There's much complaints from residents on Sherbrooke St. about the elevated structure also.

Seems that there will be a station or two underground downtown for the REM B (de l'Est) line. A short tunnel to Gare Centrale. What I like the most of the proposal is that thereotically the REM could be extended further West, which would have been difficult with an aerial structure.
REM de l'Est | Un nouveau tunnel court à l’étude au centre-ville
Un nouveau scénario « alternatif » d’insertion du Réseau express métropolitain (REM) de l’Est au centre-ville de Montréal, qui comprend un court tunnel de 500 mètres, une arrière-gare ainsi qu’une ou deux stations souterraines, a été présenté par CDPQ Infra au cours des dernières semaines, a...www.lapresse.ca
A couple of excerpts, crudely translated to English by Google:

This is still a very, very minimal amount of effort in making the proposed line blend in better with the streetscape.

How so? We have seen nothing so far from the architectural firms. It's planned to be shown in December.

I'm just going off the rough english translation of what was mentioned in the LaPress article. Really the only thing that's changed is a portal to have an underground transfer, but it will still be essentially all above ground if the article is correct.

Being aerial doesn't imply no architectural integration.

I'm referencing the opinion that I and many others hold/are concerned; regardless of measures taken, having it above ground will be visually obtrusive and unappealing compared to below ground.

Its mere existence above ground does not inherently make it unappealing and obtrusive. There are many examples of great-looking elevated guideways that have already been shared on this thread.
The fund already said they don't plan to have it look like the ones on REM1. We will have to see what the show is in December.

CDPQi provided an update for the REM de l'Est project today:

This is the new plan, with the 500m downtown tunnel and an underground terminal station:
Studies reveal that a longer tunnel would be possible, but it's quite risky to bore a 9.4 meter diameter tunnel just 3.9m under the orange line.
CDPQi is adamant that no company would want to bid to undertake a project with such a risky segment.
REM de l’Est: project update
CDPQ Infra issued an update on the REM de l’Est project, providing a progress report and publishing two separate technical reports with analyses of underground route scenarios.

What are those boxes to the left of the station? Are they in any way a problem if Montreal ever wants to extend this line westwards?CDPQi provided an update for the REM de l'Est project today:

It's a pretty subjective opinion; many people reference the skytrain as an example. This isn't a fair comparison, as it is elevated in an almost exclusive suburban or industrial environment.

Foundations for the Place Ville-Marie - Central Station complex.
To help you understand: I just made an overlay of the REM station over a Place Ville Marie plan.
As you can see, the Central Station platforms are right behind the end of the REM de l'Est tunnel.
Therefore a westwards expansion appears to be absolutely impossible.

Almost 4 metres clearance seems huge compared to the clearances that the TBMs for Crossrail did - less than a metre in places - without even closing the other tube line in London - at least at Tottenham Court Road.
Though looking at the illustration, I'm not sure why they couldn't build the portal near Labelle, with cut and cover between there and Sanguinet to simply and safely work around the existing tunnels. This would also allow for construction of a station between those locations, connecting to Metro Berri.
