At the 1903 dispersal sale of Belmont's stable, Masterman was purchased by John Boden for $2,500.[1] Masterman was later given to the Canadian Breeding Bureau by Boden in September 1908 for use as a sire for cavalry horses.[2] Masterman was euthanized in June 1911 after breaking a leg[3] at a contract farm in Petite Cote, Quebec where he was being stabled.[4]
