What is security inadmissibility and how does it affect immigration to Canada?

Security inadmissibility under federal immigration law can bar a person from entering Canada or obtaining permanent residence based on concerns about national security, membership in terrorist organizations, espionage, or engaging in acts of violence or crimes against humanity. Assessments are made by IRCC and, in more serious cases, involve the Canadian Security Intelligence Service (CSIS) and CBSA. This is a federal determination — Ontario courts have no role.

Security background checks are part of all immigration applications. Most applicants pass without issue, but those who have lived in certain countries, held certain positions, or have certain associations may trigger additional scrutiny. The process for security screening is not fully transparent to the applicant; CSIS recommendations are protected. If a security concern is identified, IRCC will typically issue a procedural fairness letter before making a finding of inadmissibility.

Findings of security inadmissibility are very difficult to overcome and have serious long-term consequences. Unlike criminal inadmissibility, there is no simple rehabilitation pathway for most security grounds. If you have received a notice suggesting a security inadmissibility concern, or if you are aware of past associations or activities that might raise concerns, legal advice from a lawyer experienced in this area is essential before you apply for any status in Canada.
