We’re in the same boat. My initial thought was that everything was done on the doctor’s end, but she also advised my husband to upload the same form you’re talking about. Tried to do it through my account and experienced the same difficulty. I checked ircc website and it says if you’re doing a medical exam after you’ve sent your PR application you don’t need to submit anything. It’s been a week now and we haven’t received any type of notice that they have his medical results, but his file’s been transferred to the visa office in Kingston, JA. I think my husband’s gonna reach out just to double check that everything’s good. I have a feeling the doctor was mistaken but whatever I find out I’ll definitely share with the group.
