The Wonder Where Stakes is a Canadian Thoroughbred horse race run annually since 1965 at Woodbine Racetrack in Toronto, Ontario.
Held during the end of July/first week in August, it is the third leg of Canadian Triple Tiara series for Canadian-foaled three-year-old fillies.
Raced on Turf, the Wonder Where Stakes currently offers a purse of Can$250,000.
The race is named in honor of the champion filly, Wonder Where, Canada's 1959 Horse of the Year and a Canadian Horse Racing Hall of Fame inductee.
In 2007, Sealy Hill became the first filly to win the Canadian Triple Tiara since the series was created in 1999.
