WINDSOR, Ont. -- Canada raced to a pair of silver medals at the world short-course swimming championships on Wednesday.

Kylie Masse of LaSalle, Ont., picked up one in the women's 100-metre backstroke, the event in which she won bronze at last summer's Rio Olympics.

And Yuri Kisil, Markus Thormeyer, Michelle Williams and Sandrine Mainville raced to second place in the mixed 4x50 freestyle relay.

Penny Oleksiak of Toronto, whose four-medal performance was one of the highlights of the Rio Games, broke her own Canadian record in the 100 freestyle in both the heats and semifinals Wednesday.

She swam 52.19 seconds in Wednesday night's semifinals.

Masse, Oleksiak, Williams and Kelsey Wog of Regina narrowly missed a medal in the 4x50 medley relay earlier in the night.

Canada has three medals in the meet's first two days. Taylor Ruck kicked off the medal parade on Tuesday, winning bronze in the women's 200 freestyle.
