Built at Chatham, U.K., HMCS Okanagan was commissioned on 22 Jun 1968. She spent her whole career based out of Halifax as part of the 1st Canadian Submarine Squadron. On 28 Jul 1973, RFA Grey Rover collided with HMCS Okanagan in the Clyde near Faslane, Scotland. There were no injuries to the submarine's crew. Okanagan became the first Canadian submarine to do a Great Lakes cruise in Oct and Nov of 1990.
