CIC absolutely never does this way therefore no one thinks this way. Simply. When Recipients (SCI, security guards,..) received your applications. It will be sorted in order to received dates. CIC officers just pick from oldest to newest arrivals ( sorted by first recipients) , check received dates and open your packages. For example Mr.John picked application A received on May 10 ( the oldest one when he came to sorted files at stored files area) he opened and check but for some reasons like complicated applications, more information needs to verify, John is new recruited employee or a week after he opened it he took 2 weeks vacation,...( I believe who opened it will be responsible for it until decision made unless some special exceptions) while Ms Lona picked an oldest received application on May 26,2019. The application was very basic with appropriate information, Ms Lona will decide it faster than Mr.John. So it makes sense if an application arrived late but got news earlier. The important is your application arrived on or by June 28,2019 and confirmed by couriers
