Cornwall Ontario – One of Cornwall’s most popular attractions has opened its doors for the season – just in time for Tourism Week!

St. Lawrence Power Development Visitor Centre

The OPG Saunders Hydro Dam Visitor Centre is ready to welcome visitors for another summer of interactive learning at its beautiful facility on the banks of St. Lawrence River.

The OPG Visitor Centre offers a chance to learn about the history of the St. Lawrence Seaway and Power Project, one of Canada’s largest engineering projects. The Centre is equipped with interesting exhibits with explanations ranging from how electricity is generated in our area to information about Mohawk and Native American culture.

The fascinating building not only has a spectacular view of the St. Lawrence and RH Saunders Generating Station for visitors to enjoy, but also offers a wide range of unique activities. Visitors have the chance to chase a virtual electric eel up a ladder, spin a turbine to create electricity, watch videos about the creation of the dam, and learn to balance power production first-hand by becoming an operator for the day.

“We are excited about another tourism season here at the visitor centre,” says Matt Mulvihill, Communications Officer. “We hope to see many people come out to experience all that the centre has to offer.”

In addition to the exhibits, the centre offers a variety of free events throughout the summer. This year’s schedule includes:
