Does WSIB coverage matter when hiring a stucco contractor in Ottawa?

WSIB coverage doesn't just matter — it's a legal requirement in Ontario's construction industry, and ignoring it when hiring a stucco contractor can have serious financial consequences for you as the homeowner.

Why WSIB Is Non-Negotiable for Ottawa Stucco Projects

The Workplace Safety and Insurance Act classifies construction as a compulsory coverage industry in Ontario. Every stucco contractor with employees — and independent operators performing construction work — must maintain active WSIB registration and pay premiums. There's no opt-out, no exception for small jobs, and no workaround.

Here's why this directly affects you as the property owner:

Homeowner liability exposure: Under Ontario's WSIA, if an unregistered contractor or their worker is injured on your property, WSIB can assess the costs against you as the "deemed employer." Stucco work is inherently physical — workers are on scaffolding at heights, mixing heavy materials, working with power tools in Ottawa's variable weather. A fall from scaffolding during a second-storey stucco application could result in claims exceeding $100,000 in medical and lost-wage costs. Without WSIB coverage, that liability can land on your doorstep.

How to verify WSIB status:

• Visit wsib.ca and search under "Clearance Certificate" using the contractor's business name or WSIB account number.- Request a current clearance certificate — it should show "Account in good standing" and be dated within the last 60 days.- Verify it before signing any contract and again before releasing final payment on longer projects.

What a valid clearance certificate confirms:

• The contractor is registered with WSIB.- Their premium payments are current (no arrears).- Workers are covered if injured on your job site.- You are protected from "deemed employer" liability.

Common situations Ottawa homeowners encounter:

• "I'm a sole proprietor, I don't need WSIB" — Partially true for independent operators with no employees, but only if they've applied for and received an independent operator exemption. Many stucco jobs require helpers, and if they bring anyone on site, coverage is mandatory. Ask for documentation either way.- "My liability insurance covers it" — CGL insurance and WSIB serve completely different purposes. CGL covers property damage; WSIB covers worker injury. You need both.- Subcontractors on site — If your general contractor uses stucco subcontractors, each sub needs their own WSIB clearance. The GC's coverage doesn't automatically extend to subs.

In Ottawa, stucco projects typically cost $10–$16 per square foot for quality work. WSIB premiums for construction trades run roughly $2.50–$3.50 per $100 of payroll — a modest cost that legitimate contractors build into their pricing. A quote that's dramatically cheaper may indicate a contractor skipping WSIB, which shifts the risk onto you. Always verify before work begins.
