Quick answer: Canada’s nuclear sector is entering a multi-year period of refurbishment, new-build and supply-chain activity. The federal government says the sector supports about 90,000 direct and indirect jobs, with about 90% of nuclear-industry jobs classified as high-skilled. For job seekers, the opportunity is much broader than nuclear engineering: skilled trades, technologists, operations, radiation protection, quality, project controls, cybersecurity and supply-chain roles all contribute to nuclear projects.
Last updated: September 24, 2026. GoHires distinguishes current employment from project forecasts. A project announcement or projected job count is not the same as an open vacancy.
Why nuclear careers are worth watching now
Canada’s Nuclear Energy Strategy describes nuclear power as a long-term component of the country’s electricity system and industrial supply chain. It says nuclear supplies about 13% of Canada’s electricity and contributes about $22 billion to the economy annually. Ontario is the centre of current activity, but the supply chain and emerging-project pipeline extend beyond the province.
The important career signal is not a single announcement. It is the overlap of three long-duration work streams: refurbishment of existing CANDU stations, construction of new small modular reactors, and continued operation, maintenance and supply-chain work. Those streams create different hiring windows and require different qualifications.

| Digital and cyber | Cybersecurity, OT security, data, digital systems | IT/cyber education plus industrial or nuclear-domain knowledge | Plant modernization, protection of critical infrastructure |
What nuclear jobs pay in Canada
Salary comparisons require care because nuclear employers use many occupational classifications and compensation structures. Job Bank’s wage data are useful national benchmarks, not promises of what a particular nuclear employer will pay.
| Occupation | Canada median | Ontario median | Source period |
|---|---|---|---|
| Nuclear engineer (NOC 21301) | $45.67/hour | $46.42/hour | 2023-2024 Labour Force Survey, wages updated Nov. 19, 2025 |
| Nuclear technologist (NOC 22301) | $35.00/hour | $38.00/hour | 2023-2024 Labour Force Survey, wages updated Nov. 19, 2025 |
Job Bank also reports that 92.4% of workers in the nuclear-engineer occupational group and 94.3% in the nuclear-technologist group receive at least one non-wage benefit nationally. Benefits can include pensions, health coverage and paid leave. Actual nuclear compensation varies by employer, union status, experience, shift work, overtime and location.
Major projects and the hiring windows they can create
Pickering refurbishment
Ontario’s Pickering refurbishment is a major multi-year workforce signal. The key distinction for job seekers is between enabling and construction work, reactor refurbishment, and later long-term operations. Government job projections should be treated as forecasts rather than vacancies. Candidates should watch Ontario Power Generation and awarded contractors for actual postings and apprenticeship opportunities.
Darlington new nuclear and SMRs
Ontario Power Generation is developing new nuclear capacity at Darlington using small modular reactor technology. OPG says the Darlington New Nuclear Project could support 18,000 jobs during construction and 3,000 ongoing jobs. These are project estimates, not a count of positions currently available.
Existing nuclear operations and supply chain
Long-term careers also exist outside major construction cycles. Operating stations need maintenance, engineering, operations, chemistry, radiation protection, security, IT, procurement and asset-management capability. Suppliers support components, engineering services, fabrication, inspection and specialized project delivery.
How project stage changes the jobs available
| Project stage | Roles that tend to become more relevant | What job seekers should watch |
|---|---|---|
| Planning and licensing | Engineering, environmental, regulatory, Indigenous/community engagement, project controls | Regulatory milestones, engineering contracts |
| Site preparation | Civil construction, surveying, equipment, safety, logistics | Early works contracts and contractor mobilization |
| Major construction/refurbishment | Trades, supervisors, QA/QC, engineering, schedulers, procurement | Prime contractor and union-hall hiring |
| Commissioning | Operators, instrumentation, testing, engineering, safety | System turnover and commissioning schedules |
| Operations | Operators, maintenance, engineering, radiation protection, chemistry, cyber | Permanent employer recruitment and graduate programs |
Education and certification pathways
There is no single nuclear credential that fits every career. Engineers generally begin with an accredited engineering degree and may pursue professional engineering licensure. Technologist roles commonly begin with a relevant college technology program. Skilled-trade candidates normally enter through apprenticeship and the certification requirements applicable to their trade and province. Plant-specific roles can require extensive employer training and, for certain functions, regulatory certification.
Do not pay for a generic private “nuclear certification” simply because it contains the word nuclear. Start with real job descriptions from OPG, Bruce Power, major contractors and suppliers, then identify the credential repeatedly requested for your target role.
A practical 30-day nuclear-career plan
- Choose a career family. Decide whether you are targeting engineering, trades, technology, operations/safety, project delivery or digital/cyber.
- Map your transferable skills. Construction, utilities, aerospace, defence, manufacturing and other regulated industries can provide relevant experience, but do not claim nuclear experience you do not have.
- Study five real postings. Record recurring credentials, security requirements, software, standards and experience.
- Follow projects by stage. A licensing milestone may favour engineering and regulatory roles, while construction mobilization changes the mix toward trades and project delivery.
- Track employers and contractors. Watch OPG, Bruce Power and major engineering/construction suppliers rather than relying only on general job boards.
- Build the missing credential. Prioritize the credential that appears repeatedly in real postings.
- Tailor your resume. Emphasize safety culture, quality, regulated work, technical documentation and relevant project experience where truthful.
Risks and limitations
Nuclear projects are highly regulated and can change schedule, scope or procurement strategy. Regulatory approval is not automatic. Government and company job figures often describe economic impact or projected employment over a project life, not positions available today. Some roles require security screening, site-specific training, union pathways or professional licensing. Candidates should verify requirements against the employer and regulator before making an education or relocation decision.
Where GoHires sees the strongest opportunity
GoHires interpretation: the strongest opportunity is at the intersection of a durable technical skill and nuclear-domain knowledge. An experienced electrician, millwright, engineer, project-controls specialist or cybersecurity professional may have a clearer path than someone pursuing a vague “nuclear career” without an occupational foundation. Nuclear should therefore be treated as an industry layer on top of a credible profession or trade.

FAQ
Do I need a nuclear engineering degree to work in nuclear?
No. Nuclear employers and projects use engineers, skilled trades, technologists, project professionals, cybersecurity specialists and many other occupations. Requirements depend on the role.
