Individuals can determine whether their personal information was used by the federal government for data matching by referring to descriptions of the Personal Information Banks (PIBs) available through Info Source. Info Source is a series of publications and an online resource designed to assist individuals in understanding how the government manages personal information. It is managed by the Treasury Board of Canada Secretariat and provides information about the existence, purpose, and use of personal information banks within government institutions. This resource is the most direct and reliable way for individuals to identify how their personal data is handled and if it has been used for data matching purposes.
