Please show me the business-case scenario where HSR to Waterloo doesn't have a worse benefit-cost ratio than the UPX train has today.
And what can HSR do for the Waterloo region that GO-RER isn't already promising? Shaving off 20 minutes of trip travel time? With what level of frequency and how many billions of dollars spent?
If we are talking about Toronto-Montreal HSR, I'd welcome an advisory panel. No other region in the world is spending billions in HSR to connect cities the size of Waterloo, London and Windsor, unless they were intermediate stops between a city of similar size to Toronto.
The newest highspeed rail line in the world is going to open in Morocco by the end of this year, linking Casablanca (metro area 5m) and Tangier (metro area 3m) with the capital Rabat in between (metro area 4m). That is 350km of rail to connect those urban centres, which is a good comparison since Toronto to Windsor is also 350km of rail. In comparison, neither Windsor or London have even 500k people.
Here is the other good piece of news. That 350km Moroccan high speed rail project is going to have an operating speed of 320km/h. Meanwhile, what we are proposing as HSR for Toronto to Windsor clocks in at 250km/h. I am not sure if that even qualifies as HSR.
