It works well when everyone is on the same page, however once we get politicians involved (i.e. with transit planning) we introduce an immense risk since plans seem to change at City Hall and Queen's Park depending on which way the political winds blow. An example would be the proposed York City Centre. Back during the days of the Eglinton Subway, York planned a downtown core in the Mount Dennis area, but that died when the subway was cancelled. Imagine if that had continued but the Subway cancelled. We would have a struggling Sub-Centre without the prospect of transit for 30 years (from the 90's until the Crosstown Opening in 2021).
