If you have already purchased a ticket for the iihf world juniors 2021 edition and you have already received acknowledgment of the ticket, there are different options available for you. The first thing you should note is the 2021 edition will be played without fans, this means that you will not be able to use your ticket for that competition. What then are you going to do with the tickets? There are two options available for you. One is that you can use that ticket for the 2022 event which is to hold at the same venue.
The essence of holding it at the same venue is to mitigate the economic effect and that is to help those that invested heavily to recover their investment. So, if you have already purchased that ticket, then you can use it for the next edition which is to hold in 2022.
The other option available for you is to ask for a refund, and you would be given a refund once you meet the requirements.
