Yes the whole area was designed more than a decade ago when they were planning the Georgetown South expansion project.Still the city'problem I'd think. But surely a concept to deal with the road has been in place for decades. You'd never ddesign it like this these days.
See this post:
The quad track segment that they built last year is from just east of Islington to just south of Weston Station.
The segment west of Islington will be part of a completely separate project which involves demolishing Etobicoke North station and realigning the tracks to use the new tunnels. Under Islington the plan is to use the space under road overpass to the south of the southern support pillars.
Extract from Metrolinx OnCorridor Public Information Centre #3 Draft conceptual design roll plans, November 2020:

Got it, looks like they'll build a new retaining wall and put it south of the columns...a mirror of where the road is on the other side. Explains why the deck won't be impacted.

And this post:
The existing tunnel has a speed restriction due to low clearance. Reducing it to 2 tracks will eliminate the speed restriction.
There is not enough space for 4 tracks under Islington with the existing grading. They need to build a retaining wall on the south side of the underpass to fit the south track under the existing structure.
