I doubt that a suburban/GTA section would get enough attention on this forum, it's "UrbanToronto" after all, but coming from the far suburbs myself I think that these are areas that deserve their share of respect and monitoring; most of the GTA suburbs have a collection of high-rises, mini downtowns, and bus and GO transit that most American suburbs don't come close to having.
Recently for example a forumer made a thread about the Burlington waterfront in the Projects/Construction thread. Although nothing comparable to Toronto projects of course, I felt that such rare and almost never-visited threads do deserve a small slice of attention.
And lastly, I think forumers such as AreBe who bring an alternative set of views only serve to diversify things up, it's not like one forumer will end the pro-urban stance of this forum.
