It excludes every privately owned office building, and the Directory records condition on a federal assessment scale rather than a market classification. It is not a rent, vacancy or availability source.
Privacy: Official_Contact_Name, Official_Contact_Telephone and Official_Contact_Email are present in the source and are never read. The custodian named here is a federal department or Crown corporation.
