Loo, a snowboarder, is the first Canadian woman to compete at an Olympic Winter Games in the parallel giant slalom event. She joined Team Canada for the 2006 Games in Turin, Italy, where she finished in the 20th spot after a misjudgement in the qualifying round. For the 2002 Olympic Winter Games, she missed a qualification by just one-tenth of a second at a World Cup event. She is now training toward a berth at the Games in Vancouver in 2010.

She is a veteran leader on the national snowboard team. Loo has competed in parallel giant slalom and giant slalom at each World Championship since 1999 (they are held every other year). Most recently, she finished eighth in parallel slalom and 12th in parallel giant slalom at the 2009 World Championships in Gangwon, Korea. Loo is a constant figure at each Canadian national snowboard championship and is a multiple national champion in parallel giant slalom, including 2009 champion.

In parallel giant slalom, Loo won a World Cup bronze medal in 2009 in the United States as well as bronze in 2006 in Italy – marking the first such medal for a Canadian woman snowboarder. Over her career, she has collected 13 top-10 finishes at World Cup events and many first-place finishes at Nor-Am Cups.

She is a member of the AthletesCAN board of Directors. For the International Paralympic Committee, Loo volunteers as a seeing-eye guide. Loo graduated from the University of British Columbia with a bachelor of commerce and secured a Chartered Accountant designation in 1998.
