2017 World Junior Ice Hockey Championships
The 2017 World Junior Ice Hockey Championships was the 41st edition of the Ice Hockey World Junior Championship. The main tournament was co-hosted by the Bell Centre in Montreal, Quebec and Air Canada Centre in Toronto, Ontario. This was the 14th championship that Canada had hosted. Montreal and Toronto also jointly hosted the 2015 edition. The tournament consisted of 30 games between 10 nations.
Group A preliminary games, as well as the medal rounds, were hosted by the Bell Centre in Montreal. The Air Canada Centre in Toronto hosted preliminaries in Group B, including the host country of Canada. The tournament also initiated several year-long celebrations, the 375th anniversary of Montreal's founding; the 100th anniversary of the National Hockey League's founding in Montreal; the 100th anniversary of Hockey Canada's origins; the 50th anniversary of Montreal's Expo 67; the 150th anniversary of Canadian confederation; and the 100th anniversary of the Toronto Maple Leafs. The Maple Leafs had planned to make the WJHC the centrepiece of their 100th-anniversary celebrations.
The event was organized by Hockey Canada, Hockey Québec, Ontario Hockey Federation, Montreal Canadiens, Maple Leaf Sports & Entertainment and Evenko. Montreal and Quebec provided C$1 million and C$2 million in funding, respectively, for both the 2015 and 2017 editions.
For the first time in the history of the event, the defending champion had to compete in the relegation round. Latvia was relegated to Division I-A for 2018 by merit of their tenth-place finish.
