Heyy
You know what, the medicals are sent in by the doctor who takes them, and you need to show the doc your passports to get medicals done,And you have to send in your passports yourself.
So I am sure you can wait and send in your passports, earlier they use to send passport request when they had decided on your case , so I dont see a problem in that. Just dont wait for 2 months to send in your passports send them 3-4 weeks after medicals have been sent, so its not delayed due to late submission of passports.
They start the Background checks after medicals are received, This I have read in some blog but cant confirm that.
Best Of luck with medicals, Also u can get medicals done only by a doc who is registered with the Canadian high commission, they have a list of doctors worldwide you can check on the website.
well 25 days to be exact, and time taken is case specific so just have to wait my turn, and it will take the time it will take.
