Often called the Salem Eckardt House, this was the home of his brother, Andrew, Unionville's first postmaster and a participant in the 1837 Rebellion. Salem, a farmer, farm implement manufacturer, builder, tax collector, and auctioneer, planted maple trees along Main Street and is believed to have added the gables and verge-boards to the house.
The house was purchased in the late 1950s by Kathleen McKay (nee Gormley) who hosted Fred Varley, an original member of the Group of Seven. Fred Varley lived out as a guest of Donald and Kathleen McKay. Varley painted his last works in the basement studio, overlooking the Rouge flood lands to the east. His name was given to the first large residential subdivision in Unionville, Varley Village, in the mid-1960s (beginning suburbanization). Varley died in 1969.
