Hamelin was in the lead for the majority of the race, but made brilliant passes on Chinese skaters Tianyu Han and Dequan Chan earlier on and then on Han and American J.R. Celski with six laps remaining.
Hamelin's passes were extremely slick and smooth, and a major reason why he was able to execute such outstanding moves was because of his experience.
Tianyu Han of China won the silver medal and Victor Ahn of Russia won the bronze medal.
Hamelin won the second gold medal for Canada at the 2014 Olympic Winter Games in Sochi and fifth medal overall. Team Canada is in second place in the overall medal standings. Norway leads with seven medals.
Hamelin has also won his fourth career medal (gold in the 500m and 5000m relay at the 2010 Olympic Winter Games in Vancouver and a silver medal in the 5000m relay at the 2006 Olympic Winter Games in Turin).
He will be a legitimate medal contender in the men's 1000m (February 15, 5:20 a.m.), the men's 500m (February 21, 10:45 a.m.) and the men's 5000m relay (February 21, 11:15 a.m.).
