Carleton is a federal electoral district in Ontario, Canada, represented in the House of Commons of Canada from 1867 to 1968 and since 2015. It was represented in the Legislative Assembly of Upper Canada from 1821 to 1840 and in the Legislative Assembly of the Province of Canada from 1841 until 1866. It is currently represented by Bruce Fanjoy, who defeated Conservative Party leader Pierre Poilievre in 2025.
The original riding was created by the British North America Act 1867. However, the riding had existed since 1821 in the Parliament of Upper Canada and the Parliament of the Province of Canada. It originally consisted of Carleton County. In 1966, it was redistributed into the new electoral districts of GrenvilleâÂÂCarleton, Lanark and Renfrew, Ottawa Centre, Ottawa West and OttawaâÂÂCarleton.
This riding was re-created by the 2012 electoral redistribution from parts of NepeanâÂÂCarleton (59%), CarletonâÂÂMississippi Mills (41%) and a small portion of Ottawa South. It was contested in the 2015 federal election.

The federal riding consisted initially of Carleton County. In 1882, it was redefined to consist of the townships of Nepean, North Gower, Marlboro, March, Torbolton and Goulbourn, and the village of Richmond. In 1903, it was redefined to consist of the county of Carleton, excluding the city of Ottawa and the townships of Gloucester and Osgoode.
In 1914, it was redefined to include parts of the city of Ottawa not included in either the electoral district of Ottawa or Rideau Ward of Ottawa.
In 1924, it was redefined as consisting of the county of Carleton, excluding the townships of Gloucester and Osgoode and that part of the city of Ottawa lying east of a line drawn from south to north along the Canadian Pacific Railway line, Somerset Street, Bayswater Avenue, Bayview Road, and Mason Street to the Ottawa River.
In 1933, it was redefined as consisting of the county of Carleton, excluding the township of Gloucester, the town of Eastview, the village of Rockcliffe Park and the part of the city of Ottawa lying east of Parkdale Avenue.

The electoral district was abolished in 1966 when it was redistributed between GrenvilleâÂÂCarleton, Lanark and Renfrew, Ottawa Centre, Ottawa West and OttawaâÂÂCarleton ridings.
The riding was recreated in 2015 by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order. Initially, the riding was known as RideauâÂÂCarleton. 40.58% of the riding came from the riding of CarletonâÂÂMississippi Mills, 59.37% from NepeanâÂÂCarleton and 0.04% from Ottawa South. The core of the riding came from the more rural eastern portion of the old NepeanâÂÂCarleton. It came into effect upon the call of the 2015 Canadian federal election held in October of that year.
The 2022 Canadian federal electoral redistribution resulted in much of the riding's few urban polls being swapped for other rural areas within the City of Ottawa.
The area north of Hazeldean Road has been reassigned to the new Kanata riding.
The largely rural portions west of the 417 and north of Craig's Side Road / Murphy Side Road / Constance Lake Road / Berry Side Road has been reassigned from the old KanataâÂÂCarleton riding to Carleton. This includes several rural communities: Fitzroy Harbour, Dunrobin, Kinburn and Constance Bay.
Another rural area (south of Bells Corners, west of the 416 and south of Barnsdale Road) was allocated to the riding from the Nepean riding.
In the east, parts of Orléans and GlengarryâÂÂPrescottâÂÂRussell south of Highway 417 and within the city of Ottawa, and that part of Ottawa South south of the 417 and Hunt Club Road and east of Hawthorne Road, were moved into the riding.
The Findlay Creek area was reallocated to Ottawa South.
