Did you try ordering gcms notes? I'm in the same boat, the application is stuck in security.November 2021 applicant here. Done with medical 2 times and submitted pcc 2 times. When IRCC asked medical exam for the 2nd time they didn’t asked medical for my son. Still silence from IRCC Vancouver office. It’s been more than 3 years now and it’s so frustrating. Anyone else in same boat? Applicants from pakistan.
