Canada Launches Nuclear Energy Strategy, Targeting Up to 10 New Reactors by 2040

Canada's federal government launched its Nuclear Energy Strategy on 22 June 2026, setting a concrete build target of up to 10 new reactors over the next 15 years, with at least one sited outside Ontario.

The headline milestone is construction start. Reuters reports the strategy calls for two reactors to be under construction by 2035, with the broader fleet of up to 10 online by 2040. That phased cadence — spades in the ground within a decade, full fleet within fifteen years — follows a pattern familiar from South Korea's build programs, where construction sequencing across sites allowed supply chains and regulatory workflows to mature in parallel.

What the Strategy Contains

The document arrives after Natural Resources Canada signalled the strategy's development in April 2026, having committed to releasing it before year-end. The June launch is therefore on schedule, though the policy substance now on the table is what the industry has been waiting to assess.

The geographic diversification clause is notable. Ontario's CANDU fleet and the Darlington new-build work have long dominated the Canadian nuclear conversation. Explicitly requiring at least one reactor outside Ontario signals an intent to distribute grid and economic benefit — and regulatory and community engagement burden — across provinces. Which provinces are in scope is not yet confirmed in publicly available detail.

Canada brings real upstream weight to this ambition. The country produced approximately 24 percent of global uranium output in 2024, making it one of the world's two or three dominant suppliers. Domestic fuel supply is not a strategic vulnerability for Canada in the way it is for countries that must contract long-term with Kazakhstan or Russia. That supply-chain insulation is a genuine structural advantage as reactor procurement discussions begin.

The domestic industry base is already substantial. The nuclear sector accounts for roughly 89,000 jobs and contributes an estimated C$22 billion to the Canadian economy, according to Natural Resources Canada briefing materials. A build program of this scale — up to 10 reactors — would stress that existing workforce and supply chain, which raises practical questions about whether Canada can source sufficient skilled trades, nuclear-grade component manufacturing, and regulatory capacity domestically, or whether procurement will lean on international partners.

The Broader Context

The timing fits a global pattern. Multiple governments across Europe, Asia, and North America have moved or are moving to extend existing fleets and greenlight new capacity, driven by decarbonisation targets, energy security calculations sharpened by recent geopolitical disruption, and rising electricity demand from data centre buildout and industrial electrification. Canada's strategy is a policy-level formalisation of an industry direction that has been consolidating for several years.

Worth flagging here is the gap between announced intent and executed construction. Canada's nuclear build history is complicated. The CANDU program produced a capable reactor design but several export contracts ran into significant cost overruns and schedule extensions. More recently, the global small modular reactor development pipeline — in which Canadian vendors including Terrestrial Energy and Moltex are active — has moved slower than early timelines suggested. Whether the new strategy leans on large conventional reactor designs, SMRs, or some combination of both is a material detail that the published summaries do not yet resolve.

The 2035 construction-start target for the first two reactors is roughly nine years out. For nuclear, that is not a long runway — regulatory review, site preparation, and supply chain contracting for a gigawatt-scale plant typically consume several years before first concrete. The credibility of the 2035 milestone will depend heavily on what site selection, environmental assessment, and reactor technology decisions are made in the next 24 to 36 months.

Natural Resources Canada's role as the strategy owner places implementation coordination within an energy and resources ministry rather than a dedicated nuclear agency. How that interacts with the Canadian Nuclear Safety Commission's independent licensing process — and whether any regulatory streamlining is contemplated — will be among the first questions the industry puts to government as engagement on the strategy opens.

The launch of the strategy is a concrete policy step. What it enables, practically, turns on execution decisions still ahead.
