Ontario law defines a security guard by the work performed: guarding or patrolling to protect people or property. The role is private security—not police work.
At a glance
- Ontario’s PSISA defines a security guard as a person paid primarily to guard or patrol for the protection of people or property.
- Security guards must be appropriately licensed and work within the authority that applies to the assignment.
- Ontario prohibits licensees from falsely holding themselves out as police or performing police-connected duties.
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 duties are actually included in the site instructions?
- Who has authorized the guard to act on the property?
- What situations must be escalated to management or police?
Picture this at your property
A property manager asks a guard to “deal with anything that happens.” A better assignment defines the property, access rules, patrol duties, reporting expectations and escalation contacts instead of relying on a vague instruction.
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.
