They've been testing speed control, which is a component of ATC, on Sheppard for years now... I guess they still haven't finished it?
SCS has nothing to do with ATC. It is simply an overlay of the existing wayside signal system that enforces speeds and signal indications, rather than just the permissiveness of the signal. And yes, it is active on the Sheppard Line.
