3 Canadian Nuclear Stocks To Own In September 2026

Oil nears $100 a barrel as Middle East disruptions ripple through energy supply chains, and Canadian investors are looking harder at power sources that are less exposed to fuel price swings. That is where Canadian nuclear energy stocks come into focus, offering exposure to long term electricity demand backed by large, upfront infrastructure. This article highlights three of the most interesting nuclear related stocks from our screener and what sets each apart.

The three nuclear related stocks covered below are only a small sample, and the same screen surfaced 57 more companies with equally compelling narratives that do not fit into a single article. If you want to identify potential opportunities that fit your own risk profile, head straight into the Nuclear Energy Stocks screener to filter, analyze, and focus on the nuclear energy stocks that best match your convictions.

Bird Construction (TSX:BDT)

Overview: Bird Construction is a Canadian contractor that builds and maintains complex industrial, infrastructure, and institutional projects, including specialized civil and electrical work for nuclear and other energy facilities.

Operations: Bird Construction generates all its CA$3.7b revenue from the general contracting sector in Canada, with projects concentrated across industrial, building, and infrastructure markets.

Market Cap: CA$3.9b

For investors focused on the nuclear energy theme, Bird Construction matters because its heavy civil and electrical expertise plugs directly into the physical build out of nuclear sites, even though the business remains broadly diversified across Canadian infrastructure.

"Bird is poised to benefit from the substantial, multi-year government investment in Canadian infrastructure, with record backlog and strong pipeline of large, nation-building projects (defense, healthcare, energy, transit). Accelerating demand for energy transition and green building projects, including nuclear, LNG, wind, hydro, and sustainable/LEED certified facilities, is resulting in higher margin, specialized contracts."

What happens to Bird Construction’s earnings power if a single assumption about the mix of higher margin specialized projects shifts.

That shift in project mix is exactly what the full narrative for Bird Construction unpacks, showing how accelerating infrastructure demand could reshape earnings resilience and risk for Bird Construction.

Denison Mines (TSX:DML)

Overview: Denison Mines is a Toronto based uranium exploration and development company focused on advancing its high grade Wheeler River uranium project in Canada.

Operations: Denison Mines currently records CA$4.1 million in revenue from mining activities, reflecting its early stage uranium project development focus.

Market Cap: CA$4.3 billion

Denison Mines provides direct exposure to the uranium fuel side of nuclear energy. The Wheeler River project acts as a potential anchor that could feed reactors rather than just supply equipment or services.

"Denison Mines is expected to progress further in the development of its uranium assets and strengthen its position as a key future supplier of uranium in North America."

Consider what could happen to Denison Mines’ long term earnings power if a single assumption about funding costs or uranium pricing shifts against expectations.

That kind of pressure on assumptions is exactly what the full narrative for Denison Mines tackles, mapping how funding risks and uranium price scenarios could accelerate or stall the long term potential of Denison Mines.

Energy Fuels (TSX:EFR)

Overview: Energy Fuels is a Lakewood based producer that focuses on uranium for nuclear fuel, with additional rare earth and heavy mineral sands businesses.

Operations: Energy Fuels currently generates about US$105.8 million in revenue from its uranium segment, which is directly tied to nuclear fuel.

Market Cap: CA$5.0 billion

Energy Fuels matters for nuclear focused investors because it combines uranium production with rare earth processing at a time when secure fuel and critical material supply chains are a priority for governments and utilities.

"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, capturing price premiums driven by western supply chain security and increasing electrification demand, supporting long-term revenue and margin upside."

What happens to Energy Fuels’ uranium driven earnings profile if a single assumption about funding availability for its expansion plans shifts?

If that funding picture changes, the full narrative for Energy Fuels shows how Energy Fuels could accelerate, stall, or even decouple uranium and rare earth cash flows.
