How to hire a renovation contractor pro in Canada
- Check the licensing rule for your province: Quebec requires an RBQ licence for contractors, Toronto requires a municipal Building Renovator licence, and BC licenses residential builders for new-home work — rules are provincial and municipal, not federal
- Ask for a WSIB (Ontario) or WorkSafe clearance certificate so an injured worker can't claim against you
- Verify general liability insurance of at least $2 million
- Confirm who applies for the municipal building permit — required for structural, plumbing rough-in, and most electrical changes
- Get three itemized quotes after site visits and compare line by line
- Apply the statutory holdback from your provincial lien act (10% in Ontario) to progress payments until the lien period expires
Contractor regulation in Canada is provincial and municipal: Quebec's RBQ licence is mandatory for most contracting, while Ontario and other provinces regulate through municipal licensing and permits. Provincial construction lien acts let unpaid subcontractors lien your home, which is why the statutory holdback (e.g., 10% in Ontario) exists and should be used on any significant renovation.

Frequently asked questions
How many renovation quotes should I get in Ottawa South?
Get at least three itemized quotes from contractors who have visited the property in Ottawa South. Phone or photo-based estimates are fine for a ballpark, but only an in-person survey produces a quote a contractor will stand behind. Discard any quote that is dramatically below the others rather than celebrating it — it usually signals missed scope or planned extras later.
How much deposit is normal for a renovation?
For most markets 10% or less of the contract value is a reasonable deposit, sometimes up to 20-30% for jobs with heavy upfront material orders like custom cabinetry. Several countries cap deposits by law. Never pay a large share of the total before work starts, and never pay the full amount up front.
Do I need permits for my renovation in Ottawa South?
Cosmetic work (painting, flooring, replacing fixtures in place) rarely needs a permit. Structural changes, wall removals, and significant plumbing or electrical alterations usually do, and rules in Ottawa South follow your national and local building codes. Ask the contractor to name the specific approval needed and who applies for it — a contractor who suggests skipping permits is transferring the legal risk to you.
What are variations (change orders) and how do I keep them under control?
A variation is any change to the agreed scope after signing — moving a wall, upgrading tiles, fixing a hidden problem. Insist every variation is priced and approved in writing before the work happens. Most renovation budget blowouts are not the original quote being wrong; they are dozens of verbally-approved variations nobody tracked.
What can I do if the work is defective or the contractor disappears?
Document defects in writing with photos, give the contractor a written chance to fix them within a set period, and withhold only the retention amount — not all payment — while they do. If they abandon the job, your remedies are your contract, any licensing body's complaint process, consumer protection agencies, and small claims court. This is why the paper trail and staged payments matter from day one.
Should I hire a general contractor or manage the trades myself?
Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.
What do general contractors charge in Canada?
Hourly rates typically run CAD 50-130 depending on province and city, with most renovations priced as a project including a 10-20% management markup. Mid-range whole-home renovation work commonly lands around CAD 100-300 per square foot in major metros.
Do I need a permit for interior renovations in Canada?
Cosmetic work doesn't need one, but municipal building permits are required for structural changes, moving plumbing, most electrical alterations (with inspection by the provincial electrical authority, e.g., ESA in Ontario), and basement legalizations. Unpermitted work commonly surfaces during home inspection at resale and can kill a deal.
