Key Takeaway
Assaulting a peace officer is charged under section 270 of the Criminal Code of Canada and carries a maximum penalty of five years imprisonment. More serious versions of the offence, assault with a weapon or causing bodily harm to a peace officer (section 270.01, maximum 10 years) and aggravated assault of a peace officer (section 270.02, maximum 14 years), carry significantly harsher penalties. There is no mandatory minimum sentence, but courts must prioritize deterrence and denunciation. The Crown must prove the accused committed an assault, that the victim was a peace officer acting in the lawful execution of their duty, and that the accused knew this. Common defences include challenging the lawfulness of the officer’s conduct, self-defence, lack of intent, and Charter violations.
What Is Considered Assault on a Peace Officer?
Under section 270(1) of the Criminal Code, you commit this offence if you assault a public officer or peace officer who is engaged in the execution of their duty, assault someone with intent to resist or prevent a lawful arrest, or assault a person engaged in the lawful execution of a legal process or seizure.
The definition of “assault” follows section 265 of the Criminal Code: intentionally applying force without consent, attempting or threatening to apply force, or accosting someone while carrying a weapon. Even minor physical contact, such as pushing an officer’s hand away during an arrest, can result in a charge.
A “peace officer” is not limited to police. Section 2 of the Criminal Code defines the term broadly to include correctional officers, sheriffs, justices of the peace, customs officers, conservation officers, military police, and others. That said, the vast majority of charges under section 270 involve police officers.
Penalties: The Three Levels of Severity
The Criminal Code creates three tiers of offences for assaults against peace officers:
- Section 270, Assault peace officer: A hybrid offence. Maximum five years imprisonment by indictment or two years less a day on summary conviction.
- Section 270.01, Assault peace officer with a weapon or causing bodily harm: A hybrid offence. Maximum 10 years imprisonment by indictment.
- Section 270.02, Aggravated assault of peace officer: A straight indictable offence. Maximum 14 years imprisonment. Applies where the officer is wounded, maimed, disfigured, or their life is endangered.
There is no mandatory minimum sentence for any of these offences. However, section 718.02 of the Criminal Code requires the court to give primary consideration to deterrence and denunciation when sentencing for offences against peace officers. Section 270.03 further provides that any jail sentence for assaulting a peace officer must be served consecutively to sentences for other offences arising from the same incident. In practice, this means judges treat these charges significantly more seriously than comparable assaults on civilians.
What Must the Crown Prove?
To secure a conviction, the Crown Attorney must prove each of the following beyond a reasonable doubt:
- The accused committed an assault as defined under section 265.
- The victim was a peace officer (or public officer, or person acting in aid of such an officer).
- The peace officer was engaged in the lawful execution of their duty at the time.
- The accused knew, or ought to have known, that the victim was a peace officer.
The third element is often the most contested. If the officer was not acting lawfully, for example, if the arrest was unlawful or the officer used excessive force, the charge may fail on this element alone.
Common Defences
Our criminal defence lawyers regularly challenge assault peace officer charges on several grounds:
- Officer not acting in lawful execution of duty: If the arrest was unlawful, the detention arbitrary, or the officer exceeded their authority, a key element of the offence is not established.
- Self-defence (section 34): If the officer used excessive or disproportionate force, you may have the right to defend yourself with reasonable force.
- Lack of intent: If the contact was accidental, for example, during a chaotic arrest, the Crown may not be able to prove the intentional application of force.
- Charter violations: If your rights under sections 8, 9, or 10 of the Charter were violated during the interaction, evidence may be excluded under section 24(2). A violation of your right to counsel can be particularly significant in these cases.
- Mistaken identity: In situations involving crowds, protests, or chaotic scenes, the Crown must prove you were the person who committed the assault.
