Security checks involve multiple organizations
Individuals who have gone through the immigration application process know how grueling it is.
Even if the applicant successfully brings their IELTS score to the highest possible, successfully secures a provincial nomination, or works long enough to qualify for immigration, there will still be 5% to 10% of newcomers who may run into this unfortunate situation: security checks.
The security check is a painful process. Although more than 99% of applicants pass this final phase, it takes about 6 to 12 months to complete. For some others, it may take one to two years. Comprehensive security screening is mainly conducted by the Canadian Security Intelligence Service (CSIS).
However, it also includes screening by Immigration, Refugees, and Citizenship Canada (IRCC), Canada Border Service Agency (CBSA), and Royal Canadian Mounted Police (RCMP).
