AI’s Power Hunger Sparks Nuclear Gamble

Canada’s fast-track nuclear push promises cheap, steady power for industry and homes—but the plan’s speed, waste gap, and costs could test public trust.

Story Snapshot

Ottawa outlines up to 10 new large reactors by 2040, plus a first-of-its-kind small modular reactor.

Critics warn of long build times, higher costs, and unresolved waste policy.

Canada’s Build-Out: What Is Actually On the Books

Government plans say Canada could add up to 10 large reactors, with two under construction by 2035 and five more planned by 2040, if approvals and financing hold ^[6]. Ontario directed Ontario Power Generation to study new generation at Wesleyville, a site that could host about 10 gigawatts for around 10 million homes if fully developed ^[1]. Ottawa’s strategy sets the direction, but many steps remain. Signed contracts and full environmental reviews for the full fleet are not all in hand yet ^[6].

Officials highlight a flagship small modular reactor at Darlington that would power about 300,000 homes, making Canada the first Group of Seven country to deploy this type at scale, according to public remarks by the federal energy minister ^[5]. The federal plan also includes ten-year funding of about 2.2 billion dollars to speed projects and innovation, which supporters say can help hold schedules and costs ^[5]. Advocates frame this as a hedge against spikes in gas prices and grid stress from new factories and data centers.

Fuel Supply: Uranium as Strategic Leverage

Analysts note Canada holds the third-largest uranium resources and is raising output to backstop Western supply chains ^[4]. The federal government cleared the first new uranium mines in Saskatchewan in over a decade, including the Rook One project, which officials said could meet roughly one-fifth of world uranium demand at full scale ^[5]. Supporters say this lowers reliance on rivals and improves price stability for fuel. That could matter for both Canada and the United States as they expand nuclear fleets.

Ontario’s study at Wesleyville and federal moves to expand uranium output tie energy and security together. Backers argue domestic fuel plus new reactors can cut emissions and keep power on during extreme weather. They also see a chance to export services and fuel. But energy security also depends on enrichment and long-term waste solutions. Critics warn that gaps in these areas could slow or derail growth if not fixed early in the timeline.

Jobs, Costs, and Timelines: Promise Meets Past Experience

Industry boosters say nuclear already supplies about fifteen percent of Canada’s power and could double sector jobs from about ninety thousand to more than one hundred eighty thousand with new builds and refurbishments ^[3]. They argue steady baseload power will lower bills over time by reducing price spikes. Yet history shows many nuclear projects run long and over budget. Environmental groups say new plants often take a decade or more and need large subsidies that could fund faster options ^[11].

Small modular reactors are marketed as cheaper and easier to build, but Canada has not released an audited, apples-to-apples cost review that compares them to large reactors or renewables for this program. The Darlington unit will test that claim in the real world ^[5]. Supporters point to rising nuclear projections by global agencies, while skeptics cite reports of flat builds outside Asia and warn that pledges often outpace delivery. Both trends can be true at once, depending on policy follow-through.

Waste and Public Trust: The Deciding Factor

Long-term waste policy remains the hardest political knot. Canada’s strategy backs “world-class” management, but the record lacks a single, licensed, and operating deep repository sized for the new fleet’s waste today ^[6]. In the United States, ongoing court fights and site limits show how waste can stall momentum even when new plants are proposed ^[15]. Without clear, binding milestones for storage and disposal, the public may doubt promises on safety and cost control.

For many readers across the spectrum, this story touches the same nerve: promises made, then delayed. Conservatives see risk in rising power costs, weak grids, and imports from rivals. Liberals see risk in waste, safety, and subsidies that crowd out social needs. Canada’s plan can ease both sets of fears only if leaders show real contracts, real budgets, real timelines, and a real waste path. The test is delivery, not press events and targets.

What To Watch Next

Watch for final environmental approvals, signed construction deals, and grid integration plans for projects beyond the first two units ^[6]. Track uranium mining ramp-ups, enrichment steps, and any moves toward a licensed deep repository sized to the 2040 build outlook. Ask for an audited cost study comparing small modular reactors, large reactors, and renewables. If those pieces line up in public view, confidence will rise. If not, Canada’s big bet may stall under its own weight.
