Could there be district municipality or regional district
engineering/road department shapefiles or cad files floating around for
some of these areas?

Interestingly, Stats Can and NRN disagree with each other on some of the same points that I noticed in vreimer's differences against NRN, but Stats Can introduces yet another variation of errors in the Valemount area. In other words, vreimer, Google, Bing, NRN, and Stats Can all have slightly different versions of Valemount. Not one of those is exactly like any of the others.
