Because of its small size, Saskatoon's only form of public transportation  is its bus system. Saskatoon Transit operates buses on 15 different routes through the city.  Two of the routes are known as DART (Direct Access Rapid Transit), which provide more frequent service to busier parts of the city.  Several routes converge at the downtown terminal (aka the "bus mall" on 23rd St. E.), Place Riel on the university campus, or one of the shopping mall terminals in the outlying parts of the city.

Service does not run 24 hours a day.  From Monday to Friday on most routes, service begins around 6 a.m. and ends around midnight. On Saturday, buses run from approximately 7 a.m. to midnight, and on Sunday from 8 a.m. to 10 p.m.

 As of 2010, fares for adults are $2.75 per ride.  Ten-ride packages are also sold for $21.  High school students with a valid high school ID and elementary school studentspay reduced fares. Children under age 5 accompanied by a fare-paying passenger ride for free.  Monthly, daily, and weekend family passes are also available, as well as special passes for senior citizens and post-secondary students.

The city also operates Access Transit, for passengers with disabilities who are unable to use the regular buses. Users of this service must first register before they can book trips.
