OPG's St. Lawrence Power Development Visitor Centre is located on the banks of the St. Lawrence River, east of the Robert H. Saunders Generating Station, in the west end of Cornwall, Ontario.

This environmentally-friendly building offers 13,000 square feet of fun and is a great outing for students and families:

  • Chase a virtual eel up a ladder to get over the power dam.
  • Spin a turbine and discover how much force is needed to make electricity.
  • Be an operator for a day and balance power production with the needs of other river users.
  • Watch a video about how the St. Lawrence Seaway and Power Project was built — one of Canada's largest-ever engineering projects.

OPG is committed to environmental sustainability and social responsibility. To reduce greenhouse gas emissions, the Visitor Centre offers priority parking for carpoolers, electric car refuelling, and pedestrian and bicycle path access. Please contact the Visitor Centre for details.
