I got reply from aircanada, which suggested to contact lost+found by thier "web chat" system.  Thus, I told that it didn't work, that's the reason why I wrote by email.

Their web pages has been fixed to remove links to the "web chat" system.  That's the improvement.  But I don't know they accepted my request to forward my message to lost+found.
