What are Toronto's requirements for WSIB coverage when hiring a bathroom renovation contractor?

In Ontario, the Workplace Safety and Insurance Board (WSIB) provides workplace injury insurance, and homeowners should verify that their bathroom renovation contractor carries active WSIB coverage before any work begins. While the legal requirements around WSIB for residential renovation contractors have some nuance, the practical recommendation is clear: always hire contractors with WSIB coverage to protect yourself from liability.

Under Ontario's Workplace Safety and Insurance Act, construction is a mandatory coverage industry — meaning construction businesses with employees are required to register with WSIB and maintain active coverage. This includes bathroom renovation contractors, plumbers, electricians, tile installers, and other trades working on your GTA bathroom project. Independent operators (sole proprietors with no employees) may not be legally required to carry WSIB but can opt for voluntary Independent Operator coverage.

Here is why this matters to you as a homeowner: if a worker is injured on your property and the contractor does not have WSIB coverage, you as the homeowner could be held liable for the worker's medical costs, lost wages, and rehabilitation expenses. This is not a theoretical risk — construction work involves power tools, heavy materials, scaffolding, and the physical demands of demolition and installation. Bathroom renovations specifically involve working in confined spaces, lifting heavy tubs and tile, and using sharp cutting tools.

How to Verify WSIB Coverage

Before signing a contract, ask your contractor for their WSIB Clearance Certificate. This document confirms that the contractor is registered with WSIB and that their account is in good standing — meaning their premiums are paid and their coverage is active. You can also verify a contractor's WSIB status independently through the WSIB website at wsib.ca using their online clearance certificate tool. You will need the contractor's legal business name or WSIB account number.

A valid clearance certificate should be current — they have an expiry date, so check that the certificate covers the period during which your bathroom renovation will take place. For longer projects, you may want to request an updated certificate partway through.

What About Subcontractors?

Bathroom renovations typically involve multiple trades — a general contractor managing the project, plus subcontractors for plumbing, electrical, tile, and possibly drywall and painting. Each subcontractor should carry their own WSIB coverage. Ask your general contractor whether their subcontractors are WSIB-registered and request clearance certificates for each trade that will be working in your home. A professional GTA bathroom contractor will have this documentation readily available and will not be offended by the request.

WSIB Plus Liability Insurance

WSIB coverage and general liability insurance are two separate things, and you want your contractor to carry both. WSIB covers worker injuries. General liability insurance covers damage to your property — if a plumber accidentally floods your basement, if a tile saw damages your hardwood floor, or if demolition causes unintended structural damage. A reputable Toronto bathroom contractor will carry a minimum of $2 million in general liability insurance along with active WSIB coverage.

Ask for proof of both before work begins, and keep copies in your project file. If a contractor hesitates or refuses to provide WSIB clearance and proof of insurance, that is a significant red flag. In a market as active as the GTA, there is no shortage of professional, properly insured bathroom renovation contractors — do not settle for one who cannot provide basic documentation.
