Greenwood Raceway was a horse racing facility in Toronto, Ontario, Canada.

Northern Dancer was a Thoroughbred that, in 1964, became the first Canadian-bred horse to win the Kentucky Derby. After being retired from racing, he became one of the most successful sires of the 20th century. He is considered a Canadian icon and was inducted into the Canadian Sports Hall of Fame in 1965. Induction into the Racing Hall of Fame in both Canada and the United States followed in 1976. As a competitor, The Blood-Horse ranked him as one of the top 100 U.S. Thoroughbred racehorses of the 20th century. As a sire of sires, his influence on the breed is still felt worldwide.
