Gilmore Junio became internationally known for his remarkable display of sportsmanship at Sochi 2014 when he gave his spot in the 1000m to teammate Denny Morrison, who had missed qualifying in that event after a fall at the Canadian trials. Morrison went on to win silver, a medal the two friends celebrated together. Earlier in the Games, Junio had finished 10th in his specialty, the 500m, ranking him as the top Canadian in the event. He had his big breakthrough in 2012-13 when he won his first World Cup medal, a silver in the 500m at Nagano in December. He ended the season ranked in the top 10 of the World Cup 500m standings and competed at his first World Single Distances Championships. Junio earned his first World Cup victory on November 15, 2013 when he tied for first in a 500m in Salt Lake City. In the 2016-17 season, Junio won a total of seven World Cup medals in the 500m, including two gold. In 2015-16 he finished third in the overall World Cup standings for the 500m.
