Not to mention municipalities in the East (Port Hope, Belleville, Kingston) that would benefit from a high speed limited stop service to the airport.For VIA to pull out, GO would need to provide service to Stratford and St. Mary’s. The former being more important. I doubt that these towns would be left high and dry. Also don’t forget maintaining London-Kitchener service. Long term, I think that this corridor (London, Kitchener, Toronto) will be run by GO, with VIA focusing on the southern routes.
