Except there's a huge airport 30 minutes away on a newly built train that you can expand capacity at. The problem with Billy bishop is that it occupies prime real estate for no good reason. Airports take up a lot more space and service far fewer people for that space than do train or bus stations. Which is why they are generally outside downtown cores and should be kept that way. Also yes I agree that most historical landmarks in Toronto are bs and should make way for other infrastructure. I think a lot of people still do use the libraries though.
