Whats your timeline and when was the GCMS notes request made under the Privacy act? This is strange, as the notes are supposed to have many different sections that give information on the many different aspects that I mentioned in my earlier comment as separate sections. The last section of the document that I received had a "Notes" section, where I could see all the hand-typed notes of the officers who reviewed my application and made recommendations. I requested the notes under the Access to Information Act. I am not sure if there is a difference between the notes released under the Access to Information Act and the Privacy Act. Perhaps some other member can clarify.
The email that I received which contained my notes had this part:
"Please be advised that you are entitled to submit a complaint regarding the processing of your request to the Information Commissioner within sixty days of the receipt of this notice. The complaint form can be retrieved at:

Should you have any questions, please do not hesitate to contact us by email at
ATIP-AIPRP@cic.gc.ca"
I am quite sure that you would have received a similar email that contained your notes, and it too may have information on how to submit a complaint or where to ask for more information. I would recommend writing an email to the email address specified in that email, to ask if either your notes have been incompletely released or if you should submit another request under the Access to Information Act to receive more detailed information.
