How to Avoid Hiring a Fraudulent Contractor in Montreal: Red Flags, Licence Checks & a Safe Hiring Checklist
Hiring a renovation contractor is one of the largest financial decisions a Montreal homeowner makes. In a city experiencing a sustained renovation boom, the demand for skilled tradespeople has never been higher — and unfortunately, so has the number of complaints filed against contractors who take deposits and disappear, leave work unfinished, or produce results far below what was promised. According to the Régie du bâtiment du Québec (RBQ), thousands of complaints are filed each year against contractors operating without a valid licence or with a history of disputed work. The consequences for homeowners range from costly repairs and delayed projects to lengthy legal battles. This guide will show you exactly how to protect yourself: what warning signs to look for before you sign anything, how to verify a contractor's licence in Quebec in under two minutes, and what your written contract must include to give you real legal protection.Important reminder
In Quebec, it is illegal to perform most construction and renovation work without a valid RBQ licence. If something goes wrong with an unlicensed contractor, you may have limited legal recourse.
The 7 Warning Signs of an Untrustworthy Contractor
Most homeowner horror stories share common starting points. Before any money changes hands, watch closely for these red flags:
1
Unusually large upfront deposit requested in cashA legitimate contractor in Quebec typically requests a deposit of 10%–20% of the project total, tied to a clear payment schedule. Demands for 50% or more upfront — particularly in cash — are a serious warning sign. Cash payments remove your paper trail and legal recourse.
2
No written contract — or a vague oneIf a contractor asks you to agree to work verbally, or provides a one-paragraph quote with no itemized breakdown, no start and end dates, and no payment milestones, you have no legal basis to hold them accountable if things go wrong.
3
Cannot provide an RBQ licence numberAny contractor performing renovation, electrical, or plumbing work in Quebec must hold a valid licence from the Régie du bâtiment du Québec. If they hesitate, deflect, or claim the licence is "in process," stop the conversation and move on.
4
No verifiable physical address or business registrationAn established renovation company has a verifiable address, a registered business number (NEQ) in Quebec, and a consistent online presence. Contractors who operate only via a mobile number and a social media page with no history are far harder to pursue if problems arise.
5
No proof of insuranceAt minimum, a licensed contractor should carry general liability insurance of at least $2 million. Without it, if a worker is injured on your property or your home is damaged during work, you could be held liable. Always ask for a current certificate of insurance — and verify it is active.
6
Vague or shifting timelinesProfessional contractors give you a realistic schedule tied to specific project phases. "We'll be done in a few weeks" is not a timeline. If estimated start dates keep shifting before work even begins, that pattern rarely improves once a deposit is paid.
7
Reluctant to provide references or past project photosAn experienced contractor who takes pride in their work will readily provide references from past clients and photos of completed projects. Reluctance or vague excuses ("clients prefer privacy") is a red flag, not a reason to proceed.
How to Verify a Contractor's RBQ Licence in Quebec (Step-by-Step)
Verifying a contractor's RBQ licence takes less than two minutes and costs nothing. Here's exactly how to do it:- Visit the official RBQ licence registry at rbq.gouv.qc.ca — this is the only authoritative source. Third-party directories are not verified.
- Enter the contractor's name or licence number as it appears on their quote or business card.
- Confirm the licence is active and covers your type of project. RBQ licences are categorized by trade — a contractor licensed for general renovation is not automatically licensed for electrical work.
- Check for complaints or restrictions. The registry will display any active complaints, past licence suspensions, or restrictions on the licence holder's account.
- Keep a screenshot of the verification result for your records, timestamped with today's date.
Pro tip
If you are also hiring a separate subcontractor for plumbing or electrical work, verify their licence independently. The general contractor's licence does not cover subcontractors' work automatically.
What a Legitimate Renovation Contract in Quebec Must Include
A verbal agreement — or even a short email — is not a contract. To be legally enforceable and to give you real protection as a homeowner, your written renovation contract should include all of the following:- Full legal name and address of the contractor, including their RBQ licence number
- Detailed scope of work — exactly what will be done, and equally important, what is explicitly excluded
- Itemized materials list with specified brands and grades, or a written acknowledgment that the contractor has discretion within an agreed budget
- Project start and completion dates — specific dates, not "approximately 6 weeks"
- Payment schedule tied to milestones — for example, 20% on signing, 30% at framing completion, 30% at finishing, 20% at final inspection
- Permit responsibilities — who pulls the required permits, and whose cost they fall under
- Warranty provisions — what defects are covered, for how long, and what the process is for claiming warranty work
- Change order process — how any additions or modifications to the original scope will be priced and approved in writing before work begins
- Dispute resolution clause — what process applies if disagreements arise (mediation, arbitration, or court)
10 Questions to Ask Before You Sign Anything
Use this list during your initial consultation. A professional contractor will answer all of these directly and without hesitation:- What is your RBQ licence number, and can I verify it today?
- Can I see a current certificate of insurance for liability and workers' compensation?
- Who will be on site daily — you personally, or subcontractors?
- Will you pull all required building permits, and are those costs included in your quote?
- Can you provide three recent client references I can contact directly?
- What is your payment schedule, and do you accept cheque or bank transfer?
- What happens if the project runs over the quoted cost — how are change orders handled?
- What is your warranty on workmanship, and how do I claim it if needed?
- Have you completed projects similar to mine in this area? Can I see photos?
- Are there any parts of this project you would subcontract, and if so, to whom?

What to Do If You Have Already Been Victimized by a Contractor
If a contractor has taken your deposit, abandoned your project, or produced seriously deficient work, you are not without options. Here are the steps to take:- Send a formal written notice. Email or registered mail the contractor specifying exactly what remains incomplete or deficient, and give them a reasonable deadline (typically 10–15 business days) to remedy the situation. Keep all correspondence.
- File a complaint with the RBQ. Visit rbq.gouv.qc.ca and file a formal complaint. The RBQ investigates complaints against licensed contractors and can impose sanctions, suspend licences, or compel corrective action.
- Contact the Office de la protection du consommateur (OPC) if the contractor's work was subject to the Consumer Protection Act (which covers most residential renovation contracts).
- Use Small Claims Court for amounts up to $15,000. The process is designed to be accessible without a lawyer. Document everything: photos, written estimates, contracts, bank transfers, and text messages.
- Consult a construction law attorney for larger claims or complex situations involving permit violations, structural issues, or amounts exceeding the small claims limit.
The most important thing is to act quickly and to avoid paying any additional amounts to the contractor while a dispute is in progress.
