In Canada, concealing terrorist activity Canada—specifically, concealing a person who is likely to carry out a terrorist activity—is a distinct and serious crime under the Criminal Code. Classified as an indictable offence and tracked under UCR Code 3727, this charge targets anyone who knowingly hides, shelters, or otherwise conceals a person they know is likely to engage in terrorism, for the purpose of helping that person plan, facilitate, or commit a terrorist act. Even if no attack ultimately occurs, the act of harbouring or concealing such a person can lead to significant prison time and a permanent criminal record.
The Legal Definition
“Every person who knowingly harbours or conceals another person whom they know to be a person who is likely to carry out a terrorist activity, for the purpose of enabling that other person to facilitate or carry out any terrorist activity, is guilty of an indictable offence and liable to imprisonment for a term of not more than 10 years.”
This definition comes from section 83.23(2) of the Criminal Code of Canada. In plain English, the law makes it a crime to knowingly hide or shelter a person when you both (1) know that they are likely to carry out a terrorist activity, and (2) are doing it in order to help them either plan or carry out that terrorist activity.
The wording of section 83.23(2) creates several specific elements the Crown must prove beyond a reasonable doubt. First, the accused must have harboured or concealed another person—this can include providing a safe house, hiding them from police, or otherwise helping them avoid detection. Second, the accused must have known that this other person was “likely to carry out a terrorist activity,” which imports a high level of subjective awareness, not just suspicion or vague concern. Third, the Crown must show that the accused acted for the purpose of enabling that person to facilitate or carry out a terrorist activity. In other words, the concealment must be directly tied to supporting terrorism, not for some unrelated motive.
Penalties & Sentencing Framework
- Offence type: Indictable offence (no summary option).
- Mandatory minimum sentence: None.
- Maximum sentence: Imprisonment for a term of not more than 10 years.
Because concealing a person likely to carry out a terrorist activity is strictly an indictable offence, it is treated as one of the more serious categories of criminal conduct in Canada. There is no option for the Crown to proceed summarily, and the matter will follow the more formal indictable process, which can include a preliminary inquiry (where available), trial in a higher court, and the full range of criminal procedure protections and obligations that apply to indictable crimes.
Although there is no mandatory minimum penalty written into section 83.23(2), the courts treat terrorism-related conduct with particular gravity. Sentencing judges must consider the broader anti-terrorism framework in the Criminal Code, which recognizes that even preparatory or supportive acts can seriously endanger public safety and national security. A person convicted under this section can face a sentence anywhere from a non-custodial disposition (in very rare and exceptional cases) up to the statutory maximum of 10 years’ imprisonment. The actual sentence will depend on factors such as the nature and immediacy of the planned terrorist activity, the level of support provided, the offender’s role, and their personal circumstances.
Unlike some other terrorism offences that may carry extremely long maximum penalties or mandatory minimums, this particular provision focuses on harbouring or concealing a likely terrorist. Courts will examine how deliberate and sustained the concealment was, whether the concealment significantly impeded law enforcement, and whether the planned terrorist activity was close to being carried out. Aggravating factors can include any direct link between the concealment and the risk or harm posed to the public, involvement with organized terrorist groups, or acting for ideological, political, or religious extremism. Mitigating factors can include early guilty pleas, cooperation with authorities, limited involvement, or evidence of rehabilitation.
Common Defenses
-
Lack of knowledge that the person was likely to carry out terrorist activity
Section 83.23(2) explicitly requires that the accused “know” that the person they concealed was likely to carry out a terrorist activity. This is a subjective mental element: the Crown must prove that the accused actually knew, not just that a reasonable person might have suspected something. A common defense is to argue that the accused did not have this level of knowledge. For example, the accused may have believed the person was fleeing unrelated criminal charges, immigration issues, or personal problems, without any understanding that terrorism was involved. Evidence such as text messages, conversations, and the accused’s background can be used to show that they did not truly grasp the nature of the other person’s intentions. If the Crown cannot establish this knowledge beyond a reasonable doubt, the offence cannot be made out. -
Absence of purpose to enable facilitation or carrying out of terrorist activity
Another critical element is the requirement that the accused acted “for the purpose of” enabling the other person to facilitate or carry out a terrorist activity. It is not enough that the accused harboured or concealed someone who turned out to be a likely terrorist; the concealment must be motivated by an intention to assist or further the terrorist goal. A defense can therefore focus on the accused’s purpose or motive. For instance, an accused might argue that they provided shelter purely out of humanitarian concern, fear for the person’s safety from non-state actors, or family loyalty, without intending to assist any terrorist plan. While morally complex, the legal question is whether they meant to help the terrorist activity itself. If the accused’s intent was unrelated to enabling terrorism—despite their knowledge of possible wrongdoing—the specific mental element required by section 83.23(2) may not be met. -
Charter rights violations (e.g., section 7 or 11 of the Canadian Charter of Rights and Freedoms)
Defences may also arise from alleged breaches of the Canadian Charter of Rights and Freedoms. For example, under section 7 (life, liberty, and security of the person) and section 11 (legal rights of persons charged with an offence), an accused can challenge how the law was applied or how the investigation and prosecution were carried out. If police obtained evidence through unlawful searches, detentions, or interrogations, the defence may seek to exclude that evidence under section 24(2) of the Charter. In some cases, counsel may argue that the wording or application of section 83.23(2) is overbroad or vague in a way that unjustifiably infringes section 7 rights, though courts generally give Parliament leeway in crafting anti-terrorism laws. Where a Charter violation is established, the remedy could be exclusion of key evidence or, in rare cases, a declaration that the law is unconstitutional as applied, both of which could significantly weaken or terminate the prosecution.
Real-World Example
Imagine a scenario where a person allows a close friend to live in their basement for several weeks. The friend admits they are gathering materials and planning a bombing of a public building as part of an extremist cause. Knowing this, the homeowner continues to provide shelter, internet access, and a discreet place to store equipment, while also lying to police and neighbours about the friend’s whereabouts. Under section 83.23(2), the homeowner could be charged with concealing a person who is likely to carry out a terrorist activity. Law enforcement would treat the homeowner as an active supporter of terrorism, not merely a passive bystander. The court would assess whether the homeowner truly believed the friend was likely to carry out a terrorist act and whether their purpose in concealing them was to enable that activity. If the evidence showed clear knowledge and an intent to help, the homeowner could face a significant prison sentence even if police intervened before the bombing occurred. This illustrates how Canadian law criminalizes not only direct participation in terrorist activity but also the act of hiding and protecting those planning it—central to the broader regime surrounding concealing terrorist activity Canada.
Record Suspensions (Pardons)
A conviction under section 83.23(2) creates a permanent criminal record for an indictable offence. Under Canadian law, a person convicted of this offence is generally eligible to apply for a record suspension (pardon) after a waiting period, assuming they meet all criteria set by the Parole Board of Canada. For indictable offences, this period is typically 10 years following the completion of the entire sentence, including any term of imprisonment, probation, and the payment of fines or surcharges. The individual must remain crime-free during this time and demonstrate good conduct. While eligibility exists, terrorism-related convictions are scrutinized very closely. The Board will consider the seriousness of the offence, the risk to public safety, and any ongoing concerns about extremism or association with terrorist groups. A record suspension, if granted, does not erase the conviction but separates it from publicly visible criminal records, helping with employment and travel, subject to exceptions in national security contexts.
