The exterior facades of the building were at their life cycle end and therefore a complete replacement of materials including: brick (east elevation only), insulations and air/vapour barriers, metal composite panels, curtain wall systems including windows and doors, roofing assemblies, etc. was undertaken to the six storey existing Ontario Power Generation Administration building and Erection Bay.
The Control Room relocation from the 3rd floor to the penthouse (6th floor) allowed for the expansion of services across Eastern Ontario. This expansion combines two existing locations and is in essence the most important impacted project for OPG in 2017. OPG employs a staff of about 90 people at the station, most of whom live in the Cornwall area. Through their Corporate Citizenship Program, OPG provides support to nearly 50 community programs and local not-for profit agencies. The station is an important part of Ontario’s electricity system, providing clean, renewable power all year round.
The visitor centre recounts, through exhibits, artifacts and video, the many colourful stories associated with the facility, including the flooding of the Lost Villages and relocation of residents. The centre also tells the history of power generation in Ontario, construction of the St. Lawrence Seaway and Power Project and the more recent creation of OPG, when Ontario Hydro was split into separate generating and transmission companies. An exhibit also recounts the history of the Akwesasne First Nations People.
