 It was common to see buses with the old three and the new four digit numbers operating in service as Oshawa Transit buses.In 2006 staff at the former Oshawa Transit garage received a booklet titled "The End of an Era".The booklet illustrates the history of Oshawa Transit and includes photographs of the many different model buses used throughout the years with a write-up of memories of retired staff and the "Bus Roadeo".
