Based on ridership alone I don't think it arguable at all, Calgary's is the most successful LRT system, bar none.

If predictions hold edmonton's ridership per km or per station will be on par with calgary this year, but their much larger system means that they will still have more than twice the ridership. I guess that the only failures of Ctrain are it's slow and disruptive movement downtown, and overcrowding, but that's only a failure because of their overall success: if the had ridership on the same order as a US city, there wouldn't be problems.
