WHMIS includes a mechanism for ruling on claims for exemption from disclosure of confidential business information on labels and MSDSs as well as appeals to these rulings. Balancing workers' right-to-know with suppliers' need to protect genuine confidential business information was a fundamental consideration during the development of WHMIS.
Chemical identities and other information required by the Hazardous Products Act (HPA) and Canada Labour Code (CLC) can be claimed as a trade secret under the Hazardous Materials Information Review Act (HMIRA). The HPA is administered by Health Canada and the CLC is administered by Labour Canada. The trade secret mechanism is administered by the Hazardous Materials Information Review Commission.
What can be claimed as a trade secret is specified in section 11 of the Hazardous Materials Information Review Act (HMIRA):
Suppliers - A supplier may file a claim for exemption from disclosing:
(a) the chemical identity or concentration of any ingredient of a controlled product, or
(b) the name of any toxicological study that identifies any ingredient of a controlled product.
Employers - An employer may file a claim for exemption from disclosing:
The Hazardous Materials Information Review Regulations specify the four criterion against which the validity of a trade secret claim is assessed:
The exemption periods are as follows:
Generic in lieu of specific chemical identity - As specified in section 16 of the Hazardous Products Act, where a supplier is exempt from disclosing a specific chemical identity, "the supplier shall disclose on the MSDS or label the generic chemical identity of the controlled product or ingredient with as much precision as is consistent with the exemption."
Secondary supplier exemptions - Section 8.2 of the Controlled Products Regulations (CPR) sets out the obligations of a secondary supplier where the primary supplier has filed a claim for exemption or is exempted from disclosing information under the Hazardous Materials Information Review Act (HMIRA).
Information upon filing - Section 26 of the CPR sets out the requirement to disclose on the MSDS and, where applicable, the label, upon filing:
Information upon notice of decision - Section 27 of the CPR sets out the information to be disclosed upon notice of a decision:
The Hazardous Materials Information Review Act (HMIRA) establishes a Commission to rule on claims for exemption; assess the MSDS or label to which a claim relates; and administer an appeal process to these rulings. The Hazardous Materials Information Review Commission is an independent, quasi-judicial body whose President reports to Parliament through the Minister of Health Canada.
Specifically, under the authority of the HMIRA and the provincial and territorial occupational safety and health acts, the HMIRC is an administrative agency charged with carrying out the following mandate:
