Security guards have lawful functions, but they should not exaggerate them. Their authority depends on legislation, property authorization and the facts of the situation.
At a glance
- Private security does not have general police powers.
- Property authority can support access and trespass functions, while citizen’s-arrest authority is limited by the Criminal Code.
- Exaggerating legal authority can create risk for the guard, agency and client.
What this means in practice
The official rules establish a baseline, but a workable security assignment still needs property-specific decisions. The client and provider should turn general requirements into clear instructions about what is checked, who can authorize exceptions, what must be documented and when another authority takes over.
Questions to confirm
- What authority is the guard relying on in this situation?
- Is the action required by the site instructions?
- Would police or management be the more appropriate next step?
Picture this at your property
A visitor argues with a guard at a private building. The guard should rely on the property’s access rules and lawful directions, not invent a broader power to compel behaviour.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
The strongest security process is usually the one that makes responsibilities, observations and escalation clear. That creates a service that can be understood and reviewed without overstating what security can guarantee.
