Ontario Derby

The Ontario Derby is a Canadian Thoroughbred horse race run annually in mid-October at Woodbine Racetrack in Toronto, Ontario. A Grade III stakes since 2012, it is open to three-year-old horses. Raced over a distance of $1 1/8$ miles (9 furlongs) on Tapeta, the Ontario Derby currently offers a purse of Can$150,000.

Inaugurated in 1972 as the Colonel R. S. McLaughlin Handicap, the race was renamed the Ontario Derby for the 2003 running. Originally contested at $1 1/8$ miles, it was changed to its current $1 3/16$-mile distance in 1992.
