It's where the applications come, after referrals have been made from CIC. Then it's CBSA that's responsible for compiling information, which will include open-source and classified information, and information from RCMP and CSIS, and possibly other security partners relevant to the particular circumstances of the application.
C'est elle qui reçoit les demandes adressées par CIC; elle compile l'information, classifiée ou non, provenant de la GRC et du SCRS, et éventuellement d'autres partenaires concernés par la demande.
