Ottawa Transportation Commission

Ottawa Transportation Commission was the public transit operator for the city of Ottawa from 1948 until the creation of OC Transpo in 1973.

OTC took over streetcar operations from the Ottawa Electric Railway, but they were gradually abandoned for trolley bus and bus operations. Some streetcars were sold to the Toronto Transit Commission.
