It seems your clinic has either not submitted your medical to IRCC or made a mistake in filling your details (wrong name, date of birth, passport number, etc.). Go for a medical exam ASAP! Try with an other clinic this time (Most experienced or most reputable). Also, if they give you some kind of an IMM or IME document or receipts, submit it via webform as soon as you have access to a computer. That way, even if there’s delay and your application ends-up being cancelled or rejected, you’ll be able to request a reopening based on your webform. Don’t worry, it’s a worst case scenario and much more unlikely to happen in your case, but has happened in the past. I myself am a victim of late webform processing, ending up with eligibility being tagged with Review Required and having to still wait for a decision even after more than a year since AOR. Just do the exam, don’t give them a reason to linger on. IRCC is very brutal when it comes to missing the first chance being finalized, because your case exits the normal processing chain and they just put your file in a queue that doesn’t have an end date so nobody bothers to look at it for years.
