High-Speed Rail (HSR) - Toronto/Pearson/Kitchener/London

[tomh009]

I counted 34 direct flights from YYZ and YTZ to YUL, probably 150 seats on average, so that's roughly 5000 seats of capacity per day.

I think that’s more but not nearly 10x (more like 1.5x-2x) what via rail can carry. 

That said I think 150 is a low estimate unless many of those flights are embrarer or dash8 planes. Even small 737s seat more and the larger variants can seat around 200.

Embraers and Q400s, lots of A220-300s, a few A319s, some 737-8s, and I saw one A321 and one A330. I would guess an average seat count of somewhere close to 150.
