Élissa-Marie started amateur boxing in October 1998 as an 11-year-old girl. Only 3 three years later, when she was all of 14 years old, she was named Canadian champion and kept this title for 4 consecutive years, until 2005. She also held the title of Quebec champion 11 years running. In 2007, she participated in the Pan-American Games in Ecuador where she won the silver medal. Over the course of her boxing career, she competed on the international stage, participated in more than 80 fights and was considered one of the ‘top ten’ female boxers in the world when she decided to hang up her gloves and retire from active competition after being disappointed by the decision to remove female boxing from the 2008 Olympic Games in Beijing.
In 2010, at the official end of her boxing career, Élissa-Marie decided to share her experience with young regional recruits. She started her new role as a trainer at the Club de Boxe de Jonquière (CBOJ) and played an important part in developing the club until 2017. In November 2018, thanks to her experience as an athlete and trainer, Élissa-Marie was approached by the Quebec boxing federation to train the Quebec women’s team in Zielonka, Poland, for an international competition involving athletes from Poland, Canada and a few other European countries. It was an offer she couldn’t refuse and a golden opportunity to come back to her first love, boxing, for the space of one week. She was able to end her training career while realizing her dream, coaching the ‘cream of the crop’ on the international stage.
