The Ottawa Valley is the valley of the Ottawa River, along the boundary between Eastern Ontario and the Outaouais, Quebec, Canada. The valley is the transition between the Saint Lawrence Lowlands and the Canadian Shield. Because of the surrounding shield, the valley is narrow at its western end and then becomes increasingly wide (mainly on the Ontario side of the river) as it progresses eastward. The underlying geophysical structure is the Ottawa-Bonnechere Graben. Approximately 1.3 million people reside in the valley (and along its tributaries), around 80% of whom reside in Ottawa. The total area of the Ottawa Valley is 2.4 million ha (6 million ac). The National Capital Region area has just over 1.4 million inhabitants in both provinces. Near the City of Ottawa, the Ottawa Valley merges with the St. Lawrence Valley to the south to create a delta of flat farmland stretching unbroken from the Ottawa River to the Saint Lawrence River as far east as the island of Montreal, where the two rivers meet. The area is sometimes referred to as the "Lower Ottawa Valley," in contrast with the "Upper Ottawa Valley" west of Ottawa, but the name is not common, and most people think of the Ottawa Valley as only the upper portion. From west to east, communities in the Ottawa Valley include Mattawa, Deep River (with nearby Chalk River, the site of Canada's nuclear reactor program), Petawawa (a major Canadian military base), Pembroke (where Samuel de Champlain landed briefly), Fort Coulonge, Shawville, Renfrew, Quyon, Arnprior, Ottawa (the nation's capital), Rockland, L'Orignal, Hawkesbury, and Rigaud and Almonte, Round Lake Centre, Dacre, Douglas, Hyndford, Scotch Bush, Osceola and Barr Line.

MacLarens Landing is a community in West Carleton-March Ward in Ottawa, Ontario. The area's name is derived from James Maclaren, who opened a mill in nearby Buckingham, Quebec. Ontario MPP Jack MacLaren is a descendant and resides in the area.

Torbolton is a geographic township and former municipality that was originally part of Carleton County in eastern Ontario, Canada. Torbolton is located in the north-western part of the county, bordered to the southwest by Fitzroy Township, to the southeast by March Township and to the north by the Ottawa River. It includes the communities of Baskin's Beach, Buckham's Bay, Constance Bay, Dirleton, Kilmaurs, MacLarens, and Woodlawn. The township was established in 1821. Although white pine was harvested from the forests of this area from the beginning of the 19th century, the first permanent settler is believed to have been David MacLaren in the 1820s. In 1974, the township was amalgamated with Huntley and Fitzroy to form West Carleton. In 2001, West Carleton became part of the new city of Ottawa. Torbolton took its name from the village of Tarbolton in Ayrshire, Scotland. Lord Torbolton was one of the titles of Charles Lennox, 4th Duke of Richmond, who was Governor General of British North America from 1818 to 1819. According to the Canada 2016 Census, the Township had a population of 6,974. As of the Canada 2021 Census, this had increased to 7,000.

At that time, the ward was called West Carleton Ward. It consisted of the former West Carleton Township. In 2006, the boundaries were altered, and the ward was given its present name. Its southern border became Highway 7 and the Queensway and it lost some areas in the southeastern part of the ward. The ward also added the rural northern portion of the former city of Kanata. Its population in 2006 was 23,400 – the second least populated ward. Its area is 763 km², the largest city ward. It was represented by Eli El-Chantiry on Ottawa City Council from 2003 until 2022 when he retired. Clarke Kelly won the 2022 election to represent the ward. Following the 2020 Ottawa Ward boundary review, the ward lost small sections of territory in the South March area and north of Stittsville to accommodate proposed housing developments.
