The city itself, and the reason there is no separate Ottawa page: this whole site is it.
West end, roughly 20 km out, and the most age-layered area on the list: Beaverbrook's first street was laid in 1964.
South-west and outside the Greenbelt. Two tornadoes crossed it on 13 July 2023, both rated EF1 by the Northern Tornadoes Project.
East end, about 16 km out and cut off from urban Ottawa by the Greenbelt. Roughly a third of residents have French as a mother tongue.
A former city, not a neighbourhood: a township from 1792, a city from 1978, gone into Ottawa in 2001. The name survives on the mail.
Also a former city rather than one community, at 298.5 km2 and 150,012 people for the old boundary in 2021.
A separate city in Quebec, created 1 January 2002. Three major Ottawa River floods in seven years, with 3,800 homes and cottages affected in 2019 alone.
Its own city ward south and west of Kanata, with subdivisions that date cleanly by decade from Fringewood to Potter's Key.
A village inside Ottawa, laid out in 1817. Water comes from wells while wastewater is piped out of the village entirely.
A village on the Rideau about 25 km south. The core is on central water and wastewater, the estate lots west of Mud Creek are not.
South Ottawa, 19 km from Parliament Hill, with effectively no pre-2000 housing, so lead-safe questions do not arise here.
A rural village 32 km south, the furthest out we go. On half-acre to two-acre lots the constraint is the septic bed, not access.
South Ottawa, 18 km out and settled in 1996. Full municipal water and sewer throughout, and one c.1950 pocket the suburb grew around.
A village in the Carp River valley 33 km northwest, its own boundary set in 1979. Rural servicing, so wells and septic beds decide where a truck can park.
Urban since it incorporated as a town in 1913, about 4 km east of Parliament Hill. Small lots and narrow streets, which is an access problem before it is a hauling one.
2.41 km2 of former Gloucester, ringed on every side by NCC Greenbelt and old Defence Proving Grounds land. A suburban island with no adjoining subdivisions.
A designated village 25 km east at Colonial and Trim. Cumberland Township, then the City of Cumberland from 1999, then Ottawa from 2001, so no out-of-town surcharge applies.
Three things share the name: the village on the south bank of the Ottawa River 24 km east, the former township that also held Navan, Sarsfield and Vars, and the ward.
The entire village is a Heritage Conservation District under Part V of the Ontario Heritage Act, so what may be moved, stored or skipped on a property is governed differently here.
The original residential city south of Parliament Hill, on full municipal services. Two Part V heritage districts sit inside it: Minto Park from 1988 and Centretown from 1997.
Inside the city since the 1889 annexation to the Rideau Canal. Two Part V heritage districts, and lots deep enough that most of the work is the walk from the door to the truck.
Annexed from Nepean Township around 1949 to 1950, when Nepean lost 7,420 acres including Westboro Beach. Sources disagree on when the police village began, so no start year is printed.
The incorporated Village of Hintonburg from 1893 until the city took it in 1907. At 1.215 km2 the smallest area on this list, and heritage status is per address, not district-wide.
A pocket between the Rideau Canal and the Rideau River, the Police Village of Rideauville until annexation on 16 December 1907. Two waterways means two flood exposures.
Annexed from Gloucester Township in 1950, when Gloucester lost about 14,000 acres including Billings Bridge. Fully serviced urban land, so no wells or septic to work around.
