A Downtown Edmonton retail manager once watched a security guard chase a suspected shoplifter two blocks down the street, tackle him on the sidewalk, and hold him for twenty minutes before calling police, a sequence of decisions that exposed both the guard and the store to a serious legal claim.
Understanding security guard vs police Alberta authority before an incident happens, not while it is unfolding, is what protects both your business and the guard you have hired. Business owners comparing our on-site guard services need a clear picture of where a guard's authority ends and police authority begins.
This guide breaks down exactly what a security guard can and cannot legally do compared to a police officer in Alberta, and when a situation needs to be handed to Edmonton Police Service, so you know what to expect before an incident tests the boundary.
|
A security guard is a private citizen with SSIA licensing who can observe, document, enforce trespass, and perform a limited citizen's arrest under Section 494 of the Criminal Code. Police are peace officers with broader arrest powers under Section 495, search warrant authority, and Criminal Code enforcement guards do not have. |
What's the Real Difference Between a Security Guard and a Police Officer?
A security guard is a licensed private citizen. A police officer is a peace officer with authority granted under federal and provincial law that a guard simply does not have, regardless of training, experience, or how the uniform looks.
This distinction is not a technicality. It determines what actions are legally defensible if a guard intervenes in an incident, and it is the single most important thing a business owner should understand before assuming a security contract covers every possible scenario.
Both roles matter, and neither replaces the other. A well-trained guard prevents and deters far more incidents than most businesses realize, but that value comes from working within clear legal limits, not from acting as an unofficial extension of the police.
What a Security Guard Can Legally Do in Alberta
Under Section 494 of the Criminal Code of Canada, a security guard may perform a citizen's arrest if they witness a crime in progress or have reasonable grounds to believe one just occurred on the property they are protecting. This authority is identical to what any private citizen holds, not a special police-like power.
The Supreme Court of Canada has confirmed that private security guards derive this power from the same section of the Criminal Code as any member of the public, not from a separate grant of police-like authority tied to the uniform or the job title.
Guards can observe, document, and report. This is the core, universal function of the role: monitoring a property, recording incidents in detail, and providing that documentation to police or in court if needed.
Guards can use reasonable force under Section 25 of the Criminal Code, but only the minimum necessary to control a situation or complete a lawful citizen's arrest. Force beyond what is reasonable exposes the guard, and the company employing them, to criminal and civil liability.
Guards can enforce trespass on the property they are hired to protect. Under the Trespass to Premises Act (Alberta), a guard can ask someone to leave and, if they refuse, treat continued presence as an offence, working alongside police rather than replacing them for enforcement.
This trespass authority is specific to the property under contract. A guard's ability to ask someone to leave and document a refusal does not extend to public streets, sidewalks, or neighbouring properties outside the boundary they are actually employed to protect.
Guards can escort, evacuate, and control access. Directing people during an emergency evacuation, managing entry points, and enforcing a property's posted rules all fall within a guard's normal, legal scope of duties.
Guards can also seize and temporarily hold property connected to a lawful citizen's arrest, such as an item a shoplifter attempted to take, though the item must generally be turned over to police as evidence rather than kept or disposed of by the guard or the business.
What a Security Guard Cannot Legally Do
A security guard cannot search a person or their belongings without consent or a lawful citizen's arrest. Even then, any search must be reasonable and narrowly limited to immediate safety concerns, not a general search for evidence the way police can conduct under a warrant.
A guard cannot detain someone indefinitely or for extended questioning. Once a citizen's arrest is made, the person must be handed to police without unreasonable delay. Holding someone longer than necessary can expose the guard to a false imprisonment claim.
A guard cannot enter a private residence without consent, except in narrow emergency circumstances. This limitation matters especially for guards working condo or apartment properties, where a resident's unit is legally distinct from the building's common areas.
A guard cannot impersonate a police officer. Presenting oneself as having police authority, using insignia in a way that implies powers a guard does not have, is itself unlawful, separate from anything else that might happen during an incident.
These limits exist for a clear reason. Police officers accept extensive additional training, oversight, and accountability structures in exchange for their broader authority, none of which a private security role, however well trained, is designed to replicate.

What Police Can Do That Security Guards Cannot
Police officers hold arrest powers under Section 495 of the Criminal Code, considerably broader than the citizen's arrest authority available to guards, allowing arrest based on reasonable grounds without directly witnessing the offence in many circumstances.
Police can obtain and execute search warrants, compel identification in specific legal circumstances, and pursue a full criminal investigation, none of which fall within a security guard's authority regardless of training or experience level.
A guard who wants to search a bag or vehicle beyond what consent or a lawful arrest allows has one option: request that the person remain, and call police to take over. Attempting to compel a search directly crosses from a citizen's arrest into a separate legal violation.
Police carry firearms and specialized use-of-force options as part of their role as peace officers, authority tied to their position under policing legislation rather than anything available through SSIA licensing or private security training.
Edmonton Police Service also holds investigative authority that continues well past the point where a guard's role ends. A guard documents and hands off; police investigate, lay charges, and carry a case through the justice system.
Police officers are also bound by, and protected by, a distinct legal accountability framework, including Charter of Rights considerations that apply differently to state actors like police than to private citizens acting in a security role.
When Should a Security Guard Call Edmonton Police Service?
Call Edmonton Police Service immediately for any crime in progress involving violence, a weapon, or a serious injury. A guard's job in these situations is to ensure safety and gather information, not to intervene physically beyond what protects people from immediate harm.
Call police for any situation exceeding a guard's training or authority, including a suspect who resists a citizen's arrest, a medical emergency beyond first aid, or a dispute that has already escalated past verbal de-escalation.
Call police before a situation requires an extended detention. If a citizen's arrest has been made and police response is delayed, the guard's obligation is to minimize the time and manner of detention, not to hold the situation open indefinitely while waiting.
Call police for any situation involving a minor, a person in visible mental health crisis, or anyone appearing to need medical attention rather than law enforcement intervention alone, since these situations often benefit from a coordinated response rather than a guard acting on judgment alone.

Guards are trained to observe, document, and request police support rather than escalate a situation alone. A guard's value comes from deterrence and documentation, not from acting as a substitute for Edmonton Police Service. |
How Canadian Shield Security Trains Guards on These Legal Limits
Every Canadian Shield Security guard completes the mandatory Alberta Basic Security Training curriculum covering legal authority and its limits, then receives site-specific direction on exactly when a situation should be handed to Edmonton Police Service rather than handled independently.
Post orders for every property specify de-escalation as the default response, with physical intervention authorized only within the narrow bounds of a lawful citizen's arrest and reasonable force, never as a first option.
Supervisors review incident reports specifically for situations where a guard's actions approached the edge of their legal authority, using those reviews to reinforce training rather than waiting for a legal complaint to surface a gap.
New officers are walked through real, anonymized examples of both correct and incorrect responses to common scenarios, including the shoplifting-pursuit pattern described at the start of this guide, so the lesson is concrete rather than abstract.
Why This Distinction Matters When Hiring Security for Your Property
Understanding these limits protects your business as much as it protects the guard. A property owner who expects a guard to act like police, physically restraining and interrogating suspects, is setting up a liability exposure that a properly trained, properly directed guard is specifically trained to avoid.
This matters most at the moment a contract is signed, not after an incident. Ask any prospective provider how their post orders address citizen's arrest limits and when guards are directed to call police, and treat a vague answer the same way you would treat a vague answer about licensing or insurance, as covered in our how to choose a security company guide.
The right expectation is a guard who deters, documents, and de-escalates, handing off to Edmonton Police Service the moment a situation exceeds what private security authority actually allows under Alberta and federal law.

Frequently Asked Questions
Can a security guard arrest someone in Alberta?
Yes, but only under narrow conditions. Under Section 494 of the Criminal Code, a security guard may perform a citizen's arrest if they witness a crime or have reasonable grounds immediately after it occurs. Unlike police, guards must hand the person to law enforcement without delay and cannot detain someone for extended questioning.
Does an SSIA licence give a security guard police powers?
No. Under the Security Services and Investigators Act (Alberta), a licensed security guard is trained in Alberta Basic Security Training and holds an SSIA licence, but this does not grant police powers such as search warrants, broader arrest authority under Section 495, or firearms use. Guards remain private citizens under Canadian law for arrest purposes.
When should a security guard call Edmonton Police Service?
Call Edmonton Police Service immediately for any active crime in progress, a weapon involved, a medical emergency beyond first aid, or any situation where a guard's safety or the safety of others is at risk. Guards are trained to observe, document, and request police support rather than escalate a situation alone.
Can a security guard search my bag or vehicle?
No. A security guard may only search a person with their consent or as part of a lawful citizen's arrest, and any search must be reasonable and limited to immediate safety concerns. Guards cannot conduct the kind of search police can perform under a warrant or broader legal authority.
Does Canadian Shield Security train guards on these legal limits?
Yes. Canadian Shield Security's SSIA-licensed guards serve Downtown Edmonton, South Edmonton, Nisku, Sherwood Park, St. Albert, and Leduc, all trained on the legal limits of citizen's arrest, reasonable force, and when to hand a situation to Edmonton Police Service rather than act alone.
