Don't know exactly where the boundary is, but after going through passport control at YVR the agent would sometime say "Welcome to America," as I was at that point on US soil. It's the flying through Canadian airspace before entering US airspace that has me confused
Unless preclearance gets revoked. Preclearance only clears you to land at that specific airport w/o going through customs apparently...not entry to the US officially... This happened in YYZ in 2015:
I was in the preclearance zone in the old terminal 2 commuter flight area, and a couple had just missed their flights. They were rescheduled to fly in 90 min. The Air Canada GA agent told them that they MUST leave the preclearance area because they were only cleared to land at CLE and not that the location they were rerouted to. From my understanding, they had to clear CBSA and then re-clear CBP Preclearance. Maybe rules have changed since then
