Applicants who applied pre December 2016 were part of the longer processing times, and IRCC made it clear anyone who applied beyond that date would fall into the new 12 month targets. It wasn't intended to speed up pre December 2016 applications. How is that unfair? This is one of the major optimizations to the process they made.
In any case, IRCC has a target of 80% of applications being processed in 12 months. You have not even hit that mark, so you are jumping to conclusions believing that you will. If processing goes past 12 months, they never promised that 100% of applications would be processed within that timeframe.
The way CIC treated pre-Dec 2016 is exactly unfair. Those applications were literally put aside so that they could guarantee a 12 months processing time for anyone who applied after Dec 2016. Those applicants waited 2+ years to receive a decision on their applications. How is that not unfair?
There was no jumping to conclusions here, the data is clear, the vast majority of August 2018 applicants did not see any background check updates until May of this year while applicants who applied post August 2018 had there background check start processing soon after their medical request. We are talking about a large group of applicants from a particular month who are delayed. Clearly not a one off situation. I don't think that anyone here can provide an answer as to why our applications are delayed. I believe similar to pre-Dec 2016 applicants, there was a policy change that took place that impacted our processing time.
