Have Your Say: World's Largest Nuclear Station

Posted: 8th February 2026

Let’s look at the cleaner, safer and lower cost options


Have Your Say: World’s Largest Nuclear Station

Ontario Power Generating (OPG) wants to build the world’s largest nuclear station in Port Hope on the shore of Lake Ontario.

The federal Impact Assessment Agency of Canada (IAAC) is currently accepting public comments on OPG’s proposal — until Feb. 11.

This is your chance to ask federal decision-makers to seriously examine whether energy efficiency, renewables, and energy storage could meet Ontario’s electricity needs faster, at lower cost, and with less risk than building another large nuclear plant.

Public input matters — this is an important opportunity to influence the review.

How to Submit Your Comment

Submit your comment either through the IAAC portal, or email your comments directly to [email protected]. Deadline to submit: midnight Feb. 11. 

Read our comments to the IAAC – feel free to grab any ideas that resonate with you to help craft your own comments.

What to Ask For in Your Comment

Please ask the IAAC to direct OPG to look at the cleaner, safer and lower cost options (e.g., offshore wind, solar, storage) to building the world’s largest nuclear station. 

Consider asking the IAAC to require OPG to fully evaluate whether:

  • Energy efficiency could reduce the need for new generation
  • Renewable energy (like wind and solar) could be deployed faster
  • Energy storage could improve reliability without new nuclear risks
  • These alternatives would cost less and reduce financial risks for ratepayers
  • These options would avoid the long-term radioactive waste and accident risks associated with nuclear power

Deadline

All comments must be submitted by midnight on Wednesday, February 11.

Even a short message helps. The more people who speak up, the stronger the case for safer, lower-cost energy solutions.
