Bruce A is a 4 x 750-MW CANDU nuclear plant commissioned in the 1970s that was shut down in 1997/98. Bruce Power leased the Bruce plant in 2001 and decided to restart initially two of the Bruce A units (Units 3 and 4) to take advantage of opportunities to sell electrical energy within the competitive Ontario market. In October 2005, Bruce Power announced a
long-term agreement to restart Units 1 and 2 so that the units can operate for an additional 25 years.

Restarting the four units will boost Bruce Power’s output to more than 6,200 MW, making it the source of about 25 percent of Ontario’s electricity on a typical day.

Following the restart, the company’s eight units will supply the annual power needs of more than four million homes.
