I'm not sure how much demand there is for a western service from YYB. When I was there, North Bay's economy was largely geared around the military base, its role as a regional hub for provincial government offices, and Canadore College and Nipissing University. The most significant private sector employer I can think of was the Boart Longyear drill bit plant. So, with the possible exception of the base, there wasn't really much there to connect YYB to the western provinces.
However, I can see a YYB-YHM service being popular with college and university students, and for family traffic, since it seemed that many long-time North Bay residents had family members who'd moved away to find careers.
