Ask yourself this question, would a family of 4, on a weekend trip to Montreal from Toronto, take a the (fast) train or enjoy the flexibility of their car?
There is no simple answer to this one. As a parent of a family of 4, I can say that the car allows a certain flexibility especially around bringing teddy bears and amusements for the trip, without the risk of leaving any behind on the train. And bringing the family pet along. And having mobility at the other end of the drive.
However....amusing two youngsters on a long drive can be, well, tiring. And the drive itself is definitely harder on the parents, ie the drivers. The tradeoffs will not drive everyone to the same solution. Some will, some won't.
I think this discussion may be missing the point, and the foreign comparisons while insightful don't offer a clear definitive answer. What is clear is that a faster train between Toronto and Ottawa, and Toronto and Montreal, does move us a quantum in terms of time and energy expended over today's trains. That quantum may or may not push the train ahead of other modes (personally I believe it will, maybe not for everybody, but for enough). It especially rivals or betters air travel for business travellers looking for a one-day round trip, which is a very common use of airplanes at present. A round trip in one day for business by train is a very long trip today, whereas air may mean rising early but likely getting home in time to watch the end of hockey or baseball before going to bed. And for non-business travellers, it changes the need to plan a day in the itinerary for the train trip versus getting good use out of the day and getting there as well.
And the walk-on, walk-off nature of the train, assuming very high schedule reliability, is far better than airport security, uncertainty over when flights actually leave, bouts of delays on tarmac before takeoff, and waiting for luggage at the other end.
So modal share is likely assured. Maybe not 80% as elsewhere, but close enough to make the value proposition generally favourable. At this point, in the absence of better data, we are just approximating. I would not overthink this at this point.
