More seriously, what's the acceleration/deceleration time for the current GO rolling stock? How much time would we save with all new rolling stock?
I ran some number with our existing rolling stock (50 tonne bi-level coaches and a 130 tonne, 2700 kW locomotive). It looks like a 10 coach train should be able to accelerate to 160 km/h in about 100 seconds, and decelerate in 80. A 6 coach train only needs 70 seconds to accelerate and 60 to decelerate.
So, that's about two minutes extra per station, for a 10-car train. (Are the FLIRT numbers for a similar 10x 50t cars?) About 18 minutes for the current set of stations, on top of a super express service with no stops. 1h15 from Kitchener to Union Station -- I would personally be quite happy with that.
If the Stadler FLIRT specs are for the electrified version, the upgrade price tag would be substantial.
