Plain-Language Summary

Terrorism: What It Means Under Canadian Law

Terrorism offences involve acts done for a political, religious, or ideological purpose, where the law treats the conduct as terrorist activity. The Crown must prove the required purpose and the person’s role in the offence charged. Penalties range from 5 years to life in prison, depending on the offence. There is no minimum sentence.

Terrorism: Like many countries around the world, Canada moved quickly to update its laws to deal with the threat of terrorismAn offence aimed at intimidating the public following the 9/11 attacks in 2001. Canada amended the Criminal CodeA federal act codifying most criminal offences in Canada, the Official Secrets Act, the Canada Evidence Act, the Proceeds of Crime Act and a number of other acts, passing the Anti-terrorism ActA federal law that added terrorism-related offences, powers, and procedures after 2001. (ATA). The Code defines terrorism as an effort committed “in whole or in part for a political, religious or ideological purpose, objective or cause” with the intention of intimidating the public. If you commit an act of terrorism or knowingly instruct, directly or indirectly, any person to carry out a terrorist activity you could be imprisoned for life.

What Is Terrorism?

According to the Department of Justice (DoJ) "acts of terrorism threaten Canada's political institutions, the stability of the economy and the general welfare of the nation."

The Anti-terrorism Act was enacted in December 2001 with four objectives:

  • to prevent terrorists from getting into Canada and protect Canadians from terrorist acts:
  • to activate tools to identify, prosecute, convict and punish terrorists;
  • to keep the Canada-U.S. border secure and a contributor to economic security; and
  • to work with the international community to bring terrorists to justice and address the root causes of violence.

Prior to the introduction of the ATA, Canada did not have a law that specifically dealt with terrorism.

Terrorist activity is seen as being among the most serious crimes in Canadian law and includes an act that:

  • causes death or serious bodily harm to a person by the use of violence;
  • endangers a person's life;
  • causes a serious risk to the health or safety of the public or any segment of the public,
  • causes substantial property damage, whether to public or private property; and
  • causes serious interference with or serious disruption of an essential service, facility or system, whether public or private.

The ATA reflects a commitment to the safety of all Canadians, states the DoJ, and strengthens "Canada's ability to meet its international obligations, while respecting Canadian values and the rights enshrined in the Canadian Charter of Rights and Freedoms."

Terrorism offences are covered under PART II.1 of Offences Against Public Order and include a number of different crimes.

Financing of Terrorism

Financing terrorism will have you guilty of an indictable offence and liable to imprisonment for a term of not more than 10 years if you, directly or indirectly, wilfully and without lawful justification or excuse, provide or collect property intending to be used or knowing that it will be used to carry out an act of terrorism under s.83.02. You also face the same prison sentence if you directly or indirectly, collect property, provide or invite person to provide, or make available property or financial or other related services that will be used in a terrorist activity under s.83.03. If you use property for the purpose of facilitating or carrying out a terrorist activity, or possesses property intending that it be used for terrorist activity you face up to 10 years in prison under s.83.04.

Participation in the Activity of a Terrorist Group

Under s.83.18(1), if you knowingly participate in or contribute to, directly or indirectly, any activity of a terrorist group for the purpose of enhancing the ability of any terrorist group to facilitate or carry out a terrorist activity, you are guilty of an indictable offence and liable to imprisonment for a term of not more than 10 years. This charge can be laid even if no terrorist activity takes place, even if your participation did not actually enhance the group's ability to do so, and even if you did not know the specific nature of any terrorist activity the group might carry out. You do not have to have planned or intended the terrorist act itself.

Facilitation of Terrorist Activity

You can face up to 14 years in jail if you knowingly facilitate a terrorist activity under s.83.19(1). You do not have to have knowledge of the specific activity and it does not matter if the terrorist act was carried out.

Leaving Canada to Facilitate Terrorist Activity

Section 83.191 states that if you leave or attempt to leave Canada for the purpose of committing an act or omission outside Canada that would be an offence under subsection 83.19(1) you can be jailed for up to 14 years.

Commission of an Offence for a Terrorist Group

You can be jailed for life if you commit an indictable offence for the benefit of, at the direction of or in association with a terrorist group under s.83.2 of the Code.

Leaving Canada to Commit an Offence for a Terrorist Group

According to s.83.201, leaving or attempting to leave Canada for the purpose of committing an act or omission outside Canada that would be an indictable offence for the benefit of, at the direction of or in association with a terrorist group is liable to imprisonment for a term of not more than 14 years.

Instructing to Carry out an Activity for a Terrorist Group

If you knowingly instruct, directly or indirectly, any person to carry out any activity for the benefit of, at the direction of or in association with a terrorist group to facilitate or carry out a terrorist activity, you could be prosecuted and will face a lifetime prison sentence under s.83.21(1). The act of terrorism does not have to be carried out for you to be charged. 

Instructing to Carry out a Terrorist Activity

Section 83.22(1) states that if knowingly instruct, directly or indirectly, any person to carry out a terrorist activity you are guilty of an indictable offence and liable to imprisonment for life. Again, the terrorist act does not have to be carried out.

Counselling the Commission of a Terrorism Offence

If you counsel another person to commit a terrorism offence without identifying a specific terrorism offence you can be found guilty of an indictable offence and you are liable to imprisonment for a term of not more than five years under s.83.221(1) of the Criminal Code.

Concealing Person who Carried out Terrorist Activity

If you knowingly harbour or conceal someone who has carried out a terrorist activity or for the purpose of enabling that person to facilitate or carry out any terrorist activity, you can be found guilty of an indictable offence and jailed for up to 14 years under s.83.23(1).

Concealing Person Who is Likely to Carry Out Terrorist Activity

Under s.83.23(2) you face up to 10 years in jail if you knowingly harbour or conceal another person you know to be a person who is likely to carry out a terrorist activity.

Hoax - Terrorist Activity

Under s.83.231(1) you face five years in prison if you commit an act that is likely to cause a reasonable apprehension that terrorist activity is occurring or will occur, without believing that it will happen.

It is important to note that any prison sentence for terrorism will be served consecutively to any other time in custody you receive for any "offence arising out of the same event or series of events." The exception would be if you commit a crime that results in a lifetime prison term.

A conviction will also result in collection of your DNA, which will be held in the DNA Data Bank.

What is Needed to Convict

To win a conviction for an act of terrorism, the Crown prosecutorA lawyer who conducts a criminal prosecution on behalf of the public. must establish the crime constitutes terrorist activity and you knowingly participated. Along with proving your guilt beyond a reasonable doubtThe standard that must be exceeded to find someone guilty, the court must be satisfied that the act itself falls within the legal definition of "terrorist activity" under s.83.01 of the Criminal Code. That definition requires, among other things, that the act was committed in whole or in part for a political, religious or ideological purpose, objective or cause. This is built into what makes an act "terrorist activity" in law, rather than being a separate question about your personal beliefs or motivation. In practice, depending on the specific offence charged, the Crown may also need to prove you acted with a particular purpose, such as enhancing the ability of a terrorist group to carry out a terrorist activity.

Treated as an Indictable Offence

Most terrorism offences under Part II.1 of the Criminal Code are indictable offenceA more serious type of Canadian criminal offence.s. Indictable offences are reserved for serious crimes and carry the most significant prison sentences upon conviction. One exception on this page is the terrorism hoax offence under s.83.231: for the basic hoax offence and for a hoax that causes bodily harm, the Crown may choose to proceed either by indictment or by summary convictionUsed for lesser offences. A hoax that causes death is indictable only.

Terrorism offences in the Criminal Code

Terrorism is a category of offences in Part II.1 of the Criminal Code, built on the definitions of “terrorist activity” and “terrorist group” in s. 83.01. Part II.1 contains multiple distinct offences — participating, facilitating, financing, instructing, counselling, and harbouring — and each has its own penalty. Terrorism offences can carry serious penalties, from fixed maximum terms to life imprisonment depending on the section.

Where the specific offences are covered

Each terrorism offence has its own page with its penalty details: Participation in Activity of a Terrorist Group, Facilitating Terrorist Activity, and Financing of Terrorism.

Sentencing note

Some terrorism offences also have special sentencing rules.

Possible Defences and Legal Issues

This page covers more than one section. Possible defences and legal issues are set out by section below.

Terrorism — Financing Offences (ss.83.02, 83.03(1)-(2))

The financing offences in ss.83.02 and 83.03(1)-(2) only apply where the person acts "wilfully and without lawful justification or excuse". If there is evidence capable of raising a lawful justification or excuse, the Crown must prove beyond a reasonable doubt that the person acted without one. Other terrorism offences on this page, such as participation, facilitation, and instructing, do not use this wording — see the dedicated Financing of Terrorism page for the full detail, including two further exceptions specific to s.83.03.

The Crown still has to prove the other parts of these offences too, including that property, money, or services were provided, collected, or made available for a terrorist purpose.

Terrorism — s.83.03(3)-(4) (Exceptions to the Financing Offences)

Section 83.03 carries two further exceptions that do not apply to the other offences on this page. Subsection (3) says: "Subsection (2) does not apply to a person who carries out any of the acts referred to in that subsection under and in accordance with an authorization granted under section 83.032". Subsection (4) — added in 2023 — says subsections (1) and (2) "do not apply to a person who carries out any of the acts referred to in those subsections for the sole purpose of carrying out humanitarian assistance activities conducted under the auspices of impartial humanitarian organizations in accordance with international law while using reasonable efforts to minimize any benefit to terrorist groups".

Both grounds are narrow and fact-specific. The Crown still has to prove the other parts of the offence.

Terrorism — Other Part II.1 Offences on This Page

The remaining offences described on this page — using or possessing property for terrorist purposes (s.83.04), participating in the activity of a terrorist group (s.83.18), facilitating terrorist activity (s.83.19), committing an offence for a terrorist group (s.83.2), instructing an activity or an offence for a terrorist group (s.83.21, s.83.22), counselling a terrorism offence (s.83.221), and concealing a person connected to terrorist activity (s.83.23) — do not list a special defence in the Criminal Code. The Crown still has to prove the parts of whichever offence is charged, including the specific knowledge and purpose that section requires.

Possible issues may still depend on the facts, the evidence, and whether the Crown can prove each part of the offence, and whether the conduct meets the Criminal Code definition of terrorist activity discussed above. This is general legal information, not legal advice.

Application / Scope

Limits on “terrorist activity” — s. 83.01

Every offence on this page depends on the definition of “terrorist activity” (and, for some offences, “terrorist group”) in section 83.01, and that definition has built-in limits that apply across Part II.1. It "does not include an act or omission that is committed during an armed conflict and that, at the time and in the place of its commission, is in accordance with customary international law or conventional international law applicable to the conflict", or certain activities of a state's armed forces carried out under other rules of international law. For conduct said to disrupt an essential service, the definition also excludes anything happening "other than as a result of advocacy, protest, dissent or stoppage of work that is not intended to result in the conduct or harm referred to in any of clauses (A) to (C)" — in plain terms, lawful protest, advocacy, dissent, or a work stoppage is not terrorist activity unless it is meant to cause death, serious bodily harm, danger to life, or a serious risk to public health or safety. Section 83.01(1.1) adds that "the expression of a political, religious or ideological thought, belief or opinion does not come within paragraph (b) of the definition terrorist activity in subsection (1) unless it constitutes an act or omission that satisfies the criteria of that paragraph".

If the conduct behind any terrorism charge on this page falls within one of these limits, it does not meet the legal definition that the offence depends on. The Crown still has to prove every other part of whichever offence is charged.

Common Legal Terms

Terms marked with a dotted underline in the article above are defined here and available in the full site glossary.

Crown prosecutor
Glossary entry →

A Crown prosecutor is a lawyer who conducts a criminal prosecution on behalf of the public. The Crown’s role is to present the case fairly, exercise independent judgment, and act in the public interest. The Crown’s role is not simply to obtain a conviction.

Indictable offence
Glossary entry →

An indictable offence is generally a more serious type of Canadian criminal offence. Some indictable matters have higher maximum penalties and may involve different court procedures, including election about the mode of trial in some cases.

Reasonable doubt
Glossary entry →

The Supreme Court of Canada has said that reasonable doubt “falls much closer to absolute certainty than to proof on a balance of probabilities” and “that something less than absolute certainty is required, and that something more than probable guilt is required."

Summary conviction
Glossary entry →

Summary convictions are used for lesser offences with penalties, fines and short jail time. They reflect the majority of offences as defined in the Code.
