I guess the objective is to wait until they collapse.. then claim there's no way they can be restored and the only thing left to do is clear away the debris. Hands are tied, I guess.
It doesn't work that way. There are certain obligations that individual government departments (including DND) have with regards to government buildings that have been designated as heritage properties. Just because a structure is old does not mean that it will be designated a heritage building. By the same token, Government of Canada buildings (with some exception for National Historic Sites and the like) are not usually maintained for the "sole" reason that it is a heritage building; it is supposed to be used. The following are the heritage buildings at CFB Borden.

Federal Heritage Buildings Review Office
The primary objective of the Federal Heritage Buildings Review Office (FHBRO) is to assist federal government departments in the protection of their heritage buildings, in accordance with the Treasury Board Policy on Management of Real Property. The policy applies to all federal government departments which administer real property but not to Crown Corporations. This means, for example, that many post offices and all railway stations are not covered by the policy.
FHBRO evaluates all federal buildings 40 years of age or older in order to determine heritage character. It makes recommendations to the Minister of the Environment, who is responsible for approving the heritage designations of all Government of Canada buildings. Through this process, buildings are designated as either Classified, the higher level of designation, or Recognized, the second level.
FHBRO also provides advice to federal government departments that wish to make changes, or interventions, to a designated building, to ensure heritage character is protected.
The Government of Canada owns more than 40 000 buildings, of which, more than 20 000 have been evaluated and over 1300, or 3%, have been designated. These buildings are recorded in the Register of the Government of Canada Heritage Buildings, which is maintained by FHBRO.
