Retail Loss Prevention: Methods That Actually Reduce Shoplifting
Retail Loss Prevention: Methods That Actually Reduce Shoplifting
Written by Paul Thandi, Operations Manager, On Guard Security Ltd. — 10+ years in BC security · Updated September 2026
Every store owner has seen it: stock that should be on the shelf isn't, and the numbers at count time don't match the sales. Some of that gap is shoplifting, some is internal, and some is plain paperwork error. Retail loss prevention is the discipline of closing that gap without turning your store into an unwelcoming place to shop. This guide covers the methods that work for independent stores and chains in Surrey and across BC, how guards and loss prevention officers fit in, and what the law allows when someone is caught stealing.
Key takeaways
Retail loss prevention combines store design, staff habits, technology and people; no single tool solves shrink on its own.
The cheapest methods are often the most effective: clear sightlines, greeting every customer and consistent receiving and refund procedures.
Cameras and EAS tags support loss prevention but rely on people to act on what they detect.
Uniformed guards deter; plain-clothes loss prevention officers detect and document. Many stores use both at different times.
Under the Criminal Code, a store owner or someone the owner authorizes may arrest a person found committing an offence on the property, but must hand them over to police right away and use no more force than necessary.
Retail loss prevention is the set of practices a store uses to reduce shrink, meaning inventory lost to theft, fraud, damage or error, while keeping the store safe for staff and customers. It covers how the floor is laid out, how staff are trained, which technology is used, who is on the floor watching, and how incidents are recorded and followed up.
The point of retail loss prevention is prevention first. Catching a shoplifter at the door is the most visible part of the job, but it's also the riskiest and the least efficient. A store that makes theft harder and less appealing loses less stock and has fewer confrontations to manage.
Before choosing methods, it helps to know what you are trying to stop. Loss in a typical store falls into four broad sources:
External theft — shoplifting by individuals or organised groups, and refund fraud.
Internal theft — staff taking stock, cash or discounts they aren't entitled to.
Administrative and process error — mis-scans, pricing mistakes, receiving errors and miscounted deliveries.
Vendor and damage loss — short deliveries, damaged goods and spoilage.
The mix is different for every store. A convenience store, a pharmacy and a clothing boutique will each see a different pattern, which is why a loss prevention plan should start with your own counts and incident records rather than a generic checklist.
Key insight: if you don't know which of the four sources is costing you most, spend your first month measuring rather than buying equipment. Good records are the cheapest loss prevention tool there is.
These are the methods we see make the biggest difference in BC stores. Most are low cost, and they work best in combination.
Design the floor for visibility. Keep shelving low enough that staff can see across the store, place high-risk items near the counter or in view of staff, remove blind corners, and keep the entrance and fitting rooms visible from a staffed point.
Greet and engage every customer. A friendly greeting at the door and staff moving through the aisles is good customer service, and it also tells anyone considering theft that they have been noticed.
Train staff on clear, safe procedures. Staff should know what to watch for, what to do when they suspect theft, and, just as important, what not to do. Chasing or grabbing someone is never part of a cashier's job.
Tighten cash, refund and receiving controls. Receipt-only refunds, manager approval for voids and overrides, and checking deliveries against invoices close many internal and administrative gaps.
Use EAS tags and secured displays. Electronic article surveillance tags, locked cases and spider wraps on high-value items slow thieves down and give staff a reason to approach.
Use cameras as a complement. Visible cameras and a monitor at the entrance support deterrence and give you evidence after the fact. They don't stop anyone on their own; someone still has to watch and respond.
Put trained security on the floor. A uniformed guard or a plain-clothes loss prevention officer adds deterrence and a trained response. More on the choice between them below.
Record every incident and review the patterns. Times, items, methods and descriptions help you adjust staffing, layout and security hours to match where the loss is really happening.
Stores often ask whether a uniformed guard or a plain-clothes loss prevention officer is the better choice. They do different jobs. The BC Security Services Act includes performing services to prevent the loss of property within its definition of security guard service, so both roles are covered by provincial licensing when provided by a security company.

Many retailers use both: a uniformed guard during peak hours and a loss prevention officer on days when a pattern of theft has been identified. If you're hiring for the role directly or through a provider, our guide to hiring a loss prevention officer in BC goes into more detail. Shopping centres with several tenants often share coverage through mall and plaza security.
This is where retail loss prevention needs the most care. Security guards and loss prevention officers are not police and don't have police powers. What they have is the same arrest power available to private citizens and to property owners and people they authorize, set out in section 494 of the Criminal Code.
Anyone may arrest without a warrant a person they find committing an indictable offence.
The owner of property, or a person authorized by the owner, may arrest someone they find committing a criminal offence on or in relation to that property, either at the time or within a reasonable time afterwards if they believe on reasonable grounds that it isn't feasible for a peace officer to make the arrest.
Anyone other than a peace officer who makes an arrest must deliver the person to a peace officer forthwith, in practice by calling police immediately.
Use of force is limited as well. Section 25(1) of the Criminal Code justifies a person acting on reasonable grounds in using only as much force as is necessary for what they are authorized to do. In practice, that means the officer must have actually seen the offence, must act on reasonable grounds, and must never use more force than the situation strictly requires.
Key insight: an arrest is a legal act with real risk for the store. A good loss prevention policy sets a high bar for making one, and treats "let it go, record it and report it" as a perfectly acceptable outcome when stopping someone would be unsafe.
This is general information, not legal advice. Your store's policy should be written with your legal adviser and your security provider, and every officer on your floor should be trained on it.
Good records do three jobs. They show you where and when loss is happening, so you can put staff and security where they count. They support police reports and insurance claims. And they protect the store if an incident is later questioned, because a clear, timely written account is far more reliable than memory.
At minimum, every incident report should record the date and time, location in the store, what was seen, who saw it, what was taken or recovered, the actions taken and whether police were called. Over a few months, those reports become the most useful loss prevention tool you have.
A practical plan for an independent store or small chain usually follows these steps:
Measure your current shrink and sort incidents by source.
Walk the store with fresh eyes and fix sightlines, displays and entrance layout.
Write a short, clear staff procedure for suspected theft, including when not to intervene.
Tighten refunds, voids and receiving.
Protect your highest-risk products with tags, cases or counter placement.
Add trained security during the hours your records show are highest risk.
Review incident reports monthly and adjust.
Stores that close in the evening can also add after-hours mobile patrol checks for break-ins and loitering, which covers a different kind of loss than daytime shoplifting.

Retail loss prevention is the set of practices a store uses to reduce inventory lost to theft, fraud, damage and error while keeping staff and customers safe. It combines store layout, staff training, procedures, technology such as EAS tags and cameras, trained security staff and incident reporting.
What are 5 methods of loss prevention in retail?
Five widely used methods are designing the floor for clear sightlines, greeting and engaging every customer, tightening cash, refund and receiving controls, protecting high-risk items with EAS tags or locked displays, and placing trained security on the floor during high-risk hours. Recording every incident ties them together.
What does loss prevention do in retail?
Loss prevention staff deter and detect theft, watch for fraud and process errors, document incidents, support police reports and insurance claims, and help the store adjust layout, staffing and procedures based on where loss is happening. Uniformed guards focus on deterrence; plain-clothes officers focus on detection.
How can retail stores prevent shoplifting?
Start with visibility and engagement: low shelving, high-risk items near staff, and a greeting for every customer. Add clear staff procedures, EAS tags or locked cases for high-value items, cameras as a complement, and trained security during the hours your incident records show are highest risk.
Can loss prevention detain you in Canada?
Under section 494 of the Criminal Code, a property owner or a person the owner authorizes, such as a loss prevention officer, may arrest someone they find committing a criminal offence on or in relation to the property. They must deliver the person to police forthwith and may use only as much force as is necessary. They do not have police powers.
Do stores actually keep track of shoplifters?
Many do. Stores and their security providers commonly keep incident reports recording dates, times, items and descriptions, and share them with police when a report is made. Those records help the store spot repeat patterns and put staff and security where they are needed.

We used On Guard for our building while we were transitioning to our new intercom and entry system. They were always incredibly professional to deal with and the guards showed up well ahead of time and did a great job as we went through the process, which extended longer than expected. On Guard was also great at getting somebody on site the first night we needed them on very short notice. Overall, we were extremely happy with their service.
