The NCC delivered a presentation on the western STO expansion, specifically the crossing and entry into Ottawa. They prefer the Wellington surface option however they also do support the Sparks tunnel. You can find the presentation attached below.

Honestly, the more I think about it, the more I like the idea of Wellington being pedestrianized and on-street tramway, as long as it is properly integrated with the Confederation line. Even if it means digging an underground tunnel to access Lyon or something like that. If the long-term goal is really to loop back to Gatineau, the tunnel is just a barrier to actually doing anything.

Of course, elected officials in Ottawa are gonna do anything they can to keep Wellington open to cars, even though it makes no sense as all this traffic can be easily diverted south towards the former transitway...
