CONSTRUCTION SITE SECURITY
Construction Site Security Across
Canada.
Overnight and 24/7 protection for active construction sites. Prevent copper theft, tool loss and unauthorised entry with dedicated licensed officers and GPS-verified mobile patrol.
Construction sites are magnets for copper theft, tool loss, vandalism, and unauthorised entry — and downtime from these incidents costs materially more than the security investment. Contractor Watch Security offers dedicated, uniformed construction security officers who understand OHSA, site safety plans, and how to work alongside trades without disrupting productivity.
From highrise residential to civil roadwork, renewable-energy construction to heritage restoration, our teams bring the reporting rigour that satisfies both the general contractor and the site insurer. Every scope is priced flat-rate, includes officer, dispatch, portal and insurance — no fuel surcharges, no line-item surprises.
RISK PROFILE
The challenges we solve
Copper, catalytic converter and tool theft
The commodity-theft cycle drives repeat targeting of active sites — particularly during long weekends and winter shut-down.
Unauthorised entry after hours
Trespassers, urban explorers, encampments — every unauthorised entry is an OHSA liability event for the GC
Fire-watch obligations during hot work
Welding, cutting and torching windows carry fire-watch obligations from the AHJ and your insurer.
Site-specific safety compliance
Officers must be site-oriented, OHSA-aware, and able to escalate near-misses through your safety hierarchy.
Materials, HVAC and appliance theft
Finished-goods theft close to substantial completion is a distinct pattern that requires post-completion coverage design.
Insurer and GC reporting demands
Written daily reports, incident logs, and photo evidence are non-negotiable — your policy renewal depends on them.

HOW WE DELIVER
Our six-step methodology
01
Pre-mobilisation site walk
We meet the GC on-site, review the safety plan, and identify vulnerability points (copper, HVAC, fuel, tool cribs).
03
Layered coverage design
Overnight static plus randomised mobile plus weekend/long-weekend coverage — right-sized to the risk.
05
Live dispatch backup
24/7 Canadian dispatch handles escalations. The gate officer never operates alone in a real incident.
02
Written post orders
Site-specific post orders in writing, signed off by the site super before the first officer starts shift.
04
OHSA-oriented onboarding
Every officer completes a documented OHSA orientation and understands near-miss reporting expectations.
06
Weekly cadence & program adjustment
A written weekly report and a monthly executive summary keep the program adaptive to build phase.

Questions our clients ask
How much does construction site security cost in Canada?
Construction security is priced hourly per officer. Overnight-only coverage (12h) typically runs $360–$540 per night. 24/7 coverage runs approximately $1,300–$1,800 per day depending on the number of posts, access-control complexity, and site location. Multi-site portfolios are quoted at blended rates.
Do you provide fire watch during hot work?
Yes. Fire watch is often bundled with our construction security package at a preferential rate. Officers meet NFPA 101 and provincial fire-code expectations with 30-minute continuous patrol logs.
How do you handle unauthorised entry?
Officers document, verbally warn, and — if the individual refuses to leave — escalate to police under the provincial Trespass to Property legislation. Encampments are handled under a compassionate-response SOP that coordinates with municipal outreach where possible.
Do you carry the insurance our GC requires?
$2M CGL as standard, with additional-insured endorsements naming your GC and owner complimentary. Higher limits available on request.
Can you provide security through winter shut-down?
Yes. Winter and long-weekend shut-down coverage is one of our most common scopes. Layered static-plus-patrol coverage is priced flat for the shut-down window.
Are officers trained on WHS / OHSA reporting?
Yes. Every construction-site officer receives a documented OHSA orientation and understands near-miss reporting expectations.
Do you provide a written report for our insurer?
Yes. Every shift generates a signed, time-stamped log and every incident produces a written report inside 24 hours — the exact documentation your insurer will want to see at renewal.
How quickly can you deploy on a new construction site?
Standard deployment is 7–14 days. Emergency short-notice deployments (following a break-in, or during shut-down) can be started within 24–72 hours.
