[1] Unlike the provincial and national championships in Ontario and Canada, teams from a variety of countries apply rather than qualify to compete in the World Broomball Championships and there is no need to compete for entry.

The vast majority of broomball players and teams are based in Canada or the USA and as a result most of the championships to date have been held in this part of the world.

Traditionally World Championships see teams enter from Canada, United States, Italy, Japan, Switzerland, France and Australia.

Teams representing Austria, Slovenia and Germany, have also taken part but due to limited player numbers and broomball programs these nations are not able to attend each World Championship.

The World Broomball Championships (WBC) were initially known as the, "Challenge Cup".
