Citizen's Power of Arrest (s. 494)

Citizen's Power of Arrest — Criminal Code s. 494

Quick Answer: Section 494 gives every private person — including a security guard — three separate arrest powers plus one duty. s. 494(1)(a) covers anyone found committing an indictable offence. s. 494(1)(b) covers a person reasonably believed to have committed a criminal offence who is escaping from and freshly pursued by someone with lawful authority to arrest. s. 494(2) is the property power a guard uses most: the owner, person in lawful possession, or a person authorized by them may arrest someone found committing a criminal offence on or in relation to that property. s. 494(3) then requires the arrested person to be delivered to a peace officer forthwith.

A security guard is not a peace officer. Every arrest power a guard exercises on the job flows from the same citizen's arrest authority that any member of the public holds under Criminal Code s. 494. Knowing which subsection you are relying on — and its exact limits — is the single most-tested block of material in ABST Module 2.

The Structure of Section 494

---

s. 494(1)(a) — Finds Committing an Indictable Offence

Any person may arrest without warrant someone they find committing an indictable offence.

• "Finds committing" means you personally witness the offence in progress. Arriving after the fact and inferring what happened does not meet the test.
• The offence must be indictable. Under the federal Interpretation Act (s. 34(1)(a)), a hybrid (dual) offence is deemed indictable until the Crown elects, so hybrid offences such as theft under $5,000, assault, and mischief are captured. Pure summary-conviction offences — causing a disturbance (s. 175), for example — are not.
• No property nexus and no escaping requirement. This power applies anywhere, to anyone.

Scenario: Off post and off property, a guard walking to their car sees a man punch a stranger in a parking lot. Assault is hybrid, therefore deemed indictable. The guard has s. 494(1)(a) authority to arrest — although the safer professional choice is usually to observe, record, and call police.

s. 494(1)(b) — Reasonable Belief + Escaping and Fresh Pursuit

Subsection (1)(b) covers the person you did not see commit the offence. It has three cumulative elements, and candidates routinely forget the third:

1. Reasonable grounds to believe the person has committed a criminal offence — any criminal offence, not only an indictable one.
2. The person is escaping.
3. The person is being freshly pursued by persons who have lawful authority to arrest them.

Element 3 is the limiter. A guard who simply believes someone committed an offence and sees them walking away has no s. 494(1)(b) power — nobody with lawful arrest authority is in fresh pursuit. The subsection exists so bystanders can assist an arrest that is already under way.

Scenario: Police chase a robbery suspect past a guard's post and shout for help. The guard, believing on reasonable grounds that the offence occurred and seeing the suspect fleeing from officers in fresh pursuit, may arrest under s. 494(1)(b).

s. 494(2) — The Property Power (the guard's workhorse)

This is the subsection a licensed guard relies on nearly every shift. It authorises the owner, a person in lawful possession of property, or a person authorized by the owner or possessor — which is exactly what a guard is on a client site — to arrest without warrant a person they find committing a criminal offence on or in relation to that property.

• Any criminal offence counts, including a pure summary offence. This is broader than s. 494(1)(a) on offence type but narrower on location.
• The property nexus is mandatory. The offence must occur on, or in relation to, the property the guard is authorised to protect.
• Timing has two branches:
  • s. 494(2)(a) — arrest at that time, i.e. immediately.
  • s. 494(2)(b) — arrest within a reasonable time after the offence, but only if the arrester believes on reasonable grounds that it is not feasible in the circumstances for a peace officer to make the arrest. That feasibility belief is a real element, not a formality.

Scenario: A loss prevention officer watches a shopper conceal a sweater in a backpack, walk past all points of sale, and step through the exit doors. The LPO has found the person committing theft on the property and arrests immediately under s. 494(2)(a).

s. 494(3) — The Forthwith Delivery Duty

Subsection (3) is not an arrest power at all. It is the duty that attaches to every citizen's arrest: any one other than a peace officer who arrests a person without warrant shall forthwith deliver the person to a peace officer.

Forthwith means immediately and without delay.

• Holding a suspect in a back office for an hour while you finish paperwork is not forthwith.
• Questioning the suspect, demanding explanations, or prolonging detention for store convenience violates the duty.
• Call police immediately, and document the time of arrest and the time of police arrival.

Breaching s. 494(3) can convert an otherwise lawful arrest into unlawful detention.

s. 494(4) — The Link to Use of Force

Subsection (4) states, for greater certainty, that a person authorised to arrest under s. 494 is a person "authorized by law" for the purposes of s. 25. That is the bridge between the arrest power and the use-of-force justification: because the arrest is lawful, reasonable force to carry it out is justified under s. 25.

Limits and Liability

A citizen's arrest must be lawful, timely, and proportionate. Getting it wrong creates real exposure:

• Excessive force → criminal responsibility under s. 26 plus civil suit.
• Unlawful detention (no "finds committing", no lawful-authority pursuit, no property nexus) → false imprisonment liability.
• Failure to deliver forthwith under s. 494(3) → the arrest becomes unlawful the moment the delay becomes unreasonable.
• Mistaken identity → civil liability for wrongful arrest, even in good faith.

The golden rule: when in doubt, observe, document, and call police rather than arrest on a hunch.
