The company was incorporated in 1932 as Fort Garry Motor Body and Paint Works Limited, in Winnipeg, Manitoba, Canada. In 1948 Greyhound Lines of Canada, at that time MCI's major customer, became a majority shareholder. MCI was purchased outright by Greyhound Lines in 1958. In 1962 a new plant was opened in Pembina, North Dakota to increase capacity as Greyhound widened its markets and switched increasingly from General Motors Diesel Division to its own in-house products. In 1974 another plant was opened in Roswell, New Mexico under the title Transportation Manufacturing Corporation (TMC)
