Because Metrolinx is paying for the design, and the design influences and is influenced by the headways. Thus, Metrolinx should have a good idea of what standard they need to build to and willing to share the info, while the TTC has more at stake in telling the public a figure that might not be realised.
Well I'm no expert but I'd have thought offpeak frequency was a purely operational decision. You design for peak loads and then decide how many operators to pay for in the middle of the day, right?
I'll leave it to someone else to explain how they could be contemplating peak hour headways that are slower than Sheppard!
