Transit services in Sudbury began with the Sudbury & Copper Cliff Suburban Electric Railway (11 November 1915 - Fall 1951). The SCCSER acquired a secondary system, City Bus Lines (1947–1950), in 1950. In the fall of 1951, the company reorganized as Sudbury Bus Lines Limited (1951–1966). This later became an umbrella corporation, Laurentian Transit (Sudbury) Limited (1966–1972), for the joint operation of transit in Sudbury by Nickel Belt Coach Lines, Local Lines Limited, and DeLongchamp Cartage Company. Until 1972 the system was privately operated, but in that year it was taken over by the City of Sudbury Community Services Department under the name of Sudbury Transit (1972–2000). Sudbury Transit served an area population of 92,000 with a vehicle fleet of 33 buses and employed 103 workers (1991).
