The Canadian Association for Sandplay Therapy (CAST) has been a National Society member of the International Society for Sandplay Therapy (ISST) founded by Dora Kalff, since 1998. CAST's role as a national society is to promote the development of sandplay in Canada by providing training, offering opportunities for professional exchange, and maintaining guidelines for professional practice. Successful training candidates will achieve international certification with ISST.
CAST's focus in recent years has been to become recognized as the centre for sandplay training in Canada, both by expanding its programmes and by integrating its standards of practice with the emergent regulation of psychotherapy in various provinces. It is important to note that CAST is not a regulatory body. Certification by CAST/ISST requires that any provincial regulations regarding the practice of psychotherapy are adhered to.
A pivotal role in the history of CAST was played by Dr. Nehama Baum of Toronto, who brought together a group that felt "called to" Sandplay Therapy. She organized the first meeting of CAST in September 1993, at which time the association established its organizational structure, goals, membership guidelines, board of directors, and training guidelines.
CAST's inaugural conference, Sandplay: A Magical Journey, took place in 1993. Distinguished faculty included Linda Bath (US), Nehama Baum (Canada), Paola Carducci (Italy), Yvonne Federer (then Canada, now Switzerland), Martin Kalff (Switzerland), Adriana Mazzarella (Italy) and Claudio Risé (Italy). The European presenters at the inaugural conference agreed to serve as honorary board members, along with Kay Bradway and Estelle Weinrib (US) who were unable to attend the conference.
