As for customs, hopefully some US guys will be able to answer that one for you!
Which isn't the case as he is connecting from US through YYZ to HK... so he has to clear Canadian customs...not US customs. I think its a pretty easy procedure. However I don't think YYZ T3 has a through check through procedure. Which means that you need to pick up your luggage and then recheck through to HK.
