Q. I’ve read in one of the recent posts that a background check is a standard procedure and everyone has to go through it. The post also said that this “background check” starts as soon as the application is lodged. This all sounds great, because I thought this check is only started AFTER the interview and is done only if the immigration officer deems it necessary. This is at least what I understood from the Overseas Processing Manual (OP Manual). The OP manual says that after the interview, should an immigration officer think it necessary, he/she can contact any other Canadian processing offices to obtain further information about the applicant.
Which is correct?
