King's Plate

The King's Plate (known as the Queen's Plate from 1860 to 1901 and 1952 to 2022) is Canada's oldest thoroughbred horse race and the oldest continuously run race in North America, having been founded in 1860. 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 is the first in the Canadian Triple Crown, typically taking place each summer at Woodbine Racetrack in Etobicoke, Ontario. The event was scheduled in June or July until 2020, when it was postponed to September, due to government-imposed restrictions in place through the COVID-19 pandemic. Since 2021, Woodbine ran the Queen's Plate, and now runs the King's Plate, in August.

The race's name reflects the title of the reigning Canadian monarch, following on Queen Victoria's donation of the first cup. The Woodbine Entertainment Group, which owns and operates the event, announced in December 2022 the race would be renamed the King's Plate, following the accession of King Charles III on 8 September 2022.

In 1859, the then-President of the Toronto Turf Club, Sir Casimir Gzowski, petitioned Queen Victoria to grant a plate for a new race in the Canada West (today Ontario). With the monarch's approval, the first Queen's Plate was run on 27 June 1860, at the Carleton racetrack in Toronto, with the prize of "a plate to the value of 50 guineas". Despite the name, the winning owner is presented with a gold cup, rather than a plate.

The race was originally restricted to three-year-olds bred in Canada that had never won a stakes race and was run in heats, with a horse having to win two heats to be declared the winner. The race conditions have since evolved; heat racing was discontinued in 1879 and, around the same time, the race was opened to stakes winners (some early records are incomplete). For many years, the race was open to older horses and, in the early 1900s, was even open to two-year-olds. The King's Plate is currently restricted to three-year-olds foaled in Canada. The owner must pay a nomination fee ($500 in 2018) in February, a second subscription fee ($1,500 in 2018) in May, and a final entry fee ($10,000) prior to the race.

The first four renewals were run at Carleton racetrack. After that, the Queen's Plate became a "movable feast", with politicians from all over modern-day Ontario vying to host the race in their constituency. Fifteen different race tracks hosted the race over the next two decades, with distances varying from one to two miles. In 1883, the race moved to Old Woodbine, located in eastern Toronto along Lake Ontario. The race continued to be held at Old Woodbine until that track was replaced by "New" Woodbine in northern Toronto in 1956. The race has been run at Woodbine ever since. In 2006, Woodbine changed the track surface for the main track from natural dirt to a synthetic surface known as Polytrack. In 2016, the surface was changed to Tapeta. Because of the change in racing surfaces, Woodbine maintains several sets of track and stakes records. The fastest time for the race on the original dirt surface at the current 1+1⁄4 mi (2 km) distance is 2:01 4/5, set by Kinghaven Farms' Izvestia in 1990. The current stakes record (the fastest all-time) is 2:01.48, set by Moira in 2022 on Tapeta.

In 1902, the year after Victoria's death, the race became the King's Plate, after her successor, Edward VII. It became the Queen's Plate again during the reign of Elizabeth II (1952–2022). In 2022, it reverted to the King's Plate upon the accession of Charles III.

Horses owned by Windfields Farm have won the Plate eleven times, but the most successful was the stable owned by Joseph E. Seagram, a prominent distiller from Waterloo, Ontario. Seagram's stable won the Plate on twenty occasions between 1891 and 1935 including eight times in a row between 1891 and 1898, and ten times in eleven years from 1891 to 1901.
