Even Canpa detours beside, some of those runs appear to be there purely to pad the figures, and they will not only run at a large loss, but will most likely complicate dispatch by using what is now pad time in the schedules that was flexibly slotted prior, but now must meet a rigid schedule. The runs from Union to Mimico look exactly like that. No conceivable gain, and lots of potential pitfall if a VIA slot is running late, let alone other GO ones.
I'll be surprised if with the present signalling and control system, that the 'level of incompetence' isn't reached with this exercise.
