I don't think there is any logic behind the IRCC delays. I am pretty sure they will blame it on Covid no matter what and process things as slow as they can! I feel like ordering GCMS is also a waste of time and energy as nothing matters and nothing changes. Despite asking several times, they said there is no problem with my file, it is the normal processing delay for covid, decision has been made for the last 7 months, the test was cleared 1 year 6 months before, 23 months+ and counting since they received the application! I doubt if they would process it this year! The online system (generic one) just got updated on July 13th, and it shows now the timeline of May 19-25, 2019! August 2019 seems like a distant dream!
