Dufour-Lapointe was the runner-up and silver medallist at the FIS Freestyle World Ski Championships 2011 as well and placed fifth at the 2010 Olympic Games.

In the dual moguls event, she advanced to the final against teammate and idol, Jennifer Heil.

Heil had nothing but kind words to say for the rising star, saying, "It was so cool to go against Chloe in the final.

This led up to the 2013 World Championships; in her first matchup in the dual moguls, she was up against sister Justine who she would beat 19–16.

From here, Dufour-Lapointe went on a run and made it to the final, where she edged out a World Championship victory by a single point.
