You seem to miss the disconnect. You admit that the subway system is already crumbling, yet believe somehow there is a significant amount of money to be spent on expansion. You admit our system is pathetically small, but shun the biggest improvement in a long time as not good enough despite the replacement being a waste of money for less. Lastly you ignore the fact that some cities much smaller than Toronto have bigger networks in Toronto and those networks started with pre-metro systems. Transit City would make the system more efficient, lower energy costs, lower driver costs, increased reliability, etc. Transit City wasn't meant to be the end state, it was meant to be an improvement to the status quo which is tacking a few stations on existing lines every 10 years.
