The Queen's Plate (known as the King's Plate from 1901 to 1952) is Canada's oldest Thoroughbred horse race, having been founded in 1860. It is also the oldest continuously run race in North America. It is run at a distance of 1+1⁄4 miles (2 kilometres) for a maximum of 17 three-year-old Thoroughbred horses foaled in Canada. The race takes place each summer at Woodbine Racetrack in Etobicoke, Ontario. It is the first race in the Canadian Triple Crown.
