The single biggest mistake Ottawa homeowners make isn’t choosing the wrong tile or the wrong cabinet colour: it’s choosing the wrong contractor. A bad renovation experience costs more to fix than it would have cost to do it right the first time. These 10 questions will protect your home, your budget, and your timeline before you sign anything.
Why Contractor Selection Matters More Than Anything Else
Ottawa has hundreds of renovation contractors: from licensed, experienced professionals to unlicensed handymen who take on work beyond their qualifications. The difference between them isn’t always obvious from a website or a first phone call. It becomes obvious when walls are opened, permits are missed, subcontractors don’t show up, or a project goes 40% over budget.
These 10 questions filter out the contractors who will cost you more than you save.
10 Questions Every Ottawa Homeowner Should Ask
1. Are You Licensed and Insured in Ontario?
In Ontario, general renovation contractors don’t require a provincial licence the way electricians and plumbers do. However, your contractor should carry:
- WSIB coverage (Workplace Safety and Insurance Board): required to protect you from liability if a worker is injured on your property
- General liability insurance: minimum $2 million, protects your home if damage occurs during the project
- Licensed sub-trades: all plumbers and electricians working on your project must be licensed in Ontario
What to do: Ask for a copy of their WSIB clearance certificate and certificate of insurance. A legitimate contractor will provide these without hesitation.
2. Do You Pull the Permits?
Any renovation involving structural, plumbing, or electrical work in Ottawa requires permits. Ask directly: “Do you handle the permit application, or is that on me?”
The right answer: the contractor handles permits on your behalf, includes them in the project scope, and manages the inspection schedule.
Red flag: Any contractor who says “we don’t need permits for this” when the scope clearly requires them. Skipping permits creates insurance, insurance, and resale problems that can cost tens of thousands of dollars later.
3. Can I See Recent Ottawa Projects?
Ask for photos and references from Ottawa projects completed in the last 12 to 24 months: specifically projects similar to yours. A bathroom renovation specialist should show you bathrooms. A basement contractor should show you finished basements.
What to look for: Clean tile work, consistent grout lines, properly fitted fixtures, no visible shortcuts. Ask to speak directly with 2 to 3 past clients: a confident contractor will have no issue connecting you.
4. Who Is Actually On My Job Site Every Day?
Many Ottawa contractors sell the project and then pass it to a subcontractor you’ve never met. Ask directly: “Will you or a named site supervisor be present every day work is being done?”
Owner-led contractors: where the owner or a dedicated site supervisor stays closely involved: consistently produce better results and better communication.
5. What’s Your Written Warranty?
Ontario’s Tarion warranty applies to new homes, not renovations. Your renovation warranty is only as good as the contractor’s written commitment. Ask what they warrant: and for how long.
A confident contractor will offer at minimum a 1-year labour warranty on their work. Some offer 2 to 5 years on specific scopes. Get it in writing in the contract.
6. How Do You Handle Change Orders?
Change orders: additions or modifications to the original scope: are where renovation budgets go off the rails. Ask: “What is your change order process, and how are they priced?”
The right answer: every change is documented in writing with a price before work begins. No surprises at the end of the project.
Red flag: Any contractor who says “we’ll figure it out as we go” or dismisses change order documentation.
7. What’s Your Payment Schedule?
A legitimate Ottawa contractor will have a structured payment schedule tied to project milestones: not a demand for 50% upfront.
Typical Ottawa renovation payment structure:
- 10 to 15% deposit to confirm booking and order materials
- Draw at demo / rough-in stage
- Draw at drywall / mid-point
- Final payment at completion and client sign-off
Red flag: Requests for more than 30 to 40% upfront, cash-only payment, or no written payment schedule. These are the most common patterns in renovation fraud cases.
8. Are You a GOHBA or RenoMark Member?
The Greater Ottawa Home Builders’ Association (GOHBA) and the RenoMark program are industry membership organizations that hold members to a professional code of conduct. Membership signals a contractor takes their business seriously.
Not all good contractors are members: but membership is a meaningful differentiator when comparing similar-quality contractors.
9. Can I Talk to 3 Recent Clients?
Google reviews are valuable but filtered. Asking for direct client references: and actually calling them: is one of the best ways to verify a contractor’s quality and communication style.
Questions to ask references:
- Did the project finish on time and on budget?
- How did the contractor communicate during the project?
- Were there any issues, and how were they handled?
- Would you hire them again?
10. What Happens If Something Goes Wrong After Completion?
Ask directly: “If I call you 6 months after the project is done with a warranty issue, what happens?”
The right answer: they return promptly, assess the issue, and correct any defects in their workmanship at no charge within the warranty period. Get this commitment in the written contract.
Red flag: Vague answers, reluctance to commit in writing, or suggesting you’d need to “work it out.” A contractor confident in their work doesn’t hesitate to back it.

Frequently Asked Questions
How many renovation quotes should I get in Ottawa?
Get 3 quotes, all based on the same written scope of work. This gives you a real market reference. Be wary of the lowest quote: it often means missing scope, lower-quality materials, or a contractor who will make up the difference through change orders.
How do I check if a contractor is legitimate in Ottawa?
Verify their WSIB clearance certificate at wsib.ca, check their Google Business Profile for review history and photos, ask for their business registration number, and call at least 2 client references. GOHBA and RenoMark membership can also be verified on their respective websites.
What should a renovation contract include?
A proper renovation contract should include: complete scope of work, material specifications, permit responsibility, payment schedule and milestones, change order process, warranty terms, project start and estimated completion dates, and dispute resolution process.
Is the cheapest quote usually the best value?
Almost never. The cheapest quote typically means one of: lower-quality materials, less experienced labour, missing scope items, or a contractor who will add costs through change orders. Compare quotes on equal scope and materials: then evaluate price in context.
