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

February 3, 2026

Ontario is set to make history as it begins construction on the G7’s first Small Modular Reactor (SMR). This pioneering project positions the province at the forefront of nuclear energy innovation, promising a significant boost to clean energy production and technological advancement.

Key Takeaways

Ontario is building the G7’s first Small Modular Reactor (SMR).
The UK is also advancing SMR technology, with Wylfa selected as the site for its first plant.
SMRs offer a smaller, quicker alternative to traditional nuclear reactors.
These projects aim to enhance energy independence and create skilled jobs.

Ontario’s Nuclear Milestone

Ontario is spearheading a new era in nuclear energy by commencing the construction of the first Small Modular Reactor (SMR) within the G7 nations. This initiative underscores Ontario’s commitment to clean energy solutions and its role as a leader in technological development.

UK’s SMR Ambitions

Meanwhile, the United Kingdom is also making significant strides in SMR technology. The Wylfa site in North Wales has been chosen to host the UK’s first small modular reactor nuclear power station. This project is anticipated to be the most substantial industrial investment in North Wales for a generation, expected to generate approximately 3,000 new jobs and inject billions of pounds into the local economy.

The Promise of Small Modular Reactors

Small Modular Reactors represent a significant evolution in nuclear power generation. These reactors are designed to be smaller and more efficient to construct compared to traditional nuclear power stations. The UK’s SMR project, utilizing reactors designed by Rolls-Royce SMR and supported by Great British Energy-Nuclear, aims to power the equivalent of around 3 million homes, bolstering the nation’s energy independence and contributing to its clean energy superpower mission.

Economic and Energy Impact

Both Ontario’s and the UK’s SMR initiatives are poised to deliver substantial economic benefits. The projects are expected to create thousands of skilled jobs, foster innovation, and attract significant investment. Furthermore, they are crucial components of broader strategies to achieve energy security and reduce carbon emissions, providing reliable, clean power for millions of homes and businesses.
