I have seen Irccc saying processing applications from Oct 1st but people who applied on Oct 10th were already receiving extension. I would say apply for GCMS to find out the reasom for transfer.Well, when i check my application status and there is written that your application is in progress we will send you a message when we start to review your application and one of my friend also applied for extension on 1 October and he get a notification that we are reviewing of your eligibility. But I didn’t get any kind of message like that and one thing more when my application transferred to Edmonton office then i called to Ircc and they told me that we are processing 6th of oct applications and I applied on 20th oct so they didn’t reach there.
I had called irccc agent and agent told me my file was transferred for additional verification. But when then i received gcms which has reason mentioned as workload redistribution.
