Justin Trudeau did discuss the electricity and infrastructure needed to power artificial intelligence at the February 10–11, 2025 Paris AI Action Summit. But the official Canadian record does not show him declaring nuclear energy to be “the solution.” Canada’s account refers to clean and reliable energy, stronger grids and responsible AI growth. The explicit argument that nuclear power could attract AI data centres came from French President Emmanuel Macron. The distinction matters: the summit did not choose one technology, announce a Canadian reactor programme for AI or make nuclear power a binding policy.
What Trudeau actually said
According to the Canadian prime minister’s post-summit account, Trudeau argued that AI’s expansion requires access to clean and reliable energy. He also highlighted using AI to make electricity grids more reliable and treated energy and infrastructure as central to AI investment. He chaired or participated in a roundtable devoted to AI’s infrastructure and energy requirements.
That wording is broader than nuclear power. The government’s February 12 readout does not say Trudeau announced nuclear energy as Canada’s AI strategy. The government’s pre-trip announcement likewise described a discussion about powering the next generation of AI, rather than a nuclear-specific commitment.
Where the nuclear argument came from
Macron made the more direct nuclear case. In an Élysée Palace transcript, he presented France’s nuclear-heavy electricity system as an advantage for hosting data centres and attracting AI investment. France’s relatively low-carbon, continuously available generation was part of the country’s pitch to technology companies.
#1 Best Overall
That can easily become compressed in headlines into “Trudeau says nuclear energy is a solution for AI,” even though the available primary records support a different attribution:
| Speaker or document | Verified position |
|---|---|
| Justin Trudeau | AI needs clean, reliable energy; grids and infrastructure must keep pace. |
| Emmanuel Macron | France’s nuclear-based electricity system can help power AI and attract data centres. |
| Paris summit declaration | AI’s energy and environmental effects should be measured and addressed through sustainable infrastructure and innovation. |
What the summit declaration committed to
The joint statement, published by Canada on February 11, 2025, recognized AI’s environmental and energy impacts. It encouraged investment in sustainable AI systems, including hardware, models and infrastructure; supported international discussion of AI and the environment; welcomed an International Energy Agency observatory on AI’s energy impact; and highlighted more energy-efficient AI innovation.
Rank #2
It did not require countries to build reactors, name nuclear power as the preferred source for data centres, establish a nuclear-generation target or announce a Canadian AI-nuclear project. The meeting broadened AI policy beyond safety and governance to include electricity, sustainability, labour and economic development, but it did not settle the technology question.
Why electricity has become an AI policy issue
Training and running large models takes place in data centres that need substantial, dependable electricity. Their operators require firm grid connections, cooling capacity and predictable power quality. A shortage of generation is only one possible bottleneck: transmission, substations, permitting and the ability to connect a large new load can matter just as much.
Rank #3
Nuclear plants can provide low-carbon generation around the clock, which is attractive for facilities operating continuously. Existing nuclear sites may also have industrial expertise and grid connections. But “available generation” does not automatically mean a data centre can receive dedicated power; commercial contracts, transmission capacity and interconnection work are still required.
Is nuclear a practical solution?
Nuclear is one possible source of firm, lower-carbon electricity, not an immediate or universal answer.
Rank #4
- Timing and finance: New conventional reactors can take many years to license, finance, build and connect, with substantial construction and cost-overrun risk.
- Location: Existing plants may be far from proposed data-centre clusters, requiring transmission upgrades.
- Regulation and public acceptance: Licensing, cooling-water needs, waste management, decommissioning and local consent remain material issues.
- Small modular reactors: SMRs are promising in policy discussions, but many projects remain subject to technology, licensing, financing and deployment uncertainty rather than being immediately available at commercial scale.
- Environmental qualification: Nuclear has low operational carbon emissions, but fuel production, construction, thermal discharges, waste and decommissioning still have impacts.
Other options can complement or compete with nuclear: Canada’s hydroelectricity, wind and solar paired with storage or firming resources, natural gas with or without carbon capture, expanded transmission, demand response, load shifting and more efficient chips, models and cooling systems. Data-centre operators can also procure clean electricity through contracts or locate near existing generation. The relevant policy question is usually a portfolio and grid-design question, not nuclear versus renewables in isolation.

What Canada was promoting
Trudeau used the summit to present Canada as an AI research and investment partner with substantial clean-electricity resources and a responsible-governance position. During the visit he met executives and leaders from Anthropic, AMD, OVHCloud, Hugging Face and Arm, according to the Canadian government readout. The post-summit account says he met more than a dozen CEOs and AI leaders.
Best Value
That pitch connects Canada’s AI ecosystem with its hydro, nuclear and renewable capabilities, but it should not be mistaken for a funded or approved reactor plan dedicated to AI data centres. No such announcement appears in the official Canadian materials cited here.
How to read the headline
The headline is best understood as a conflation or compressed paraphrase. Trudeau’s verified message was that AI growth needs clean, reliable energy and better energy infrastructure. Macron made the explicit argument that nuclear-heavy French electricity could support AI data-centre growth. The summit declaration endorsed sustainable AI infrastructure and monitoring of energy impacts, without prescribing nuclear power.
So the accurate claim is narrower: Trudeau linked AI’s future to clean, reliable electricity at the Paris summit; the nuclear-specific pitch came principally from Macron. Calling nuclear “the” solution, claiming that Canada announced reactors for AI or suggesting that the summit selected nuclear power goes beyond the evidence.
