I don't think the delay is related to circumstances as such, my case should also be straightforward. We are just unlucky. Out of frustration, I raised an atip with CSIS as well and they replied that they had responded to IRCC query way back in Feb.Looks like we are in same situation , it says fingerprints required as per GCMS, but no request yet. It almost 3 months now in the same state . Though I got test invite from Niagara , it is at Sydney right now as per notes.
it’s so frustrating with the process , I had my reliability cleared last year ( ie they have all details already ) and haven’t been out of Canada much and no history which may cause for delay .
