Dear All who have been waiting long for medicals or after passport submission please note that background checks can take many months to complete. If you haven't heard anything for long don't assume something is wrong with your application. It is their usual procedure and some countries are listed as high risk countries where even a more vigorous check takes place. Please check the following link I found useful. Thanks.

Security Clearance/ Background Checks
Background checks are carried out on every Permanent Resident applicant over the age of 18. These checks are used to identify criminals and known security threats (espionage, subversion or terrorism). To ensure that the protection and safety of Canada is maintained, various sources are consulted for the completion of background checks, including but not limited to visa application forms, intelligence information, criminal conviction records and immigration records.
Once all information is received, it is carefully reviewed to determine the likeliness that the applicant is a threat to Canadian security. If any questions or concerns arise a Security Interview will be scheduled in order that the Immigration Officer may discuss these findings with the applicant. Failure to pass the background check is grounds for an immediate refusal of the Permanent Resident Application.
Citizenship and Immigration Canada (CIC) in conjunction with the Canadian Security Intelligence Service (CSIS) administers the background checks. Since Canadian officials confer with other governments, departments and/or organization it may take several months for the completion of the background checks.
A PERMANENT RESIDENT VISA CANNOT BE ISSUED UNTIL SUCH TIME AS THE BACKGROUND CHECKS ARE CLEARED.
