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:
Toronto 521.7 million
[466.7 million TTC + 55 million GO]
TTC
GO
Montreal 382.5 million
STM
Vancouver 179 million
Translink
Calgary 95.3 million
Calgary Transit
So obviously we're doing better when it comes to transit than just the rail stats show.
True (annual) ridership per capita:
Montreal: 106
Toronto: 95
Calgary: 87
Vancouver: 85
