Ontario Takes the Lead: First Small Modular Reactor in G7 to Be Built in Province

January 6, 2026

Ontario is set to become the first in the G7 to construct a small modular reactor (SMR), marking a significant advancement in clean energy technology. This pioneering project positions Ontario at the forefront of nuclear innovation, aiming to bolster energy security and drive economic growth through advanced nuclear power.

Key Takeaways

Ontario is leading the G7 in the development of the first small modular reactor.
The initiative aims to enhance energy security and foster economic development.
This move signifies a commitment to advanced nuclear technology and clean energy solutions.

A New Era of Nuclear Power

Ontario’s initiative to build the first SMR in the G7 underscores a strategic commitment to embracing cutting-edge nuclear technology. Small modular reactors offer a more flexible and potentially faster approach to deploying nuclear power compared to traditional large-scale plants. This development is expected to play a crucial role in meeting future energy demands while contributing to climate change mitigation efforts.

Economic and Energy Implications

The construction and operation of SMRs are anticipated to generate substantial economic benefits, including the creation of high-skilled jobs and significant investment in the region. By diversifying its energy portfolio with advanced nuclear technology, Ontario aims to enhance its energy independence and provide a stable, low-carbon power source for its residents and industries. This project aligns with broader global efforts to transition towards cleaner energy sources and secure a sustainable energy future.

Global Context and Future Prospects

While Ontario leads the G7, other nations are also exploring SMR technology. The United Kingdom, for instance, has identified Wylfa in North Wales as the site for its first small modular reactor nuclear power station, with plans for up to eight mini reactors. This global interest highlights the growing recognition of SMRs as a vital component of future energy strategies, promising clean power for millions of homes and fostering international collaboration in nuclear innovation.
