Picking the wrong renovation contractor is one of the most expensive mistakes a Toronto homeowner can make. We’ve all heard the horror stories — projects that stall mid-way, budgets that balloon by 40%, and “licensed” contractors who vanish before the final inspection. The GTA renovation market is busy, and not every company competing for your business deserves it.
This guide gives you a practical, 10-point checklist for vetting any renovation contractor in Toronto — and explains exactly what to look for, what to ask, and which red flags to walk away from. We’ll also be upfront: we built this checklist around the standards that David Reno holds itself to. Every point on this list is something we can demonstrate before you sign anything.
At David Reno, we’ve completed over 300 renovation projects across Toronto and the GTA — basements, bathrooms, kitchens, and open-concept conversions. We believe a homeowner who knows what to look for will always choose a better contractor. We’re confident that contractor will be us.
Why Choosing the Right Contractor Matters More Than Choosing the Right Materials
Most Toronto homeowners spend hours choosing tile, fixtures, and paint colours — and less than 30 minutes vetting the contractor who will actually install them. That’s backwards. A skilled contractor can make mid-range materials look exceptional. An unskilled or unscrupulous one can ruin the most expensive finishes in the world.
The renovation industry in Ontario has no single licensing body that covers all contractors — which means the barrier to calling yourself a “renovation company” is extremely low. That’s not meant to alarm you; it’s meant to make you a more informed buyer. The checklist below separates the professionals from the opportunists.
The 10-Point Contractor Checklist for Toronto Homeowners
✅ 1. Ontario Business Registration + Liability Insurance
Any legitimate renovation contractor operating in Toronto should be a registered Ontario business — not a sole operator working under a personal name with no paper trail. Ask to see their business registration number, and verify it through the Ontario Business Registry at ontario.ca/businessregistry.
Equally important: general liability insurance (minimum $2 million is the Toronto industry standard). This protects you if a contractor accidentally damages your home, a neighbouring property, or causes injury on site. A contractor without liability insurance means you absorb that risk. Always ask for a certificate of insurance — not just their word.
✅ 2. WSIB Clearance Certificate
The Workplace Safety and Insurance Board (WSIB) is Ontario’s workers’ compensation system. If a contractor’s worker is injured on your property and that contractor doesn’t have active WSIB coverage, you — as the homeowner — could potentially be held liable for medical and rehabilitation costs.
Request a WSIB Clearance Certificate dated within the last 30 days. You can verify clearance directly at wsib.ca using the contractor’s business name or account number. This takes less than two minutes and eliminates a major legal exposure.
✅ 3. Verifiable Toronto Portfolio (Not Just Photos)
Photos on a website or Instagram are a starting point — not proof. Anyone can pull renovation images from the internet. What you need is a verifiable local portfolio: projects completed in Toronto or the GTA, with addresses or neighbourhoods you can reference, and ideally with homeowners willing to speak to you directly.
Ask for three completed projects similar to yours in scope and neighbourhood. A basement renovation in Scarborough, a bathroom in North York, a kitchen in Etobicoke — your project isn’t abstract, and neither should their experience be.
✅ 4. Detailed Written Quote — Fixed Price, Not Estimate
There is a significant difference between a quote and an estimate. An estimate is a rough ballpark. A quote is a contractual commitment. Any contractor who gives you a number verbally — or provides a one-page “estimate” without line items — is leaving themselves room to add costs later.
Your written quote should clearly break down: scope of work, materials specified by brand and grade, labour costs, permit fees, payment schedule, start date, and projected completion date. If any of these are missing, ask for them. A contractor who won’t provide a fully itemized quote is a contractor you don’t want inside your home.
✅ 5. Permit Management (They Pull the Permits — Not You)
Under the Ontario Building Code, permits are required for structural changes, plumbing relocations, new electrical circuits, and several other common renovation scopes. Some contractors skip permits to save time. Some ask you to pull the permits yourself. Both approaches expose you to serious risk.
Unpermitted work can void your homeowner’s insurance, create problems at resale (buyers’ lawyers check permit histories), and result in orders to tear out and redo completed work. Your contractor should handle all City of Toronto permit applications and inspections as a standard part of their service — not an add-on.
✅ 6. Trade Licensing for Plumbing and Electrical
In Ontario, plumbing and electrical work must be performed by licensed tradespeople. Plumbers must hold a Certificate of Qualification from the Ontario College of Trades. Electricians must be licensed under the Electrical Safety Authority (ESA) and pull ESA permits for electrical work.
Ask your contractor directly: “Who performs your plumbing and electrical work, and are they licensed?” If they give a vague answer — or tell you it’s “just minor work” that doesn’t need a licensed trade — that’s a serious red flag. Unlicensed plumbing and electrical is not only dangerous; it invalidates any warranty and creates legal exposure for you as the homeowner.
✅ 7. A Clear Payment Schedule (Not 50% Upfront)
Payment terms tell you a lot about a contractor’s financial stability — and their confidence in their own work. A reputable contractor doesn’t need a large deposit to begin, because they have the cash flow to purchase materials and pay their trades without relying on your advance payment.
Industry standard for Toronto renovation projects: a deposit of 10–20% to confirm the booking, with subsequent payments tied to verified project milestones (demo complete, rough-ins done, tile complete, etc.). A contractor who asks for 40–50% upfront before work begins is a major warning sign. Never pay cash without a receipt, and never make the final payment until all work is completed and inspected to your satisfaction.
✅ 8. Verified Google and HomeStars Reviews
In 2026, a renovation contractor without a significant body of verified online reviews should raise questions. Look for consistent patterns — not just star ratings. Read the written reviews for mentions of: timeline adherence, communication during the project, how problems were handled, and whether the final result matched the quoted scope.
Be skeptical of contractors whose reviews are overwhelmingly generic (“Great work! Highly recommend!”) or whose review history shows a sudden spike with no long-term track record. Check Google Reviews and HomeStars — both platforms make it harder to fabricate verified reviews than a contractor’s own website testimonials.
✅ 9. A Written Warranty on Labour
Materials come with manufacturer warranties. Labour does not — unless your contractor provides one in writing. What happens if tile grout cracks six months after completion? What if a caulked shower seam fails after the first winter? What if a finished basement wall shows moisture issues a year later?
A contractor who stands behind their work offers a written labour warranty — typically one to two years minimum for Toronto renovations. This is a key differentiator between professional renovation companies and cash-job operators. Ask for the warranty terms in writing before signing any contract.
✅ 10. Dedicated Project Communication
One of the most common complaints Toronto homeowners have about renovation contractors isn’t the work itself — it’s the silence. Contractors who are difficult to reach, who don’t provide progress updates, or who leave homeowners wondering what’s happening in their own home create enormous stress.
Before signing, ask: “Who is my single point of contact during the project?” You should have one named person — a project manager or site lead — who is reachable during business hours and provides regular updates. Weekly check-ins, photos of progress, and advance notice of any delays should be standard — not something you have to fight for.
Red Flags: Walk Away If You See These
A contractor who offers a lower price in exchange for cash payment is admitting they won’t be declaring income, won’t have documented insurance coverage, and won’t be accountable if something goes wrong. You have zero legal recourse without a paper trail.
Unless they can cite the specific Ontario Building Code section that exempts your project, this phrase almost always means they’re trying to save themselves time at your legal and financial expense.
A reputable contractor with a full schedule doesn’t need to pressure you into signing today. Artificial urgency (“I have another client who wants this slot”) is a classic manipulation tactic. Take the time you need.
Three quotes come in at $28,000–$32,000 for a full bathroom renovation, and one comes in at $14,000. That lowest bid isn’t a deal — it’s a sign that something is being excluded: waterproofing, permits, proper finishing, licensed trades, or all of the above. Low bids become expensive projects.
If a contractor can’t provide a registered Ontario business address and a verifiable business registration number, there is no accountability if the project goes sideways. PO boxes and personal cell numbers are not sufficient.

Frequently Asked Questions
How do I verify a contractor’s license in Ontario?
Ontario does not have a single “contractor license” — but you can verify the credentials that matter. Check business registration at ontario.ca/businessregistry. Verify WSIB coverage at wsib.ca. Confirm licensed trades through the Ontario College of Trades for plumbers and the Electrical Safety Authority for electricians. For City of Toronto building permits, the permit holder’s information is publicly searchable at toronto.ca/buildingpermits. A fully above-board contractor will have no issue with you verifying any of this — David Reno encourages every homeowner to do so.
How many quotes should I get before hiring a renovation contractor in Toronto?
Three quotes is the standard advice — and it’s good advice, but only if you’re comparing apples to apples. Make sure each contractor quotes on exactly the same scope of work, the same material specifications, and includes permit fees. A quote that excludes permits, uses lower-grade materials, or omits certain scopes of work will always appear cheaper. The goal isn’t to find the lowest number — it’s to find the best value among contractors who are quoting the same project.
What questions should I ask a Toronto renovation contractor before hiring?
The five most important questions are: (1) Can you provide a current WSIB clearance certificate and certificate of liability insurance? (2) Who handles permits — you or me? (3) Is this a fixed-price quote, and are there circumstances where additional costs could arise? (4) Who is my dedicated contact during the project, and how will you communicate progress? (5) What is your labour warranty, and can I see it in writing? A contractor who answers all five confidently and in writing is a contractor worth serious consideration.
Is it normal for a Toronto renovation contractor to ask for a large deposit?
A deposit of 10–20% is reasonable and standard — it confirms your booking and allows the contractor to place material orders. A request for 40–50% or more before any work begins is not standard and should raise concern. Established contractors with healthy cash flow and supplier relationships don’t need to finance their operations from client deposits. Always tie payments to verified milestones, not to calendar dates.
Why is the cheapest renovation quote usually a bad sign?
In the Toronto renovation market, a quote that is significantly below the competition almost always means something has been excluded — permits, waterproofing, proper subfloor preparation, licensed trades, or adequate allowances for materials. These aren’t savings; they’re costs that will reappear later as “extras,” often at the worst possible moment in the project. Budget surprises and incomplete work are the most common outcomes from very low bids. A fixed-price quote from a reputable contractor that is competitive — not the cheapest — is usually the best protection for your budget.
