Description

Now part of the Art Gallery of Ontario in the heart of Toronto, this house was once the centrepiece of a fine estate in the suburbs of the town of York. Sited at the end of a long park, the house, with its original pedimented five-bay facade and brick construction, reflects the conservative British classicism that typified other estates of its time in eastern Canada. The designation refers to the original house on its lot as of 1970.

Heritage value

The Grange was designated a national historic site of Canada in 1970 because:

  • it is one of the few surviving residential estates belonging to prominent citizens from the town of York; and
  • the Grange, built about 1817, reflects the conservative influence of the British classical tradition of the 18th century.

The Grange was built about 1817 for D'Arcy Boulton Jr. in an area of the town of York populated by residential estates belonging to prominent citizens. Its symmetrical five-bay facade and central pediment reflect the conservative influence of the British classical tradition of the 18th century. The west wing represents two later additions, one in the 1840s, and further changes in 1885 carried out by its new owner Dr. Goldwin Smith. In 1911, the house became the property of the Art Gallery of Ontario and has operated as a museum since that time.
