I have no clue about how far below ground the current tunnel is, or what emergengy exits it has (beyond knowing that Mount Royal is pretty tall in pictures!). Still, I would think the cost of a new bore might be lower, based on what tunnelling Toronto’s subways and LRT are said to cost. Of course, even a $2B tunnel would be hard to sell.
It is almost impossible to exaggerate the monumental scale in financial cost and paralysis which building a second tunnel under the Mont-Royal would cause and that is much less so because of the mountain itself than by the layers of transportation infrastructure which crisscross the ground underneath and around the Gare Centrale:
At first sight, it may not look that difficult because the existing tunnel actually doesn't run under the center of McGill College Avenue but under the center of its northeastern half, if you compare this photo...

...with this Google Street View image of what is today the intersection of McGill Collegue and Cathcart:
The tunnel therefore runs roughly underneath the parked cars next to the yellow line (and I actually happen to know the building on the right very well, as it was right in the back of my first desk at the VIA HQ), which should allow the construction of a second tunnel underneath the other (southwestern) half of McGill College Avenue, right? Well, there are just two slight problems and both are caused by the REM project:
First, there is the slight complication that there will be a REM station at McGill Metro Station (and thus only a few hundred meters up McGill College Avenue), which will naturally extend well beyond the horizontal limits of the existing tunnel ...

...and will leave very little space to fit a second tunnel between the Place Montreal Trust and the Eaton Center:

Secondly, staying southwest of the existing tunnel means that you would arrive onto tracks 7 and 8, which are reserved for storage by REM trains (which is the smallest issue), require a station entry on the western side (which will be expensive, but not impossible):

The bigger problem will be, however, to exit the Gare Centrale on its eastern side, as it is completely covered by three separate massive building (Place Ville-Marie, the Queen Elisabeth Hotel and the Place Bonaventure) and would require the removal of a significant number of supporting columns:

And even if you find a way out of Gare Centrale, you now would need to find a way to avoid the REM ROW (the lighter gray or more Southern pair of tracks), the ramp up to the parking levels of Place Bonaventure and the Edifice Rodier and New City Gas, with the latter two being listed buildings
which already forced the CDPQ to completely replan the routing of this segment of the REM:

So what about going above or below the current ROW? Above, forget it, as there are buildings on top of Gare Centrale and the green line above the existing Mont-Royal tunnel (refer to the picture of McGill station further above).
As for going below the current ROW, there is the slight problem that the Autoroute Ville-Marie (think of the Gradiner Highway, but well hidden in a tunnel) happens to be the most complex just at the eastern end of Gare Centrale:

Just to give you an idea of how deep you would have to dig to avoid the Ville-Marie and Viger tunnel complex, it reaches until 42 meters under street level only 200 meters north of where VIA passengers leaving Gare Centrale view the daylight for the first time (exact location

And we haven't even touched the question of where and how you want to build a full-size intercity terminal railway station anywhere underground and near Gare Centrale...
This is intriguing and raises a few questions.
1) Were the travel times provided in the slide presentation the worst case scenario (for lack of a better term)? Or can they get even worse for the Havelock sub?
2) How much confidence do you folks have in that cost estimate? Have your outside consultants also helped with cost estimation? I think most are skeptical given past estimates ($1.5 billion for GO service to Peterborough). So it might be tough to digest $4.4 billion for such a long and complex corridor?
3) Do you have an internal list of "nice to haves" that you can show your investors? Essentially a list of where investment produces the greatest performance returns?
4) Are you analysing markets for commuter potential? I look at Ottawa-Montreal and Montreal-Quebec and see some real potential from commuters as HFR creates a market.
I'm currently too tangentially involved in the HFR project to answer these questions and even if I was more closely involved, I would probably not feel compelled to volunteer any answers. All I can say is that the cost and travel time estimates have been of course provided by well-reputed engineering companies and that Ottawa-Montreal, Trois-Rivieres-Montreal or Peterborough-Toronto are without any doubt interesting commuter markets. And yes, the desires are always endless: continuous double-tracking would be an equally obvious and costly wish...
The CIB pitch sounded much more like a mortgage or GIC offering than a hands-on equity ownership: invest and this is the return. The test that the market would apply is simpler - is this going to run in the black, and will the business deliver the promised (fixed) return? So long as the “dividend” is paid every quarter, the investment is a good one. Presumably if the venture does even better, the incremental return goes to the Bank, and thus indirectly to Canada. The problem that poses is - those decisions about whether to do 125 instead of 110 are made through the federal bureaucracy, and inevitably, its politicians. That doesn’t inspire confidence.
The “what the investor deems best” approach that @UrbanSky describes might appeal more to a Branson or Buffett than a Gates...it implies the investor has an interest and familiarity with running a railway, and the variables and levers that can be adjusted. The investor would make those decisions in a more informed manner and reap the added return. I hope the investment is being structured in that way.

Again, I'm too tangentially involved in the HFR to know who is calling the shots on the final design, but my suspicion would be that TC tries to micro-manage and downsize everything, while the CIB tries all they can to get their potential investors involved into these discussions (rather than having the bureaucrats at TC second-guess their needs and desires)...
