Via Rail already serves several towns in the 5000 population ballpark in the Corridor. Casselman, Glencoe and Gananoque to name a few. Having barebones stations in towns of that size is hardly unusual. I don't know how many people use them but it's obviously more than 1-2 per train, and it's enough to make it worth having some basic service. That doesn't turn the overall service into crap at all; most trains just go through without even slowing down.
