^Well Beltline actually has 4 different neighbourhoods for this reason, and the full name is "Beltline Communiites of Victoria and Connaught"
A lot of the inner city areas actually have this quality. Hillhurst-Sunnyside share a community association but are two neighbourhoods as well. There's Lower and Upper Mount Royal. Even the area that many might call collectively "downtown" (north of the CPR tracks, south of the river) is actually broken up into smaller areas of West End, Eau Claire, East Village and (proper name) Downtown.
