- Under section 21 of the Criminal Code, a person is a “party” to an offence not only by committing it, but by aiding or abetting someone else who commits it.
- In terms of guilt, there is no legal difference between being the person who actually committed the offence and being an aider or abettor — both are equally culpable.
- Aiding means assisting or helping the person who commits the offence; abetting means encouraging, instigating, or promoting the offence.
- Under section 22, a person who counsels someone else to commit an offence can be found guilty even if the offence was carried out differently than what was counselled.
- A person can even be liable under section 22(2) for a different offence than the one they counselled, if they knew or ought to have known it was likely to result.
- You can be charged as a party to an offence even if you were never physically present when it occurred.
The Short Answer
Yes — you can be charged with, and convicted of, a criminal offence you did not personally commit, if you aided, abetted, or counselled someone else who did. Sections 21 and 22 of the Criminal Code make aiders, abettors, and counsellors equally culpable as the person who actually carried out the offence.
Section 21: Parties to an Offence
Section 21(1) states that everyone is a party to an offence who:
- (a) actually commits it
- (b) does or omits to do anything for the purpose of aiding any person to commit it
- (c) abets any person in committing it
This means the law recognizes three distinct ways to become criminally responsible for the same offence — and all three are treated the same way legally.
What Counts as “Aiding”
To aid means to assist or help the person actually committing the offence. This can include providing tools, information, transportation, or any other assistance that helps the offence occur — even without directly participating in the criminal act itself.
What Counts as “Abetting”
To abet includes encouraging, instigating, promoting, or procuring the offence to be committed. This requires both an act (or omission) that encourages the principal offender, and the intent to abet, along with knowledge that the principal intended to commit the offence.
A person does not personally take part in a physical assault, but actively encourages and cheers on the person who does, knowing what is happening. This encouragement, combined with knowledge of the principal offender's intent, can be sufficient to establish liability as an abettor — even without ever throwing a punch.
Section 22: Counselling an Offence
Section 22 addresses a different form of party liability: counselling. Where a person counsels another person to be a party to an offence, and that other person actually goes on to be a party to it, the person who counselled is also a party to that offence — even if it was committed in a way different from what was actually counselled.
Under section 22(2), a person who counsels one offence is also a party to any other offence the counselled person commits as a result, provided the person doing the counselling knew or ought to have known that offence was a likely consequence of the counselling.
Equal Culpability: No “Lesser” Charge
A common misconception is that being an aider, abettor, or counsellor results in a lesser charge than being the actual perpetrator. In fact, Canadian law treats all parties to an offence as equally culpable — there is no built-in lesser charge simply because someone did not physically carry out the offence themselves.
Common Real-World Scenarios
- Acting as a lookout during the commission of an offence
- Providing a vehicle, knowing it will be used to commit or flee from an offence
- Encouraging or egging on a physical altercation without directly participating
- Planning an offence that someone else ultimately carries out
Possible Defences
- Arguing there was no genuine act of assistance or encouragement
- Arguing a lack of knowledge that the principal offender intended to commit the offence
- Arguing a lack of the specific intent required to aid, abet, or counsel
- Arguing mere presence at the scene, without more, does not establish party liability
Common Misconceptions
Myth: “I wasn't there, so I can't be charged.”
False. A person can be charged as an aider, abettor, or counsellor without being physically present when the offence itself occurred.
Myth: “If I just watched and didn't participate, I'm safe.”
Generally true on its own, but risky — mere presence without more is usually not enough, but presence combined with encouragement or assistance can cross the line into abetting.
Myth: “Being an accomplice gets you a lighter sentence automatically.”
False. Aiders, abettors, and counsellors are equally culpable in law — sentencing still depends on the specific facts and each person's actual role.

Frequently Asked Questions
Yes. Under section 21 of the Criminal Code, a person is a "party" to an offence — and can be charged and convicted of it — if they actually commit it, aid another person in committing it, or abet (encourage or assist) another person in committing it.
Aiding generally means doing something that helps or assists the person who actually commits the offence. Abetting generally means encouraging, instigating, or promoting the commission of the offence, even without directly assisting in its physical commission.
No. In terms of legal guilt, there is no difference between being an aider, an abettor, or the principal offender — all are equally culpable under Canadian law, and can be charged with, and convicted of, the same offence.
Counselling means encouraging, procuring, or inciting someone else to commit an offence. Under section 22, a person who counsels an offence can be found guilty as a party to it if the other person actually goes on to commit it — even if it was committed in a different way than what was counselled.
Yes, potentially. Under section 22(2), a person who counsels an offence is also a party to any other offence the counselled person commits as a consequence, provided the person doing the counselling knew or ought to have known that the other offence was a likely consequence of the counselling.
No. A person can be charged as an aider, abettor, or counsellor without ever being physically present when the offence itself was committed — for example, by providing tools, information, or encouragement in advance.
Generally, the Crown must prove both an act (doing something, or in some cases omitting to do something, that assists or encourages the offence) and the required intent — that the person intended to assist or encourage the principal offender, and knew the principal intended to commit the offence.
Generally, mere presence at the scene, without more, is not enough to establish party liability — there must be some act of assistance or encouragement, along with the required intent. However, presence combined with other conduct suggesting encouragement can be enough, depending on the specific facts.
Common defences include arguing there was no genuine act of assistance or encouragement, that the person did not know the principal intended to commit the offence, or that they lacked the required intent to assist or encourage it — the specific defence depends heavily on the facts of the case.
Yes, strongly recommended. Party liability charges carry the same potential consequences as being the principal offender, and building an effective defence requires carefully analyzing the specific acts, knowledge, and intent the Crown needs to prove.
