Before the start of the World Championship, each participating nation had to submit a list of players for its roster. A minimum of fifteen skaters and two goaltenders, and a maximum of twenty skaters and three goaltenders had to be selected. If a country selects fewer than the maximum allowed, they must choose the remaining players prior to the start of the tournament. After the start of the tournament, each team was allowed to select an additional two players, either skaters or goaltenders, to their roster, for a maximum roster of 25 players. Once players were registered to the team, they could not be removed from the roster.
