(born December 8, 1957 in Scarborough, Ontario
) is a Canadian Thoroughbred horse trainer
and the first woman trainer to win the Queen's Plate
, the oldest thoroughbred horse race
and Canada's most prestigious race.
Ms Carroll undertook an equine
studies course at Humber College
before embarking on a racing career in 1975 in the employ of Canadian Horse Racing Hall of Fame
trainer Mac Benson
at Windfields Farm
. She worked as an assistant trainer until 1994. She had early success with Tethra
, owned by members of the prominent Eaton family
In recent years she has been one of the leading trainers at Woodbine Racetrack
and has won a number of graded stakes races
both in Canada and in the United States
Prior to the 2006 winning run, she had had one horse compete in the Queen's Plate. Her 2006 entry, Edenwold
, earned the Sovereign Award
as Canada's top two-year-old in 2005, but observers of the sport believed the colt could not sustain the Queen's Plate distance of a mile and a quarter. Ridden by jockey Emile Ramsammy
, her winning horse was considered a long shot, going off at 16-1odds in the $1 million Grade I Queen's Plate.
Carroll is the second female trainer to take Canada's most prestigious race for three-year-old fillies, the Woodbine Oaks
with Inglorious in 2011.
