Why does Toronto have more "street-based" neighbourhoods than other Canadian cities?

[MonkeyRonin]

To add one more thought: the City of Toronto's "official" neighbourhoods are mostly quite small, and tend to treat the commercial thoroughfares as borders rather than as the "heart" of each community. They exist on a map, but otherwise feel contrived and unnatural to how these neighbourhoods are actually experienced on the ground. As such, most of these names just never really took off amongst the people who live there.

In comparison, Vancouver's defined neighbourhoods and Montreal's boroughs are larger, more historically consistent, and do a better job of corresponding to the "feel" of different parts of the city.
