The series includes working files related to properties in the Maillardville area that were assessed for heritage value by external contractors in 1986. The files include photographs taken by the assessors, a copy of the typed assessment of each property, and related documents added by Planning and Development staff over the years. Related documents include copies of land titles maps, permit applications, copies of reports to Council, correspondence, copies of Bylaws, engineering reports, copies of assessment cards, copies of news clippings, and colour photographs.

The collection consists largely of research materials and notes created in the preparation of Boire's book "With Hearts and Minds" published in 2016. The remainder of the collection consists of materials collected by Boire from Caisse Populaire Maillardville Credit Union, as well as accumulated material pertaining to Boire’s involvement in several community initiatives, such as the Maillardville Residents' Association, Maillardville revitalization and planning, and Place Maillardville.

Materials include correspondence, photographs, administrative records, interviews, reports, handwritten notes, clippings, advertising and professional materials, newsletters, research materials, prints, postcards, ephemera, a map, embossing seals, a lid from a glass milk bottle, and other documents. The collection also includes a manuscript copy of “With Hearts and Minds”.

The file consists of assorted photographs from various donors featuring Canadian Western Lumber Company reps at BC Children's Hospital; Port Coquitlam scenes; Theroux Family portraits; Lady of Lourdes school photographs; a Maillardville police detachment; May Day parades; social gatherings in Maillardville; and Maillardville's first restaurant.
