I do agree that we're likely to end up closer to $12B than $6B if we want anything that is both upgradable and can be better than services today (I think people forget that VIA does have express services that do T-O in 4 hrs and T-M in 4.5 hrs).
Not really. Speed drives grade separation requirements. For anything below 200 kph, they can just build protected crossings. Above that it has to all be grade separated. Not cheap.

True, there are a ton of grade crossings and that does put a hard limit on speed.
I (perhaps naively) hope that many, perhaps 2/3, of those can be just closed leaving the rest to cross the railway. I will also make a semi-baseless prediction that as the project progresses, there will be a push to grade separate many of the remaining ones from various parties.
So I wouldn't be surprised if the final HFR product is closer to HSR than it will be to the current corridor line. 200km/h already just about makes the grade by some definitions - the original Shinkansen ran at that speed, and sections of the UK's ECML and WCML are classified as such by some.
I've said it before, but it gets me thinking of how the Green Line in Calgary developed. The original vision was for a $4.5B line crossing all of Calgary using cheap surface LRT technology. That was just a guess, but it was presented to the public as real fact. Then as they did the work, it transpired that there was no way of actually building that cheap surface LRT, it needed a downtown tunnel, and there was lots of grade separation elsewhere. The $4.5B for 45km went out the window, and what is being produced is close to a metro in terms of cost and grade separation, but still using stupid streetcar vehicles.
The same will happen with HFR. It already happened in the Tuesday announcement with the addition of electrification. Once they do more detailed work, it'll turn out that to do certain parts of the line properly it'll require spending more money than the original bare-bones proposal laid out, and certain interest groups will want to change the project in ways that possibly make it better, but definitely make it more expensive. This will be hand-waved away later by politicians and perhaps it's all worth it in the end, but it is entirely predictable.
