Before 2006, the ward was known as Rideau Ward and was increased in coverage as the new ward of Stittsville was created from parts of the former Kanata and Goulbourn Wards due to population growth in Stittsville as well as new developments in the west portions of the former city of Kanata. Portions of Goulbourn Township was added to Rideau Ward. In 2014, the new Blackstone subdivision was transferred from Rideau-Goulbourn Ward to Stittsville Ward.
Prior to being amalgamated into Ottawa, this areas was represented on Regional council by Western Townships Ward.
There are plans underway to change the name of the ward, due to Goulbourn's namesake, Henry Goulburn's attachment to slavery in the 19th century.
