I would rather see a comparison of the entire transit system, including buses, etc. That would be a more complete picture of a city's success in terms of getting people out of their cars.
For example, the annual ridership for the entire transit system in 2008:
[466.7 million TTC + 55 million GO]
So obviously we're doing better when it comes to transit than just the rail stats show.
True (annual) ridership per capita
