No. I think CGSB was a very useful organization 40 or 50 years ago when it was closely integrated with the procurement system of the Government of Canada. It developed standards and specifications that were then tested by Public Works, because Public Works had laboratories. Those laboratories were closed in 1977. Since then the value of the catalogue has diminished and there are up-to-date alternative standards out there that can be used and are being used by Canadian regulators and industry.
