VIA Rail

It would also be nice if a third VIA train could tighten up connection times for trains to Ottawa and/or Montreal.

VIA will need more reliable service before they can tighten up connection times.
I was on a train from Montreal that had a 50 minute connection to the Kitchener train. (which turned out to be the exact same train, actually)
We arrived in Toronto 30 minutes late. Meaning only 20 minutes for VIA to clean and restock the train. But not just that... we ended up holding for another 25 minutes while we waited for an Ottawa train to arrive (which was about 40 minute late) and for the passengers to board.

VIA has to leave an hour between connections, or else the schedules will be blown even further out of water.

I couldn't help but compare the experience of a 50 minute layover to Japan

In Japan, a 50 minute connection means:
1) First train arrives on time
2) Walk around transfer station for 40 minutes, have lunch, get some minor shopping done in the station.
3) Arrive 5 minute early to the platform for second train
4) Leave promptly on time

In Canada, a 50 minute connection means:
1) First train arrives 30 minute late
2) Be instructed not to leave the train/waiting area, as the next train is scheduled in 20 minutes
3) Second train arrives 30 minutes late
4) Leave 40 minutes late, 90 minutes after your scheduled arrival time, having accomplished nothing.
