Thank you for the question.
In fact, it's been 20 years. It was in 1988—on October 31—that WHMIS first came into being, and that's when we were created as the commission to look at trade secrets.
I would say to you that not much has changed in terms of the fundamental system, which I think is a wonderful thing. The fundamental right of workers to know about the hazards they're working with and industry's right to protect their trade secrets have remained fundamental cornerstones of the WHMIS system.
What has changed is global harmonization--multinational companies and the need for Canada to keep up with what the other countries are doing. So in the last ten years we've been working with other countries—and domestically—in looking at the global harmonization of hazard classification, and have been inching forward towards bringing that to fruition and being able to incorporate those new harmonized standards into the new WHMIS standard. So of course, by extension, our commission will then adopt those WHMIS standards to apply to our claimants.
But other than that, I think technology, as with all things, has made everyone's job in compliance a little more challenging.
