While riding the GO today, I noticed that there was a construction crew working on the UP platform at Mount Dennis. You’d have thought that with all the delays to Crosstown, it would be finished by now ! While some of the construction fencing is down, there were still plenty of toolboxes and piles of materials on hand.
It will be pretty, well, something if Crosstown finally opens but the GO/UP station isn’t ready.

The existing UP platforms have a 16 km/h speed limit for UP trains, presumably due to the low clearance between the permanently-affixed gap fillers and the platform. (There is no speed restriction for GO or Via rolling stock). It's possible they deliberately postponed installing the platform edges at Mount Dennis until the last possible moment, to avoid forcing UP trains to slow to 16 km/h at a station they don't stop at.
