That's just dumb. Most anyone whose taken a Corridor route will be happy not to have driven, bused or flown to their destination. It's a great way to travel.
As for Sudbury, we have up to two trains a week on Tuesdays and Fridays at about $75 a trip to Toronto. And we have up to two trains a week on Sundays and Wednesdays at about the same cost back to Sudbury. How many passengers use this service to or from Sudbury? If for example, one was going to postsecondary school there (mainly one of Laurentian University, Cambrian College, Collège Boréal, and the Northern Ontario School of Medicine) how many students take this train to visit Toronto or return to school? The VIA to universities in Ottawa, Kingston, Montreal, Windsor and London can be jammed with students makes this same trip, for example. And business people going to Sudbury, arriving on the Sunday or Wednesday and staying for a few days before returning on Tuesday or Friday, is this popular? I would argue that the Sudbury to/from Toronto train is not popular is that it takes too long, not that it is infrequent. And there's no way to make it faster while VIA relies on freight owned railways, an issue that cannot be addressed due to the lack of passenger traffic.

If I studied or had business in Sudbury, I'd take the train. It looks like fun.
