Yes. A significant number of standards are indeed outdated, meaning, they have outlived their technical usefulness. A National Standard of Canada must be reviewed at least every five years. In the case of non-national standards, the review period can vary. SDOs have made a major effort in this regard, perhaps a bit forced into it by the Standards Council of Canada.
Be that as it may, when the Standards Council of Canada audits an SDO, the verification process is rigorous. Every single time, it examines what the organization has done to really keep its catalogue up to date. That means ensuring that no national standards of Canada are past the five-year review period and that other standards have been reviewed within a five- to ten-year window.
I can tell you that the Standards Council of Canada auditors have really been making a tremendous effort when reviewing SDOs. The number of SCC-accredited standards development organizations now stands at eight.
