Oshawa Transit was a public transit operator in Oshawa, Ontario, Canada, from 1960 to 2005. Its only garage and headquarters was located at 710 Raleigh Avenue in Oshawa. On January 2, 1960 at the request of the City of Oshawa, the Oshawa Public Utilities Commission (PUC) undertook the operation of the transit system for the city. The Oshawa PUC did this until June 1996 when City Council created a new Oshawa Transit Commission. It operated until December 31, 2005 at which time Oshawa Transit was merged with Whitby Transit, Ajax-Pickering Transit, and Clarington Transit in Durham Region to form Durham Region Transit on January 1, 2006.
