Is there really a CBSA blacklist?
Is there really a CBSA blacklist if they capture and reject something that is shipped to you? A friend in Hong Kong is sending me a box of old things and I forgot to tell him not to include some old restricted parts that he might have thrown in there.
I know that there is a blacklist for international customs through airports in which you will be flagged and they will always check your luggage - but is there such a thing for things potentially arriving by mail? I know many people have recieved the letters that said that customs were not releasing restricted items, etc. but is there something like a blacklist I should be worried about if something is sent to me?
