A homeowner in Sandy Hill called us in 2023 after her contractor's framer fell off a stepladder and broke his wrist. The framer wasn't an employee. He was a one-man business, no WSIB, working under a verbal agreement. The contractor told the homeowner it wasn't his problem. The framer's lawyer told the homeowner it was, because she was the property owner. She paid tens of thousands in legal fees before the case settled, on top of the renovation she was already paying for.
This is the part of contracting that homeowners almost never think about until it's too late. WSIB and liability insurance are not paperwork. They're the only thing standing between you and a personal lawsuit when something goes wrong on your property.
Here's what each one does, what to ask for, and how to verify both before any work starts.
What WSIB actually is
WSIB stands for Workplace Safety and Insurance Board. It's Ontario's no-fault workplace injury insurance system. Every employer in Ontario who runs a construction business is legally required to register with WSIB and pay premiums based on payroll.
When a worker is injured on the job, WSIB pays the medical costs and lost wages directly. The injured worker doesn't sue anybody. The employer's insurance pays the claim. Premiums go up next year, but the legal exposure to everyone in the chain (employer, homeowner, third parties) is closed off.
The key word is "registered." A contractor that says they have WSIB but isn't actively registered and current on premiums has a piece of paper, not coverage. Coverage exists only if the premium has been paid recently and the account is in good standing.
The clearance certificate
The proof of WSIB coverage is the WSIB clearance certificate. It's a one-page document, generated through the WSIB online portal, that certifies a specific business is registered, current on premiums, and clear to work. Each certificate has an expiry date, usually 60 to 90 days from issue.
Things to know about clearance certificates:
- The certificate is for a specific business name and account number. If you hire ABC Construction Ltd, the clearance must say "ABC Construction Ltd," not the owner's personal name.
- The certificate is dated. A clearance from 8 months ago tells you nothing about today's coverage. You want one issued within the last 60 days.
- The certificate is generated on demand. Any registered contractor can print one in 30 seconds through the WSIB portal. If they tell you they'll "get it to you next week," they're stalling.
- You can verify any clearance certificate yourself through the WSIB website by entering the certificate number. The system tells you whether the account is current.
One clearance certificate covers one business. If your contractor uses subcontractors (a separate framer business, a separate plumber business, a separate cabinet installer), each subcontractor business needs its own current clearance certificate. The general contractor's clearance does not cover them.
The independent operator gap
WSIB has a category called "independent operator": a sole-prop business with no employees. These businesses can register optionally for WSIB or skip it. If a one-person framer or tile guy on your job is an unregistered independent operator, the WSIB protection does not exist for them. If they get hurt on your property, the chain of liability can include you. Always ask whether each individual on site is an employee with WSIB coverage or an unregistered independent. The answer matters.
What liability insurance actually is
Liability insurance is the contractor's coverage against damage they cause to your property or to third parties during the project. It's separate from WSIB, separate from the contractor's own tool insurance, and separate from your homeowner's policy.
Typical residential construction liability policies carry two million dollars in coverage per occurrence, with five-million-dollar policies common on larger projects. The certificate of insurance (COI) is a one-page document showing the policy holder, policy number, coverage amounts, dates of validity, and the broker.
The damage liability insurance covers includes:
- The contractor's framer drives a nail through your hot water line and floods the basement. Liability pays.
- A piece of falling debris from the project hits a neighbour's car parked on the street. Liability pays.
- The contractor's saw catches the corner of your hardwood and damages the floor in an adjacent room. Liability pays.
- A delivery driver knocks over a piece of your patio furniture and breaks the glass top. Liability pays.
What it does not cover:
- Workmanship defects in the contractor's own work. That's covered by the contractor's warranty, not their liability policy.
- Theft from the work zone. Covered by your homeowner's policy in some cases, by the contractor's tool insurance for their own tools.
- Delays. No insurance covers schedule delays.
The "additional insured" clause
Here's the detail most homeowners miss. The certificate of insurance can list you, the homeowner, as additional insured for the project. This is a one-line endorsement the contractor's broker adds at no cost.
What it does: it gives you direct standing on the policy. If something goes wrong and the contractor goes out of business or refuses to claim it, you can claim directly against the policy as an additional insured party. Without that endorsement, you have to chase the contractor first to make the claim, and if they're uncooperative or insolvent, your recourse is gone.
Ask for the additional insured endorsement on the certificate before the project starts. The certificate should name you (the property owner) explicitly, with the project address. A real broker can issue this in an hour. A fake certificate cannot, because there's no real broker to call.
The verification process
Before any deposit cheque is written, do this verification process:
- Request the WSIB clearance certificate for the general contractor. Verify the certificate number on the WSIB portal. Confirm the certificate is current (less than 60 days old) and the account is in good standing.
- Request a list of all subcontractor businesses the contractor will use on your project. For each one, request a current WSIB clearance. Verify each one.
- Request the contractor's certificate of insurance showing two million dollars minimum liability coverage. Note the broker's name and phone number.
- Call the broker. Ask: "Is this policy currently in force?" The broker will confirm with a yes or no. This catches doctored certificates, which exist and which most homeowners never check.
- Request the additional insured endorsement naming you and the project address. The contractor's broker reissues the certificate. Verify the endorsement language with the broker.
- Save all four documents (WSIB clearance for general contractor, WSIB clearances for subs, COI, additional insured endorsement) in a folder. Print copies. Keep them for the duration of the project plus seven years.
The contractor who hesitates when you ask for the WSIB clearance and the additional insured endorsement is the contractor who doesn't have either, or has them in a state they don't want you to see.
What happens when WSIB is missing
If a worker is injured on your property and WSIB coverage is missing somewhere in the chain, you have three problems at once.
Problem one: the worker's medical and wage costs aren't covered by WSIB. Someone has to pay. The worker's lawyer chases the deepest pocket, which is usually the property owner.
Problem two: your homeowner's insurance doesn't pay. Construction-related injury claims are explicitly excluded from standard residential policies. The insurer denies, you write the cheque.
Problem three: the Ministry of Labour can investigate. If they determine the work was being performed by employees without WSIB coverage, the property owner can be cited as a "constructor" under the Occupational Health and Safety Act, with associated fines and liability.
The risk is asymmetric. If WSIB is in place, you pay nothing extra and never hear about it. If WSIB is missing, you can lose your house. The verification cost is 20 minutes of your time. The exposure cost is six figures.
What about cash deals
The cash discount is the oldest gambit in the renovation industry. The contractor offers a sharp price if you'll pay in cash without paperwork. The implicit promise: HST savings, simpler accounting.
The actual structure: no contract, no insurance, no WSIB, no warranty paper trail, no recourse. You have a piece of work and a memory of paying for it. If anything goes wrong, no insurance company recognizes the relationship. CRA will eventually flag the contractor, and if they get audited, your project becomes part of their evidence stack.
The HST "savings" on a cash deal is a small percentage of the job. The exposure on a single workplace injury claim with no WSIB runs from tens of thousands to several million dollars. The math has never made sense.
What we provide on every Ottawa project
At Dream Touch we attach the full insurance and WSIB package to the front of every contract. The general contractor clearance, the COI with the homeowner named as additional insured, and the WSIB clearance for any sub used on the project. The package is dated within 30 days of project start. We rerun verification quarterly on long projects.
This is the bare minimum any Ottawa renovation should clear. If you want help walking through a competing contractor's documentation before you sign, we'll do it for free. Email us a copy of their certificate package and we'll tell you what's missing in 24 hours. The same process is part of our standard estimating workflow, and it's free for any homeowner considering a major renovation in Ottawa.
