@legalfalcon Thanks for your reply . I did call IRCC yesterday. The agent said he can see my valid medicals in the system expiring in July 2022. He said you don't need to do it. He said the system might have generated my remedical request automatically along with my family. But I am wondering how about the remedical form then, where they generated new IME number for me.If your meds are still valid you can inform IRCC of the same by webform.
As regards the address, did you change your address and if you did, did you make sure that you only do it for your self and not the dependents since they are not in Canada.
Also, last year I was india for 5 months. Can it be the reason by any chance for the remed request? TIA
