Central Ottawa
The pre-war city inside the canal and the Queensway: Centretown, the ByWard Market, Sandy Hill and the Glebe. Walkable, expensive per square foot, and almost entirely built before 1960.

Centretown is the residential half of downtown and the densest square kilometre in the city; the ByWard Market and Lowertown are the blocks Colonel By laid out in 1826, and still the only district where the street life outlasts the working day; Sandy Hill holds the University of Ottawa and, on the streets around it, most of the city's embassies; the Glebe is Bank Street between the canal and Dow's Lake, the one inner-city high street that never lost its independent shops.
This is where Line 1 actually behaves like a subway (underground from Rideau to Pimisi) and it is the only part of Ottawa where not owning a car is a normal choice rather than an eccentric one. Three things to check before you commit: whether the building is pre-1960, because the older stock is where the knob-and-tube and the galvanized plumbing are; whether it sits in a heritage conservation district, several of which run through these blocks and constrain what you may do to a façade; and, for anything near the canal or the Rideau, the overland-water endorsement, which the 2017 and 2019 floods made both more expensive and harder to get.
