Katimavik-Hazeldean is a neighbourhood in Kanata South Ward in the west end of Ottawa, Ontario, Canada. It is located in the former City of Kanata which amalgamated into Ottawa in 2001. It is located in south-central Kanata, bounded by Eagleson Road to the east, Hazeldean Road to the south, the Carp River to the west, and Highway 417 to the north.
According to the Canada 2011 Census, the total population of the neighbourhood was 12,088.
By 1866, Hazeldean was a small post village with a population of about 50, in the township of Goulbourn. The village contained one general store; one common school, with an average attendance of twenty-four pupils; and one church, used in common by the Church of England, Presbyterians, and Wesleyan Methodists.
Campeau Corporation started development of the Chimo Drive neighbourhood between Katimavik and Kakulu roads in the early-mid 1970s, based on the garden-city style implemented by Bill Teron in Beaverbrook on the opposite side of the highway. Numerous developers followed Campeau's lead, progressively developing the area west of Castlefrank Road and the area between Kakulu and Hazeldean roads (annexed to Kanata from Goulbourn Township) in a sympathetic style in the 1980s and early 1990s.
The area between Katimavik Road and the highway was intended to be part of the Kanata Town Centre and originally zoned for light commercial/industrial and later high-density residential. Much of that area was rezoned for medium-density residential, and a number of townhouse and detached-single developments were built on that land in the 1990s.
As in other parts of Kanata, most streets are named according to neighbourhood themes: In the northeast section, Arctic explorers; in the southeast section, Canadian broadcasters and entertainers; in the west section, Canadian inventors; and in the former Town Centre lands north of Katimavik Road, Ontario premiers and lieutenant governors. The community was named "Katimavik", in 1972 by 12 year old Kanata resident Corinne Friesen was the result of a local area contest. "Katimavik" means "Gathering Place".
