Kinghaven Farms is a horse racing stable that was founded in 1967 by Donald G. "Bud" Willmot. Located in King City, Ontario, north of Toronto, the success of the stable would see it expand to the United States with the acquisition of a 660-acre (2.7 km2) farm and training center near Ocala, Florida. In 1974, Bud's son began managing the farm's racing/breeding programs. In 2004, David Willmot announced that Kinghaven was shutting down its Thoroughbred operation, although he would continue to race a handful of horses in the following years.
