That was for 2014.
and
A) All riders must obtain a CSBK Membership prior to any track participation at a CSBK event. Please note that racers must have an
approved and valid racing license from one of the noted sanctioning groups. Please see csbk.ca.
B) Competitors who are currently ranked as Novice within their Regional series, will be classified as National Amateurs.
C) Competitors who are currently ranked as Amateurs within their Regional Series, will be classified as National Amateurs, unless that
competitor has placed in the top three in a final overall season Series Points Standings, in a class for 600cc or larger, production based,
multi cylinder (greater than twin) machinery. Then they will be subject to classification of rider level status by CSBK.
E) Competitors who are currently ranked as Pro or Expert status within their Regional Series, will be subject to classification of rider level
status by CSBK based on a review of previous racing experience.
If it's CSBK I believe you need a racing license from one of the sanctioned series. RACE and SOAR at the least, I think.
