I'm no fan of the provincial liberals but I actually don't mind at all.  There are many great transit systems in this world that are not "profitable".  I think we should look at it more as a public good.  Are roads "profitable"?  Are parks "profitable"?  There are many externalities that can't be quantified.  A city the size of Toronto NEEDS to be connected to its airport.  I know a lot of people will have a hard time getting beyond the politicizing but we should be looking at the bigger picture here.
