Maple News reports that Immigration, Refugees and Citizenship Canada (IRCC) employs DNA testing in select family immigration and citizenship applications when traditional documents such as birth certificates or adoption papers are missing or insufficient to prove biological relationships. DNA testing remains an optional tool; however, choosing not to participate when no alternative evidence exists may negatively affect a file’s outcome.
DNA testing is considered a last resort, used only after other verification methods such as interviews or procedural fairness letters have been exhausted. Applicants are never required to undergo testing, but IRCC officers must clearly explain the reasons for the request and outline the voluntary nature of the process.
In family sponsorship cases, DNA tests may be used to verify relationships such as parent-child, siblings, or other blood relatives. When confirming parentage, DNA samples are typically collected from the child, the mother, and where possible, the father. For sibling or extended relationships, parents or additional close relatives may also be tested to strengthen the case.
If the applicant resides in Canada, IRCC sends a DNA testing letter instructing them to select an accredited laboratory from the Standards Council of Canada (SCC). The test involves a simple, non-invasive saliva sample. Proof of identity, including government-issued photo ID and two passport photos, must be submitted along with signed consent. Overseas applicants may be scheduled for sample collection at Canadian visa or consular offices, sometimes under the observation of a migration officer or virtually through secure platforms like those managed by the International Organization for Migration (IOM).
All DNA samples must be securely handled from collection to testing. Labs must maintain a documented chain of custody and ensure tamper-proof shipping. Only results from SCC-accredited laboratories are accepted. These results must indicate a 99.8% or greater probability of a biological relationship to be considered valid by IRCC.
Once DNA test results are received, they are added to the applicant’s file and considered as part of the overall application. If results support the claimed relationship, they strengthen the application. If they do not confirm the relationship, IRCC may issue a procedural fairness letter before rendering a decision.
Applicants who decline testing will still have their case processed based on available documents. Declining DNA testing does not automatically mean non-compliance but may lead to refusal if alternate evidence is not compelling.
Internally, IRCC officers document the DNA request and result verification process in the Global Case Management System (GCMS). This ensures transparency, procedural fairness, and proper handling of sensitive information.
DNA testing plays a minor yet critical role in the family reunification and citizenship verification process. While not commonly requested, it serves as a scientifically robust means of proving relationships when documentation is missing or questioned. Canada’s approach emphasizes voluntary participation, applicant rights, and strict data handling protocols to ensure both fairness and privacy are upheld.
According to Maple News, understanding when and how DNA testing is used can better prepare aspiring immigrants and their families navigating the Canadian immigration system.
