VIA Rail

That or book the VIA segments in two different transactions.

Yeah. I wouldn't book Kitchener-Montreal as one ticket. In general, booking as separate tickets means that they don't have a responsibility to accommodate you if there is a delay (also true for airlines). However, I've been stuck in a VIA-connecting-to-VIA delay on separate tickets and they have rebooked me on a later train at no cost. I would also book VIA Kitchener-Toronto at least if you are concerned about missing the connection, possibly on two tickets. Missing the GO connection Toronto-Kitchener is not as big a deal.

I am planning to book an Amqui-Toronto ticket (and connect to Kitchener) for April. I think I will book that as one ticket because missing the connection would be a big pain, especially if I bring a bicycle, which requires a specific Montreal-Toronto train. But it's still more expensive to do it as one ticket vs two tickets.
