Due to the increase in ridership the service has been approved for articulating buses primarily used for the largest routes and during rush-hour times.

Greater Sudbury Transit features 59 buses on 25 routes servicing the city centre and outlying neighbourhoods such as Capreol, Chelmsford, Lively and Falconbridge.

Sudbury Transit served an area population of 92,000 with a vehicle fleet of 33 buses and employed 103 workers (1991).

As of December 1, 2009, Greater Sudbury Transit buses feature a fully operational audio/visual stop announcement system for passengers who are hearing and/or visually impaired.

Greater Sudbury Transit also operated a trans-cab service for any outlying area which does not receive bus service (including Long Lake, Richard Lake, Radar Base, Skead, Wahnapitae, Whitefish and Dowling) which provides a taxi from the individual's home to a transit bus stop.

As of April 12, 2012, Greater Sudbury Transit guaranteed seven bus routes (101, 182, 301, 501, 701, 702, 703) that would always be equipped with bike racks.

City staff have indicated that following the construction to the new transit garage there will theoretically be sufficient space within to equip the whole fleet with bike racks.

Some ideas which were considered included a switch to electric buses (which would make Greater Sudbury Transit one of the first transit agencies in Canada to do so), improvements to cycling-transit integration, adoption of "smart" fare card technology, and a renewal of the existing diesel bus fleet.
