in Canada and the United States
Canada produced 514,582 tonnes of copper in 2024, ranking 12th globally, with British Columbia as a key hub. Therefore, it remains indispensable to the U.S. However, due to aging mines, output has trended lower over the past decade. Further, new projects historically take decades amid rigorous reviews, as detailed in the Oregon Group’s analysis of Canada’s role in global copper supply chains. [1]
The United States’ domestic production in recent decades remains limited with virtually no new mines on federal land, despite substantial reserves. Heavy import reliance persists, exacerbated by U.S. stockpiling in 2025 amid tariff concerns, which has tightened global copper availability. The regional gap widens as North American demand surges from AI, EV’s, and infrastructure outpacing modest supply growth – even with Canada’s stable contribution.
Permit Delays as a Key Constraint in North America
Permit delays create bottlenecks that severely limit new capacity additions. In the U.S., timelines from discovery to production average approximately 29 years, with permitting alone taking 7 – 10 years under NEPA, environmental reviews, tribal consultations, and litigation. The Resolution Copper project (Rio Tinto/BHP joint venture in Arizona) underscores the issue: discovered in the 1990s, over $2 billion was invested but the project is still not in production in 2026. It could supply up to 25 % of U.S. copper demand but has experienced over 20 years in permit delays. It will likely not be in production until the 2030’s. [2]
In Canada, new mine development averages 16.8 years because of environmental assessments and community consultations. [2] However, reforms such as eliminating duplicate federal reviews aim to accelerate timelines. As noted in the Oregon Group’s report, high ESG standards enhance stability but slow down greenfield projects compared to faster jurisdictions. [1]
Impact of Disruptions in Chile, Indonesia, and Peru
Major copper producers faced severe disruptions in 2025 that affected 2026 supply. Chile, which provides approximately 24 % of global output, saw impacts from a nationwide power outage, a tunnel collapse at Codelco’s EI Teniente, declining grades, and infrastructure issues at Collahuasi and Los Bronces. These developments contributed to a tighter concentration in copper markets. [4] In 2025, Indonesia experienced a fatal mudslide at Freeport-McMoRan’s Grasberg (the world’s #2 mine), triggering a shutdown of the Block Cave section (70% of output) through to at least Q2 2026, with recovery delayed amid lower grades. [3] Peru dealt with protests leading to shutdowns (i.e. Hudbay’s Constancia in 2025), accidents at Antamina, and national output contraction due to social unrest. [4]
These incidents, alongside others such as DRC flooding at Kamoa-Kakula, removed substantial volumes, which drove record deficits, record prices, and volatility, as reported in J.P. Morgan’s analyses. [3] In consequence, North America experiences indirect affects through elevated global prices and import constraints, though Canada does provide a regional buffer.
Conclusion
The copper deficit is structural, stemming from chronic underinvestment, acute permitting delays, aging assets, and frequent disruptions in key jurisdictions. For Canada and the U.S., this increases import dependence, supports higher prices for producers, but poses risks to downstream industries critical for energy transition and growth. Accelerating permit reforms, boosting investments, and enhancing recycling are urgent priorities. Canada’s reliable supply role strengthens North American security, but global events underscore the need for faster and more diversified regional production of copper.
