Janice Bremner got her start in synchronized swimming in the late 1980s, but participated in her most successful tournaments during the 1990s. In 1994, alongside Lisa Alexander, Karen Clark, Karen Fonteyne, Cari Read, Kasia Kulesza, Erin Woodley and the non-Olympian Carrie DeGuerre, she won a silver medal in the team event at the World Aquatics Championships. Her next major podium finish came the following year, at the Pan American Games, where she finished second again in the team category. Then, with Christine Larsen, Sylvie Fréchette, and Valérie Hould-Marchand replacing DeGuerre, she won another silver medal in the event at the 1996 Summer Olympics. Shortly after the Games Bremner retired from active competition and entered the University of British Columbia. She graduated in 1999 and began working in fitness and health education. In 2010 she helped carry the Olympic Torch on its way to the Winter Olympics in Vancouver, British Columbia. In 2011 she became president of Synchro BC and earned her master of education from Simon Fraser University where, as of 2012, she is working towards a Ph.D.
