This is what I found from other thread. Just shared with you guys so we have have better idea about 'Security' thing. I hope this is helpful to you and receive PPR asap.
The last and the final stage is the security. This is a serious & time-consuming stage, involving many agencies, including Canadian Security Intelligence Service (CSIS), International Police (INTERPOL), Criminal Database Checking & touch-base with Local Police. Many things are considered here. Number of countries visited, Applicant coming from 'certain' countries, past law enforcement or military record, Prolonged stay in a country w/out sufficient docs to prove cause, frequent traveling to certain nations, your *Name (?), Inter-Religion/Nationality Marriages etc. If everything is simple & straight, the file soon gets into the 'final review' stage. If there are any 'red flags', the case goes into a 'spin'. Then the file might go to the local Police/intelligence agencies; the outcome/timeframe of which is beyond the control of CIC. And thereby the timeframe can be anything [sometimes beyond 1yr]. But, usually this stage should be over within 1-2 months. However, a point to be noted is that the applicant can also be called for an Interview [at this stage], due to this reason. For some people the security has a quick turn around.
At the final review, when the security results come in, the PPR is issued.
