The Ontario Heritage Act provides a framework for the protection of cultural heritage resources. It defines the municipal and provincial roles in heritage conservation.
Municipal clerks are required to keep a register of properties of cultural heritage value that lists all properties designated by Council in the jurisdiction and Council can list also include other properties it believes to be of cultural heritage value on a muncipal register.
Municipal Heritage Committees advise councils on the exercise of its powers under the Ontario Heritage Act.
Cultural heritage resources found on property owned or managed by the Government of Ontario are protected under the Standards & Guidelines for Conservation of Provincial Heritage Properties.
