"prescribed" means prescribed by regulations of the Governor in Council;
Although "prescribed" means prescribed by Regulations of the Governor in Council, Section 27 provides that the Regulations may refer to any document as it exists when the Regulations are made and to certain specifically named documents as these are amended from time to time. Thus, the regulations incorporate into themselves other documents. Some of these, in turn, incorporate other documents. Currently, about 100 standards are referenced directly.
