I don't think either that CIC destroys (or should destroy) any piece of information sent to them. Technically, sending additional or missing documents makes even their life easier rather than they asking you for additional info and then keeping your application in a pile of pending case until they actually receive the documents from you because I'm sure their target too must be to not have many pending cases. Don't worry, hopefully, you should be fine.
godhelp said:exactly cairo u r correct, i mentioned the temporary
addresses where i stayed during my consultancy
days. in the amendment i mentioned of my
permanent home address (where my
bank account, business, health card etc..) are registered.
hope they attach amendment to my file. someone in past
told me they trash any new additional documents they
receive from candidate, if they have not requested it.
