A friend asked me and I didn't know, so I'll bow to you. When flying from the USA to Vancouver, British Columbia (YVR), on the return flight back to the States (let's say YVR-ORD), do you clear customs in YVR or when arriving at ORD? I remember years ago flying DTW-YYZ and clearing customs in YYZ - both when arriving and when returning to the States. Blaine Thompson FWA
