I think that's true. I believe the Canada Line does enter the stations a lot slower compared to Skytrain. I think it has to do with depending on the friction of the brakes to actually stop the train. If it was moving faster, the chances of overshooting the stop point would be greater, especially in cold or wet conditions. The C-line trains do seem capable of accelerating and decelerating very quickly, but it's probably less reliable to be 100% consistent compared to Skytrain.
I think the LIM engine has that built in accuracy and reliability. C-Line trains depend on the Coefficient of friction of the track, wheels, and brakes, which can fluctuate. Skytrain LIM doesn't have such an external modifier that is variable (except maybe distance between the parts, which in a rail system is very constant and minimal, and the Electromagnetic field of the LIM actually lifts the train off the rails to achieve equilibrium).
