# Does Canada's New Nuclear Strategy Signal a Generational Build Program?

Canada's federal government announced on June 22, 2026 a national Nuclear Energy Strategy targeting up to 10 new large-scale reactors by 2040 — the most ambitious domestic nuclear build program the country has articulated in decades. The strategy sets hard interim milestones: two reactors under construction by 2035, five additional reactors planned or under development by 2040, and at least one reactor operational or under construction outside Ontario by 2035. A microreactor demonstration is also targeted for 2035, with deployment to a rural community by the late 2030s. The announcement was made at a news conference in Newmarket, Ontario, attended by federal Energy and Natural Resources Minister Tim Hodgson, Ontario Minister of Energy and Mines Stephen Lecce, and other federal, provincial, and industry officials. The strategy rests on four pillars: new domestic nuclear builds, maintaining Canada's position as a top nuclear supplier and exporter, expanding uranium production, and advancing fission and fusion innovation. Separately, ongoing projects at Darlington and [Ontario Power Generation](https://smrintel.com/companies/opg) and Bruce Power are already running in parallel to this strategic framework.

## What the Strategy Actually Commits To

The headline figure — up to 10 reactors — is a ceiling, not a guarantee. The binding milestones embedded in the strategy are considerably more specific, and reading them carefully matters for anyone pricing Canadian nuclear risk.

**Domestic build targets:**
- Two reactors under construction by 2035
- Five additional reactors planned or under development by 2040
- At least one reactor deployment outside Ontario operational or under construction by 2035
- A microreactor demonstrated by 2035, deployed to a rural community by the late 2030s

One of the strategy's critical technical commitments is ensuring a "modernized, cost-competitive" design of Canada's CANDU pressurized heavy water reactor is in place by 2030. This signals that the primary vehicle for the large-scale reactor program remains a domestically developed design — not a foreign-vendor light water reactor import. That's a significant industrial policy choice with direct implications for the [Canadian Nuclear Safety Commission](https://smrintel.com/glossary/cnsc) licensing pipeline and domestic supply chain investment.

The strategy also explicitly acknowledges three enabling conditions that do not yet exist at the required scale: private financing attraction, increased Indigenous communities' participation, and a streamlined regulatory framework. These are frank admissions, not boilerplate. Any utility executive or energy investor modelling a Canadian build program should treat all three as schedule-risk line items.

## The Export and Uranium Dimensions

The strategy's second and third pillars carry significant commercial weight beyond Canada's borders.

On CANDU exports, the strategy sets out specific targets: secure CANDU reactor agreements in at least four new countries and engage an additional six to ten "new nuclear entrant markets" in discussions by 2040. Canada also aims to capture "significant Canadian supply chain participation" in at least five international non-CANDU reactor projects — acknowledging that not every market will choose a CANDU design while still positioning Canadian firms for a role in the global build wave.

Currently, CANDU reactor technology powers 26 reactors across six countries: 17 domestically and nine across South Korea, China, Romania, Argentina, and India, according to the Canadian government's own release figures. Ongoing CANDU projects in Romania and China are cited as priority successes to be secured under the new strategy.

The uranium dimension is equally concrete. Canada produced approximately 24 percent of the world's uranium in 2024, exporting roughly 90 percent of that output. The strategy calls for doubling uranium exports between 2024 and 2035, supported by new mining production expected to come online by 2035. [Cameco Corporation](https://smrintel.com/companies/cameco) and developers like [NexGen Energy Ltd](https://smrintel.com/companies/nexgen-energy) and [Denison Mines Corp](https://smrintel.com/companies/denison-mines) stand to benefit directly from a policy framework that explicitly targets expanded extraction capacity — though the strategy document itself does not name specific mining projects.

Fuel supply chain security is addressed through a separate objective: strengthening and securing fuel supply chains for all Canadian reactors by 2032.

## The Geopolitical Subtext

Minister Lecce's statement at the June 22 event was notable for its directness: "Ninety-four percent of all nuclear reactors in the last decade were built by the Chinese or the Russians." That figure, cited in the ANS source, frames the entire strategy as a Western industrial and geopolitical response to the dominance of [Rosatom State Nuclear Energy Corporation](https://smrintel.com/companies/rosatom) and [China National Nuclear Corporation](https://smrintel.com/companies/cnnc) in global reactor exports. The phrase "Team Canada approach" — used in the strategy document — signals Ottawa's intent to coordinate government, utilities, and private industry into a single export-capable bloc, analogous to how France, South Korea ([Korea Hydro & Nuclear Power](https://smrintel.com/companies/khnp)), and the United States have at various times organized their nuclear export capabilities.

Whether Canada can execute this vision depends heavily on the CANDU modernization timeline. A competitive, licensable design available by 2030 would put Canada in the market in time for the next wave of new-entrant country decisions — many of which are currently in early feasibility or vendor selection stages.

## Waste Management: The Constraint That Could Set the Schedule

The strategy explicitly links radioactive waste management pace to the rate of new reactor deployment — a constraint that rarely appears this prominently in national nuclear strategy documents. Specifically, the strategy calls on proponents to "develop long-term plans for low- and intermediate-level waste management and disposal solutions under the Integrated Strategy for Radioactive Waste." This is a direct acknowledgment that Canada's waste framework needs to scale in parallel with its build ambitions, not lag behind them. For utilities and project developers, this is both a risk signal and a potential procurement opportunity.

## Industry Trajectory: What This Means Beyond Canada

A national strategy explicitly targeting 10 large reactors by 2040 from a G7 country with an established nuclear supply chain, existing reactor fleet, and dominant uranium production position materially changes the global demand picture. The strategy adds pressure on [Westinghouse Electric Company](https://smrintel.com/companies/westinghouse) and other vendors competing in new-entrant markets to engage Canadian supply chain partnerships — or risk ceding ground to a coordinated CANDU export push. For uranium market analysts, a Canadian commitment to double exports by 2035 provides a concrete demand signal against which [Cameco Corporation](https://smrintel.com/companies/cameco) and junior miners can model investment cases. The [First of a Kind (FOAK)](https://smrintel.com/glossary/foak) cost risk embedded in the CANDU modernization program remains the single largest execution uncertainty, but the political alignment across federal and provincial governments visible at the June 22 event is a genuine change from Canada's historically fragmented approach to nuclear expansion.
