How do I verify that a Toronto drywall contractor has proper WSIB coverage and liability insurance?

Verifying WSIB coverage and liability insurance before hiring a drywall contractor is one of the most important steps you can take to protect yourself as a GTA homeowner. Without proper coverage, you could be held personally liable if a worker is injured on your property — and drywall installation involves real physical risks including falls from scaffolding, repetitive strain injuries, and dust inhalation.

WSIB (Workplace Safety and Insurance Board) coverage is mandatory in Ontario for construction businesses with employees. Independent operators may be exempt, but many carry optional coverage regardless. To verify a contractor's WSIB status, visit the WSIB website at wsib.ca and use the "Confirm Independent Operator Status" or "Clearance Certificate" tools. You can also call WSIB directly at 1-800-387-0750. Ask the contractor for their WSIB account number and a current clearance certificate — this document confirms they are registered, in good standing, and have paid their premiums. A valid clearance certificate is date-stamped and should be current. If a contractor cannot produce one, that is a significant red flag.

The reason this matters so much is Ontario's constructive employer liability. If an uninsured worker is injured on your residential property, WSIB can deem you the "constructor" or employer and hold you responsible for the worker's claim costs. This can amount to tens of thousands of dollars for a serious injury. A $5,000 drywall job is not worth that kind of exposure.

Liability insurance is separate from WSIB and covers property damage — for example, if a drywall crew accidentally damages your hardwood floors, puts a stilts mark through your ceiling, or breaks a window while carrying sheets into the house. A reputable GTA drywall contractor should carry a minimum of $2 million in commercial general liability (CGL) insurance. Many larger GTA firms carry $5 million. Ask for a certificate of insurance naming you as the certificate holder, and verify the policy is current by calling the insurance company directly. This certificate should show the policy number, coverage limits, and expiry date.

For condo renovations in Toronto, most property management companies and condo boards require proof of both WSIB and $2-5 million liability insurance before granting contractor access to the building. This is actually a helpful safeguard — if your contractor cannot satisfy the condo board's insurance requirements, that tells you something about their professionalism.

What to Ask and What to Watch For

Request these documents before any work begins and before signing a contract: a current WSIB clearance certificate, a certificate of insurance showing CGL coverage of at least $2 million, and their HST number (a legitimate business will be HST-registered if their annual revenue exceeds $30,000). Keep copies of all documents with your project file.

Be cautious of contractors who say they "don't need" WSIB because they work alone. While some sole proprietors are genuinely exempt from mandatory WSIB registration, many use this as an excuse to avoid the cost. An independent operator who carries voluntary WSIB coverage is demonstrating a level of professionalism and responsibility that benefits you.

The cost of proper insurance is built into a professional contractor's pricing. In the GTA, expect to pay $2.50-$4.00 per square foot for standard wall hanging from a properly insured contractor. If someone quotes you significantly less, ask yourself whether they are cutting corners on insurance, WSIB, or HST — all of which transfer risk directly to you.

One practical tip: do not accept photocopies of insurance documents without verifying them independently. Unfortunately, fraudulent certificates do circulate. A quick phone call to the insurance company costs nothing and gives you certainty. Toronto Drywall Installers can help match you with drywall professionals through the Toronto Construction Network, but we always recommend homeowners independently verify insurance and WSIB status before signing any contract.
