You are all good to go.
The above process is just for those who didn't get any PDF COPR document in email. Like me. I just got an update in my CIC account that my application has been approved. no other email. I dont have copr email.
In covid situation we cannot say anything about medical extension. Its upto the officer to extend medical. sometime they ask to redo it. Usually they go with extension. You will be contacted if new medical needed.
