There's a variety of reasons for that, including the fact that WHMIS is built on a tripartite system, whereby we work very collaboratively with industry, employers, and our provincial and territorial counterparts. The idea is that we would need to consult more broadly before bringing in these sectors.
Furthermore, as I've just described, there are legislative and regulatory requirements that we need to be conscious of in moving these forward. We need to make sure that we're bringing them forward in such a way that we're not causing harm to other pieces of legislation or other disclosure requirements. We do need to do more research before we bring them in.
