Point taken on some of the details, but I don't find it at all a bad thing for it to look geometric. The ROM also came to mind for me; obviously it's not as dramatic (they weren't going to hire Daniel Libeskind for this one) but I think the contrast is the point.
The more important principle for me is that, even though it's no longer functioning as a religious building, people have taken the effort to maintain it, update it to modern needs (e.g. accessibility), and repurpose it. That's nothing new, but it feels all too rare in Edmonton. Contrast the rectory next to the cathedral that just got torn down...
