You have this totally backwards. CN's track is maintained well enough. Growth in business, and the drive to longer trains, is what turned the optimal configuration of the physical plant on its head. The track capacity is barely adequate to keep freight moving because of the dearth of passing sidings long enough to accommodate today's "land barge" trains, along with the huge increase in the amount of freight being moved.
If you look at their
capital program, it's apparent that they are in crash catchup mode. That program was a reaction to the system reaching near meltdown, along with rethinking and recovery from some of Harrison's more extreme constraints. Certainly, CN should have been adding track all along, instead of diverting capital to the shareholders. But that's now water under the bridge. The surplus capacity that made it possible to serve VIA from the seventies until the last decade has disappeared as freight business has grown.
CN is adding only enough capacity to stabilise its operations and prepare for further growth in business. To accommodate VIA, they would have to add further capacity. To return to operating the Canadian on a traditional timing and timeliness, someone would have to provide that capital or at least guarantee a return on it. The price tag for that would kill passenger service for good.
