I continue to think that "Transit City" is totally inadequate for a city the size of Toronto. See for example Singapore, a city-state with a land area roughly similar to the City of Toronto (ignoring the 905). In 1980 its population was 2.41 million people (source: Wolfram Alpha), roughly comparable to the City of Toronto now. It originally planned to build a "rapid bus" system, but it decided to build a subway system because it thought the bus system would be inadequate, which turned out to be a great success. Its population is now 4.84 million people, the subway system has turned out to be a great success, and it is building more lines.
