form of level placement). The Canadian University synchronised swimming League (CUASL) is intended for Canadian Swimmers who wish to continue their participation in the sport during their university studies, as well as offering a "Novice" category for those new to the sport. Traditionally, the top teams hail from McGill University, the University of Ottawa, and the University of British Columbia. Men's and mixed competition Some international, national and regional competitions allow men to compete, and the Fédération internationale de natation (FINA) introduced a new mixed duet competition at the 2015 World Aquatics Championships. In the late 19th century, synchronised swimming was a male-only event. However, in the 20th century it became a women's sport, with men banned from many competitions. In the U.S., men were allowed to participate with women until 1941, when synchronised swimming became part of the Amateur Athletic Union (AAU). The AAU required men and women to compete separately, which resulted in a decline of male participants. In the 1940s and 1950s, Bert Hubbard and Donn Squire were among the top US male competitors. In 1978, the U.S. changed their rules to allow men to once again compete with women. Rules in other countries varied; in the UK, men were prohibited from competing until 2014, while in France, Benoît Beaufils was allowed to competed at national events in the 1990s. American Bill May was a top competitor in the late-1990s and early-2000s. He medalled in several international events, including the 1998 Goodwill Games. However, male competitors were barred from top competitions, including the World Aquatics Championships and the Olympics. However, at the 2015 World Aquatics Championships, FINA introduced a new mixed duet discipline. Both May and Beaufils returned from decade-long retirements to represent their countries. Among their competitors were Russian Aleksandr Maltsev and Italian Giorgio Minisini, both over 15 years younger than May and Beaufils. Pairs from ten countries competed in the inaugural events. The 2016 European Aquatics Championships was the first time men were allowed to compete at the European Championships. While men are allowed in more events, they were still barred from competing in the 2016 Summer Olympics. FINA did propose adding the mixed duet competition to the 2020 Summer Olympics. In 2022, FINA allowed men to compete as soloists at the 2022 FINA Artistic Swimming World Series and the 2022 FINA World Junior Artistic Swimming Championships and LEN allowed men to compete as soloists
