 The most famous horse from Canada is generally considered to be Northern Dancer, who after winning the Kentucky Derby, Preakness and Queen's Plate in 1964 went on to become the most successful Thoroughbred sire of the twentieth century; his two-minute-flat Derby was the fastest on record until Secretariat in 1973.The only challenger to his title of greatest Canadian horse would be his son Nijinsky II, who is the last horse to win the English Triple Crown.Woodbine Racetrack (1956) in Toronto is home of the Queen's Plate (1860), Canada's premier Thoroughbred stakes race, and the North America Cup (1984), Canada's premier Standardbred stakes race.
