Found AC 103 24 Jun YYZ-YVR in E for CAD$285.00 all in per pax and then a separate one way DL ANC-CVG-YYZ on DL 762 & 5137 and that portion is CAD$333.00, or a total all in of just over CAD$600 per pax. Note that the DL ANC-CVG is an overnight flight.
Best I could see at a glance. Good luck with the decision, but don't leave it too long.
