Hi Friends,
This would be abnormal in a normal case but it seems to be very normal in this special period of time. FYI, One of the friends of mine also sent his application to IRCC in March and has no file No so far.
Let keep patient because IRCC has just restarted processing the SUV Application at around the end of June 2020 and they may focus on processing the application received since Mar 2020 or before then your turn will come later.
Furthermore, the processing time of almost type of PR or Visa application has been delayed extremely due to the serious impact of COVID 19.
Cheers,
Kai
