I have ordered GCMS notes before getting the AIP for my client. But the funny thing is I got email from IRCC with AIP confirmation (actually webform reply where they mentioned his visa is approved in principal) on email and GCMS notes both arrived on the same day. So it didn't mean anything much for me or my client.
However, that GCMS shows the visa was approved in principal in June 2020 (can't remember the exact date now).
The application submitted on February 2020 (complete app with biometric & passports and everything).
On the other hand last week I applied another GCMS notes for myself. Although GC key indicates I passed medical on 22 July 2020 (submitted 20 June - 2nd attempt for study permit, 1st refused on June 2020 :/ ). Since medical update there's no changes. Still showing "We will let you know when we start reviewing you eligiblity."
Present situation with application is I'm waiting for my GCMS notes. Applied on 20 August 2020. Let's see.
