How to Verify an Eavestrough Contractor Is Insured in Ontario

Verifying an eavestrough contractor's insurance and workplace safety coverage in Ontario is straightforward, and taking these steps before any work begins protects you from serious financial liability.

The most important verification is WSIB (Workplace Safety and Insurance Board) coverage. Eavestrough installation involves working at heights on ladders and scaffolding, handling sharp sheet metal, and operating roll-forming machinery — all activities with real injury risk. Under Ontario law, if an uninsured contractor or their employee is injured on your property, you as the homeowner could be held liable for medical costs and lost wages. Ask the contractor for their WSIB account number, then verify their status directly through the WSIB online clearance certificate system at wsib.ca. You can request an independent clearance certificate that confirms their account is active and in good standing. This takes about two minutes and costs nothing.

Insurance and Business Verification Steps

Beyond WSIB, confirm the contractor carries commercial general liability insurance with a minimum of $2 million in coverage. This protects your property if the contractor damages your roof, siding, landscaping, or home exterior during installation. Ask for a copy of their insurance certificate and verify it is current — policies can lapse, and a certificate from last year may no longer be valid. You can call the insurance company listed on the certificate to confirm active coverage.

Unlike electrical or plumbing work, eavestrough installation in Ontario does not require a specific trade licence. There is no provincial eavestrough licence or certification that contractors must hold. This means anyone can legally offer eavestrough services, which makes your own due diligence even more important. However, if your eavestrough project includes hardwired heat cable installation for ice dam prevention, that portion of the work must be performed by an ESA (Electrical Safety Authority) licensed electrician. You can verify an electrician's licence through the ESA's online contractor search tool.

Check whether the contractor has a registered business in Ontario. You can search the Ontario Business Registry to confirm they are a legitimate registered business rather than someone operating informally. While not legally required for all sole proprietors, formal business registration suggests a higher level of professionalism and accountability.

For an additional layer of confidence, check the contractor's record with the Better Business Bureau and search for any complaints filed with the Ontario Ministry of Public and Business Service Delivery. Online reviews on Google are useful but should be weighed carefully — look for patterns across many reviews rather than reacting to a single positive or negative comment.

The entire verification process takes less than 30 minutes and can save you from thousands of dollars in liability. Any contractor who hesitates to provide WSIB clearance or insurance documentation is not worth your consideration.
