No, you cannot give medical after AOR. You need to wait to receive instructions from IRCC (IMM 1017E form). Besides, in most cases applicant will get extension on medical result by the decision of the processing officer. So, you may never have to do it.I also got update from my MP and it says medical expired, criminality and security not started. Do I have to redo all the medical before waiting for them to ask me? or wait for them to request?
