We haven't looked in detail at the CGSB catalogue to see if there are duplicative standards, but I can say that I've heard some anecdotal evidence that in Canada we are having to undergo two tests for products that are perfectly fine with one test in the U.S.
One example of that would be for the glass doors in your shower stalls. They need to be tested twice to be used in Canada, once with an ASTM test, and once against a CGSB standard. The standard was developed and has not been updated since 1990. In my view, a standard that is many decades old has diminished value, and yet we need to pay for those shower doors that have the two logos.
In other sectors, we're being told that the cost of certifying a mature product can be between 2% and 4% of the cost of the product that you pay for. So if the same shower door is being used in Canada and the U.S. but it needs to have two certifications in Canada, then there's a contributor to the price gap. That hasn't been documented systematically, but I would say that anecdotal evidence shows that there may be instances where a CGSB standard would lead us to having multiple certifications with very old, outdated standards.
