You will receive an emedical form that you can upload with a webform.
Some will say you don't need to do anything, some say upload the document with a webform.
I did the medicals almost 2 weeks ago and uploaded the emedical the same day.
Verified with IRCC today and they said they received the emedical and waiting for the team to attach it to my application.
How did you verified with IRCC?
