I have posted my story before on my PR expiring while outside of the country, my initial plan was to enter via the US border coming into Vancouver from Seattle with a British passport, however it occurred to me there may be a better method that may prove more simple but, i need to know if it will work. If i book a flight from London U.K to Seattle that has a layover in Vancouver can i just leave the airport without the Canadian border knowing I am a PR with an expired card? So i would just leave going through the non-Canadian citizen route at the airport.
