While I don't know the economics behind this specific building, I think it's realistic to assume that it is probably being built for economic reasons and not because Dalton McGuinty is a skyscraper geek like us who just wants to see another really cool, tall building in downtown Toronto. Many people have already suggested reasons for why a building like this may cost the government less money in the long run. For all we know its construction may actually be part of the plan to reduce the deficit over the long term. Again, I can't prove that this is the case, but nor have you proven that it's being built for the sake of having a cool new building, or for patronage, or whatever else you are suggesting. Until one of us offers solid evidence one way or the other, it's a matter of deciding which explanation is more reasonable rather than jumping to conclusions.
