Motor Coach Industries (MCI) is a brand of motor coaches manufactured by New Flyer Industries, a North American bus manufacturer based in Canada. The company was incorporated in 1933 as Fort Garry Motor Body and Paint Works Limited, in Winnipeg, Manitoba, Canada by Harry Zoltok. In 1948, Greyhound Lines of Canada, at that time MCI's major customer, became a majority shareholder when it purchased 65% of the company. MCI was purchased outright by Greyhound Lines in 1958. In December 1986, Greyhound was split, with Greyhound Lines being sold to an investor group, and Greyhound Lines of Canada, MCI and TMC remaining part of The Greyhound Corporation, which was renamed Dial, Inc. in 1991.
In 1987, Greyhound Corporation bought the transit bus manufacturing operations of General Motors Diesel Division (GMC), which was based in Canada. MCI also took over production of GM's RTS model, transferring production to TMC. MCI also purchased the GM bus assembly plant in Saint-Eustache, Quebec, which then produced GM's Canadian transit bus model, the Classic. TMC ceased production of the older MCI vehicles in 1990 to concentrate on manufacturing the RTS, and on the "A-Model" intercity coaches.In 1993 MCI became an independent corporation, Motor Coach Industries International Inc
