If your organization has an occupational health and safety management system (OHSMS), you can apply to have it accredited by the Ministry of Labour, Training and Skills Development’s Chief Prevention Officer (CPO).

Under the Occupational Health and Safety Act, an OHSMS is defined as “a coordinated system of procedures, processes and other measures that is designed to be implemented by employers in order to promote continuous improvement in occupational health and safety.”

If you use an accredited health and safety management system you may apply to the CPO for employer recognition and could be eligible to receive a rebate on premiums from the Workplace Safety and Insurance Board (WSIB). Learn more about the employer recognition criteria established by the CPO.

This guideline was developed to help you complete the OHSMS accreditation application form.

Who is eligible

To receive CPO accreditation, your OHSMS must meet all the requirements contained in the CPO OHSMS accreditation standard, and be either an:

  • industry-based management system standard developed by a technical advisory
  • organization-specific management system that is successfully implemented and active in a workplace

Section A: Application information

1. Applicant information

This section requires you to provide:

Canada Revenue Agency Registered Business Number

The business number (BN) is a unique number, assigned to a business by the Canada Revenue Agency (CRA), that simplifies and streamlines the way businesses deal with federal, provincial and municipal governments. Your business number can be found in your 15-digit CRA account number (see below for an example). Please use your 9-digit BN or your 15-digit CRA account number in your application.

    • Reference number/account: 0001

Ontario uses and collects the business number when interacting with businesses in the province.

If you are applying with an organization-specific OHSMS, the designated contact must also:

  • be an employee of the organization

  • have knowledge of OHSMS implementation, monitoring and its continued improvement

  • the industry for which the standard was developed
  • the North American Industry Classification System (NAICS) codes within the industry
  • the number of workplaces that use the standard

The designated contact and alternate contact are both required to read, understand and agree before signing this section.

Section B: Attestation


Attestations are used as part of the accreditation application process to confirm, verify and provide evidence that the criteria have been met.

If you do not complete this section, we cannot accept your application and the review process will be delayed.


Sign and date the form, and check the box affirming you have signing authority for your organization. If this is not affirmed, the application will not be processed.

Section C: OHSMS assessment and evidence

You must show how your OHSMS meets the requirements of the standard by including:

  • precise references to where requirements can be found in your OHSMS
  • a description of how each requirement is met

Please do not submit your complete OHSMS. Include enough information for each requirement to show that it is met within your OHSMS. You may do this by providing:

  • an outline of how the requirement is met
  • direct language from the OHSMS
  • an explanation of the concept that clearly shows how it meets the requirement

If you have developed an OHSMS standard, please submit a copy with your application.

How to fill out the chart in the application form

The first two columns in the application form provide reference information about requirements in the CPO accreditation standard that you need to meet.

The last three columns provide space for you to input information on how you meet each requirement.

Each requirement will appear in a separate row.

Column 1: Section number in CPO standard

Identifies the specific clause number in the CPO accreditation standard. This is pre-populated for your reference. You are not required to do anything in this column.

Column 2: Requirement

Provides the language of the requirement taken directly from the CPO accreditation standard. This is pre-populated for your reference. You are not required to do anything in this column.

Column 3: Document control reference number

Element 5.2.9 of the CPO accreditation standard requires document controls, such as version controls, page numbers, clause numbers and/or unique identifiers. 

If you use an individual OHSMS:

  • provide specific references in your OHSMS that address the requirement in Column 2

If you use an industry-based standard:

  • provide the specific clause number in your industry-based standard that addresses the requirement in Column 2
Column 4: Title of document

If you use an individual OHSMS:

  • provide the title or name of the document that contains the references in Column 3
  • provide a title for each requirement so it is clear which specific document contains the requirement, even if the title or name is repeated in multiple rows

If you use an industry-based standard:

  • all requirements should be contained within the standard itself, however sometimes a standard may reference complementary material as well.
  • provide the title of the document that contains the clause numbers in Column 3
Column 5: Brief description of how the OHSMS meets the requirements

Briefly explain how your individual OHSMS or the industry-based standard you use meets the specific requirement in Column 2

If you use an individual OHSMS:

  • you do not need to submit your entire OHSMS
  • you must include a sufficient explanation to determine whether the intent of the requirement has been met, or we may determine that the requirement has not been met
  • describe how each requirement relates to the others, if applicable

If you use an industry-based standard:

  • submit the entire standard with this application
