Thank you!
I know, don't worry!

Unfortunately, the article is pretty representative of almost every single article I read in the LFP regarding passenger rail in it's overly negative and neither well-researched not well-reasoned opinion of Canada's national railway operator...
As the segment between White River, Thunder Bay and Winnipeg does not fall under the other two of VIA Rail's three mandates (
regional service to communities without year-round road access or
intercity service on a near-commercial basis), the only way to get the federal government to restore VIA service along Lake Superior is to reroute the Canadian (which is part of the
transcontinental service mandated by the Confederation agreement of 1867).
However, and as you correctly noted, rerouting the Canadian onto the CP line east of Winnipeg would require to restore a
regional service as it was provided between 1981 and January 1990 (when the
Super-Continental was merged with the
Canadian and jointly operated over the CP line east of Winnipeg).
As I've noted back in January (see quote below) by simply extrapolating the per train-km operating costs of the Winnipeg-Churchill service, operating a thrice-weekly loco-and-coach-and-sleeper train over a distance of 1,499 km rather than a RDC service of the same frequency over a distance of 484 km would increase operating costs by the order of magnitude of almost $10 million and with neither creating any significant currently untapped ridership potential nor anything else of significance which would advance any of the three aforementioned VIA mandates:
I'm not arguing against restoring passenger service along the Lake Superior (and I would be the first to travel on it!), but I don't see how it could be convincingly justified as being the responsibility of the federal over the provincial taxpayer...
