Couldn't agree more - especially compared to the dungeon in Montreal and the never-ending construction in Toronto.
Living as I do, right on the corridor, this has actually been the most fascinating development to watch. Montreal-Toronto used to be the priority route, with Ottawa-Toronto an afterthought. The former's number of trains is basically stagnant, but Ottawa-Toronto increases have been nothing short of amazing. It has really turned into one of those examples where it's not worth flying, as discussed elsewhere. Passenger turnover is also greatest on stations west of Brockville, ON, which can be served by both routes. There are obviously other factors in play, and the scenery between Brockville and Ottawa is quite nice, but the increased service has definitely been a positive.
