Common Questions and Answers

  1. the chemical identity of any ingredient in a controlled product;
  2. the concentration of any ingredient in a controlled product;
  3. the name of any toxicological study that identifies any ingredient of a controlled product.
  1. the same three information types as the supplier;
  2. the chemical, common, generic, trade or brand name of a controlled product;
  3. information that could be used to identify a supplier of a controlled product.
  1. determine whether you are considered a supplier or employer under the HPA, CLC or OSH acts;
  2. determine if you have controlled product(s) as defined by the CPR;
  3. classify your products and prepare the required MSDS/labels;
  4. determine if the information on one or more of the hazardous ingredients is considered trade-secret or proprietary (chemical identity, concentration, supplier); then
  5. provide all of the mandatory information required under section 8 of the HMIRR. HMIRC's Claim for Exemption Form is designed to facilitate the submission of this information. If you require assistance, please contact our offices at 613-993-4331 and ask to speak to a Client Services Officer.
  1. $1,800 for each original claim up to 15 original claims in one submission (1–15);
  2. $400 for each of the next 10 original claims in one submission (16–25);
  3. $200 for each additional claim submitted above 25 original claims in one submission.
  1. $1,440 for each refiled claim up to 15 refiled claims in one submission (1–15);
  2. $320 for each of the next 10 refiled claims in one submission (16–25);
  3. $160 for each refiled claim submitted above 25 refiled claims in one submission.
  • Section 9 of the HMIRR specifically directs claimants to send in their claims by registered mail or have them delivered in person. HMIRC encourages the use of couriers for the delivery of claims.
  • CBI and product formulation data should always be placed in sealed envelopes which have been appropriately labelled.
  • Regular mail, electronic mail (e-mail) or facsimile are NOT appropriate means of transmitting CBI to HMIRC. However, Section 9 of the HMIRR has recently been amended to provide a legal framework for electronic transmission of claims in the future, providing HMIRC has the necessary facilities for accepting the secure transmission of claims by that means. HMIRC is conducting research into options for implementing the necessary facilities to allow secure electronic transmission.
  • The relevant MSDS must accompany each product that you are claiming.
  • The controlled product identifiers on the MSDSs must match exactly the product identifiers listed in Parts III and VII of the Claim for Exemption Form .
  • The envelope containing the claimed CBI MUST be sealed to ensure confidentiality.
  • CBI shown on Part VII of the claim should match with the products listed in Part III of the Claim for Exemption Form .
  • CAS numbers or chemical names of the CBI ingredients should NOT appear on the MSDS supplied with the claim but be provided on Part VII of the Claim for Exemption Form .
  • The GCI of the claimed CBI ingredients should be listed in Part VII of the form as well as on the MSDS. These generic chemical identities must match.
  • It is advisable to provide data on the product's total formulation at the time of your claim filing. The screening officer will request the total formulation at a later date, if it is not supplied at this time. This includes the precise chemical identity, CAS registry number and percent concentration of each “non-hazardous” ingredient present in the controlled product at a percent concentration of 0.1 or greater, which has not been disclosed on the MSDS accompanying the claim being filed. This information assists the screening officer in the MSDS review, which entails a verification that all hazardous ingredients in the controlled product have been disclosed on the MSDS. When submitting this data, every effort should be made to ensure that the percent concentrations of the hazardous plus “non-hazardous” ingredients account for virtually the total formulation of the product. Product formulation data should be placed in the same sealed envelope as the claimed CBI.
  • “Proprietary Secret” is not an acceptable means of complying with section 16 of the HPA—the generic chemical identity must be shown.
  • All claimed CBI ingredients must be identified individually by their GCI (i.e. one generic name followed by “and additives” is not acceptable). Note that it is acceptable to use the same GCI for more than one CBI ingredient if appropriate. Should you have two or more CBI ingredients with the same GCI, you have a choice of options:
    • You may either number the GCI, such as alkylamine 1, alkylamine 2, etc., if one or more of the ingredients with the same GCI are referred to on the MSDS in the discussion of hazards or toxicity; or
    • if there is no reference on the MSDS to any particular ingredient which shares the same GCI, then you may pluralize the GCI; for example, alkylamines (3), indicating that there are three alkylamines in the product.
