Immediately after AIP, it goes into processing background check whether you have submitted requested documents or not because they must have asked RCMP for our biometrics if done already, I got a correspondence Immediately after 1 month that they received my documents and they asked for passport bio data to grant passport exemption, when I listened to application status, it says one of our medicals is missing but I'm not bothered because I know they just haven't updated my file with the medicals yet. Don't worry, it might take time but we will all surely get there
