Look at density maps like this one based on the 2021 census
https://censusmapper.ca/#13/45.3972/-75.7257 really show how strangely distributed density is in Ottawa too. There are some quite central areas like the Glebe, Old Ottawa East, and Westboro where the current density is roughly the same as Orleans and Barrhaven, which complicates things. Most of central Ottawa outside of Centretown, Lowertown, and parts of Vanier actually have similar densities to the suburbs. And then you have areas quite far out like Bayshore and Jasmine with higher densities than anywhere else in the city. At the other extreme you have other quite central areas like Rockliffe, Manor Park, and Rothwell Heights with densities equivalent to rural Ottawa.
