Meanwhile in the Fantasy Map thread re: streetcar tunnel extension
This requires digging under Union Station and the GO Tracks again to get proper elevation. Remember the loop and the subway tracks are on the same level right now. Extending the tunnel to City hall would cost over $1B for sure.
It can't be emphasized enough how challenging it is to tunnel under Union Station. There's a ton of infrastructure that has to be engineered around, including a dozen bridge structures, many of whom are carrying active rail lines. This is in addition to whatever other infrastructure is there, as perhaps poor soil conditions. I don't think we'll be seeing a new tunnel under Union Station in our lifetimes, and certainly not for a streetcar.
