Blenheim's Emma Negri won the hammer throw at the Royal Canadian Legion Youth National Championships by nearly nine metres.
The U16 National Champion competed as part of Team Ontario from August 11 to 13.
On Friday, she won the bronze in the discus.
On Saturday, she placed fourth in the shot put.
Sunday was her day to shine, as she won gold in the hammer throw with a distance of 58.12m.
The Royal Canadian Legion has been organizing and coordinating the National Youth Track and Field Championships for 44 years. The national championships are meant to give young Canadians a chance to compete against the best, develop confidence, and better understand the diversity of other sports-minded youth across Canada.
The competition was the end of Negri's outdoor season.
The teen intends to take a six-week break before she starts to prepare for the indoor season.
