The next couple years Dufour-Lapointe found limited success on the World Cup tour though she still found herself on the podium several times. This led up to the 2013 World Championships, in her first matchup in the dual moguls she found herself 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. This was the first major title of her career and one that springboarded her into the Sochi Olympics in 2014.
