Canada men's national junior ice hockey team

The Canadian men's national under-20 ice hockey team is the ice hockey team representing Canada internationally in under-20 competition. Their primary participation in this age group comes at the International Ice Hockey Federation's World Junior Championship, held annually every December and January. The team also participates in various exhibition matches and occasional exhibition series, such as the 2007 Super Series against their Russian counterparts, an eight-game exhibition series commemorating the 35th anniversary of the 1972 Summit Series.

The Canadian junior team is the most successful in the world, having medalled in 34 of 46 events held since 1977, winning a record 20 gold medals. Its success can be traced back to the formation of the Program of Excellence in 1982 by the Canadian Amateur Hockey Association, which created the first true national junior team. Since that time, Canada has won 20 of 42 World Junior championships – including five in a row on two occasions, 1993–1997 and 2005–2009.
