given the mention of 200km/h, I suspect we are looking at a primarily new alignment between Peterborough and Smith Falls. The area is too curvy as is to really be useable, and the isolated location means a grade separated 200km/h line wouldn't be too much additional in cost over a 177km/h line as minimal grade separations are required.
That would inch up construction costs closer to that $6-12 billion number and would allow trains to clear Toronto-Ottawa much quicker.
If you could get Fallowfield-Peterborough mostly into 200km/h territory, you could theoretically clear that stretch in 1:30 or so, giving 1:30 for Peterborough through Toronto and access into Ottawa.
That theory also fits with a timeline that runs to 2030. It would take that extra time to build a new alignment.
I would feel a lot better with that plan ( even though it costs more) than with settling for whatever speed can be wrung out of the existing alignment. Do it right from the beginning.
