Did they just remove the hill without stabilizing it?

They did take measures to stabilize it.
But they weren't the finished product measures.
Also, they didn't tarp the slope.

What they did here wasn't really egregious, bad outcome aside.
I'm somewhat harsh here, in part, because I very much dislike the design choices made in the first place; though I conceded my preferred option would have been materially more expensive.
Be that as it may.
I think the way in which this was phased was less than ideal; and tarping would have been highly desirable; and while one can't be certain, I think it likely those actions would have mitigated the risk of collapse.
In fairness, the entire slope project to this point is only around a six month timeline. Still, I think it could have been compressed.

My reaction when I saw the tweet was similar to @drum118 's - there's an awful lot of exposed rebar remaining for anyone to be celebrating victory. But I don't know enough about their construction logic - it may be that having the track bed laid lets them move on to other things or gives them mobility within the site. Even stretching the rail without actually laying it might be a big step forward depending on where the rail is now and how getting that done lets other things get advanced.
What struck me as much more indicative of progress is the notice about demobilization of the Caledonia station crane. That means a certain number of things have been completed.
As to the soil movement - what caught my eye is how more than one article/tweet used a photo of the underpinned Line 1 crossing in conjunction with the event. That took my breath away, until I read further and realised that the event wasn't connected to those crossings. The embankment movement is bad enough, but it's fixable and really not that big a delay. Any event that actually affected the crossings would be a much bigger deal. I thought the authors of those items were sensationalising, although only us sidewalk supervisors may have cared. Joe Public might not have ever noticed.

Sorry! Out of service. Use steps.

More like you will have to wait until the system to open in 2 years or so to use it, considering most Metrolinx projects have elevators opening months late after the project goes into service. Haven't heard or seen on Mount Dennis elevators considering that area been mostly done late last year. Keele should be next.

Expected. See what happened when back in 2018, six months after the Line 1 was extended.

Vaughan Metropolitan Centre Station has had a broken elevator ever since it opened 6 months ago (May 2018)
Don't think the surface stops have to worry about elevators. One reason to duplicate the elevators at the underground stations, in case of elevator failure.

This is the very reason I bitch about not having 2 elevators in place of one. Seen systems with 3. This folks are being screw over in the name of $$ or don't care at all.Expected. See what happened when back in 2018, six months after the Line 1 was extended.

As a note, they are planning to rebuilt Port Credit Centre platform elevator and that westbound platform will most likely be out of service for months and a rider will have to go to Clarkson to get a train westbound. If by bus to get to Clarkson, an extra 20-40 minute trip each way.

Having a centre platform with two elevators should have to designed from the first design steps. If one elevator is out, there should be another available (cross-fingers).

I found this article sort of sensationalized a really minor issue as the VMC station was completely accessible on opening day. The elevators in question were the elevators connecting the station with the VIVA station. The main elevator connecting the station to street level was operational the day the station opened so there was still an accessible route from the station to the VIVA station; albeit you had to cross an intersection. While annoying, this is sort of an issue when using any VIVA stop and the path through the tunnel to the VIVA station isn't much faster than going outside.
I think the bigger issue this article should have reported on is that every single station on the TYSSE extension (excl. Pioneer Village) only have a single elevator going down to the platform.

Sorry but just reading what you wrote and interpreting it differently, wonder if the rails could become a means for construction. No more concrete trucks and dump trucks clogging area roads during station construction. Use the rails to bring everything in and out. Materials, workers even. Build stations from the inside out. Maybe build the stations in consecutive order so we don't have a dozen construction sites lasting a decade. Have the rails first, and let's use them to our advantage.

How about they also shut down stairs that are next to the elevators that are broken. Why? To show the able bodied people that it isn't that simple.

I’m pretty sure that this will happen in later stages of construction. Certainly during TYSSE there were photos of TTC work vehicles in the tunnels well before commissioning.
I’m not sure the construction forces get much of a logistical benefit from the tunnels - by the time the tracks are laid, the really heavy material handling has already happened, and the big mechanical things (escalators, HVAC, etc) need to come in vertically from above, would not fit thru the tunnels. So long as the cranes have to be there anyways, might as well use them.
For the moment, even without rails in place, having the floor poured at least gives them a finished “floor” work surface.

Having things delivery by rail is more costly than using tower cranes. You need to allow time to transfer material to the train at X point, the time to get to X and the time to off loaded it. You will need Z equipment to off load X as well move it to Y if it can. You may need different type of rail equipment that can only be use for this type of work and will become scrap at the end of the day.
The floor bed for the rail allows the wall to be form and pour than coming back later to pour it after the wall is in place as well the platform. This station could be done different from the others for X reason or it been determine that this is the best option.
Tower cranes or any type of cranes is the best option for placing items into the hole at the end of the day.
