Westinghouse and Tetra Tech Canada Forge Strategic Collaboration to Advance Nuclear New-Build Projects in Ontario
Westinghouse Electric Company and Tetra Tech Canada have entered into a new strategic collaboration aimed at strengthening Canada’s nuclear energy future, marking an important step forward in the country’s clean energy transition. The two companies have signed a memorandum of understanding (MoU) that establishes a formal framework for cooperation on the development and deployment of Westinghouse’s AP1000® and AP300™ nuclear reactor technologies in Ontario.
The agreement brings together Westinghouse, a global leader in nuclear technology and services, with Tetra Tech Canada, a prominent provider of consulting, engineering, and technical services with a strong footprint in clean energy across North America and the United Kingdom. Together, the companies aim to support Ontario’s long-term electricity needs by enhancing domestic nuclear project development capabilities and accelerating the deployment of advanced reactor technologies.
Strengthening Canada’s Clean Energy Infrastructure
As Ontario and the broader Canadian energy system face increasing electricity demand driven by population growth, electrification, and industrial expansion, nuclear power is widely viewed as a critical component of a reliable, low-carbon energy mix. The collaboration between Westinghouse and Tetra Tech is designed to directly support this objective by leveraging complementary expertise in reactor technology, engineering, project execution, and regulatory compliance.
Under the MoU, Tetra Tech will provide engineering and technical support for AP1000 and AP300 projects, drawing on its extensive experience in nuclear services, environmental consulting, and infrastructure development. The company’s established presence in Canada and the U.K., combined with its large clean energy workforce, positions it as a key partner in advancing complex nuclear new-build initiatives.
The partnership also reflects a shared commitment to reinforcing Canada’s domestic nuclear supply chain. By working closely with Canadian engineering firms and service providers, Westinghouse aims to ensure that future nuclear projects deliver strong economic benefits alongside clean, reliable electricity.
Leadership Perspectives on the Agreement
Executives from both organizations emphasized the strategic importance of the collaboration and its alignment with Canada’s clean energy ambitions.
Sanjay Krishnan, Unit President for Nuclear Services at Tetra Tech, highlighted the company’s longstanding role in supporting nuclear and clean energy projects. He noted that Tetra Tech’s technical depth and regional experience make it well suited to contribute meaningfully to Canada’s nuclear expansion.
“As a global leader in high-end consulting and engineering, and with deep roots in Canada’s clean energy industry, Tetra Tech is uniquely positioned to collaborate with Westinghouse as the country expands its nuclear power generation to meet future energy needs,” Krishnan said. “This agreement enables us to apply our expertise to projects that will play a vital role in Canada’s low-carbon energy future.”
John Gorman, President of Westinghouse Canada, emphasized the agreement as part of the company’s broader commitment to Ontario and the Canadian nuclear sector.
“This agreement underscores Westinghouse’s commitment to investing in Ontario’s nuclear future by partnering with the exceptional product and service providers that have long been the foundation of the province’s supply chain,” Gorman said. “By working with trusted organizations like Tetra Tech, we aim to support Ontario’s energy goals and deliver successful outcomes for new nuclear projects.”
Expanding a Network of Canadian Partnerships
The MoU with Tetra Tech Canada is the latest in a series of agreements Westinghouse has signed with Canadian firms to support both domestic and international deployment of its AP1000 and AP300 reactor technologies. These partnerships are designed to ensure that Canadian companies play a central role in future nuclear projects, whether built at home or abroad.
Westinghouse estimates that for each AP1000 reactor unit constructed outside of Canada, the company could generate approximately CAD 1 billion in gross domestic product through Canadian suppliers and service providers. This underscores the significant export and supply-chain opportunities associated with participation in the global AP1000 program.
By integrating Canadian firms into its global nuclear projects, Westinghouse aims to strengthen Canada’s position as a leader in nuclear engineering, manufacturing, and services, while also supporting economic growth and job creation across multiple provinces.
AP1000 and AP300: Proven and Scalable Technologies
Owned by Canadian energy leaders Brookfield and Cameco, Westinghouse is currently the only nuclear vendor offering an advanced, fully operational Generation III+ reactor technology that is ready for deployment in Canada. The AP1000 reactor has already demonstrated strong operational performance at multiple sites worldwide and is widely recognized for its advanced safety features, modular construction approach, and cost-effective design.
In addition to the AP1000, Westinghouse’s AP300 small modular reactor (SMR) offers a scalable option for regions seeking flexible, lower-capacity nuclear generation. Together, the AP1000 and AP300 provide a range of solutions capable of supporting Canada’s evolving electricity needs while maintaining high safety and reliability standards.
Westinghouse has indicated that its advanced reactors could begin generating electricity in Canada as early as 2035, depending on project timelines and regulatory approvals.
Economic and Employment Benefits for Canada
The economic impact of new nuclear development using AP1000 technology is expected to be substantial. A four-unit AP1000 facility built in Canada could supply enough electricity to power at least three million homes, providing a stable source of baseload power for decades.
During construction, such a facility is projected to support approximately CAD 28.7 billion in gross domestic product, delivering significant economic activity across engineering, manufacturing, construction, and professional services. Once operational, the four-unit plant would generate an estimated CAD 8.1 billion in GDP annually and support around 12,000 high-quality, full-time Canadian jobs throughout its 60-plus-year operating lifespan.
Participation in the AP1000 supply chain also provides Canadian companies with opportunities to contribute to Westinghouse’s existing global reactor fleet. This includes six AP1000 reactors currently setting operational and performance records, 14 units under construction worldwide, and numerous additional projects in various stages of planning and contracting.
Positioning Nuclear for Canada’s Energy Future
The collaboration between Westinghouse and Tetra Tech Canada reflects a broader momentum behind nuclear energy as a cornerstone of Canada’s clean energy strategy. With increasing emphasis on decarbonization, energy security, and economic competitiveness, advanced nuclear technologies are gaining renewed attention from policymakers, utilities, and industry stakeholders.
By combining proven reactor technology with strong domestic engineering and project delivery capabilities, the partnership aims to help Ontario and Canada meet future electricity demand while supporting long-term economic growth and emissions reduction goals.
As Canada looks ahead to a more electrified and low-carbon economy, agreements such as this MoU signal a clear commitment to ensuring nuclear energy remains a reliable, innovative, and economically beneficial component of the national energy system.
