The Leslie family built a large log house in 1826. The family became established and prospered, with George (the older son) becoming a noted horticulturalist in nearby Toronto, where he married into the prominent Davis family, and established one of the largest nurseries in the Dominion. The community that grew around his nursery became known as Leslieville, and Leslie Street in Toronto is named in his honour. Another son, Robert, became a noted architect and builder, having built several heritage buildings that survive in Mississauga today: Benares in Clarkson (1857), the Barber House near Streetsville (1862), and possibly the Hammond House near Erindale (1866). In later life, Robert was politically active in the Reform party and was said to be a close friend of Reform leader George Brown.

But back to the history of the log house.

In 1884, John Jr. sold the south half, along with the log house, to Christopher Rutledge, and in 1894 the north half of the lot passed to John Leslie Jr.’s son, also named George (1846-1910). The log house briefly returned to the Leslie family in 1924, when it was purchased by George’s son, Wilbert, and his wife Sylvia. They sold it in 1930 to Frederick Reeve, ending the long Leslie family association with the log house and the wider property. In all, the log house was in the Leslie family from 1826 until 1894, and from 1924 until 1930.
