since when has music therapy been implemented as a self-regulated profession in canada?

Music therapy has been a self-regulated profession in Canada since about 1984. The profession's roots go back to the mid-1950s when music therapists were working independently across Canada, with the Canadian Music Therapy Association (now Canadian Association for Music Therapy, CAMT) being founded in 1974. However, formal self-regulation as a profession started around 1984.
