Ryan Premises National Historic Site's management plan is a strategic guide for future management of the site. It is required by legislation, guided by public consultation, approved by the Minister responsible for Parks Canada, and tabled in Parliament. It is the primary public accountability document for each national historic site.

As a strategic and long-term guide, a management plan establishes a vision looking 10 or more years into the future. Its primary goal is to ensure that there is a clearly defined direction for the maintenance or restoration of cultural integrity and, in the light of this primary goal, for guiding appropriate use. Direction is also described for the heritage presentation programs, which are recognized as a fundamental means for achieving both protection and use objectives.
