Project lead: Ontario Power Generation
Ontario Power Generation is advancing preparations for the refurbishment of the Pickering Nuclear Generating Station, a major long-term infrastructure project that will support Ontario’s electricity system for decades to come.
The refurbishment represents one of the largest economic opportunities in the region’s history, strengthening local businesses, creating thousands of jobs, and reinforcing Pickering’s role as a cornerstone of Canada’s clean energy future. For more information on the Pickering Nuclear Refurbishment Project, visit Invest Pickering.
As planning and related work continue, residents may notice increased project activity and construction-related traffic in areas connected to the Pickering Nuclear site and surrounding road network.
This project is expected to support long-term energy reliability, local employment, and broader economic benefits across Ontario.
Construction highlights/impacts:
- To help manage the impacts of increased daily vehicle and heavy-equipment traffic, the City is actively working with OPG on planned upgrades to Sandy Beach Road and Montgomery Park Road ahead of the refurbishment, as per the Council approved Road Servicing Agreement (Resolution # 767/25).
- Phase 1 works on both roads were completed in 2025. Phase 2 works, which will bring the project to completion, are expected to commence in April 2026 and be completed by year end. Road closures and detour routes will be in effect during construction.
- Pickering Nuclear Refurbishment work is scheduled to begin in January 2027 and span approximately seven to eight years.
