At Shared Services Canada, we are responsible for managing technology. In terms of information management, the files and documents that must be kept under Treasury Board policy and the legislation under which we operate are not destroyed. They are retained due to the obligations of the various departments. In the case of the Old Age Security Program, for example, the documents are kept for dozens of years, I believe. Documents that must be retained are saved in the information management systems.
