You did your due diligence. You called One Call. You waited for the lines to be marked. The paperwork’s in, the site’s cleared, and the crew’s ready to dig.
Then, a few feet into the trench, the excavator hits something that shouldn’t be there. Work stops. Someone swears. And everyone suddenly realizes One Call didn’t mark that.
Here’s the reality — One Call only covers public utilities. Everything from the property line inward — from gas to data to water — is on you. That’s what a private locate is for. And if you skip it, you’re gambling your schedule, your profit, and your reputation.
Let’s talk about why every serious contractor in Ontario should make private locates standard practice — not an afterthought.
1. One Call Doesn’t Mark Private Utilities
Most people think “I called One Call — I’m covered.” You’re not.
One Call only locates utilities owned by municipalities or major utility companies — the lines running under public roads and easements. But the minute those lines cross onto private property, One Call stops.
That means anything between the meter and the building — power feeds, gas to outdoor kitchens, irrigation systems, security cables, lighting, comms, and even geothermal loops — are invisible to One Call.
Private locates fill that gap. They identify everything public locates don’t touch, ensuring your dig site is truly cleared before a single bucket hits the ground.
If you skip that step, you’re not “safe.” You’re just lucky — until you’re not.
2. Private Utilities Are Everywhere (and Increasing)
Every year, more private lines get buried on commercial, industrial, and residential properties across Ontario.
Think about how today’s projects are built: solar panels, EV chargers, outdoor lighting, fiber optics, irrigation, data networks — all with their own underground connections. Even a basic plaza or condo site can have dozens of private lines running beneath it.
And if your project is in cities like Hamilton, Kitchener, or Guelph, odds are you’re digging in redeveloped areas with layer upon layer of old, undocumented infrastructure.
A private locate brings clarity to that mess. It maps out everything — not just what utilities admit to owning.
3. The Cost of Damage Dwarfs the Cost of Prevention
A full private locate can be done in a few hours. The cost is predictable, low, and easy to budget. The cost of a hit? Not so much.
When you strike a private line, you don’t just pay for the repair. You pay for lost time, rescheduling, equipment idle costs, possible fines, and sometimes even legal claims. A single incident can erase weeks of profit.
And if you damage something like a fibre line or electrical feed, the downtime doesn’t just hurt you — it affects every tenant or system connected to that line. Those ripple effects can cost tens of thousands.
Bottom line: a locate is cheaper than damage control, every single time.
4. Old Records and Assumptions Can’t Be Trusted
Every site has a story, and most of them aren’t fully documented.
Old blueprints get lost. Maps are copied and redrawn. Utility records are incomplete or wrong. You can’t rely on what’s “supposed to be” underground — because what’s supposed to be there rarely matches what’s actually there.
Modern private locates use advanced tools like ground penetrating radar (GPR) and electromagnetic detection to see what’s real, not just what’s recorded. GPR detects both metallic and non-metallic utilities — PVC, fibre, concrete, even voids or buried foundations — with precision.
That level of certainty is how professional contractors eliminate risk before a project begins.
5. Liability Stops With You — Not One Call
This is the part most crews don’t hear until after the damage is done.
One Call protects the utility owners. Private locates protect you.
If a strike happens on a private line, One Call isn’t liable — you are. They’ll point to their policy, which clearly states that private utilities fall outside their scope.
That means you eat the cost, the delay, and the damage to your client relationship.
Hiring a private locate service shifts that risk back into control. It proves due diligence, protects your company’s liability, and gives you documentation to back it up if anything ever goes wrong.
How Private Locates Fit Into a Smarter Workflow
Let’s be honest — project timelines are tight. Adding another step can feel like another delay. But a private locate doesn’t slow you down. It prevents real delays — the kind that last days, not hours.
Smart site managers now schedule public and private locates together. It’s one visit, one report, full coverage. With the right partner, you can book both in advance and keep your project on track.
That’s the new normal for professional crews across Ontario.
Real-World Example: The “Hidden Line” That Stopped a Build
A contractor in Hamilton was trenching for a new sign base at a commercial plaza. One Call cleared the site. Everything was marked. But two hours into the dig, they hit an unmarked electrical line running to an old parking light.
Work stopped. The plaza lost power. The repair took two days, and the crew had to pay for both the fix and lost rent compensation to the tenants.
That line? Private. Not marked. And completely avoidable.
A private locate would have found it — before a single shovel hit the ground.
There’s No Shortcut for Safety or Certainty
When you rely on One Call alone, you’re only seeing part of the picture. Private locates show you the rest — and that’s the part that saves you.
If you manage crews, coordinate subcontractors, or sign off on digs in Ontario, stop treating private locates like an optional add-on. They’re the difference between a smooth job and a stop-work order.
You can’t control what’s buried underground. But you can control how prepared you are before you dig.
