Cornwall Ontario – The Power Visitor Centre has opened its doors for another thrilling summer of interactive learning.

The St. Lawrence Power Development Visitor Centre kicks off the tourist season by welcoming groups of all ages to the centre, which is situated on the banks of the St. Lawrence River.

The Visitor Centre offers a chance to learn about the history of the St. Lawrence Seaway and Power Dam, 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 waterfront 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.”

Indeed there are many things happening at the Visitor Centre this summer. They will be hosting various events in partnership with the St. Lawrence River Institute of Environmental Sciences.  Families will have the chance to discover science and nature within our community with these workshops and events happening throughout the summer:
