Ontario Takes the Lead: First Small Modular Reactor in G7 Underway

January 6, 2026

Ontario is making history by becoming the first in the G7 to construct a Small Modular Reactor (SMR). This significant development positions the province at the forefront of nuclear energy innovation, promising a cleaner and more secure energy future.

Key Takeaways

Ontario is pioneering the construction of the first Small Modular Reactor (SMR) within the G7.
This initiative aligns with a broader global trend towards advanced nuclear technologies for clean energy.
The project signifies a major step in energy independence and technological advancement.

A New Era of Nuclear Energy

Ontario’s groundbreaking project marks a pivotal moment in the global pursuit of advanced nuclear technology. Small Modular Reactors offer a more flexible and potentially faster approach to deploying nuclear power compared to traditional large-scale plants. This initiative is expected to bolster energy security and contribute significantly to climate change mitigation efforts.

Global Context and Ambitions

While Ontario leads the G7, other nations are also advancing their SMR programs. The United Kingdom, for instance, has selected Wylfa in North Wales as the site for its first SMRs, aiming to create thousands of jobs and invest billions in the local economy. This project, involving Rolls-Royce SMR, is part of the UK’s broader strategy to become a clean energy superpower and achieve energy independence.

Technological Advancements and Economic Impact

SMRs are designed to be smaller, quicker to build, and potentially more cost-effective than conventional nuclear reactors. They hold the promise of delivering clean power to millions of homes, supporting national infrastructure, and fostering innovation. The development of these reactors is anticipated to generate substantial economic benefits, including the creation of thousands of skilled jobs and significant infrastructure investment, as seen in both Ontario’s and the UK’s plans.

Future Outlook

Ontario’s pioneering SMR project is a testament to its commitment to advanced energy solutions. As the technology matures and deployment accelerates globally, SMRs are poised to play a crucial role in the transition to a low-carbon future, enhancing energy security and driving economic growth.
