Request a Locate in Markham
Finding and marking the buried lines on the owner side of the meter, the ones a one-call ticket does not cover.
In Markham, Ontario — population 338,503, with buried infrastructure laid down over decades and recorded unevenly — private utility locating is how a site gets read before anyone breaks ground. Local construction, telecommunications, utilities work drives most of the demand.
A one-call ticket brings out the member utilities, and each marks the public lines it owns, stopping at the meter, the pedestal, or the edge of the right-of-way. Private utility locating covers everything past that boundary: the water service running to the building, the gas run out to a shop or generator, site lighting and sign circuits, irrigation mains, sewer and septic laterals, and the power and fiber feeding a second structure. A private locator is hired by the property owner rather than by the utility, works the whole site rather than one company's assets, and pairs an electromagnetic locator with a ground penetrating radar cart because neither instrument finds everything on its own.
Project-planning data for Markham, ON — soil, climate, and regulatory factors that shape how locating crews scope work in this market.
Markham sits in a humid continental climate, with winter ground freeze reaching 48 inches — frost changes what ground penetrating radar returns, and it stops paint from bonding, so cold-season work leans on recorded offsets and coordinates. Local ground: Clay, Loam. Soil conductivity is the variable that decides how much of a locate radar can contribute, because conductive ground absorbs the radar pulse instead of reflecting it. Primary industries — construction, telecommunications, utilities — drive steady demand for private utility locating across the York County area.
Ontario One Call (1-800-400-2255) requires advance notice — confirm the exact period with them before any excavation in Ontario. That notification is free and it is separate from private utility locating: it brings out the member facility owners to mark the lines they own, and stops at the meter or the right-of-way. Wait for every member to respond before ground is opened.
Locating is quoted per job rather than off a rate card, because the work is a search and a search scales with the site rather than with the clock. On a Markham job, the things that move the number are how much ground has to be covered, how many targets are in play, whether there are meters, valves, risers, or panels a transmitter can be clipped to, what the lines are made of, what the local ground (clay, loam) does to the instruments, and whether you need surface marks or a record you keep.
