Registration procedures

You must download and save PDF forms to your computer before filling them out.

The claims registration function includes the receipt of the Claim for Exemption Form, a preliminary check of the safety data sheet (SDS) (and label, for certain employer claims) for the hazardous product in question, and the collection and verification of fees. A unique Registry Number is then assigned to the claim and notification is sent to the claimant, indicating the Registry Number and the date of filing. The claimant must then place, along with the date of filing, this Registry Number on the relevant SDS/label, in place of the claimed confidential business information (CBI) (also called trade secret information).

The Registry Number is normally issued within seven days of receipt of the claim if all the information required under section 8 of the  Hazardous Materials Information Review Regulations is included at the time of the submission.
Following registration, the claim undergoes an in depth review and a decision is made on:

  • whether the claim for exemption is valid;
  • whether the SDS (or label, in some cases) submitted with the claim complies with the Hazardous Products Act and the Hazardous Product Regulations ; and,
  • whether, in the case of an employer claim, other applicable federal or provincial/territorial occupational health and safety requirements apply.
