A Nuclear Wish List Ten Reactors Long
Canada is thinking big when it comes to keeping the lights on. As part of a sweeping new nuclear strategy, the federal government has floated building as many as 10 new nuclear power plants across the country over the coming decades. The plan is meant to help Canada meet growing electricity demand while sticking to its climate commitments, since nuclear power generates virtually no greenhouse gas emissions once a plant is up and running.
But there's a catch that's bigger than the reactors themselves: money. Building nuclear plants is notoriously expensive, with costs that can balloon well past initial estimates and timelines that stretch over a decade or more before a single watt of power gets sold. Governments alone can't easily absorb that kind of financial risk, especially when budgets are already stretched thin by housing, healthcare, and infrastructure needs.
Enter the Pension Funds
That's where Canada's massive pension funds come in. Institutions like the Canada Pension Plan Investment Board and others manage hundreds of billions of dollars in assets on behalf of Canadian workers and retirees, and they're constantly looking for stable, long-term investments that can deliver reliable returns for decades. Nuclear infrastructure, in theory, fits that profile — it's the kind of slow-and-steady asset that pairs well with pension liabilities that also stretch far into the future.
The catch is that pension fund managers have a fiduciary duty to protect the retirement savings they oversee, which means they tend to be risk-averse when it comes to projects with a track record of cost overruns and delays. Nuclear builds around the world, including in Canada, have a long history of both. For pension funds to sign on, the federal government will likely need to find ways to shoulder more of the early-stage risk itself, whether through loan guarantees, cost-overrun protections, or other financial backstops that make the investment case more palatable.
Why This Matters for Ontario
Ontario already leans heavily on nuclear power, which supplies roughly half the province's electricity through stations like Darlington, Bruce, and Pickering. Any new wave of nuclear construction under this federal strategy would likely include Ontario sites, given the province's existing expertise, supply chains, and regulatory experience with the technology. Ontario Power Generation has also been at the forefront of Canada's next generation of nuclear technology, including small modular reactors currently under construction at the Darlington site.
That means the outcome of these pension fund negotiations could directly shape how much new nuclear capacity ends up built in Ontario communities, and how quickly. If de-risking measures succeed in attracting private capital, Ontario could see faster movement on new projects. If they don't, the province may be left waiting on federal and provincial public financing alone to move the needle, which could mean longer timelines for expanding non-emitting power generation.
What Comes Next
For now, the strategy remains more vision than blueprint, with the hard work of structuring financing deals still ahead. How the federal government balances protecting pension holders' savings with the urgent need for new electricity generation will be one of the more consequential economic stories to watch as Canada tries to modernize its energy grid over the next decade.
