Canada's Valérie Grand'Maison continues to dominate in the pool, capturing her third gold medal of the Beijing Paralympics with a win in the women's 100-metre freestyle for S13 visually impaired.

Montreal's Grand'Maison won Wednesday's race in a world record time of 58.87 seconds, lopping almost a second off her own record.

Canada came close to its second sweep of the medals as Chelsea Gottell earned the silver in one minute 26 seconds and Kirby Côté touched the wall fourth in 1:00.95. The three won gold, silver and bronze in the 100 butterfly for S13 visually on Sunday.

American Kelley Becherer took third in 1:00.46.

Grand'Maison has been the star of the Beijing Paralympics for Canada. The 19-year-old swimmer smashed the world record in the 400-metre freestyle for the S13 visually impaired Monday, outdistancing Russian Anna Efimenko by 8.73 seconds.

Grand'Maison, who began losing her eyesight at 12 due to macular degeneration, still holds world records in the 100, 200, 400 and 800 freestyle events, plus the 400 individual medley.

She won five gold medals at the 2006 world championships.

Gottell earned her third medal in Beijing — two bronze earlier in the week. The Hamilton resident won a gold in the 100 backstroke and three more bronze medals at the Athens Paralympics.

Her goal in Beijing is to capture a gold medal and break the world record in the 100 backstroke. Gotell is also a world-record holder in the 50-m and 200-m backstroke.

Côté, meanwhile, earned her silver medal on Sunday. The Winnipeg native, captured five gold medals at Athens in 2004 and has seven golds in the last two Games.
