Understanding Canada’s Security Screening Process for Immigration

This screening is an essential part of maintaining the integrity of Canada’s immigration system and is carried out by several federal agencies working together. As advanced security screenings become more common, we wanted to give you a high-level overview of security screenings and what it means for applicants. 

Key Takeaways 

• All applicants for temporary and permanent residence go through security screening. 

• Advanced screening happens when background details require deeper verification. 

• CSIS and CBSA handle these checks; IRCC cannot expedite them. 

• Patience and transparency are crucial — these screenings protect both the applicant and Canada’s security interests. 

Who Conducts the Screening 

Security screening in Canada is a joint effort between three main government agencies: Immigration, Refugees and Citizenship Canada (IRCC), the Canada Border Services Agency (CBSA), and the Canadian Security Intelligence Service (CSIS). Each plays an important role in ensuring that people entering or settling in Canada do not pose a security risk. 

• IRCC reviews all temporary and permanent residence applications and checks each applicant’s background for potential security concerns. If officers find information that needs a closer look, the file is referred for advanced security screening, a more detailed review of the applicant’s background. 

• CBSA, through its National Security Screening Division (NSSD), conducts these in-depth background checks to identify any links to organized crime, terrorism, or other threats to Canada’s safety. 

• CSIS supports CBSA’s efforts by assessing potential national security risks and sharing relevant intelligence to help inform the overall assessment. 

Together, these agencies ensure that all applicants are admissible to Canada and do not present a risk to national security. 

What the Security Screening Covers 

The goal of security screening is to identify whether an applicant could be inadmissible to Canada under the Immigration and Refugee Protection Act (IRPA). 

Officers look for any indication of: 

• Involvement in espionage, subversion, or terrorism 

• Membership in organizations that engage in such activities 

• Participation in war crimes, crimes against humanity, or organized criminal activity 

• Actions or associations that could threaten Canada’s security 

Most of these checks happen behind the scenes and involve verifying the information you’ve submitted, such as your personal history, employment, and travel records, against government and international databases. 

What Happens During Advanced Screenings 

When an application is referred for advanced screening, CSIS and CBSA conduct a deeper investigation.

This can involve: 

• Additional database searches. 

• Reviewing intelligence reports. 

• Verifying identity and background with foreign agencies. 

• Requesting interviews or extra documentation. 

This process is confidential and beyond IRCC’s direct control, which means applicants, and even case officers, may not be informed of its details or duration. 

How Long Advanced Screening Takes 

Routine screenings are generally finalized within the standard processing timeframe for the specific application type. 

However, when an application is referred for advanced screening, the process can take several additional months, and in some cases, up to a year or longer, depending on the complexity of the applicant’s background and the level of coordination required among government agencies. 

Because this stage of the process is confidential, IRCC does not provide detailed updates while it is underway. Applicants may, however, request GCMS notes to obtain general information about the status of their file. That said, due to the confidential nature of advanced security screening, certain details or sections of those notes may be redacted and not visible to the applicant. 

With more applications being referred for advanced screening, there is increasing pressure on the system to improve transparency around timelines and next steps. Many observers and applicants alike have called for clearer communication to help manage expectations during extended security reviews. 

Tips for Applicants 

The security screening process is largely out of an applicant’s control, but there are still a few things individuals can do to help prevent avoidable delays or confusion along the way. 

To help mitigate issues and keep your application on track: 

• Ensure your background information is accurate and complete — include all addresses, jobs, and travel history. 

• Provide supporting documents proactively, especially if your background includes military, police, or government service. 

• Avoid leaving out details, even unintentionally, as missing information can raise red flags or trigger further review. 

• Stay patient and informed — advanced screening is not automatically a negative finding; it simply means that additional verification is needed before a decision can be made.
