Home Smith Park is situated on the west bank of the Humber River, opposite Etienne BrulŽ Park. It commemorates Home Smith's contribution to community development in the Humber Valley. Robert Home Smith was born in Stratford, Ontario on July 12, 1877, the son of a Manitoba Supreme Court judge. Although his interests lay in architecture, Home Smith's mother convinced him to study law. Unfortunately, a serious illness left him partially deaf, so he abandoned the legal profession to pursue activities less dependent on hearing. Home Smith had a strong interest in developing land and by 1906 had purchased over 1,200 hectares in the Humber Valley. He began development of the Old Mill or Kingsway subdivision in 1912. Houses were built individually by owners on planned, subdivided lots in communities surrounding the valley. The Kingsway and Old Mill neighbourhoods may have been the first planned, fully serviced subdivisions in Toronto. Besides developing land, Home Smith also built the Old Mill Tea Rooms, constructed an electric train service along Annette Street, and designated land for commercial and recreational uses.

In 1994, the Boy Scouts of Canada planted over 4000 cedar and sugar maple tree seedlings in Home Smith Park.
