Fonds consists primarily of records related to the administration of the Scottish Centre of Montreal, including management of its building and finances. Other administrative documents include directories and guests. Fonds also includes meeting minutes and artifacts related to the centre's administration and social activities.

The lodge's records consist of a registration book giving the member's name, address, occupation, age, birthplace, wife's name, children between ages of 5 and 15, name of beneficiary, and occasionally remarks on the death of the member of cancellation of membership. Registration books survive from Primrose Lodge No. 49, 1887-1945, Denbigh Lodge No. 96, 1889-1944, Brittanic Lodge No. 113, 1890-1937 and Monarch Lodge No. 182, 1893-1948. Stray items of correspondence from banks or businesses may be found between the leaves of some volumes. The archive also contains two charters from Primrose Lodge, 1887.
