Construction site security in Ontario targets the after-hours theft of tools, copper, equipment and catalytic converters, usually combining a night post with mobile patrol or camera towers.
In Ontario, demand for construction site security is driven by a central Inland Empire logistics hub anchored by Ontario International Airport and sprawling distribution centers. The sectors that most rely on this service include warehousing and logistics, aviation and airport, distribution, with specific needs in areas such as Ontario International Airport and its logistics campuses, Ontario Mills and the retail district, the industrial parks along the I-10 and I-15. The city's main security concerns — cargo and warehouse theft and airport-adjacent logistics security — make working with a licensed, professional provider a priority investment for businesses and homeowners.

Armed officers typically run about 35% more than unarmed coverage for the same post — the premium covers the firearm permit, range requalification and the higher insurance the provider carries. In Ontario that puts an armed post around $11,000 — $18,000 USD per guard post/month.
Priced like standard guard posts, typically weighted to nights/weekends when theft risk peaks. Many sites combine a night post with mobile patrol or camera monitoring to cut cost.

Before you hire
Construction sites lose an estimated $300M–$1B a year to theft, and an injured trespasser can be a bigger risk than the loss. Here's how to protect a site — guards, patrol, cameras — what it costs, and the attractive-nuisance liability you can't ignore.
Read the construction site security buyer's guidePrivate security in California is licensed at the state level by the California Bureau of Security and Investigative Services (BSIS), Department of Consumer Affairs. A legitimate company operating in Ontario holds a Private Patrol Operator (PPO) license, which means it has cleared California BSIS's ownership, background-check and insurance requirements. Ask for that license number in writing and verify it yourself — a certificate on the wall tells you nothing about current standing, since a license can be suspended or revoked.
Hiring an unlicensed company is a risk you carry. In California, operating without a license is misdemeanor (Cal. Business & Professions Code §7582.3). Operating as an unlicensed private patrol operator (or knowingly engaging a non-exempt unlicensed one) is a misdemeanor punishable by a $5,000 fine, up to one year in county jail, or both; falsely holding oneself out as licensed (badge, ID/business card, letterhead, or advertising) is a separate misdemeanor with a fine up to $10,000, and a conviction bars BSIS licensure for one year (five years on a second offense).
