Timatic says "yes".
Also, I don't think UA flies SEA-YVR, so that would be an AC flight, which wouldn't be allowed on one ticket due to cabotage rules- you can't use a non-US carrier to transport between two US cities on one ticket. Otherwise, FTers would fly XXX-YVR-JFK on CX on one ticket all the time...
