With the exception of the more conservative rural western and southern parts, the former Region of Ottawa-Carleton which became the new City of Ottawa in 2001, has traditionally been a Liberal heartland.
A high proportion of Francophones and civil servants had made ridings such as Ottawa—Vanier among the safest Liberal seats in the country, however, now there are probably only two safe Liberal seats in Ottawa - Ottawa South and Ottawa—Vanier.
The NDP's only historical victory in the area, Ottawa Centre in 1984, was repeated in 2004, as their popular former leader Ed Broadbent was elected.
They held them until 2015, when the massive Liberal wave that swept through Ontario resulted in the Conservatives being reduced to only one seat.
The Liberals even managed to win Kanata-Carleton, essentially the Ottawa portion of Carleton-Mississippi Mills, with the help of star candidate and retired Air Force officer Karen McCrimmon.
