Input: I am a US Permanent Resident(Green Card). I booked a ticket from China to USA. The flight is operated by Air Canada. It will have connecting flight wait time 11 hours 20 minutes in Vancouver.
My question is that since the connecting flight wait time is so long, can I take a tour in Vancouver, I don't want to sit inside the airport, Is that possible?

Output:
Connecting flight wait time 11 hours 20 minutes - is it possible to exit to see Vancouver?
