2021 World Junior Ice Hockey Championships

The 2021 World Junior Ice Hockey Championships (2021 WJHC) were the 45th edition of the Ice Hockey World Junior Championship. It began on December 25, 2020, and ended with the gold medal game on January 5, 2021. This marks the 14th time that Canada hosts the WJIHC. Due to the COVID-19 pandemic in Canada, it is hosted behind closed doors in Edmonton, Alberta, with no spectators admitted for any game.

Background
On December 6, 2018, it was announced that Edmonton and Red Deer, in the province of Alberta, would be the host cities. It will be the third time Edmonton has hosted the tournament, after previously hosting in 1995 and 2012, and the first to use Rogers Place as a venue.

Due to the COVID-19 pandemic, the IIHF cancelled all lower-division U20 championships on September 17, 2020 (there will therefore be no relegations this year), and announced that the top division tournament would be hosted solely by Edmonton using a "bubble" strategy similar to what has been used for the NHL's 2020 Stanley Cup playoffs in Edmonton and Toronto. This decision resulted in the elimination of Red Deer as the secondary host city of the 2021 tournament. All games will be held behind closed doors with no outside spectators. It was subsequently announced that Edmonton and Red Deer would host the 2022 tournament, and that Gothenburg, Sweden would be shifted from 2022 to 2024. The scheduling of the tournament may be adjusted to accommodate the single-venue format.

On October 19, 2020, the full schedule for the tournament was announced, with play beginning on Christmas for the first time since the 2004–05 edition.

On November 25, 2020, Hockey Canada suspended its selection camp and quarantined all players for 14 days (retroactive to November 23) due to two positive COVID-19 tests among participants.

Swedish head coach Tomas Montén, along with two assistant leaders and players William Eklund, Karl Henriksson, William Wallinder, and Albin Grewe from the Swedish preliminary roster, were forced to leave the team after being diagnosed with COVID-19 too close to the beginning of the championship.

Team Canada captain Kirby Dach sustained an injury in Canada's pre tournament game against Russia, and was ruled out for the rest of the tournament.

Germany did not have nine players available for its first two games because of COVID-19 protocols.
