The Optimist International Under-18 Curling Championship is an invitation-only bonspiel held annually in Canada. The event affords developing curlers under the age of 18 the opportunity to gain international experience in a friendly, competitive environment. In addition, there is typically a half-day of training by some of Canada’s top instructors.
USA Curling invites applications from junior teams throughout the United States each year. Teams are selected based on strength of the applicants and potential for success at the international level.
