Sumner-Bronfman House

After Samuel purchased the Sumner mansion, his brother, Allan Bronfman (1896-1980), acquired the house to the east and then they both purchased the property between them (the former home of merchant James Coristine) which they demolished to create a garden. In 1929, Samuel Bronfman consulted the original architect before employing the architects Hutchison & Wood to make several improvements to the Sumner place: a stone wall was rebuilt around the parameter and terraces with formal gardens were laid out. Sam's instructions to the architects had been simple: "buy the best". Over the years between 1938 and 1973, Sam and his wife carried out at least six further significant extensions.

The house still stands on grounds of 1.5-acres. Internally, the large windows in both the drawing and dining rooms offer views over the St. Lawrence River. The original wood panelling from Sumner's era survive in the dining room and study. Sam Bronfman died here in 1971 and his widow, Saidye, continued to live here until she too died in 1995. It remains a private home still owned by the family: it was bought in 2001 by the current owner, their grandson Stephan Bronfman, who has made his own improvements.
