Crosby went on to compete in two World Junior Championships with Team Canada's under-20 team. When he was named to the team in December 2003, he became the fifth 16-year-old to represent Canada at the tournament, following Jay Bouwmeester, Jason Spezza, Eric Lindros and Wayne Gretzky. Competing in the 2004 World Junior Championships in Helsinki, he then became the youngest player to score a goal in the history of the tournament at 16 years, 4 months, and 21 days when he scored against Switzerland in a 7–2 win. This record would last until the 2012 World Juniors when Aleksander Barkov of Finland scored a goal aged 16 years, 4 months. Crosby finished the tournament with two goals and three assists in six games, helping Canada to a silver medal finish. The following year, he returned for Canada at the 2005 World Junior Championships in Grand Forks, North Dakota. He improved to six goals and three assists as Canada earned gold. Crosby stated the following year that his most memorable hockey moment was winning his World Junior gold medal.
