i'm not sure if you can see that medicals were send on GCMS notes... but when they are reviewed and passed or additional tests are required - then you'll see it in GCMS notes...
if you received GCMS notes on August 7 then you must have ordered them around July 7... my expirience with GCMS notes is that they show the status of the case on the date when they were ordered (+ maybe couple of days) not the date when they were sent... so it means that there was no pass/additional tests decision on July 7...
Do you know when your medical results were delivered to Ottawa? because even if you completed the medicals on June 20 - it might take a doctor up to 2 weeks to send medicals + couple of days for postal service... it is possible that they were not reviewed yet by cic on July 7...
in my case medicals were delivered to medical office on March 8 and reviewed on March 15...
