Start a demolition business in Canada: pick a niche, clear the municipal permit layer, survey for hazardous materials, and price from waste and labour.
How to Start an Excavation Business in Canada
Start an excavation business in Canada: pick a niche, get locates before every dig, meet trenching and shoring rules, and price from haulage and disposal.

The short answer
An excavation business is a safety-and-logistics business that happens to move dirt. The digging is the visible part. The three things that decide whether you survive the first year are locates, shoring, and haulage. A crew that digs without locates will eventually strike something. A crew that cuts corners on shoring will eventually face a cave-in or a stop-work order. And a job priced without haulage and disposal costs will lose money on the truck trips. Get those three right, pick one niche, and the machines take care of themselves.
Step 1: Pick the niche before you buy iron
Excavation is not one business. The common niches are:
- Residential foundations and additions. Footings, foundation walls, backfill, and grading for builders and homeowners. Steady, local, and sensitive to housing starts.
- Service trenching. Water, sewer, gas, electrical, and telecom trenches for utilities and contractors. Smaller machines, tighter tolerances, and more locate work.
- Site preparation. Clearing, stripping, rough grading, and road base for subdivisions and commercial sites. Bigger machines, bigger contracts, and longer payment cycles.
- Demolition support and land clearing. Working alongside demolition contractors or clearing rural lots. Seasonal in some regions and hard on machines.
Each niche needs different machines, different customers, and different insurance. A mini excavator that is perfect for a backyard foundation is useless on a subdivision road. Start with one niche, learn its customers, and add machines only when the work you already have demands them.
Step 2: Get locates before every dig, without exception
No locate, no dig. That is the rule on every job, including small ones, including jobs where the homeowner says they know where everything is.
In Ontario, requesting a locate through Ontario One Call is free and required by law, and a request for a single property project must be submitted at least five business days before digging. Projects covering multiple properties or areas without a civic address need ten business days. Once the request is in, infrastructure owners send representatives to mark buried lines. Locates are generally valid for 60 days from the day you receive them, so schedule the dig inside that window or request again. The City of Brampton notes that Ontario One Call imposes a $10,000 administrative penalty for digging or excavating without marked locates, and further charges and fines may follow from the ministry or the Technical Standards and Safety Authority.
Other provinces run their own one-call centres with their own lead times and rules. Learn the local system, keep the locate paperwork on site, and train every operator to stop work when a mark does not match what the ground shows. Private lines — for example, a gas line from a meter to a pool heater — are usually not covered by a public locate, so ask about them and hire a private locator where needed.
Step 3: Build the trenching and shoring routine into every job
Excavation safety rules are provincial, and they are detailed. Ontario's construction regulation, O. Reg. 213/91, is the worked example: it requires support systems for excavations, with timbering and shoring, prefabricated, hydraulic, and engineered systems as the options. A trench deeper than six metres or wider than 3.6 metres needs an engineered support system designed for the specific location and project, and prefabricated, hydraulic, and engineered systems must be designed by a professional engineer and built, installed, used, and maintained to the design drawings.
Your routine, whatever the province, should cover soil identification, sloping or shoring for the soil type, access and egress for workers in the excavation, spoil placement away from the edge, and the point at which you stop and call an engineer. Put it in writing, train to it, and keep the engineer's opinion on the project while work is in progress where the regulation requires it. This section is general information about the regulatory layer, not legal advice — read the regulation for your province and get professional advice for deep or complex excavations.
Step 4: Register the business and set up tax and insurance
Register the business name in the province where you operate: $60 for five years in Ontario, $40 plus a $30 name request in British Columbia, with other provinces in the same range. Get a Canada Revenue Agency business number, which is free, and register for GST/HST when you pass the $30,000 threshold — or voluntarily before it, so you can claim input tax credits on fuel, machines, and repairs. If you operate in Quebec, you also deal with QST.
Insurance needs a direct conversation with a broker who knows excavation: commercial general liability, commercial auto for trucks, equipment coverage for machines, and pollution or underground-damage coverage where the work warrants it. Tell the broker exactly what you dig, how deep, and near what services — a policy written for general contracting may not cover the excavation exposure you actually carry. If you hire workers, workers' compensation registration in your province is mandatory, and general contractors will ask for a clearance certificate before you set foot on their sites.
Step 5: Price from machine hours, haulage, and disposal
The quote that loses money is the one that counts digging hours and forgets everything else. Build every quote from:
- Machine hours for each machine on site, including transport to and from the job.
- Labour hours, including the operator, the labourer, and the supervisor where the job needs one.
- Haulage: the number of truck trips, the distance, and the time each round trip takes.
- Disposal: the receiving site, its tipping fees, and whether the soil is clean fill or needs special handling.
- Restoration: backfill, compaction, topsoil, seeding or sod, and driveway or sidewalk repair where the work disturbs them.
Confirm the disposal site before you quote. A site that closes, fills up, or rejects a load mid-job turns a profitable week into a loss. And state in writing who owns the locate, shoring, backfill, and cleanup — the argument you avoid in the contract is the one you do not have on site.
Step 6: Win the first jobs through contractors, not ads
Excavation work comes from relationships. General contractors, home builders, landscapers, and utility contractors hand out repeat work to operators they trust. Your first jobs will likely come as a subcontractor on someone else's project, and that is a good start: it teaches you scheduling, paperwork, and site discipline without the cost of finding every customer yourself.
What earns the second call is unglamorous: locates done on time, grades that match the survey, trenches backfilled and compacted properly, and a site left clean. Keep a simple record of every job — location, scope, machines used, hours, disposal site, and the contact who hired you — and ask for the next job while the current one is still going well.

Starting an excavation business in Canada, in six steps
- Pick the niche before you buy ironResidential foundations, trenching for services, site preparation, and demolition support need different machines and different customers. The niche decides whether your first machine is a mini excavator, a full-size excavator, or a skid steer with attachments.
- Get locates before every dig, without exceptionIn Ontario, a locate request through Ontario One Call is free and required by law, submitted at least five business days before digging on a single property. Other provinces run their own one-call systems with their own lead times, so learn the local system before your first job.
- Build the trenching and shoring routine into every jobOntario's construction regulation requires support systems for excavations, and trenches deeper than six metres or wider than 3.6 metres need an engineered support system designed for that site. Your crew needs a written routine for soil type, sloping, shoring, and when to call an engineer.
- Register the business and set up tax and insuranceRegister the business name provincially, get a Canada Revenue Agency business number, and sort GST/HST and liability insurance before the first job. Excavation carries real third-party and underground-damage exposure, so confirm the policy covers it.
- Price from machine hours, haulage, and disposalQuote from the hours each machine will actually run, the truck trips to haul spoil away, and the tipping fees at the receiving site. A job priced on gut feel loses money on haulage first.
- Win the first jobs through contractors, not adsGeneral contractors, home builders, and landscapers hand out repeat excavation work. One builder who trusts your locates, your grading, and your cleanup is worth more than a month of advertising.

Questions people ask
Do I need a licence to start an excavation business in Canada?
No province issues a single excavation contractor licence, but several layers apply at once. You need the usual business registration and municipal business licence for the cities you work in, and your operators need the training and tickets for the machines they run. The work itself is governed by provincial occupational health and safety rules for excavations, trenching, and shoring, and by the locate system in each province. There is no shortcut around those layers: a business registration alone does not make a dig legal.
What is a locate, and why does it come before every dig?
A locate is the marking of buried utilities on the ground where you plan to dig. Gas, electricity, water, sewer, and telecom lines are all marked through the provincial one-call system. In Ontario, requesting a locate through Ontario One Call is free and required by law. A request for a single property project must go in at least five business days before digging. Locates are generally valid for 60 days from the day you receive them, so schedule the dig inside that window or request again. Digging without marked locates is a bad gamble. A strike can injure a worker, cut services to a street, and draw a penalty. The City of Brampton notes Ontario One Call imposes a $10,000 administrative penalty for digging without marked locates.
What are the trenching and shoring rules I need to know?
Ontario's construction regulation is Ontario Regulation 213/91. It sets out when an excavation needs a support system and what kind. The options are timbering and shoring, prefabricated systems, hydraulic systems, and engineered systems. A trench deeper than six metres or wider than 3.6 metres needs an engineered support system designed for that specific location and project. Prefabricated, hydraulic, and engineered systems must be designed by a professional engineer. They must also be built, installed, used, and maintained to the design drawings. Other provinces have their own excavation rules, with their own depth triggers and support requirements. Read the regulation for every province you work in. Do not carry Ontario's numbers across a border.
What equipment do I need to start an excavation business?
It depends on the niche, and the niche decides the machine. Residential foundation and service-trench work usually starts with a mini or mid-size excavator, a skid steer, a dump truck or dump trailer, and a compactor. Larger site-preparation work needs a full-size excavator, a dozer, and haul trucks. Buying new is rarely the right first move. A well-inspected used machine, or a rental for the first jobs, lets you prove the niche before you carry a loan. Whatever you run, budget for maintenance, tracks or tires, fuel, and transport. A machine that cannot get to the site on time is not an asset.
How do excavation businesses price jobs?
Start with the hours each machine will actually run and the labour hours for the crew. Then count the truck trips the spoil will take and confirm the receiving site and its tipping fees before you quote. Check whether rock, water, or contaminated soil changes the plan, because any of those can turn a straightforward dig into a different job. Fixed-price quotes suit straightforward residential work where you can see the site. Hourly or unit pricing suits work where the ground is unknown. Either way, put the locate, shoring, backfill, compaction, and cleanup responsibilities in writing. That way the customer and the contractor agree on what the price covers before the first bucket of dirt moves.
Do I need GST/HST registration for an excavation business?
Once your taxable supplies pass $30,000 over four consecutive calendar quarters, or $30,000 in a single calendar quarter, you must register for GST/HST and charge it on your services. You have 29 days from the day you pass the threshold to register, and registration is free through the Canada Revenue Agency. Many contractors register voluntarily before the threshold so they can claim input tax credits on fuel, machines, and repairs. If you operate in Quebec, you also deal with QST. This guide is general information, not tax advice — confirm your own position with the Canada Revenue Agency or an accountant.
