Insurance from the dust collector in your shop to the kitchen on your client's wall.
Get a quoteIn short
A woodworker or cabinet shop in Canada needs commercial property for the shop, machinery and stock, rated for wood dust and finishing; equipment breakdown and business interruption for the machines that make the money; and commercial general liability with product and completed operations cover for furniture and millwork you sell or install. Add tools and equipment cover and commercial auto for installation crews, and workers' compensation where your province requires it.

A woodworking business is a small manufacturer and an installation trade at once. The shop holds machinery, lumber and work in progress in a building full of fine dust and flammable finishes, which is why commercial property and equipment breakdown cover sit at the centre of the program. Every piece you sell is a product, and every install puts your crew in a finished home, so commercial general liability must include products and completed operations.
We build programs for custom furniture makers, cabinet and millwork shops and the installers who work with them. We document dust collection and finishing for the property underwriter, add business interruption for the machines that carry the business, and check contract requirements such as CCDC 41 before you bid commercial millwork. See the construction and contractors guide for the wider sector.
A custom woodworking business is a small manufacturer and a finishing trade at once. In the shop, you run saws, planers, CNC routers and edgebanders, generate fine dust and spray flammable finishes. On site, your crew installs kitchens, vanities, built-ins and stairs in finished homes and commercial fit-outs. The insurance has to follow both.
That is why a woodworker's program looks different from a carpenter's. A carpenter mostly needs site liability and tools. A cabinet or millwork shop also needs serious commercial property cover for the building, machinery and work in progress, and product liability for every piece that leaves the door. It sits within our construction and contractors sector, but underwriters rate the shop much like a light manufacturer.
Most programs combine a property package for the shop with a liability policy that covers products and installation.
| Coverage | What it answers | Points to check |
|---|---|---|
| Commercial property | Fire, smoke, theft or water damage to the building, machinery, lumber, sheet goods and finished pieces | Replacement cost; separate limits for work in progress and customers' goods; dust collection and spray booth details on the application |
| Equipment breakdown | A CNC router, edgebander, dust collector or compressor fails electrically or mechanically | Covers what property policies exclude; see equipment breakdown |
| Business interruption | Lost income and extra expense while the shop is rebuilt or a key machine is replaced | Indemnity period long enough to replace specialized machinery; see business interruption |
| Commercial general liability (CGL) | Injury or damage at your shop, or at a client's home during installation | Products and completed operations included; see commercial general liability |
| Tools and equipment | Portable tools, jigs and installation gear stolen from the van or a job site | In-vehicle theft conditions; see tools and equipment |
| Commercial auto | Delivery and installation vehicles carrying finished cabinets | Business use declared; goods in transit; see commercial auto |
Makers who sell through markets and craft fairs should check the event's insurance terms, covered in our craft show guide. A home workshop needs its own cover, because a homeowner's policy restricts business property and liability. A home-based business policy or a commercial package closes that gap.
Property underwriters look hardest at dust and finishing. The Canadian Centre for Occupational Health and Safety names woodworking facilities as workplaces at risk from combustible dust. It explains that a dust explosion needs fuel, an ignition source and oxygen, plus dust suspended in the air at an explosible concentration and confinement. A first explosion can shake loose dust that has settled elsewhere, and that secondary explosion is often more destructive than the first.
A clean, well-described shop can win better property terms.
A fire policy pays when something outside the machine damages it. It does not pay when the machine fails on its own: a burnt-out spindle motor, a fried CNC controller, a power surge through a control board. That is equipment breakdown cover, and for a shop that depends on one CNC router or one wide-belt sander, it is often the coverage that keeps the doors open.
Pair it with business interruption that responds to breakdown as well as fire. Specialized machines can take weeks to source and install, and the policy should pay lost profit and extra expense, such as outsourcing panels to another shop to meet an installation date. Our post on equipment breakdown walks through how the two coverages fit together.
Every table, chair, bunk bed and cabinet you build is a product. If it collapses, tips or splinters and someone is hurt, the claim is a products liability claim, and in Canada it can be made against anyone in the chain who could be liable, with manufacturers usually held to a higher duty of care than retailers.
Our post from kitchen table to store shelf explains product liability for small makers in more detail.
The scenarios below are hypothetical, but they reflect the questions underwriters ask woodworking shops and millwork installers.
| Hypothetical scenario | Allegation or loss | Policy that responds |
|---|---|---|
| Dust in a collector ignites overnight and fire spreads through the shop | Building, machinery, stock and three kitchens in progress destroyed | Commercial property, with business interruption for lost income |
| The shop's CNC controller fails after a power surge | Repair cost and three weeks of lost production | Equipment breakdown and breakdown-triggered business interruption |
| A custom bookcase tips over onto a child months after delivery | Bodily injury from a product without an anchor kit | CGL products and completed operations |
| Installer drills through a water line while fixing upper cabinets | Water damage to the client's finished basement | CGL; the cost of redoing your own cabinets is usually excluded |
| A client's antique chair, left for refinishing, is damaged in the shop | Damage to customers' goods in your care | Customers' goods cover on the property policy; excluded under CGL |
| Finished vanities are damaged when the delivery van is rear-ended | Damage to goods in transit | Inland transit or motor truck cargo cover; auto covers the van, not the load |
Installation turns a shop into a contractor. Your crew works in finished homes, condos and commercial fit-outs, where scratched floors, dented appliances and punctured pipes are the routine claims. Once the work is handed over, completed operations cover follows it, so a wall unit that pulls out of the drywall a year later is still on your policy.
Watch the faulty workmanship gap. CGL pays for damage your work causes to other property, not to correct the work itself. On larger projects the owner or general contractor may carry builder's risk, which covers the project during construction, and you need to know whether your installed millwork is included and what deductible could be charged back to you. Renovation clients may expect you to coordinate with their renovation contractor's insurance as well.
In Ontario, cabinetmaker and general carpenter are prescribed trades under the Building Opportunities in the Skilled Trades Act, 2021, and both require a certifying examination for a certificate of qualification. Neither is a compulsory trade, so certification is voluntary. It still counts with clients and underwriters. Other provinces run their own apprenticeship systems.
Most Ontario businesses with employees must register with the WSIB within 10 calendar days of hiring their first worker. If your installation work is classified as construction, the WSIB requires owners as well as employees to be covered, and general contractors will want proof of your WSIB status before you start. Confirm your classification with the WSIB. Our post WSIB is not enough explains where liability insurance still fills gaps.
Commercial millwork contracts often run under CCDC forms. CCDC 41 (2020) asks the contractor for general liability of $10,000,000 per occurrence, a limit most shops reach through an umbrella, and requires all-risks contractors' equipment insurance without subrogation against the owner. Expect requests to add the owner or general contractor as an additional insured and for a certificate of insurance before you mobilize.
Property premiums are driven by the building's construction and age, sprinklers, the values of machinery and stock, dust collection and finishing practices, heating, alarms and the fire protection in your area. Liability is usually rated on revenue or payroll, with shop manufacturing, retail sales and site installation rated separately. Furniture for children, seating and beds is rated higher than casework.
Underwriters adjust for subcontracted installation, US sales, years in business, certification and claims history. Contracts that demand umbrella limits or long completed operations periods add premium. A detailed machinery schedule and a well-documented dust and housekeeping program usually do more for the price than any discount.
Three choices are worth pricing before renewal. First, the business interruption indemnity period: twelve months costs more than six, but a specialized machine with a long lead time can outlast a short period. Second, the deductible on property and breakdown, which trades premium against the cash you can absorb. Third, the completed operations limit, which should match the largest contract you expect to sign rather than the one you signed last year.
