 The program was abandoned after two years, and it was more than a decade before the legislative authority for its graduates to practice was put into place.An alternative program which provided 1,400 hours of training at the community college level prior to commencing employment was then tried, and made mandatory in 1977, with formal certification examinations being introduced in 1978.Similar programs occurred at roughly the same time in Alberta and British Columbia, with other Canadian provinces gradually following, but with their own education and certification requirements.
