Never done it before. Looking at the YVR guide, it seems we have to exit into the insecure area and then go back through C gate security.
Is this right? Seems at YYZ you can do it without exiting.
I've only done the connection through YVR from US on AC, not another airline. You go through Customs but do not leave and go through Security again. If you tell the people in the Customs Hall that you have a connection, they give you a card, and direct you to another area to see a Customs / Border agent. From there you board a bus that takes you to the C-gates (located across from the MLL).
There are some other threads here that cover this topic and you can reviews' experiences.
