May 8, 2025

The government has announced the historic start of construction for the first Small Modular Reactor (SMR) in the G7 at the Darlington nuclear site.

Ontario’s energy demand is set to increase by 75% by 2050, making the case for expanded nuclear power. The four SMRs will provide enough clean, reliable, and affordable electricity to continuously power 1.2 million homes for 65 straight years.
