No, actually, there aren't any lists of products that would be excluded, other than that the product must be a controlled product as defined by the Hazardous Products Act and the controlled products regulations. There are products excluded from that sphere of responsibility, such as pesticides and cosmetics, and those are listed in part II of the Hazardous Products Act.
If you have a controlled product or a hazardous product that meets that definition and you have an ingredient concentration or identity that you don't want to disclose, then you can come to the commission--again, as long as you meet the test of the economic criteria and you submit the accompanying MSDS with it.
