Renee Robertson, 17, and Gillian Hinton, 16, both of Mississauga, also won multiple medals at the tournament.
Bratic won gold in the 18-over women's 61-kilogram kumite (sparring) division, by defeating Fredericton's Katie Campbell, and in the age 18-20 Junior women's 61-kilogram kumite division.
She also captured silver in the women's open kumite and a bronze medal in the age 18-20 Junior women's kata (forms).
Last year, Bratic and her sister, Nadja, became the first Canadians to medal at the World Junior and Cadet Karate Championships, which were held in Istanbul, Turkey.
Bratic is currently in Poland, competing at the 6th World University Karate Championships.
Robertson and Hinton, who've been friends since their days as Brownies in the Lorne Park-Clarkson area, have emerged as strong karate competitors in Ontario.
Little did they realize that 10 years after having first met, they'd be standing on the medal podium at the Canadian championships.
Hinton, a first-degree black belt, picked up a pair of bronze medals at the meet and Robertson grabbed three bronze.
Robertson, a four-time provincial champion in kumite and kata, picked up her medals in kata, kumite and team kumite.
Hinton, ranked second in the province among girls aged 16-17 in sparring, was a bronze-medal winner in kumite and team kumite.
The two are students at the Academy of Yoshukan Karate in Mississauga. They hope to be back at the national finals next year in Calgary.
