Created in 1946 by an Order in Council giving the company a mandate to provide service between major urban centres and to as much of the rural population as possible, STC was a wholly owned subsidiary of the Crown Investments Corporation of Saskatchewan.

Since the closure of STC and the discontinuation of Greyhound Canada service, these facilities have since been redeveloped for other uses such as offices and retail.

STC provided charter services to a number of groups and organizations every year in Saskatchewan.

Many corporations, sports teams, and clubs chose STC when travelling to functions both in and out of province.

The opposition NDP criticized the shutdown, saying it would hurt rural residents who relied upon the service for parcel delivery and transportation for medical appointments in larger centres.
