Moderator note: the thread has been re-opened following clean-up of a bunch of off-topic posts, which generated quite a few member complaints. The question regarding exiting the international area, as it applies to AC lounge access, has been answered by YYCCL3. Further discussion of CBSA procedures and airport layouts is very much off topic, as is discussion of the Verified Traveller program, which is covered in an excellent thread in the Canada forum.
