It takes time between when medical gets sent to IRCC and when it is input in the system. This results in a time where it stills says you need to submit a medical but you have recently sent in the medical. Also if there is anything abnormal or anything that came up in the medical that is of concern, applications are sent to be reviewed by an IRCC healthcare staff so that can also lead to longer processing times. It will either result in a request for additional testing or information
