The concern of the people I talked to in the Cathedral area was that they wanted to make sure their association was kept whole because they have a very active association. Right now, as an example, they have a bit of a dispute with the provincial government on a proposed school closure. I understand they're lobbying the provincial government very hard, so they wouldn't want to see their associated split in any fashion. This maintains their community identity.
All it means is that they would be voting in a different riding, but nothing else changes.
