The 2010 World Junior Hockey Championships, was the 34th edition of Ice Hockey World Junior Championship. The tournament was hosted by Saskatoon and Regina, Saskatchewan, Canada, from December 26, 2009, to January 5, 2010. Saskatoon had hosted the tournament once before, in 1991. The medal round, as well as all Canada's preliminary round games, took place in Saskatoon at the Credit Union Centre. The arena underwent renovations and upgrades before the 2010 tournament, including an increase in capacity. Other games were played at the Brandt Centre in Regina, which also received upgrades. In addition, pre-tournament exhibition games were held in other towns and cities throughout the province as well as Calgary, Alberta. In the gold medal match, the United States defeated the pre-tournament favourites and host country Canada 6–5 in overtime on a goal by John Carlson to win their second gold medal and first since 2004, ending Canada's bid for a record-breaking sixth consecutive gold medal.
