Donalda Farm
This part of the Don Valley was first permanently settled in 1825 by the Gray family, who farmed and operated some of the original 'Don Mills', including a gristmill, sawmill and distillery. In 1916, mining magnate David A. Dunlap and his wife Jessie Donalda Dunlap purchased the site for a model farm and country retreat they named "Don Alda". The Dunlaps incorporated the original Gray residences and portions of the gristmill into their farm, and in 1920 built this residence with its dramatic Doric columns. In 1952, E.P. Taylor acquired the farm as part of the planned development of Don Mills. It was eventually redesigned as a private recreational club for families and officially opened as the Donalda Club in 1960. The Dunlap residence was expanded by architect James A. Murray to serve as the clubhouse. The Donalda cattle barn, and Gray's mill, laneway, and houses are listed on the City of Toronto Inventory of Heritage Properties.
