Canada Plots Up to Ten New Reactors, Adding Pressure to Uranium Supply Outlook
Canada has outlined plans to build as many as ten new nuclear reactors, the latest major western nation to announce a sizeable expansion of atomic capacity that analysts say is already straining the long-term uranium supply picture.3
The scale of the Canadian ambition matters for commodity markets because it arrives as Goldman Sachs has revised its uranium demand model upward, adding small modular reactors for the first time. Goldman analyst Brian Lee's latest Nuclear Nuggets tracker forecasts roughly 46 gigawatts of SMR deployments by 2045, lifting Goldman's nuclear generation forecast by about 6% and creating an additional 62 million pounds of uranium demand — a 17% increase over prior long-term estimates.4,5
Uranium spot prices were already holding in the mid-to-high $80s per pound before Canada's announcement, with term pricing near $90 per pound according to Goldman's tracker. Spot has not moved sharply higher on the news in early trading Wednesday (2026-06-24), with the uranium ETF URA off 2.6% at $45.58, a move traders attributed to broader equity-market risk aversion rather than any shift in the fundamental supply-demand balance.5
Canada's move is part of a pattern accelerating across multiple jurisdictions simultaneously. The European Commission on Tuesday (2026-05-19) opened an investigation into France's plan to subsidise six new reactors with a combined capacity of 10 gigawatts at an estimated cost of EUR 73 billion. The probe will examine whether France's proposed support scheme distorts the single market, a process that could take years to resolve and that leaves the French program in a state of regulatory uncertainty even as Ottawa moves ahead.1
In the United States, the Nuclear Regulatory Commission approved subsequent license renewals for St Lucie Units 1 and 2 and for the 759-megawatt Robinson Unit 2 in South Carolina, extending operations to 2050 under what officials described as accelerated federal timelines. The US approach — extending existing assets rather than building new ones — contrasts with Canada's greenfield ambitions.3
Canada does have operational experience to draw on. Bruce Power signed a memorandum of understanding with SaskPower in April (2026-04-16) to share expertise in large-scale reactor development, a signal that at least some of the planned expansion would involve proven CANDU or CANDU-adjacent technology rather than unproven SMR designs.3
The gap between announced plans and delivered megawatts remains the central credibility problem for the nuclear renaissance. As the Economist noted in a recent review of the sector, the only countries connecting reactors to the grid with any regularity have been China and Russia. Between 2008 and 2021, Rosatom started and completed ten reactors at five power plants inside Russia; China has been building at a comparable clip using multiple designs. Western programmes have been slower, more expensive, and subject to regulatory and cost overruns that the industry is only beginning to address with modular construction approaches.2
Goldman's decision to formally include SMRs in its uranium demand model signals growing institutional conviction that at least some of the announced wave will materialise, even if on delayed schedules. The 62 million pounds of additional demand the bank now projects by 2045 would be consequential in a market where new mine supply has not kept pace with existing demand, let alone a buildout of this magnitude.
Term prices near $90 per pound reflect this expectation to some degree, but spot in the mid-to-high $80s also reflects uncertainty about which of the many announced programs will clear financing, permitting, and construction hurdles. Canada's announcement is politically credible given its established industry and federal support, but the specific reactor mix — between large conventional units, SMRs, and potential refurbishments — and the procurement timeline have yet to be set out in binding terms.
For uranium traders, the more immediate signal to track is whether Canada's announcement prompts additional offtake negotiations with the major uranium producers, Cameco in particular, and whether term prices push materially above $90 per pound in the months ahead. A repricing at the long end of the uranium forward curve would confirm that the market is treating the western buildout as a hard supply commitment rather than a pipeline of aspirations.
