The Pyeongchang 2018 Olympic silver medallist and 2017 world champion clinched victory with a first-run score of 78.31 points and then went onto improve her mark to 79.56 on the Winsport Slopestyle course at Canada Olympic Park.

"First run, everything went well," Blouin was reported as saying by the Canadian Broadcasting Corporation. 

"I couldn't have done that run better, so I had to upgrade that last jump and I did. 

"Yeah, I'm stoked that I just landed both runs.

"It's not too big of a course – it's not too big, not too mellow. 

"It's just perfect and when it's sunny, it's so much fun to ride."

Blouin occupies second place in the FIS Snowboard Slopestyle World Cup standings for women with 2,200 points.
