Initially, I too thought that those who got document request were already in the safe as far as selection factor is concerned. But this did not seem to be the case since andy.fan got rejected after he submitted bank statement, due to insufficient number of points (he was refused the 5 adaptability points).
In my case though, I ordered CAIPS notes just before I got my document request, but when I received it a week ago, it was dated several days after the request, so there were a lots of movements in my file. It looks like the officer made the request for bank statement and PCC for me after he awarded me more than 67 points (I got 68 points), but I did not get any adaptability.
This is why I encourage all who already got document request to order their GCMS notes, just to see whether or not the visa officer has evaluated their files against the selection factor. I'm really curious.
One thing that is likely the case though, the officer is issuing document request during eligibility review, but whether or not it's before or after selection factor has been passed is still yet a mystery. I'll share the wording on my GCMS notes in a bit.
EDIT: the wording goes as follows
So you see, the request was actually made after he assessed my file against the 67 point criteria, so I will still stand by my earlier statement that, if an Ottawa officer made a document request at all, then most likely he would have awarded you more than 67 points, though the final result may still change, but at least I think he has accepted at least one year of continuous work experience from your application.
