Under the Immigration and Refugee Protection Act (IRPA), a person may be found inadmissible to Canada on the grounds of security for any of the following:

• engaging in an act of espionage that is against Canada or that is contrary to Canada’s interests;
• engaging in or instigating the subversion by force of any government;
• engaging in an act of subversion against a democratic government, institution or process as they are understood in Canada;
• engaging in terrorism;
• being a danger to the security of Canada;
• engaging in acts of violence that would or might endanger the lives or safety of persons in Canada; or
• being a member of an organization that there are reasonable grounds to believe engages, has engaged or will engage in espionage, subversion, or terrorism.

The Canada Border Service Agency (CBSA) must have “reasonable grounds to believe” someone is inadmissible on national security grounds, which could be based on expert opinions, police or intelligence reports, media articles, testimonies, and other factors. A person could be inadmissible if suspected of planning to commit an act. These allegations are extremely serious and you should seek professional assistance to address the situation.
