The Grange was built about 1817 for lawyer and merchant D'Arcy Boulton Jr. in an area of exclusive residential estates in the town of York, now Toronto. One of the few such houses to survive, its symmetrical five-bay façade and central pediment reflect the conservative influence of the 18th-century British classical tradition. The west wing represents two later additions, one from the 1840s and the other built in 1885 for the new owner, eminent public figure Goldwin Smith. In 1911, through the bequest of his wife, Harriette, the house became the property of what is now the Art Gallery of Ontario.
