Start a demolition business in Canada: pick a niche, clear the municipal permit layer, survey for hazardous materials, and price from waste and labour.
Applies in: across Canada
A demolition business is a permits-and-waste business that happens to knock buildings down. The knocking down is the visible part. The three things that decide whether you survive the first year are the permit layer, the hazardous-materials survey, and disposal. A job that starts without the right permit gets stopped. A job that disturbs asbestos without a plan gets stopped and fined. And a job priced without bin and tipping costs loses money on the waste. Get those three right, pick one niche, and the machines take care of themselves.
Demolition is not one business. The common niches are:
Each niche needs different equipment, different customers, and different insurance. A strip-out crew with hand tools and bins cannot take down a warehouse, and a heavy crew cannot make money on a bathroom strip-out. Start with one niche and add capability only when the work you already have demands it.
A demolition permit from the municipality is normally required before demolition starts, and the application asks for detail: the work, the existing and proposed uses, the land description, plans and documents, and the names of the owner, the applicant, the designer, and the person carrying out the work. Toronto's bylaw requires a deposit with the application, equal to the chief building official's preliminary estimate of the fees or $20,000, whichever is less.
Rental housing carries a second layer in Toronto: rental demolition decisions commonly require the owner to remove all debris and rubble immediately after demolition, erect solid construction hoarding to the chief building official's satisfaction, and erect the replacement building no later than three years from the date demolition of the rental units commences — with $20,000 per dwelling unit entered on the collector's roll, as with municipal property taxes, if the replacement is not built in time. Heritage designation, zoning, and servicing can add further approvals. Check the exact property with the municipality before you promise a start date, and put the permit responsibility in the contract: who applies, who pays the deposit, and what happens if approval takes longer than planned. This section is general information about the regulatory layer, not legal advice.
No survey, no demolition — that is the rule for older buildings. Asbestos, lead paint, mould, and other designated substances each carry their own handling and disposal rules, and the survey decides what your crew can remove, what needs a specialist abatement contractor, and what the disposal site will accept.
Ask for the survey at the quoting stage, not on the first morning on site. If no survey exists, say so in the quote and price the survey, or make the contract conditional on it. A pre-1990 building quoted without a survey is a quote built on a guess, and the guess usually goes the wrong way. Keep the survey, the abatement records, and the waste manifests on file for the job — they are the paper trail that shows the work was done properly.
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, bins, and disposal. If you operate in Quebec, you also deal with QST.
Insurance needs a direct conversation with a broker who knows demolition: commercial general liability, commercial auto for trucks, equipment coverage for machines, and pollution coverage where the work warrants it. Tell the broker exactly what you demolish, how tall, and near what neighbours — a policy written for general contracting may not cover the demolition 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.
Waste is where demolition quotes die. Concrete, wood, metal, drywall, and mixed waste go to different receiving sites at different prices, and a load rejected at the gate costs a second trip plus a reload. Before you quote, confirm each receiving site, its tipping fees, and its acceptance rules for the waste your job will produce. Scrap metal recovery — copper, steel, and aluminum — offsets part of the cost, so decide in the contract who keeps the scrap: you, or the customer.
Separate on site where the price rewards it. A clean concrete load and a clean wood load usually cost less to dispose of than a mixed load, and the sorting labour pays for itself on larger jobs. Put the bin count, the haulage, the disposal fees, and the scrap split in writing, so the customer and the contractor agree on what the price covers.
Demolition work comes from relationships. Builders, renovators, property managers, and general contractors hand out repeat work to crews 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: permits in hand before the start date, dust and noise kept under control, neighbours treated with respect, and a site left clean and graded. Keep a simple record of every job — location, scope, machines used, bins and disposal sites, and the contact who hired you — and ask for the next job while the current one is still going well.

Toronto figures are Toronto's published rules, not a national price list — your municipality's permit fees, deposits, and rental-demolition rules differ. Machines, bins, labour, and disposal dwarf every fee on this table; price those from quotes for your jobs.
No province issues a single demolition 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 the building itself needs a demolition permit from the municipality before work starts. Provincial occupational health and safety rules for construction projects govern the work, including the demolition provisions of Ontario's construction regulation, and some cities add their own demolition approvals — Toronto, for example, runs a separate rental housing demolition process. There is no shortcut around those layers: a business registration alone does not make a demolition legal.
At minimum, a demolition permit from the municipality for the building, applied for with the information the chief building official requires — the work, the existing and proposed uses, the land description, plans and documents, and the names of the owner, the applicant, the designer, and the person carrying out the work. Toronto's bylaw also requires a deposit with the application, equal to the chief building official's preliminary estimate of the fees or $20,000, whichever is less. Rental housing can need more: Toronto's rental demolition decisions commonly require the owner to remove debris immediately after demolition, erect solid construction hoarding, and erect the replacement building no later than three years from the start of demolition — with $20,000 per dwelling unit entered on the tax roll if the replacement is not built in time. Heritage buildings, buildings on serviced lots, and sites needing a variance can add further approvals, so check the exact property before you quote a start date.
Assume an older building may contain them until a survey says otherwise. Asbestos in insulation, flooring, ceiling tiles, and pipe lagging, lead paint, and mould are the usual finds, and each has its own removal, handling, and disposal rules under provincial occupational health and safety and environmental law. A survey by a qualified person, done before demolition, tells you what needs specialist removal, what the crew can handle with ordinary controls, and what the disposal site will accept. Never price a demolition of a pre-1990 building without asking about the survey — the removal cost can exceed the demolition cost, and disturbing asbestos without controls puts workers and neighbours at risk.

From labour, machines, bins, haulage, and disposal, minus scrap recovery. Count the bins and the trips, confirm each receiving site and its tipping fees before you quote, and separate clean concrete and wood from mixed waste where the site prices them differently. Full-structure jobs suit fixed pricing once the survey and the permit are in hand; interior strip-outs with unknown conditions suit a price with a written allowance for what the survey did not cover. Put the permit, survey, disconnection of services, dust control, hoarding, and final cleanup responsibilities in writing, so the customer and the contractor agree on what the price covers.
Interior strip-out work starts with hand tools, a dump trailer or bins, dust control, and a reliable crew — low capital, high labour. Residential full-structure work adds a mini or full-size excavator with a bucket and grapple, a skid steer, and haul trucks. Commercial work needs larger machines, engineered demolition plans for taller structures, and often a specialist subcontractor for the parts your crew should not touch. Rent the big machine for the first jobs and buy once the work you already have demands it. Whatever you run, budget for maintenance, transport, and fuel — a machine that cannot get to the site on time is not an asset.
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, bins, and disposal. If you operate in Quebec, you also deal with QST.
