Passive aggressive dismissiveness aside, the process is indeed a mess despite whatever physical constraints currently exist at YVR.

Hopefully the professionals will continue their efforts to improve the ITD process at all major airports in Canada. In the meantime, places like FT are a great resource for people to learn from others’ experiences and be better prepared for future travels.
