Did you actually attempt to buy a ticket though? On the Canadian site, the front page advertises the 'cheapest' rate, which you can only get if you buy the first couple tickets on any given ride. After that, the prices escalate (they don't hide that from you though... it just not on their front page).

Same here - I remember when I was a student, everyone would use MegaBus rather than the trains as they were always much cheaper.

I've seen them remove unprofitable routes, but even then I can't figure it out, since running a fleet of buses must be a fairly costly operation.
