So I guess according to Wikipedia it's not a white elephant but that doesn't change the fact that public money is being built for a non-public transit system that will not make a dent in Torontonians long commute including to the airport.
The Blue 22 version was private. This current iteration is public. I'm not sure if it has a profit mandate or if it can operate at the same subsidy rate as a GO route, but it certainly is not privately owned.
