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

January 13, 2026

Ontario is set to become the first in the G7 to build a small modular reactor (SMR), marking a significant advancement in clean energy technology. This pioneering project aims to bolster the province’s clean electricity supply and contribute to Canada’s net-zero goals.

Key Takeaways

Ontario is pioneering the development of the first Small Modular Reactor (SMR) within the G7.
The initiative is a crucial step towards enhancing the province’s clean energy capacity.
This project aligns with Canada’s broader objectives for achieving net-zero emissions.

A New Era for Clean Energy

Ontario is forging ahead in the global race for advanced nuclear technology by initiating the construction of the first small modular reactor (SMR) within the G7. This groundbreaking development positions the province at the forefront of clean energy innovation, promising to significantly enhance its electricity grid with reliable, carbon-free power.

The strategic deployment of SMRs is seen as a vital component in Ontario’s long-term energy strategy. These advanced reactors offer a flexible and scalable solution for generating electricity, complementing existing renewable sources and ensuring a stable power supply for decades to come. The project is expected to create numerous jobs and stimulate economic growth within the province.

Advancing Net-Zero Goals

This initiative is a cornerstone of Canada’s commitment to achieving net-zero emissions by 2050. By embracing SMR technology, Ontario is demonstrating a tangible pathway to decarbonize its energy sector. Small modular reactors are designed with enhanced safety features and can be deployed more quickly and cost-effectively than traditional large-scale nuclear plants, making them an attractive option for meeting growing energy demands while reducing greenhouse gas emissions.

The provincial government has expressed strong support for this technological leap, recognizing its potential to not only meet domestic energy needs but also to establish Canada as a global leader in the SMR industry. Further details regarding the specific location and timeline for the reactor’s operation are anticipated as the project progresses.
