Judged Single Contest Events are Full Contact and involves a roster of 9 officials, with each contest having a potential winner. Judged events may also have Exhibition (Full or Light Contact) contests mixed in to the same competition.
A physician must preside over an entire judged competition, starting at weigh-ins. Athletes participating in Judged Contests must have an Annual Medical Declaration (and blood work, if 16 years or older) completed prior to competition.
An Exhibition Event has no judged contests. Exhibition Contests follow different rules than judged competition; Exhibitions can occur with Full or Light Contact, use larger gloves, and do not have the same ring requirements as judged contests. An Exhibition Event involves a roster of 2 officials, with each contest resulting in a draw.
An Exhibition Event that has any Full Contact contests will require the attendance of a physician. An Exhibition Event that is made entirely of Light Contact contests may forgo a physician in favour of other trained medical personnel such as a nurse or paramedic.
Athletes participating in Full Contact Exhibitions must have an Annual Medical Declaration completed prior to competition. Laboratory blood tests are not required, as Exhibitions are stopped should any bleeding occur. Athletes competing in Light Contact Exhibitions do not require an Annual Medical Declaration.
