The fonds reflects the Company’s involvement in the construction of buildings utilizing cement across Canada and comprises original photographs and some negatives of buildings. The photographs document construction over a wide range of time, geography and type of structure. The fonds reflects technical evolution of the use of cement construction, as well as the architectural evolution in Montreal and many of its public buildings. The major part of the photographs are of buildings completed by Canada Cement, and only a small number of the prints show the early factories and the equipment. Although the collection documents the company’s projects across Canada, about one third of the collection relates to Quebec and Montreal. Included in the fonds is one 16mm film "Concrete's Finest 50 Years".

This collection consists of 2 main subjects, arranged in 3 series: the first subject, structural projects involving Canada Cement and Canada Cement Lafarge, is divided into a Type of Building Series (subdivided by region) and a Regional Series (subdivided by type of building). The second subject, Canada Cement's own factories and its Montreal head office, is contained in a smaller Plant Series.
