NO, where there is light, there is no ghost...so no enlightenment.
However if you are looking to get educated instead....
After your background check is marked in progress (iP2), if you login to your CIC account and see that the status on your eAPR application shows "updated" but when you see inside, nothing changes. We call it a Ghost update.
Apparently, when the immigration officer gives final approval to your case file the application gets updated at their end but nothing changes on ours. But the system intimates the applicant.
Makes me think, if it is a bug, they forgot to fix.
