Really? So even if my medical exam result expire when they process my application that will be fine as well? But I am not sure how to prove that to them though. I have receipts (physical check, lab, xray but no form showing my results etc.) and my last work permit application shows that I had passed the medical exam on October 2019. I emailed ircc but their answer was not at all helpful about the situationYour documents get locked after you submit your application to IRCC even if they are expiring soon. Make sure that they are valid until you receive your AOR.
