Britt, I believe that any karting event held in Canada and hosted by an ASN Canada affiliated club (i.e. West Coast Kart Club) is required to be run under ASN Canada insurance.
And I’m also pretty sure that there is an agreement in place where even if the event is sanctioned by IKF (sanctioning defined as: IKF classes, IKF technical rules, and IKF sporting/competition rules apply), ASN Canada’s insurance (and insurance-related rules – driver’s safety equipment, track safety, etc.) apply.
