Ottawa-Carleton Regional Transit Commission 7621-7653
OC Transpo 7621-7653 were General Motors Diesel Division T6H-5307N buses built in 1976 and placed in service from December 1976 to January 1977.
Only five of these buses underwent rebuilds in 1999-2000, which were the following: 7632, 7635, 7642, 7644, and 7651. These were easily identifiable because they received a revised version of the older livery with the body painted white below the red stripe instead of silver.
All were retired by 2003.
