That's a hydro corridor ...
It doesn't cross the escarpment on a Hydro corridor, it crosses west of Fourth Line in Halton Hills north of 22nd Sideroad and south of Glen Lawson Road. It leaves the existing alignment, and cuts through a quarry, making a brand new cut through the escarpment through a bit that's been preserved in the quarry operation, before proceeding through another piece of the quarry, and slamming into a 20-metre rock face. It then proceeds magically through a field that is in the process of being licensed as a quarry, and will be by the time this starts. It's not physically possible, even IF the Niagara Escarpment Commission is going to okay a new cut through the escarpment. Which they are not.
I believe we've already discussed this in detail, when that presentation came out, in the thread for that project. Perhaps you should read it -

... but of course, you like to make judgements without knowing the intimate details.
Your a newbie who's been here only a few days, and clearly are very ignorant. It doesn't follow a hydro line. And I'm very familiar with the terrain. Far more familiar than the twit in the UK who drew the line, in complete ignorance to the rules governing the escarpment, not to mention all the wetlands it cuts through (which might be more feasible).
As to gradient, if that's what you're referring to, it's far less of a challenge than sharp radii on the existing RoW. Looked at how the TGV's align? Up and down hills instead of around them.
It's not so much the escarpment, but the number of shear rock faces it cuts through.
That alignment is impossible. The only chance of getting this approved environmentally is to follow the existing alignment, which then likely forces you through Acton. Which all but sterilizes the Guelph bypass
Well...ummm...I realize your grasp of matters political is not large, but she is the elected MPP of Guelph. And she wants to stay that way.
Good grief, she'll be long out to pasture by the time this opens - if not dead. She's already been the MP for 13 years, and she'll be about 70 for the next election. I know your grasp of matters political is not large, but there's no evidence that she wants to stay around much longer.
The VIA HFR proposal, to the best of my knowledge, never included any planning west of Toronto.
Maybe not the most recent ones, but go back to the VIA studies in the late 1980s. The commissioned many detailed studies of alignment all the way from Windsor to Quebec City. This followed on from the alignments studied in the late 1970s by a Queens University research institute, partially funded by VIA Rail.
