Placed in Group A are Team Canada, Team Czech Republic and Team USA, plus Team Europe, a pan-European roster of players from birth countries outside of the Czech Republic, Finland, Russia and Sweden. The four teams in Group B are Team Finland, Team Russia, Team Sweden and Team North America, a selection of the top players from Canada and the United States who are 23 or under as of Oct. 1, 2016.
The top two finishers in each of Group A and Group B will advance to the Semifinals (Sept. 24-25), where each qualifier will face an elimination game against a team from the other Group. The two Semifinal winners will meet in the Final, a best-of-three series on Sept. 27, Sept. 29 and, if necessary, Oct. 1.
