When you want to enter an event like a CVI or world championships, the requirements are quite different than what you would expect at regular Canadian vaulting competitions. You will be entering on behalf of your country so this involves both Equine Canada and the International Equestrian Federation.
In Canada, we have Provincial and National Judges. Provincial Judges can judge provincial events as well as Equestrian Canada divisions up to and including Canter AA. National Judges can judge Provincial events and all Equestrian Canada divisions.
