Excavation Permits & Utility Locates in Cambridge
Before a machine touches the ground in Cambridge, two things have to be in place: Ontario One Call locates and the right permits — which, here, can include the Conservation Authority.
Cambridge has one wrinkle most cities don't: a large share of its residential land sits in the Grand River Conservation Authority's regulated area. So the permit question here has three parts, not two.
1. Utility locates — Ontario One Call
Before any excavation in Ontario, buried gas, hydro, water, sewer and telecom services have to be located and marked. It's free, it's the law, and it takes a few business days. We submit the request and work from current locates on every job. In older Galt and Preston we treat the markings as approximate and hand-dig near them — private lines (a gas run to a pool heater, a hydro line to a garage) aren't covered by One Call, and we ask you about those separately.
2. City of Cambridge permits
Foundation excavation for a new build, addition or garage is covered by the building permit. Significant grade changes or importing fill can need a site alteration permit. A sewer or water service crossing the property line involves the City and the Region of Waterloo for the road-allowance portion. Simple grading around a house or a trench for a conduit usually needs no permit at all.
3. GRCA permits
If the property is in a floodplain, near a river or creek, on a steep slope or near a wetland, the Grand River Conservation Authority has to approve excavation, fill and grade changes — separately from the City. Downtown Galt, Preston along the Speed, and low areas of Hespeler are the usual cases. It adds lead time, so we check the mapping at the first site visit.
Who handles it
We submit the locates on every job. Building permits are typically pulled by you or your builder with our excavation scope attached; we'll prepare what's needed and walk you through the GRCA process if it applies.
Frequently asked questions
How long do locates take in Cambridge?
Ontario One Call's standard is five business days, sometimes faster. We build it into the schedule.
Do I need a permit to dig a trench for a garage hydro line?
The trench itself doesn't; the electrical work needs an ESA notification and inspection by your electrician. Locates are still required.
