NORTH AMERICAN DANCE SPORT ALLIANCE In 1981 in the spirit of cooperation, the North American Treaty was created. This document was signed by the National Dance Council of America and representatives of the Canadian Dance Teachers Association, the CDTA., the Official professional body of Canada. The purpose was to open a more direct line of communication between the two countries, specifically in the areas of Rules, Competition date conflicts, and professional registrations. The North American Treaty was recast as “The North American Dance Sport Alliance” (NADSA) between Canada, represented by the Canadian Dance & Dance sport Council (CDDSC) and the United States, represented by NDCA, in November 2004. The new alliance document contains more specifically written points of agreement in the wider areas of the World Dance & Dance Sport Council, standing Joint Committee’s, etc..., as well as rules, regulations and communication, and makes provision for the possible inclusion of Mexico as a signatory to the Alliance at some future date.
