There are relatively few third-party affiliate stations of Canada's commercial networks; they typically follow the schedule of an O&O in a nearby major market, but with opt-outs for local newscasts and other local programming, and may also simulcast that station's newscasts in timeslots where they do not air their own (essentially acting as a third-party semi-satellite).
