Hertz here in canada is the same YYJ,YEG,YYC,YWG,YYZ,YUL,YHZ,YYT,YQM, never fill in anything on the form, some ask upon exit if you noticed anything, other then major damage, it is never listed. They tried to nab my boss one time for a scratch on his car, he simply told the manager where to go (all your vehicles are scratched, you write nothing on the forms, and are just trying to steal from clients) very much out loud in front of a growing crowd. The manager put his tail between his legs and wished us a nice day...
