Applicants who are offered a position and accept the offer must successfully complete a CSIS Security Clearance as a condition of employment. This requirement ensures compliance with federal laws and Canadian Nuclear Safety Commission (CNSC) regulations governing nuclear operations.

Security clearances are mandatory for all roles whether in corporate functions or at nuclear, hydro, or fossil stations and apply to both employees and contractors. This process is essential to maintain safety, security, and regulatory compliance across all operations.

As part of the recruitment process, all selected candidates will be required to achieve and maintain an active security clearance. This involves a screening and verification of your employment, education, travel, criminal history, and eligibility to work in Canada.

Please be advised that all information collected is confidential and in accordance with privacy laws. The following is an overview of the security clearance process, and the requirements candidates will need to action
should they be selected as a successful candidate.

The security clearance consists of:
  • Criminal Record Name Check (CRNC) in Canada
  • CSIS Indices Check
  • Employment and Education Verification
The external agencies that handle the security checks are:
  • Criminal Record Name Check – Ontario Provincial Police (OPP)
  • CSIS Indices Check – Canadian Security Intelligence Service (CSIS)
  • Employment and Education Verification – Investigative Solutions Network Inc. (ISN)
A completed Security Clearance application consists of:
  • Online – Security Clearance Integrated Application (SCIA)
  • Hard copy – Printed forms from SCIA (signed, initialed, and dated)
  • Identification – 2 pieces of valid government issued identification specified on SCIA’s checklist
  • Documentation – All other supporting documentation specified on SCIA’s checklist (if applicable)
  • Verification – All copies of identification and supporting documentation must be verified and formally signed off by an authorized representative before submission. This step ensures authenticity and compliance with security clearance standards.
The only accepted forms of legal status documentation are as follows:
  • Canadian birth certificates
  • Canadian citizenship cards
  • Canadian permanent residence cards
  • A combination of your Canadian work permit AND non-Canadian birth certificate or driver’s license AND non-Canadian passport

All copies of identification/supporting documentation must be verified.

Verification/notarization is a measure used to prevent fraudulent use of forged identification/documentation.

Once a clearance is granted, it is valid for five years and transferrable to other utilities.

Depending on your personal history, the level of security check, and the volume of security clearance applications, the security clearance process can take between 10-15 weeks – in some cases, it may take longer.
