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 parts of
Carleton County.

1867–1966 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. In 1947, it was redefined as consisting of the county of Carleton, excluding the township of Gloucester, the town of Eastview and the village of Rockcliffe Park, and including the parts of Victoria and Elmdale wards in the city of Ottawa west of Parkdale Avenue, the part of Dalhousie ward south of Carling Avenue, the part of Capital ward south of Carling Avenue and Linden Terrace, and the part of Riverdale ward south of Riverdale Avenue and west of Main Street. In 1952, it was redefined as consisting of the county of Carleton (excluding the township of Gloucester, the town of Eastview and the village of Rockcliffe Park), and the part of the city of Ottawa west of a line drawn from north to south along Parkdale Avenue, east along Carling Avenue, north along O'Connor Street, east along Linden Terrace to the
Rideau Canal, south along the canal, east along Echo Drive, northeast along Riverdale Avenue, south along Main Street, southwest along the Rideau River. The electoral district was abolished in 1966 when it was redistributed between
Grenville—Carleton,
Lanark and Renfrew,
Ottawa Centre,
Ottawa West and
Ottawa—Carleton ridings.
Riding revival (2012) 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
Rideau—Carleton. 40.58% of the riding came from the riding of
Carleton—Mississippi Mills, 59.37% from
Nepean—Carleton and 0.04% from
Ottawa South. The core of the riding came from the more rural eastern portion of the old Nepean—Carleton. It came into effect upon the call of the
2015 Canadian federal election held in October of that year.
2022 Federal redistribution 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 was 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 added from
Kanata—Carleton. This included several rural communities, namely
Fitzroy Harbour,
Dunrobin,
Kinburn and
Constance Bay. Another rural area (south of
Bells Corners, west of
the 416 and south of Barnsdale Road) was added to the riding from the
Nepean riding. In the east, parts of
Orléans and
Glengarry—Prescott—Russell 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. And finally, the
Findlay Creek area was reallocated to
Ottawa South.
