Thanks for the reply. We are in very much same situation. Even I got a remedical request about a month ago. When my IME`s were not seen on emedical system, even my doctor suggested to go for upfront medicals. But I thought of clearing this issue with visa officer, so I wrote a mail to him for clarification because as per cic`s handbook on medicals, its clearly written that for upfront medicals, one should not have any existing earlier medical file and also it is not for IME non EDE type`s. I believe almost all PR applicants medical forms are non EDE types. So, its my opinion that upfront medicals are not for us. Lets see what visa officer writes back.
Please update me in case you get any information in this matter. Thanks once again.
