I don‘t believe that the Conservatives (or even: PP) are hostile towards VIA in particular, they just dislike public competition against private corporations and have a distorted view on VIA, which is not helped by VIA publishing its fully-allocated cost figures much more prominently than its direct ones.
Once the Conservatives realize that VIA is actually profitable where it competes against the private sector (i.e., in the Corridor, where it competes against bus operators and airlines, and the Canadian during the summer and particularly in the Rockies, when and where the RMR operates) and complementary where it isn‘t profitable (e.g., on the Winnipeg-Churchill route, where many tourists fly first to Winnipeg and then to Thompson to only ride the train for the second half of its journey to the Hudson Bay, before flying back all the way from Churchill), they might actually happily continue funding it and tuen it into a policy tool, like Ford did with the ONTC…
Therefore, splitting VIA post-HxR might actually raise the value of VIA in conservative eyes, as it removes the parts they want to see in private eyes and allows VIA to focus on the markets which actually serve its Western or rural key constituents, which are increasingly neglected by private transportation offerings…
