Request for personal information about someone else
Requests for personal information not belonging to the requester must include signed, recent (less than one year old), written consent from the individual to whom the personal information belongs.
To facilitate processing requests for personal information, we also recommend that the
consent of all individuals who may have personal information included in the
records be obtained and provided with the request. For example, in the case of immigration records –
consent should be obtained from the spouse, sponsor, adult children or any other person appearing in the records. Consent may be provided by completing the Authority to Release Personal Information to a Designated Individual Form (IMM 5475) or by way of a written statement indicating the name of the person giving the consent and to whom consent is being given.
