Powering Ontario’s future: Nuclear energy job opportunities in Canada


As Ontario invests in long-term energy security, the province's nuclear sector is entering a historic new chapter, one that's creating high-quality careers, strengthening local communities, and reaffirming Canada's leadership in nuclear technology.

At Candu Energy Inc., an AtkinsRéalis company, we're proud to be at the heart of this progress. As the original equipment manufacturer of CANDU® reactors and a trusted partner on major nuclear infrastructure projects, we're helping to build something that lasts, economically, environmentally, and nationally.

Nuclear is driving energy security in Ontario

From the refurbishment of Darlington Nuclear Station to the development of Canada's first grid-scale Small Modular Reactor (SMR), Ontario is making bold investments to secure a reliable, stable power supply for generations.

These long-term projects reduce dependency on global energy markets and deliver made-in-Ontario solutions to meet growing demand. With nuclear providing consistent baseload power, the province can depend less on volatile imports, and more on homegrown expertise.

For engineers and technical professionals, that means contributing to projects with legacy-level impact: powering Ontario through to the end of the century.

Local jobs, local supply chains, long-term value

Ontario's nuclear industry is more than an energy solution, it's a job creator and economic engine. We are proud to support local businesses, expand domestic supply chains, and create high-quality roles that can last a lifetime.

At Candu Energy Inc., whether you're in engineering, safety, operations, digital systems, or project delivery, your work creates opportunities that reach far beyond your own career, fueling growth and prosperity across entire communities.

Clean power that clears the air

We've been instrumental in delivering nuclear projects that have had a measurable impact on Ontario's air quality. Our engineering and project delivery teams have supported key refurbishments, like those at Darlington, that replaced coal-fired generation and helped eliminate smog days across the province.

This isn't a future promise, it's a result already achieved. By extending the life of CANDU® reactors and enabling new builds like Ontario's first SMR, we're helping reduce air pollutants that directly affect public health.

For skilled professionals, joining Candu Energy Inc. means contributing to cleaner skies and healthier communities across Ontario, through proven nuclear solutions that are already making a difference. 

Build your future in a nuclear job in Canada with Candu Energy Inc.

We are the original equipment manufacturer of CANDU technology, one of the most proven and robust reactor designs in the world. It's a point of national pride and technical leadership that sets us apart in the global nuclear industry.

Our teams maintain, modernize, and expand this technology right here in Ontario, ensuring it remains a cornerstone of the province's energy infrastructure for decades to come.

With a strong legacy and future-focused mindset, we are creating opportunities for talented professionals ready to be part of something bigger. From large-scale refurbishments to the future of SMRs, we offer careers that blend innovation, impact, and purpose.

Explore nuclear careers in Ontario Canada today and help build a future powered by progress, pride, and purpose.
