    Directory of Personal Information Banks (PIB)

    The AESO is required to compile and publish a Directory of PIBs. PIBs outline the types of personal information held by a public body and will detail:

    • The location of the information bank;
    • The kind of personal information contained in each bank;
    • The categories of individuals each bank pertains to;
    • Why the information was collected and how it is used or disclosed; and
    • The legal authority for the collection of the information.

    A personal information bank does not provide direct access to an individual’s records.

    The AESO is committed to the delivery of exceptional service to our customers. In keeping with this commitment and our Code of Conduct, we are dedicated to maintaining high ethical and business standards and obeying all applicable laws, rules and regulations in every aspect of our work.

    The AESO Ethics Hotline is a means to anonymously report anything that is believed to be in violation of the AESO’s Code of Conduct, is considered to be unethical behaviour or is illegal.
