Mitch Marner was a late cut for the 2015 edition of the tournament, as Team Canada opted to take Leafs legend Frederick Gauthier instead. But Marner earned a spot in 2016, and by far was one of Canada's best players.
While Team Canada ended up with a disappointing 6th-place finish, Marner did more than his part, scoring 4 goals and 6 points in 5 games.
William Nylander represented the "Tre Kronor" twice at the World Juniors, starting in 2015, where he had a very strong 10 points in 7 games.
Nylander looked to continue his strong performance into the 2016 tournament, but unfortunately, it got cut short due to an injury in the opening game.
Max Domi only played at one World Juniors, but oh boy was he electric to watch.
Representing Team Canada in the 2015 tournament, Domi scored 5 goals and 10 points en route to a dominating gold-medal-winning effort from the Canadians.
Domi was named the tournament's top forward for his efforts.
Knies represents one of the more recent appearances at the World Juniors for Toronto Maple Leafs prospects, representing Team USA in 2022, notching 3 assists in 5 games.
His American squad unfortunately bowed out in the quarterfinals in an upset loss to Team Czechia.
