Overview: Excavation Services
Excavation contractors dig, grade and demolish. On a house lot, that means opening the ground for a basement or an addition's footings, cutting trenches for water, sewer and hydro lines, and digging out a septic bed. They also haul spoil away, bring in clean fill and take down old garages and sheds.
Frost shapes the work. Footings go below the frost line, frozen ground is slow and costly to break, and a wet spring turns clay into a mess that heavy machines only make worse. A contractor who moves your start date for the weather may be doing you a favour.
Locates come before the first bucket. Ontario makes it a legal duty to request them through Ontario One Call, and in Alberta the requests go through Utility Safety Partners. Both services are free, and neither marks the private lines you own. In BC, it's worth checking your contractor's WorkSafeBC standing too.
Our listings show what each contractor states on its own website, from basement digs and trenching to demolition. Choose your province, then your city, to reach excavators who work on residential lots.
Excavation costs in Canada
Start with a defined dig-and-haul scope. Hourly equipment, transport and disposal figures are cost components, not amounts to add automatically.
| Service | Planning budget | What it covers |
|---|---|---|
| Excavator with operator | C$105–C$180per machine-hour | Compact mini-excavator with operator during regular hours; size and minimum booking confirmed.Machine and operator only. Ask for the minimum billed time, travel and fuel terms before multiplying by hours.What this estimate coversIncludes in this budget: Machine and operator; Specified fuel allowance Budget separately or confirm: Mobilization; Hauling and disposal |
| Equipment mobilization | C$200–C$500per project mobilization | Local delivery and collection of a compact excavator; both directions included in this budget.Confirm both delivery and collection. Long-distance transport and repeated machine moves are extra.What this estimate coversIncludes in this budget: Delivery; Collection Budget separately or confirm: Extra moves; Permit-controlled transport |
| Utility trench excavation and backfill | Scope-based quoteper measured trench scope | Length, width, depth, surface and backfill specified for the chosen utility.A shallow cable trench and a deep water or sewer trench are different jobs. Ask whether backfill, compaction and surface restoration are included. Depth and backfill change both output and cost. Send the route length, required depth and width, soil/access details and restoration needs for an itemized trench quote.What this estimate coversIncludes in this budget: Listed excavation and backfill stages Budget separately or confirm: Utility pipes, cables and licensed connections; Unlisted restoration and disposal |
| New-home basement foundation excavation | C$10,000–C$30,000per defined excavation project | Open-access detached-house lot, ordinary clean soil and excavation for a full basement.For a new-house excavation, not lowering a basement under an existing house. Define volume, shoring and disposal in the quote.What this estimate coversIncludes in this budget: Machine excavation; Agreed clean-soil haul-away Budget separately or confirm: Rock, contaminated soil and major dewatering; Concrete foundation, engineering and permits |
| Clean-soil hauling by tandem dump truck | C$120–C$160per truck-hour with driver | Hauling with a tandem/dual-axle dump truck; haul distance and load capacity specified.Trucking and disposal are separate charges. Minimum hours, travel to site and return travel can be billable.What this estimate coversIncludes in this budget: Truck and driver; Fuel where listed Budget separately or confirm: Receiving-site tipping fees; Soil testing and excavation |
What changes the price
- Access width, equipment size and underground constraints
- Rock, groundwater, shoring and soil suitability
- Haul distance, receiving-site charges and material testing
Ask before accepting a quote
- What excavation dimensions, finished levels and soil volume does your price cover?
- Does the project total already include machine transport, trucks and receiving-site tipping fees?
- How will rock, groundwater or unsuitable soil be approved and charged if discovered?
Choose one pricing basis
- Compare complete project quotes on the same excavation, shoring, haul-away and backfill scope.
- Do not add hourly machinery or truck allowances to a project price that already includes them.
Canadian context
Soil reuse and disposal requirements differ by province; ask which testing and destination requirements apply to the excavated material.
Planning amounts in Canadian dollars. Published tax treatment varies; confirm applicable taxes and the final total in your written quote. Rows can be different services, alternative packages or separately priced extras. Add only work that is needed and not already included in your quote.
Frequently asked questions
Could I owe workers' comp premiums for an uninsured contractor?
In BC, you could. WorkSafeBC says a homeowner who hires a contractor that isn't registered or paid up can be held liable for premiums owed on that work. The fix is a free clearance letter, requested online before the machine arrives and again before the final payment. It confirms coverage only. It says nothing about the quality of the digging.
What has to happen before anyone digs?
A locate request. In Ontario, it's the law: you request locates through Ontario One Call, the service is free, and for a single property you ask at least five business days before digging. Alberta's requests go through Utility Safety Partners, also at no charge. Only the utilities' own lines get marked. Your septic line, a well feed or the cable to the garage has to be traced some other way.
Why is trench work treated so seriously?
Because a collapse comes without warning and soil is crushingly heavy. Ontario's construction rules keep workers out of any trench past a set depth unless the walls are solid rock, sloped, shored or protected by a trench box. Machines and spoil stay back from the edge. Thawing spring ground and old backfill are the least stable of all. A crew standing between straight, unbraced walls is a crew to send home.
What makes a dig cost more than expected?
Rock, water and soil that won't hold. Bedrock means breaking and extra machine hours, a high water table means pumping, and soft clay often has to come out for granular fill. A winter dig costs more because frozen ground must be broken first. Trucking and tipping fees add up fast, since every load of spoil gets paid for once when it leaves and again at the dump.
What is involved in taking down a garage?
Start with the paperwork. Check whether your municipality requires a demolition permit, and get the utilities disconnected first. In an older garage, Health Canada advises having a professional test for asbestos before work starts, since siding, roofing and cement products can contain it. Then pin down the price below grade: the slab, the footings, any buried fuel tank, and whether the hole gets backfilled and compacted.
Do I need a permit to add fill near a creek?
In Ontario, quite possibly. Conservation authorities regulate work in and near river valleys, shorelines, wetlands and flood-prone land, and that includes grading and placing fill. Their permit comes on top of any municipal approval. Regulated areas don't always show on maps, so call the local conservation authority with your address before the first load of fill arrives.
