Leading the Charge: Inside Canada’s Nuclear Transformation in 2025
The Dawn of Canada’s Nuclear Transformation
As we close the chapter on 2025, Canada’s nuclear power landscape has transformed remarkably. Previously a stable sector focused on legacy reactors, it has now evolved into a dynamic push for innovation and decarbonization. Consequently, 2025 will be remembered as the pivotal year of Canada’s nuclear transformation. Nuclear energy shifted decisively to the forefront of the nation’s clean energy strategy.
Canada’s Decisive Shift: From Stability to Strategic Expansion
A National Awakening
The narrative around nuclear energy in Canada changed significantly, marking a clear turn in Canada’s nuclear transformation. With nuclear already providing 15% of the country’s electricity, governments ramped up commitments to expand capacity. This drive was fueled by rising energy demands from electrification and data centers. Additionally, the need to meet net-zero goals by 2050 created further urgency. Industry leaders described this as a “new path emerges.” Notably, investments surpassed $60 billion in nuclear and related infrastructure.
As Tim Hodgson, Minister of Energy and Natural Resources, stated:
“Through a new Centre for Fusion Excellence, Canada and Ontario are taking another step forward to strengthen our nuclear energy sector.”
Major Projects and Regional Developments
Ontario: Darlington New Nuclear Project
A landmark achievement powering Canada’s nuclear transformation was the Darlington New Nuclear Project. In April 2025, the Canadian Nuclear Safety Commission (CNSC) issued a construction license for the first GE Hitachi BWRX-300 SMR in the G7. Construction began in May, targeting 2030 for the first unit. Furthermore, in October, governments committed $3 billion in equity funding. This is part of a $20.9 billion project for four units totaling 1,200 MWe. Meanwhile, Bruce Power advanced its Bruce C project. It submitted a description for up to 4,800 MWe of new capacity. Similarly, OPG initiated planning for up to 10,000 MWe at Wesleyville, with construction eyed for the 2030s.
Western Provinces: Nuclear as a Sovereignty Imperative
Saskatchewan emerged as a key player driving Canada’s nuclear transformation. It released an Energy Security Strategy in October, focusing on SMRs. Consequently, SaskPower narrowed sites to Estevan for four BWRX-300 units by the late 2030s. It also created SaskNuclear Inc. to lead development. Historically non-nuclear, Alberta signed a federal MoU in November to advance nuclear policy. Consultations wrapped up, though one impact assessment was suspended at the proponent’s request.
New Brunswick
New Brunswick also advanced its ARC-100 and Moltex SSR-W SMRs at Point Lepreau, targeting the early 2030s.
Technology Advancements: The SMR Revolution
Small Modular Reactors Take Center Stage
Canada’s SMR landscape exploded in 2025, with over a dozen designs under review. Key leaders included GE Hitachi’s BWRX-300 and Moltex SSR-W. The Darlington project notably positioned Canada as a global SMR pioneer, a cornerstone of the broader Canada’s nuclear transformation.
Advanced Fuel and Reactor Designs
Nuclear fuel advancements included progress on Accident Tolerant Fuels and HALEU for SMRs. Innovative designs like molten salt reactors gained traction. Furthermore, fusion emerged with the November launch of the Centre for Fusion Energy in Pickering. The CNSC also prioritized modern regulation for SMRs and fusion.
Financial Sector Commitment
Investments hit records, with green bonds including nuclear funding. A CNA study projected up to 50 GWe of new nuclear by 2050. This would meet 45% of baseload needs, underscoring the financial momentum of Canada’s nuclear transformation.
Safety and Sustainability: Non-Negotiable Priorities
Safety remained paramount, with IAEA reviews supporting Canada’s approach. The NWMO also selected a site for a deep geological repository. Advances in regional waste solutions aligned with sustainability goals.
New Market Entrants: Diversifying the Nuclear Landscape
Provinces like Alberta and Saskatchewan joined Ontario and New Brunswick. This signals a nationwide expansion central to this pivotal Canada’s nuclear transformation.
International Cooperation: Building Bridges
Canada continued the G7 Fusion Working Group and promoted exports. Bilateral partnerships accelerated expertise sharing.
Looking Ahead: Challenges and Opportunities
Persistent obstacles include financing, regulatory timelines, and public acceptance. However, 2025 showed nuclear’s essential role in carbon neutrality. Ultimately, stakeholders must focus on harmonization and engagement to sustain the progress of Canada’s nuclear transformation.
Conclusion: A Defining Year for Nuclear Power
In conclusion, 2025 will be remembered as the definitive year for Canada’s nuclear transformation. With major investments and SMR breakthroughs, the country positions nuclear as a cornerstone of clean energy. As we enter 2026, the industry faces unprecedented opportunity born from this transformation. Success requires commitment to safety, innovation, and collaboration. For energy professionals, the message is clear: nuclear power in Canada is thriving and leading the global transition. This rapid growth brings operational challenges—from specialized staffing to licensing support. To address these hurdles, many leading projects turn to partners like Accelerant Solutions, which delivers the integrated workforce strategies and advisory services needed to execute in this new nuclear landscape.
