Though you don't need 20+ streetcars on many lines. The AM peak fleet requirements that TTC published a couple of years ago was (I believe):60 Streetcars is not bad. That will put the fleet at 264 if I am not mistaken so around 24 streetcars on each line. 22 if they want to bring back the 502.
501 - 41
503 - 17 (includes 502, though long-term plan is to run 503 only from Kingston Road to Dufferin Loop)
504 - 45
505 - 27
506 - 30
508 - 5
509 - 8
510 - 14
511 - 11
512 - 20
For a total of 218 cars. With a 20% spare ratio that's 262 cars.
Which means further cars will be necessary for Waterfront East, etc.
