In most cases, yes, although that depends on the institution. For example, a large institution may have one office for access to information and another for privacy. That way of doing things may be practical for a department with 20,000 employees, but, on the whole, the office of each institution combines access to information and privacy. There are benefits to that. The two acts are similar and must often be weighed, for example, when an exemption is sought for personal information.
