I don't think there is a magic number of years to take as a specific reference.
Our recommendation would be that once it is determined that this person cannot be removed—cannot be sent back home—for various reasons, then we cannot just say that we have another couple of years to keep this person in detention or that we should not detain her any longer. At that stage, once it is determined that we cannot send that person back, you have to handle her differently. You have to put her back into the regular system of the Criminal Code.
