The kitchen is gutted, the deposit is gone, and the contractor who answered every text in the first week has stopped replying. Or the crew did finish, but the basement floods at the first heavy rain and the invoice is several thousand dollars higher than the number you agreed on. Renovation disputes are hard on people because they happen inside the home. You cannot walk away from the problem at the end of the day. You are cooking on a hot plate and looking at it.
The instinct is to do something immediately: post a warning online, hire someone else to rip it all out, or refuse to pay another cent. Each of those moves can be reasonable in the right circumstances, and each can damage your position in the wrong ones. A few calm days spent collecting evidence and reading your contract usually put you in a much stronger place than a fast reaction.
Please treat this article as general information about Ontario law. It is not legal advice about your renovation, and the right next step depends on your contract, the amount at stake, and how far the work progressed.
Your Starting Point: The Consumer Protection Act
When a homeowner hires a business to work on their home, the deal is generally a consumer agreement under Ontario’s Consumer Protection Act, 2002. That matters because the Act gives you rights the contractor cannot simply take away with fine print. Section 7 says the rights in the Act apply despite any agreement or waiver to the contrary. A replacement statute, the Consumer Protection Act, 2023, has passed but takes effect only when proclaimed, so check which version applies if you are reading this some time from now.
Several protections come up again and again in renovation files:
- Quality of the work. A supplier is deemed to warrant that services are of a reasonably acceptable quality. A clause saying “work accepted as is” does not automatically erase that protection.
- Estimates. If your agreement includes an estimate, the supplier generally cannot charge more than 10 per cent above it. A genuine change in scope that you agreed to is a different matter, which is why written change orders are so valuable.
- Written contracts. The province’s consumer guidance says renovation contracts over $50 must be in writing and that anything left out of the written contract may not be provided.
- Cooling-off rights. If you signed a renovation or repair contract in your home, Ontario’s guidance describes a 10 calendar-day period to cancel for any reason. If work has started in that window, you can still cancel, but you may owe reasonable compensation for work and materials already supplied.
A contractor who worked without any written contract has not necessarily lost the right to be paid, and you have not automatically won. A missing contract can still help you, because it strengthens the argument that the price and scope were never what the contractor now claims. It also makes the evidence you do have, such as texts and e-transfers, far more important.
Pin Down What Went Wrong
Renovation complaints tend to fall into a few categories, and the category shapes the remedy.
Abandonment. The contractor stopped showing up with the job incomplete. The central question is how much you paid compared with the value of what was actually done. You will also want proof that you gave them a fair chance to return.
Defective work. The job was completed, but badly. Tiles lift, wiring fails inspection, the new deck is out of level. Here, the cost of correcting the work is usually the main measure of your loss, and an independent opinion becomes important.
Overcharging. The final bill exceeds the estimate, or includes extras you never approved. The 10 per cent rule and your paper trail do much of the work.
Permit and code problems. Ontario’s guidance tells homeowners that they are responsible for obtaining building permits and meeting legal requirements, and that if the contractor is getting the permits, the contract should say so. Before assuming the contractor alone is exposed, call the City of Brampton’s building division and find out whether a permit exists and whether inspections were passed. An unpermitted basement apartment can leave you with a compliance problem even if the contractor caused it.
Many disputes combine two or three of these. Separating them out makes it much easier to calculate a number and to explain your claim to a lawyer, a mediator, or a judge.
Evidence Disappears Faster Than You Think
The most common regret in these disputes is having repaired the problem before documenting it. Once the bad drywall is gone, your proof is gone with it. Before anyone corrects the work:
- Photograph and video every problem area, with wide shots to show location and close-ups to show the defect.
- Get a written assessment from an independent, qualified tradesperson that describes what is wrong and what it would cost to fix.
- Export your full text and email conversations with the contractor, keeping dates and names visible.
- Gather every contract, quote, change order, invoice, and proof of payment, including e-transfer confirmations and cancelled cheques.
- Keep a dated list of when the crew attended, who was there, and what got done.
If you need urgent repairs because of water or a safety issue, go ahead and protect the house. You generally have a duty to act reasonably to limit your losses. Just capture the condition first, and keep the removed materials if that is practical. Giving the contractor written notice and a brief chance to inspect, where the situation allows it, makes it harder for them to claim later that you never gave them the opportunity.
Careful With the Last Payment: Liens and Holdback
Homeowners are often surprised to learn about construction liens. Under Ontario’s Construction Act, a contractor, subcontractor, or supplier who has not been paid may be able to register a claim for lien against your property title. A registered lien can interfere with a sale or a refinancing, and it can arrive when you thought the whole matter was a simple argument about money.
Three rules are worth understanding before you decide to withhold money:
- Holdback. Section 22 requires each payer on a contract under which a lien may arise to retain 10 per cent of the price of services or materials as they are actually supplied, until the lien period has passed. Many homeowners have never heard of this. Paying 100 per cent right away can leave you exposed to a subcontractor’s lien even after you have settled in full with the general contractor.
- Timing. A contractor’s lien generally expires if it is not preserved within 60 days of certain triggering events, such as completion or abandonment of the contract. A preserved lien must then be perfected, usually by starting an action, within a further 90-day window.
- Getting it off title. The Act provides ways to vacate a lien from title, often by paying money or posting security with the court while the dispute continues. That can free up a sale, but you should get advice before going down that road.
A lien is a claim, and it does not settle who is right. Still, a contractor with a lien has leverage, and lien cases have their own steps and short deadlines. If one appears on your title, speak to a lawyer quickly. Our page on construction and general liens gives a broader overview.
Refusing payment can be entirely legitimate where the work is deficient. The safer approach is to withhold an amount you can justify, explain why in writing, and keep that explanation factual.
Write a Letter Worth Reading
Before a claim is issued, a clear written demand often does more than a dozen angry calls. A useful letter identifies the contract and the address, lists the specific problems, attaches photographs or the independent assessment, sets out the amount or the corrective work you are seeking, and gives a firm and reasonable deadline. Keep it free of insults, threats, and speculation about the contractor’s character. A judge may eventually read it.
You can also complain to the province. Ontario’s consumer protection office accepts complaints about home renovation businesses and asks consumers to try to resolve the issue with the business first. It may be unable to help with events more than two years old, and it does not act as your personal collection agent. Its Consumer Beware List is also worth checking. Filing a complaint does not stop any limitation clock, so it should not replace legal action if a deadline is approaching.
If you want to warn others, a truthful online review is one thing. Accusations of fraud or criminal behaviour that you cannot prove can expose you to a defamation claim, so wait until you have had advice on anything stronger than a factual account.
Choosing the Right Court
For most renovation disputes, the main question is the amount. The Small Claims Court handles money claims up to $50,000, not counting interest and costs. In Brampton, the Small Claims Court sits at the courthouse at 7755 Hurontario St. The process is designed to be usable without a lawyer, although many people still get help with drafting or preparing for trial. You can read more on our small claim matters page.
If your loss is higher, you can sue in the Superior Court of Justice, or give up the excess to stay in Small Claims. Superior Court carries more steps, more cost, and greater exposure to the other side’s legal costs if you lose. Waiving part of a claim can be a sound business decision. Run the numbers carefully with someone who can estimate both routes.
Some points to think through before filing:
- Who are you suing? Your contract may be with a corporation rather than the person you dealt with. Search the corporate name and check the exact wording on the contract and invoices. A judgment against a shell company with no assets offers little comfort.
- Can they pay? Winning and collecting are separate problems. Ask whether the contractor has assets, ongoing work, or insurance that might respond.
- Is there a counterclaim? If you still owe a balance, expect the contractor to claim it. Include the value of completed work in your calculations so your claim stays credible.
The Two-Year Clock
Under Ontario’s Limitations Act, 2002, you generally have two years from the day you discovered your claim to start a court proceeding. Discovery can be earlier than you think. If you noticed the leak in the first spring after the work, the clock may have started then, even if you spent the following year politely waiting for the contractor to fix it. Promises to return and repair do not reliably pause time.
Hidden defects can raise harder questions about when you ought to have known about a problem. Keep records of when you first noticed each issue, and do not assume you have the full two years.
Getting Help, and Keeping Perspective
Not every failed renovation should end in a lawsuit. A negotiated credit, a third-party repair paid for by the contractor, or a modest settlement can be better than two years of litigation over a bathroom. A good assessment weighs the size of your loss, the strength of your proof, the contractor’s ability to pay, and the stress you are willing to take on.
If you would like to talk it through, bring your contract, payment records, photographs, and timeline to a consultation with a lawyer in our civil litigation group. Once the facts are organized and the numbers are on one page, the problem usually feels much more manageable, even when the kitchen still looks the same.
