The two athletes from Winnipeg Synchro Club will compete in the seniors solo event where each will perform two routines -- technical solos and free program.
"For Brittany and Marlene, this is a tremendous opportunity for them to gain international exposure and experience," said Winnipeg Synchro head coach Khadija Cutcher, who will accompany the athletes to in the competition. "When they try out for Canada's national team (this summer), they will have that experience behind them."
She said it is the second international competition as a soloist for Mueller, who last year competed at the U.S. junior national championships and the first for Desaulniers-Bernard.
The athletes were selected based on their scores at last month's provincial championships.
Also headed out of the country to compete are Holly Ediger and Carly Ayers, who are both 17-year-olds at the Vincent Massey Collegiate sports school.
The two, also members of Winnipeg Synchro club, will compete in the 2009 U.S. junior national championships.
