The fonds consists of one of the most complete collections of early municipal material to have been preserved in the Province of Ontario. It includes petitions, ledgers, reports, receipts, statements and correspondence. It also contains original motions and rough minutes, which are generally not kept, original by-laws (as well as some drafts and copies), summarized collectors rolls, assessment lists , and a school monies account book. The fonds provide a detailed account of activities of the newly established District Council of Brock, and its administrative and legislative powers. It also reflects very closely the primary concerns and needs of individual citizens. The social, economic and political issues confronting a municipal government during this period are also documented.
