Protect Your Ottawa Home: Verify COI, WSIB, and Call Your Insurer
Before any contractor sets foot in your Ottawa home, ask for a certificate of insurance showing Commercial General Liability coverage with limits and dates, plus proof of WSIB compliance, and call your own home insurer to let them know work is starting. Those three things, verified documents and a quick phone call, cover most of what protects your home, your wallet, and your legal standing if something goes wrong.
TL;DR:
Homeowners should verify that contractors have active Commercial General Liability insurance with sufficient limits and correct policy dates before starting work.
A builder’s risk policy may be necessary to cover damages to materials and the structure during construction, and homeowners should confirm if the contractor arranges this coverage.
Checking the accuracy and validity of the certificate of insurance involves calling the insurer directly to verify policy status, limits, and subcontractor coverage, not just trusting the document.
A written contract should explicitly reference the contractor’s insurance details and include warranties, with all documentation kept organized for potential claims.
Signaling warning signs such as cash-only payments, missing paperwork, or vague insurance answers indicates unlicensed or uninsured work, requiring immediate insurer notification if damage occurs.

1. Which insurance documents to ask for and what each proves
A certificate of insurance, or COI, is a formal document issued by an insurer that proves a contractor’s coverage actually exists. It is a document issued by an insurer, and it should name specific numbers you can check.
When a contractor hands you one, look for these fields before you look at anything else:
Insurer name and policy number, so you can call the insurance company directly rather than trust a logo.
Policy type, confirming it is Commercial General Liability (CGL), not just auto or property coverage.
Per-occurrence and aggregate limits, which cap how much the policy pays for a single incident and across the whole policy term.
Effective and expiry dates, so you know coverage is active during your project, not expired last month.
Certificate holder, which should list you or your address if you request it.
CGL insurance typically covers third-party bodily injury and property damage caused during the work, which matters if a contractor’s crew damages your flooring or a worker gets hurt on your property. The limits matter because a policy with a coverage cap that may be insufficient for serious injury claims or extensive water damage may not cover a serious injury claim or extensive water damage, so higher limits generally mean more protection for you.
Workers’ compensation proof, called WSIB clearance in Ontario, shows that injured workers get paid through the insurance system rather than suing you directly. Government guidance recommends verifying workers’ compensation and liability coverage before signing anything, since an uninsured worker injured on your property can become your financial problem instead of the contractor’s.
Ask about automobile liability for company vehicles parked in your driveway, and request separate COIs for any subcontractors who will be on site, since a general contractor’s policy does not automatically extend to the people they hire.
2. Homeowner insurance gaps and when to arrange builder’s risk
Your contractor’s CGL policy protects against injuries and damage they cause to other people or property. It usually does not protect the renovation itself, meaning if a fire, storm, or theft damages materials or your half-finished kitchen, that loss can fall into a gap between your home policy and the contractor’s coverage.
Builder’s risk insurance, also called course-of-construction coverage, fills that gap by covering the structure and materials during the build. The Insurance Bureau of Canada recommends homeowners notify their insurer before renovations begin, since standard home policies may exclude damage tied to construction activity. Builder’s risk policies still exclude certain things, most commonly faulty workmanship and damage linked to a vacant property during a long renovation.
Three steps protect you here:
Call your home insurer before work starts, not after.
Ask for written confirmation of what your current policy covers during the project.
Ask the contractor directly whether they arrange builder’s risk coverage or expect you to.
3. How to verify a certificate of insurance quickly: a homeowner’s checklist (see our detailed guide on how to review roofing contractor insurance certificates for practical tips)
A COI is only useful if it is real and current. Verifying one takes ten minutes and a phone call, and it is worth doing every time, even for a contractor a neighbor recommended.
Find the insurer’s published phone number yourself. Search for it independently rather than dialing the number printed on the certificate, since a fabricated COI would list a fabricated number too.
Confirm the policy is active. Ask the insurer to verify the policy number, type, and that it has not lapsed or been canceled.
Check the limits and dates. Make sure the per-occurrence and aggregate limits match what the contractor told you, and that the effective and expiry dates cover your entire project timeline.
Ask about additional insured status. Industry advice suggests requesting to be added as an additional insured on the contractor’s policy, which gives you a more direct path to a claim if their work damages your property.
Confirm cancellation notice terms. Ask whether the insurer notifies certificate holders if the policy is canceled mid-project.
Ask about subcontractor coverage. Confirm subs are covered under the main policy or request their own COIs separately.
Pro Tip: Keep a copy of every COI you verify in the same folder as your signed contract, since you may need both if a dispute or claim comes up months later.
4. Screening questions and contract checklist to require before work starts
Verbal assurances are not documentation. Before you sign anything, ask directly: Are you insured? Can I see a current COI right now? Are your workers covered under WSIB? Who are your subcontractors, and are they insured too?
A written contract should lock in what those answers promised. Require it to include:
The full scope of work, schedule, and payment terms, broken into stages rather than one lump sum.
The contractor’s COI referenced by policy number and date, attached as an exhibit.
Written warranty terms covering workmanship, separate from the insurance documents.
A clause requiring the contractor to provide an updated COI if their coverage changes mid-project.
Our communication checklist for Ottawa renovations walks through how to keep these conversations organized from the first quote onward. Once signed, keep the contract and every COI together in one file, and take dated photos of the work area before, during, and after, since photos become evidence if you ever need to file a claim.
5. Red flags and immediate steps if you discover missing or invalid coverage
Some warning signs show up before you even sign a contract. Watch for:
A contractor who insists on cash payment only, with no receipts.
Refusal or repeated delay in providing a written COI or signed contract.
Vague or evasive answers about WSIB coverage for their crew.
No clear answer about whether subcontractors carry their own insurance.
Cash-only deals and missing paperwork often point to unregistered, uninsured work, and government consumer guidance warns that this removes your warranty protection and legal recourse entirely.
If damage or an injury happens mid-project, notify your own insurer immediately, document the damage with photos, and collect medical or repair receipts.
6. Ottawa perspective: how a trustworthy local contractor documents insurance and warranty
We think of a certificate of insurance and a written warranty as two separate promises that should both show up in writing before work begins. One covers liability and property damage. The other covers the quality of the finish itself.
As a cabinet painting specialist working across Ottawa, we reference insurance and warranty details directly in our written quotes, so homeowners never have to chase down documentation after the fact. We back our work with a warranty, an example of the kind of workmanship guarantee worth asking any contractor for, alongside their COI. Our warranty guide for Ottawa homeowners explains why that distinction between insurance and warranty matters when you are comparing quotes.

FAQ
What is a certificate of insurance and why does a contractor need one?
A certificate of insurance is a document from an insurer confirming a contractor carries active coverage, typically Commercial General Liability. It lists policy limits, dates, and the insurer’s contact information, letting you verify the coverage is real before work starts.
How do I know if a contractor’s WSIB coverage is valid?
Ask the contractor for their WSIB clearance status and confirm it directly with WSIB rather than taking their word for it. This matters because government guidance recommends verifying workers’ compensation coverage before a contract is signed, since uncovered worker injuries can become your liability.
Does my home insurance cover renovation work?
Not automatically. Standard home policies often have gaps around construction activity, which is why insurers recommend notifying them before a renovation begins and asking whether a separate builder’s risk policy makes sense for your project.
What should I do if my contractor refuses to provide a COI?
Treat it as a serious warning sign and ask for alternative proof before proceeding, such as direct confirmation from their insurer. If they still refuse, consider it grounds to walk away, since a legitimate, insured contractor has no reason to withhold that document.
What is the difference between a contractor’s insurance and a homeowner’s warranty?
Insurance covers liability for injury or property damage during the project, while a warranty covers the quality and durability of the finished work afterward. Request both in writing, since one does not substitute for the other.
