The IIHF announced the cancellation of the last three tournaments in the 2020 U18 World Championship calendar. The Top Division, Division I Group A and Division I Group B join the other U18 tournaments that were cancelled just over a week ago. So we now have to wait until 2021 for some U18 hockey I guess.

Teams affected by the cancellations include:
- Top division (Plymouth and Ann Arbor, United States): Belarus, Canada, Latvia, Sweden, Switzerland, Czech Republic, Germany, Finland, Russia, United States
- Division I Group A (Spišská Nová Ves, Slovakia): Slovakia, Denmark, France, Kazakhstan, Norway, Japan
- Division I Group B (Asiago, Italy): Austria, Hungary, Italy, Poland, Slovenia, Ukraine
