Greetings - I'll be arriving at T3 on Air Canada, making international connection to China Southern departing from T2 to Phnom Penh. We have 1 hour and 55 minutes to make the connection.

i) is it feasible?
ii) do we need to go out through immigration (and therefore need transit visa?), and
iii) can bags be checked all the way through to Phnom Penh from Vancouver, or we will need to claim and re-check them in Beijing (raising again question of time)

Thanks,
