After struggling for entire 1 year in these security checks, banging at the doors of my local member parliaments and looking at different forums, CSIS and CBSA related documents, I can confirm that the timeline that I have provided for extensive security checks is some where 9-12 months.
For the people who got their PRs in 6th or 7th months they are PNP inlanders. CEC people get their PPRs somewhere between 20-100 days. For FSW applicants it varies from region to region. For US citizens, people get their PPRs between 40-120 days. For Pakistanis the timeline is between 90-120 days. All these timelines are for those applications where applicants do not go through extensive security checks. Normal security takes 24 hrs to be completed. Some unlucky ones, like me, get selected for CBSA and CSIS security which is a 3rd party organization and their timelines are not restricted to the average 6 months as advertised by CIC.
If you are stats guy, then go to the immigration trackers, to confirm the above timelines.
