In the opening race of the 2006-07 season, a 15 km individual competition in Östersund, Sweden, Kocher finished third, becoming the first Canadian biathlete to make the podium in a top-level international event since Myriam Bédard ten years earlier. After a two year period where she struggled with illness, Kocher took a fourth place in a pursuit at the third meeting of the 2009-10 season in Pokljuka, Slovenia, shooting 20 out of 20 targets in an event for the first time, having already taken a tenth place in the sprint at the same meeting. At the 2014 Winter Olympics in Sochi, Russia, she was part of the Canadian team that finished eighth in the women's relay, the best ever Canadian finish in that event.
