Supply Chain Ombudsman

CNL provides a confidential and unbiased route for Suppliers/Contractors to raise issues associated with either CNL procurement or working with CNL which will be managed in a fair, open and transparent manner. CNL always seeks improvements in its Supply Chain activities and welcomes constructive feedback. For issues and/or feedback, contact CNL’s Supplier and Relationship Development Manager Jack Springer.

Physical Work at CNL

Foreign Workers/Contractors/Suppliers

The Contractor/Supplier is responsible for obtaining necessary foreign worker permits prior to a non-Canadian working at a CNL site. A Government of Canada Website is used to navigate the process.  The user guide can be found at


As a nuclear facility, access to all CNL sites is controlled. Visitor passes are required to access the site for visits. These passes are arranged by Supply Chain personnel during pre-award and by the project execution team post-award. Security clearances of varying levels are required for personnel having access to CNL documents or performing work onsite. Forms are provided by CNL however individuals must undergo fingerprinting at their local police department and have background checks done prior to submitting the completed forms to CNL’s Personnel Security Services. Clearances must be in place before work can begin. The Supplier/Contractor is responsible for costs associated with security screening.

Due to changes introduced in the Standard on Security Screening which sets out the Government of Canada’s requirements for all levels of security screening, CNL is now required to conduct a financial inquiry (credit check) for all new and renewal security screenings. CNL’s Personnel Security Services will pull the applicant’s credit report as a “blind check”, which means CNL’s check will not be recorded on the applicant’s credit report, and CNL will not receive the applicant’s overall credit score from the reporting agency. Credit reports obtained as part of the security screening process are used only for that screening process and retained in the applicant’s confidential security file. Credit reports are not used or disclosed for any other purpose within or outside CNL.


All Contractors performing physical work on CNL Sites are required to undergo a half day Contractor Orientation course and a half day Radiation Protection course. Contractors performing work in higher radiological zones must undergo a five day training program. The specific nature of required training is provided in the procurement documents.

Radiation Protection

CNL Sites are broken into radiological zones 1 through 4. Some zones require that individuals wear a dosimeter to monitor exposure and the data is used to maintain records for annual and lifetime exposure. Prior to beginning work on a CNL Site it may be necessary for individuals to have a whole body count done to provide a baseline against which any future exposure is measured. The specifics of radiation protection measures for the work in question is contained within the procurement documents.

Health & Safety

The health and safety of all persons at CNL is of paramount importance. This includes employees, visitors, and contractors working at any of our sites. 

CNL is a federally regulated employer for purposes of workplace health and safety, and CNL adheres to the Canada Labour Code and associated Regulations. In general, Contractors working on our sites are regulated by the Act and Regulations of the province or territory in which the work is being carried out, unless they are a federally regulated sector (e.g. aviation or telecommunications). 

CNL categorizes contractors using a risk-based approach, based on the potential hazards related to the scope and nature of the work to be performed. CNL requires prospective contractors to participate in a screening and prequalification process, to ensure they have the capabilities and qualifications necessary to safely execute the work (e.g. programs, resources, training, and certifications). CNL has chosen ISN as our agent to perform this screening and prequalification.


ISNetworld ( is an online tool used to help streamline the process of collecting and maintaining safety, insurance, quality and regulatory information on contractors and suppliers. Contractors and Suppliers who submit documents to ISN need to be registered as members for which there is a yearly fee. Details of subscription fees can be found on the ISN portal. 

CNL currently uses ISN for verification of Contractor Safety Programs, whereby contractors shall demonstrate good standing. E.g. Shall be registered and meet the appropriate rating set out for relevant safety programs required. This is generally A, B or C. Contractors failing to meet such standards may require further verification to be undertaken, undertake specific corrective actions, or in some cases, may not be deemed appropriate to work on a CNL site. 

Membership is not required to submit a response to a CNL opportunity, however, CNL generally seeks that the contractor obtain membership and have the relevant programs validated by ISN upon notification of being a Preferred Proponent. 

CNL’s requirements for ISN include the following:

  • Company Profile 
  • Health, Safety and Environmental Questionnaire 
  • Safety Statistics Questionnaire 
  • HSSE Programs 
  • Certificates of Insurance 
  • Workers Compensation Rate Statement  


Many of the projects contracted by CNL require the supplier to be capable of demonstrating compliance to specific Nuclear Safety Related and or Quality Management System.  Such compliance will be confirmed by CNL prior to the award of any contract by a comprehensive review of the management system either by on site audit, document review or both.
