The system is defined in the IIHF Sport Regulations – two groups of five national teams. The seeding is done in a way to have two well-balanced groups.
The winner of this year’s championship in Canada is going to play in the first group together with the fourth, fifth, eighth and ninth team.
The second group is going to be made up of this year’s silver and bronze medal winners, the sixth and seventh teams and Germany, which is promoted after winning the second-tier 2019 IIHF Ice Hockey U20 World Championship Division I Group A.
Thus, it will be necessary to know the final standings of the current World Juniors in Canada. The two groups will therefore be revealed on 5th January 2019 after the gold medal game (6th January in the morning Central European Time).
But there is one thing that has already been set – Ostrava is going to host the group with the Czech team, whereas the other group is going to take place in Trinec.
