Oil prices recently eased from six month highs after supply worries pushed energy back into the spotlight, and that keeps attention on where reliable baseload power might come from next. For Canadian investors, that question pulls nuclear power into focus as a potential long term backbone for electricity demand. This article walks through three stocks from a curated nuclear focused Canadian list that aim to tap into that theme.
The three stocks highlighted here offer a compelling starting point if you want exposure to uranium producers and nuclear-focused operators supplying reliable and sustainable power. However, if you want the absolute best, these 16 nuclear renaissance stocks are the cream of the crop.
AtkinsRéalis Group (TSX:ATRL)
Overview:AtkinsRéalis Group is a diversified engineering and project management firm whose dedicated Nuclear segment delivers reactor design, refurbishment, decommissioning and waste-management services across the full nuclear life cycle.
Operations:AtkinsRéalis generates about CA$2.6b from its Nuclear unit within a broader CA$10.4b engineering portfolio across UKI, USLA, Canada and AMEA segments.
Market Cap:CA$13.6b
AtkinsRéalis Group matters for this nuclear screen because it aims to supply the underlying engineering, refurbishment and lifecycle services that keep large reactors running as dependable baseload power assets.
"Record nuclear revenue growth in early 2026 and an increased full year nuclear revenue outlook to about $2.7b indicate that AtkinsRéalis Group is monetizing its nuclear backlog and recent contract wins, which directly supports higher future revenue and earnings quality."
What ultimately happens to earnings will hinge on how one pressure point feeds through to margins across those long duration reactor projects.
That pressure point is exactly where the full narrative for AtkinsRéalis Group shows how contract quality, execution risk and capital discipline could be accelerating or masking the true earnings power ahead.
NexGen Energy (TSX:NXE)
Overview:NexGen Energy is a Vancouver based uranium explorer developing the high grade Rook I project in Saskatchewan's Athabasca Basin for future nuclear fuel supply.
Market Cap:CA$7.6b
NexGen Energy may be relevant in a nuclear themed portfolio because the outlook is closely tied to Rook I supplying uranium fuel to reactors as utilities seek long term supply security. The business is still pre revenue and unprofitable, so the investment case centers on how that single project progresses from development to potential operation.
That single asset focus puts execution front and center, so it is worth seeing how the 1 key reward and 2 important warning signs (1 is major!) frames what could supercharge or stall NexGen Energy next.
Energy Fuels (TSX:EFR)
Overview:Energy Fuels is a U.S. based producer focused on uranium fuel for reactors, with added exposure to rare earths and mineral sands.
Operations:The business currently generates about $106 million in revenue primarily from its Uranium segment, with minor segment adjustments.
Market Cap:CA$2.6 billion
Energy Fuels matters for this nuclear screen because its uranium output directly feeds the reactor fuel supply chain while its rare earth expansion could reshape how critical materials reach clean power and electrification projects.
"Completion and commissioning of the White Mesa Mill rare earth separation Phase 2 expansion (potentially increasing monazite processing to 60,000 tonnes/year and enabling commercial-scale heavy rare earth production such as Dy/Tb) could establish Energy Fuels as a major western supplier, with any pricing impacts tied to western supply chain security priorities and electrification demand."
The key driver for Energy Fuels from here is how funding and execution pressures could influence future margins.
If you want to see how that funding and execution story could accelerate or stall, the full narrative for Energy Fuels shows what might be getting overlooked next.
