Serwa won a national championship in 2009 at
Canada Olympic Park in Calgary, defeating world champion
Ashleigh McIvor. Serwa won her first world cup event on January 13, 2009, at the
Alpe d'Huez course after these finals were canceled on the
2009–10 Freestyle Skiing World Cup. Serwa won her first outright world cup race later that season at
Lake Placid on January 24, 2010. At the
2010 Winter X Games two weeks before the Olympics, Serwa managed to win a bronze at the famous cash event, fellow countrywoman
Ashleigh McIvor had finished second. Serwa was a member of the Canadian Olympic team that competed in
Vancouver in her home province of British Columbia. Serwa's bronze at the
Winter X Games and third overall ranking on the world cup put her in as a medal favourite at the Olympics in Vancouver. She advanced to the semi-finals, but finished third in her heat and did not make the medal final. However, she competed in the "small final", which she won, finishing fifth overall. During the next season Serwa won the gold at the
X Games with a dramatic finish flying 150 feet in the air and crashing out badly injured, but the champion. Serwa carried her X Games winning momentum into the
2011 World Championships. There she qualified as the fourth fastest skier, Serwa then went on to finish first in the final ahead of teammate
Julia Murray. With the victory she completed the seasonal sweep of the two biggest ski cross events in the world. On February 21, 2014, Serwa won silver in women's ski cross during her second Olympics, finishing behind gold medalist and Canadian teammate
Marielle Thompson. Serwa suffered a training accident in December 2016 and considered retirement from ski cross, but ultimately returned to the sport following knee surgery. She subsequently earned a place on Canada's ski cross team for the
2018 Winter Olympics in
Pyeongchang. Serwa went on to win the gold medal in women's ski cross, with her teammate
Brittany Phelan winning the silver medal. On July 4, 2019, Serwa announced her retirement from competitive ski cross, after ten years on the national team. ==Personal life==
