Construction Site Security in Vancouver: Theft Prevention, Access Control, and Overnight Coverage
What gets stolen from Vancouver job sites and when, access control that survives a full trade list, and what overnight coverage should report back to you.
By Akash Sidhu
Owner and Managing Director, Onward Security
Construction site security in Vancouver comes down to three things: controlling who gets through the gate, putting someone on site during the hours nobody is working, and writing down what happened so the next shift and your insurer both have a record. Most losses on Vancouver projects happen overnight, on weekends, and during the long gaps in the schedule when a site sits full of material and empty of people.
This is written for site supers and project managers running work in the City of Vancouver and the surrounding municipalities.
What gets stolen from Vancouver construction sites, and when?
The pattern is consistent across the region, and it follows what is easy to carry and easy to sell.
Tools go first. Cordless tools, generators, compressors, and anything stored in a job box that can be moved by two people. Copper and wire come next, stripped from electrical rooms and partly finished floors once the trades start running feed. Lumber and sheet goods go from open sites where material is stacked outside the fence line. Appliances and fixtures go late in the schedule, when units are finished but not occupied.
The timing is predictable. Friday night through Sunday morning is the longest unwatched window on most projects. Statutory holidays are worse. Sites that shut down for a trade gap or a weather delay are the most exposed, because the schedule says nothing is happening and the site tells anyone walking past the same thing.
There is one thing worth knowing about metal specifically. Under BC's Metal Dealers and Recyclers Act, dealers must record the seller's details and report their purchases to police by the end of the day, or before noon the next day. If metal comes off your site and you can describe it accurately, there is a paper trail to match it against. That only works if someone wrote down what was on site in the first place, which is a reporting problem before it is a policing problem.
What access control actually works with 50 trades on site?
Not a clipboard nobody reads. The version that works on a busy Vancouver site is narrow and boring.
One gate in, one gate out. Every additional opening in the hoarding is another thing to watch. Downtown tower sites usually have this by default because the site is tight. Suburban subdivisions in Surrey, Langley, or Coquitlam often have four ways in because the lot is open, and that is where control breaks down.
A log that records the trade, not just the name. "Dave, 7:10" is useless three weeks later. The company, the trade, the time in and the time out, and the vehicle if one came on site. That is the record that answers who was near the electrical room on the day the wire went missing.
Delivery verification. Deliveries are the most common way material leaves a site legitimately and illegitimately in the same week. The guard should check the delivery against what the site expects, and record what actually came off the truck.
A stated rule on tailgating. Tailgating is the failure mode on every construction gate: one worker badges or signs in, three walk in behind them. The fix is a guard who is allowed to stop the second and third person, and a super who has told the trades that this will happen. If the guard has not been given that authority in writing, they will not use it, and your gate log becomes fiction.
A current list of who is allowed on site. Trades change weekly. The guard needs the current list and a named person to call when someone shows up who is not on it.
Overnight coverage: static guard or mobile patrol?
A static guard is on site the whole shift. Mobile patrol arrives several times a night on a route that covers other properties. Both are legitimate, and they protect against different things.
Patrol suits a site that is genuinely closed, with nothing stored outside and nothing worth the trip. The value is a documented check and a marked vehicle showing up at times nobody can predict.
A static guard is what an active Vancouver site with stored material needs. The gap between patrol visits is the whole opportunity. If your generator walks at 2:40 a.m. and the patrol arrives at 3:15, you have a very well-documented record of a theft that already happened.
The honest test: list what is on site overnight this week, and decide whether you would accept losing it in the window between two patrol visits. If the answer is no, you want someone there.
How should guards report and hand over at shift change?
The handover is where most security contracts quietly fail. A guard who finds a cut in the fence at 4 a.m. and goes home at 7 without telling anyone has done nothing for you.
What you should expect in writing:
- a shift log with start and end times, patrol times, and gate activity
- anything out of place, with the time it was found and where
- a written incident report within 24 hours when something happens
- a handover note that the next shift and the site super both read
- photos of any damage, fence breach, or missing material
There is a regulatory reason this matters beyond your own records. A guard alone on your site overnight is a lone worker under the WorkSafeBC rules on working alone or in isolation. The employer must have a written procedure for checking on that worker, including the interval between checks and what happens if the worker cannot be reached, plus a check at the end of the shift. Ask your security provider to show you that procedure. A company that cannot produce one is running your overnight coverage without a safety plan, and that is a reasonable thing for a general contractor to care about.
When do you call 911, and when is it a non-emergency report?
Get this straight with your guard before the first night, because guessing wastes time in both directions.
Call 911 when something is happening now. The VPD guidance is emergencies that need an immediate response, including a crime in progress or anyone in danger. Someone cutting the hoarding at 2 a.m. is a 911 call.
Use the non-emergency line at 604-717-3321 when the event is over and there is no suspect on scene. A theft discovered at 6 a.m. with nobody around is a non-emergency report. VPD also takes online reports for non-violent incidents with no suspect, including stolen property and vandalism under $25,000, which covers a lot of what happens on a job site.
Write both into the post orders. The guard should know which one applies and who on your team gets called either way.
What should you tell your security company before the first night?
Send this before anyone quotes the work:
- the address, the stage of construction, and the expected duration
- coverage hours, including weekends and statutory holidays
- every gate and opening in the hoarding, and which ones are meant to be locked
- what is stored on site overnight and where
- the trade list and who updates it
- the escalation contact, and who is reachable at 3 a.m.
- any general contractor requirements for site orientation or safety tickets
That last one matters more on Vancouver tower sites than people expect. Many general contractors require a site-specific orientation before anyone works inside the hoarding, and some require construction safety training. Ask your provider whether their guards already hold it, because finding out at 11 p.m. on the first night is an expensive way to learn.
Every Onward guard holds a valid BC security worker licence, and the company holds a security business licence under the Security Services Act. Coverage includes shift logs, a supervisor check-in on every shift, and a written incident report within 24 hours when an incident occurs.
If the project includes a public opening, a sales centre, or any event on or beside the site, that is staffed differently again and the Vancouver event security guide covers the permit side of it.

Common questions
- How many guards does a Vancouver construction site need?
- Most sites with a single controlled gate need one guard per shift. You need more when the hoarding has several openings, when the perimeter is too large to watch from the gate, or when someone has to hold the gate while another guard patrols. A site walk settles it faster than a phone estimate.
- How do I know the guard was actually on site all night?
- Ask for the evidence, not the assurance. Timed patrol records, gate log entries through the night, and a supervisor check-in on every shift give you a trail you can audit against your own door logs and cameras. Spot-check it in the first two weeks. A guard who signs in at 11 p.m. and produces nothing until 7 a.m. was not working an eight-hour shift.
- Is my guard working other sites during the same shift?
- Ask, and get it in writing. Some providers treat guards as contractors and let them stack several sites in one night, which means your eight hours of coverage is really a series of short visits. Ask whether guards are employees, whether anyone else is on their schedule during your hours, and what the contract says if they are.
- Should a construction site guard be armed?
- No. Construction security in British Columbia is unarmed work. Armed security is a narrow, separately authorized category and it is not what a job site needs or what insurers expect to see there. Every Onward guard is unarmed.
- Can a security guard detain a trespasser on my site?
- Within limits. Under section 494 of the Criminal Code, a person in lawful possession of property, or someone they authorize, may arrest without a warrant a person found committing an offence on that property, and must hand them to police right away. In practice our guards observe, document, and call police rather than pursuing an arrest. That is deliberate: a guard chasing someone off your site turns a property loss into a liability problem.
- What should a guard's nightly report include?
- Start and end times, patrol times, gate activity, and anything out of place with the time and location it was found. Photos of any damage, fence breach, or missing material. When an incident occurs, a written report follows within 24 hours, plus a handover note the next shift and the site super both read.
- How do you stop tailgating at construction site gates?
- Run a single controlled entry, give the guard written authority to stop the second and third person, and tell the trades in advance that this will happen. The log should record the company and trade, not just a first name. Without that authority in writing, guards will wave people through and the gate log stops being accurate.
- Do security guards need construction safety tickets?
- It depends on the general contractor. Many require a site-specific orientation before anyone works inside the hoarding, and some require construction safety training. Confirm the requirement with your provider before the first shift rather than at the gate on the first night.
- What stops the overnight guard falling asleep?
- Supervision and a check-in schedule, which is also a legal requirement rather than a courtesy. A lone overnight guard is a lone worker under the WorkSafeBC rules on working alone or in isolation, and the employer must have a written procedure for checking on them at set intervals, including a check at the end of the shift. Ask to see that procedure. A provider who has nothing written down is not checking on anyone.
- When should the guard call 911 instead of the non-emergency line?
- Call 911 when something is happening now, such as someone cutting the hoarding or anyone in danger. Use the VPD non-emergency line at 604-717-3321 when the event is over and there is no suspect on scene, and use online reporting for non-violent incidents with no suspect. Write both into the post orders.
