Okay, so I've taken the map of the study area, and overlaid the boundaries of the various chapters of NIMBY International:
Left to right, the community associations are...
Blue - McKellar Park, Hampton-Iona, Hintonburg, Centretown**, New Edinburgh*
Red - Westboro, Wellington Village, Glebe, Lowertown
Yellow - Champlain Park, Civic Hospital, Old Ottawa South, [Action] Sandy Hill
Green - Westboro Beach, Dalhousie**, Old Ottawa East*
Where streets are used to define the CAs, unless directed otherwise, I project those street lines into the rivers where appropriate.
Note a couple of potentially CA-free zones in the west end; the residential area just east of Tunney's, and a vague no-man's land just south of Westboro Transitway station that isn't included in any of the CA boundary descriptions.
Not shown: Island Park Community Association. The neighbouring CA boundary descriptions use Island Park as the dividing line. The Island Park CA is kinda like the west end's version of Andorra.
Kitchisippi Ward is home to at minimum nine Community Associations. Now I know why I call it Bitchissippi.

* There is some vagueness in the self-appointed boundary descriptions for these community associations. In the case of New Edinburgh, it doesn't matter, since it only affects an unpopulated area of Rockcliffe Park the park. Old Ottawa East is a bit more difficult of a case; I've just used the boundaries of the neighbouring CAs to define it by subtraction. Sure would be good if all the CAs would publish their constitutions or by-laws.
** There's a two long-block strip claimed by both Dalhousie and Centretown, between Bronson and Bay. Rumour has it this territorial dispute will be settled by a jello wrestling match between CAM and ED. Also, Dalhousie's self-described southern and eastern boundaries don't actually meet, setting up another potential brutal turf war with the blue-hairs in the Glebe.
