I guess you submitted your application online and that is why your status is showing SUBMITTED. Others did paper based and send their completed paper application through courier to IRCC, the date the application get to IRCC through courier is AR (Application Recieved), and your own AR is same date as Application Sunmitted date. Everyone (either paper based through courier or online submission) will now wait for AOR (Acknowledgement of Receipt) email from IRCC, before other processes continues. The date between AR/Submitted and AOR is not easy to predict, it depends on how lucky you are, and ranges between 5 months to 1yr if not more. Do you get it now?
