Barrhaven is a suburb of Ottawa, Ontario, Canada. It is located about southwest of the city's downtown core. Prior to amalgamation with Ottawa in 2001, Barrhaven was part of the City of Nepean. Its population as of the Canada 2021 Census was 103,234. Geography Barrhaven is approximately bounded to the north by the Greenbelt, to the east by the Rideau River, to the west by Highway 416, and to the south by the new Half Moon Bay development along Cambrian Road south of the Jock River. The area is diagonally bisected by CN rail tracks. Barrhaven is surrounded by rural areas and farmland, with the exception of the growing Riverside South area across the Rideau River. Directly south of Barrhaven is Manotick, a commuter town of the city. Barrhaven is divided into several areas: Barrhaven proper or Old Barrhaven is the westernmost part of the neighbourhood, lying between Cedarview Road and Greenbank Road. New residential development is expanding the west side of Old Barrhaven between Cedarview and Strandherd Drive. Also included in this area is a triangle of land east of Greenbank between Fallowfield Road and the railway tracks known as Knollsbrook or The Triangle. South of this is the area known as Longfields, which stretches south to Strandherd and east to Woodroffe Avenue. Sandwiched between the railway tracks, Jockvale Road, Greenbank and Strandherd is the neighbourhood of Barrhaven on the Green. East of Woodroffe, next to the Rideau River, is the neighbourhood of Davidson Heights. South of Strandherd and east of Greenbank is a new community known as Chapman Mills. As Prince of Wales Drive approaches Jockvale, there is a thriving community known as Stonebridge that is located beside the Stonebridge Golf & Country Club. History The Barrhaven area was long inhabited by First Nations peoples, and the modern Jockvale Road follows an ancient path that was originally a trail through the wilderness. In the 19th century the area became populated by European farmers as the area was divided into a number of rural homesteads. The old Barrhaven School House located at Jockvale and Strandherd was in built in 1906. Today, the school stands as a historic site. In 1911, the Canadian Northern Railway built a rail line from Ottawa to Toronto through the area. Fast passenger service was offered for many years from Fallowfield Station (near the intersection of Strandherd Dr and Cedarview Rd) to Ottawa and beyond
