Sibling rivalry can be a source of contention within families - but for the Dufour-Lapointe sisters it has only been an inspiration.
Maxime, 24, Chloe, 22, and Justine, 19, will all be competing together as part of the Canadian national mogul team at this year's Winter Olympics in Sochi.
Ranked fifth, third and second respectively in their sport worldwide, Chloe paved the way for her older and younger sisters when she represented Canada at the 2010 Vancouver Games.
The BBC spoke caught up with them in Montreal just before they headed to Russia.
