I would expect that if there is any major deficiency during either of those testing phases, that phase of the process restarts.

I would expect "major" defiiciency means one that requires some portion of the line (or even a platform) has to be ripped out and replaced, with the change being significant enough to have to start the tests again..
Such a change should be major enough that it would be in the news, and we would know about it, as opposed to reasons for delays that are kept secret.
The problem is, we're talking about this using vague examples and unnamed hypotheticals, and not even defining "major".

Why would this extreme scenario be the case?

When the TTC is stress testing new streetcars, they are required to rack up 600 km before being given the green light to enter service. Any major problems can reset the counter to 0. I would assume there is a version of this problem that can be extrapolated to a whole line without the line actually needing to be ripped up, in the same way a new streetcar doesn't need to be scrapped and a replacement built when it suffers a setback that resets the km counter to zero.

As dowlingm noted, a major software upgrade could easily fit the bill here. As could any changes to the infrastructure, such as the overhead wires, switch mechanisms, etc.

That depends on what the problem or deficiency is.

When the TTC has done its simulated service testing for any of its previous line openings, any failure was first deemed a way to review the procedures for repair and returning to service. A review is then done to see what the root cause of the failure was, whether it is deemed detrimental to the schedule for actual revenue service to be started, and the likelihood of it happening again. I don't know of too many failures that they've had that have caused them to push back the launch of revenue service - but yet in the past 30-plus years we have had revenue service launches with faulty escalators, wonky fire alarms and other incomplete or in-operational systems that, while are necessary in the grand schemes of things, are not absolutely essential for revenue service to begin on a certain date.

does anyone kwon if the 14 day trial run is completed?

The 14 day trial has turned into a 2 month and counting "very intensive trial running period" according to the metrolinx CEO.

I think at this point they are just waiting for the maintenance schedule things to get sorted out before giving the green light for RSD (which is scheduled to begin "in a few weeks"
😭 😭

What would be nice is if they had some sort of website detailing the steps to opening day in which it would say "you are here". Even better is if those steps were clearly explained in layman's terms so the general public understood what is going on.

Why not ask for a pony while we're wishing out loud? Metrolinx is where transparency and accountability go to die. And this is at least as true under the present provincial government as it ever was under the Liberals, if not more so. They share the same primary instinct: if you sense risk people might perceive you're not performing, take cover. Deny, distract, disparage, and just plain stonewall your way through another day.
 
I think the city of Toronto should list the tunnels for line 5 crosstown as a heritage site. See cities, all around the world have rail rapid transit but we are building something special here. A $10 billion project that has been under construction for over a decade and no one knows if and when it will open. So that’s something to market on for tourism and it’s part of our heritage at this point.

Indeed. Line 5 is getting pretty close to Amsterdam's North-South line [8 stations] which took 15 years from construction start to opening; delivery was 7 years late.

Oh, I know asking for something like that is asking for a miracle.
