Actually, I helped a client save about $800 on a 1-way fare 7 years ago by using that train between YOW and YUL. He had to get to YUL. Charter fares YVR-YUL were sold out and the AC Y fare was over $900. There were sell-offs available YVR-YOW for $129 at the time and that it what he gladly took. For that differential, 121 miles on a train was no hardship.

Epilogue: My office manager was very pissed at me because of the lost commission - the end of that month, I was fired, but from that office, I considered it a badge of honour.
