Community Power Expo
Ever wonder how electricity is made or what Ontario’s electric future looks like?
Join us on Saturday, Sept. 20 for OPG’s Community Power Expo and dive into the dynamic world of clean energy!
Visit one of two locations:
- The Darlington Energy Complex at 1855 Energy Dr, Courtice
- Pickering Nuclear Generating Station at 1675 Montgomery Park Rd, Pickering
This FREE interactive, family-friendly event brings together community members, industry partners, and energy experts for a day of discovery and fun. This year’s event promises hands-on activities, live demonstrations, and opportunities to connect with the people powering Ontario’s clean energy future.
To support our mission to be good neighbours, non-perishable food donations are encouraged and will be accepted at both locations to support local food banks.
Tuesdays on the Trail recap
That’s a wrap on another successful season of our Tuesdays on the Trail program! For more than 20 years, OPG’s Pickering and Darlington sites have offered family-friendly activities for children aged four to 10 throughout July and August.
Thanks to the generosity of our dedicated community partners and student volunteers, this year’s program featured a variety of fun, free and educational activities at Alex Robertson Park in Pickering and along the Waterfront Trail in Courtice.
Families enjoyed programming with the Pickering Public Library and Clarington Library, Museums and Archives; Scientists in School; Soper Creek Wildlife Rescue; and Durham Community Health Centre.
We look forward to seeing you again next summer!

Darlington licence renewal update
Earlier this year, the Canadian Nuclear Safety Commission (CNSC) held a two-part public hearing to consider OPG’s application to renew the Power Reactor Operating Licence for the Darlington Nuclear Generating Station for a 30-year term.
During part two of the hearing in June, Indigenous Nations and communities, stakeholders, community groups, and the public had the opportunity to comment on OPG’s application through written interventions and oral presentations.
OPG has safely and reliably operated nuclear stations for more than 50 years. The Darlington station provides clean baseload power that is critical to meeting Ontario’s growing energy needs. The station is currently undergoing a multi-year refurbishment to safely extend operations. To learn more about the Refurbishment project visit opg.com/darlingtonrefurb.
A decision from the Commission is expected this fall.
For more information, including recordings of the public hearings, visit the CNSC website at www.cnsc-ccsn.gc.ca. Additional information is also available on our Operating Licences page.
OPG seeks licence renewal at Pickering
In June, OPG submitted an application to the CNSC for early renewal of both the Pickering Nuclear Generating Station (NGS) Power Reactor Operating Licence (PROL) and the Pickering Waste Facility Operating Licence (WFOL) for a 10-year term from Jan. 1, 2027 to Dec. 31, 2036. The CNSC will hold a 2-part public hearing on April 1, 2026, and the week of June 22, 2026 to consider OPG’s application.
Both licences are valid until Aug. 31, 2028, with authorization for Units 5 to 8 to operate until Dec. 31, 2026, up to a maximum of 305,000 equivalent full power hours.
We will continue to put our communities first. Refurbishing the Pickering NGS will provide many benefits to customers, the economy, and the environment and secure more than 2,100 MW of clean, reliable power for more than 30 years, ensuring a stable energy supply for Ontarians.
Ontario green lights North America’s first grid-scale SMR
In early May, the Province of Ontario approved OPG to begin construction of North America’s first commercial, grid-scale Small Modular Reactor (SMR) at the Darlington New Nuclear Project (DNNP) site.
Through the DNNP, OPG plans to construct and operate four grid-scale BWRX-300 SMRs (pending regulatory approvals). The first unit, scheduled to come online by the end of 2030, is expected to deliver 300 megawatts (MW) of safe, reliable, low-carbon electricity — enough to power approximately 300,000 homes.
This historic project marks the province’s first new nuclear build in over 30 years. Once complete, OPG’s SMR fleet will contribute significantly to local, provincial and national economies, support Ontario’s growing electricity needs and shine an international spotlight on the Canadian nuclear supply chain.
Harriet Brooks arrives at the DNNP site
OPG’s Tunnel Boring Machine (TBM) - named Harriet Brooks after Canada’s first female nuclear physicist - has successfully arrived on Canadian soil.
After travelling from the Netherlands, then making its way from the Port of Oshawa through 15 carefully coordinated shipments, this critical piece of equipment is now ready and available for assembly at the project site in early 2026.
Once operational, the TBM will bore and line the 3.4 kilometre-long Condenser Cooling Water tunnel—an essential element for bringing OPG’s SMR fleet online.
Did you know?
The TBM’s namesake, Harriet Brooks, contributed significantly to our understanding of nuclear physics in the early 20th century through her discovery of radioactive transformation and the radioactive gas radon. While her legacy encapsulates her important work, it is also a reminder of the systemic barriers women in the energy sector have and continue to face, and a call to action for diversity, inclusion and representation.
Powering Possibilities in Port Hope
To help meet the growing demand for electricity in the province, the Ontario government has asked Ontario Power Generation (OPG) to explore the potential for new nuclear generation at its Wesleyville site. As a first step in this process, OPG has started early engagement with the Municipality of Port Hope and the Williams Treaties First Nations.
Impact Assessment
Major nuclear projects in Canada are subject to an Impact Assessment (IA) led by the Impact Assessment Agency of Canada (IAAC) and the Canadian Nuclear Safety Commission. Later this year, OPG will submit an Initial Project Description (IPD) to the IAAC. The IPD will detail the potential of hosting up to 10,000 megawatts (MW) of nuclear power generation at the Wesleyville site. The IPD submission is the first step in the IA and kicks off a multi-year process to identify and assess potential impacts, mitigation measures, and enhancement to positive impacts of the project.
Get involved and stay in touch
Our outreach and engagement will be ongoing and consistent as more information on the potential for new nuclear at Wesleyville becomes available.

Can-struction: Building to make a difference
This past spring, OPG partnered with Feed the Need Durham, collecting 244 pounds of food, providing over 1,037 meals for families in need through a collective food drive and creative “Build what you CAN” challenge at Darlington.
