Canada gathered 46 players on November 16 before the JVM at home for a selection camp with internal matches.
Everyone in the squad tested negative at the gathering, but this weekend came the first positive case when a leader tested positive.
On Tuesday, two players tested positive for covid-19 and the night before today, Swedish time, the Canadian Ice Hockey Association announced that all players and leaders were quarantined at the player hotel for 14 days from Monday.
The Junior World Cup will be played in a corona-secured bubble in Edmonton from December 25 to January 5. Federation captain Tomas Montén will announce the Swedish squad next Thursday.
