To begin a career with Defence Construction Canada (DCC), you must be a Canadian Citizen or a permanent resident of Canada. As a condition of employment with DCC, a minimum reliability security status clearance is required and some roles may require secret security status clearance.

DCC is responsible for the Personnel Security Clearance process. Typically to be eligible for a "Reliability" clearance, you must have five years of verifiable background information and to be eligible for a "Secret" clearance, you must have 10 years of verifiable background information. The process usually involves reference inquiries, verification of qualifications, criminal records checks, and credit checks (as required) and may require fingerprints. For more information about obtaining a security clearance, please review the Standard on Security Screening.

The appropriate security clearance is a condition of employment and it is the candidate’s or employee’s responsibility to ensure, they are able to obtain and maintain their required security level clearance to begin or continue their employment with DCC. Failure to obtain or maintain, the appropriate level of security clearance means either the candidate or employee will not receive a job offer, the conditional offer will be rendered null and void or their employment will be terminated with cause. A thorough security clearance process will be applied to all candidates or employees considered for an appointment; this process includes inquiries, verifications and assessments regarding matters such as, but not limited to:

criminal record checks

reference checks

previous employment

open source checks

credit/financial status

While we welcome applications to our roles who are not Canadian citizens who are eligible to work in Canada and have at least 5 years of verifiable background information, selection will depend on the specific role’s requirements.
