First of all, that corporate plan is from 2017, prior to receiving approval to order the new fleet. There are
3 newer corporate plans available (and the 2021 one will hopefully be published soon).
As for the long distance fleet, it certainly is an issue (it becomes more apparent how bad it is in the
2020-2024 Corporate Plan). Unfortunately, as the long distance fleet replacement will be more expensive than the corridor fleet replacement, as VIA owns over 250 long distance cars (compared to the 160 corridor cars replaced). I don't know if any government will want to invest that much money in the long distance services. Then again, they won't want the responsibility of cancelling the services either, so they will most likely die a slow and painful death.
