I have no faith that better service can be expected from an Ontario-Quebec corridor joint venture than the Feds currently provide. Any such venture is going to be predicated on agreement by both provinces to any change or increase requiring subsidy and on one side or another an excuse to reject or delay or water down that improvement will be all too easy to find.
The example I have where supply has been plainly running behind demand for decades is the Dublin-Belfast passenger railway service, which has locomotives which have to be 50pc owned by each side and where the northern side has suffered from dysfunctional government for decades. I won’t say there have been not been improvements, but nowhere near what could have been done.
Instead, I would pick up VIA HQ and relocate it to Ottawa, so that management can be closer to Transport Canada and to federal MPs. To my mind, Ottawa has been the pivot around which the YDS era growth occurred, and with some capital investment into passing track, Ottawa and Fallowfield platforms, >100mph on VIA owned exurban track, and negotiating higher throughput at Smiths Falls, Coteau and De Beaujeu, the Corridor money machine could really start dinging
