Sterile flight YVR-YYZ will generally only make sense if you are feeding off a number of flights. If you can arrange for NRT/KIX/HKG/BJS/SHA/TPE all to arrive around the same time, you can move the CNX pax to a sterile aircraft and move on.
However, if your loads aren't predictable, you run into an allocation problem. Too many pax, and you've got nowhere to put them, to few, and you're wasting an aircraft.
Meanwhile, unlike the other YVR-YYZ ops., you can't mix in domestic pax to pick up the slack.
