Fonds consists of records created and received by the Toronto architectural firm of Mathers & Haldenby, documenting projects with which the firm was involved.

Major architectural projects documented in these records include Queen's Park Phase II, Upper Canada College and various hospital buildings in Toronto; various buildings at the University of Toronto; alterations to the Parliament Building and the Supreme Court Building in Ottawa; the National Library and Archival building in Ottawa; various buildings for Queen's University and the Royal Military College in Kingston; and buildings for Dalhousie University in Halifax.

Other architectural projects documented in the fonds include residences, commercial and industrial buildings, cultural and academic institutions, hospital buildings, and office buildings, mostly located in Toronto but also throughout Ontario, Nova Scotia, Quebec, Western Canada, Australia and the Caribbean.

Records in the fonds consist primarily of architectural drawings by Mathers & Haldenby or firms with which they collaborated, as well as mechanical drawings by contracted firms, and reference drawings from architects who had previously worked on some of the buildings. In addition to original drawings and prints, fonds includes reproductions of drawings on aperture cards and in microfilm format.
