The background / security check is one of the three admissibility checks, and is done by CSIS. (The other two are medical, and criminality.) It's not public knowledge exactly what CSIS does, but you can at least verify they have your file:

sometimes cic send a letter to applicant or his lawyer that application is in background check and sometimes they dont each visa office is different
in my case my lawyer send an email to damascus to update status and they reply within a week that application is still in process undergoing back ground check. it may take between a month to 3 months each office/ application is different
good luck
 
Background checks are conducted in all countries where an applicant has lived. However, we will not contact organizations or individuals if it may place you or your family in danger.


Verification of information and documents provided (for example, there may be lengthy procedures for background checks in the countries where the sponsored person and his or her family members have lived or need for a second interview for additional background screening)
