Prior to 1985, city councillors were elected
at large, with "regional and city" councillors who would serve on both city council and the
Durham Region council, and "local city" councillors who would only serve on city council. From 1985-2010, the city moved to a ward-based system, ensuring equal representation for all residents. The city returned to at large elections in 2010 and 2014, before returning to a ward-based system in 2018. Based on the current ward-based system, Oshawa voters elect: • one candidate for Mayor, elected city-wide; • one candidate for Regional & City Councillor, elected from their ward; and, • one candidate for City Councillor, elected from their ward. ==Committees==
