As it explains, it's a security review of applicants to screen out terrorists, spies, and other people that might be a threat to Canada. As far as I know, it is routine for immigration purposes. Although the search is done by a department outside of IRCC, it is IRCC that deciphers the information they receive from the Security Screening.
