Suing a bad contractor in Toronto costs between $108 and $308 CAD in basic court fees for Small Claims Court (for damages up to $50,000 CAD). If your financial damages exceed this limit, you must file in the Superior Court of Justice, where lawyer retainers and expert builder reports can quickly push your costs above $15,000 CAD.
Hiring a contractor to renovate your kitchen, finish your basement, or fix your roof is a major investment. 🛠️ Unfortunately, many Toronto homeowners find themselves dealing with half-finished jobs, massive delays, or dangerously poor workmanship. When a contractor takes your hard-earned money and leaves your home in a state of disrepair, taking legal action may be your only option to recover your losses.
Before rushing to file a lawsuit, it is important to understand the financial realities of civil litigation in Ontario. ⚠️ Suing a contractor is not free, and the process requires strict adherence to legal procedures. Most applicants in this province must carefully weigh the cost of legal fees and expert reports against the actual amount of money they hope to recover from the builder.
Step-by-Step Process in Toronto
Whether your property is in North York, Scarborough, or downtown Toronto, the process for suing a contractor depends entirely on the amount of money you are claiming. 📝 Claims for $50,000 CAD or less belong in the Small Claims Court, while larger claims must go to the Superior Court of Justice. Here is the standard process for building your case.
Step 1: Document the Poor Workmanship
Evidence is the foundation of any successful civil dispute. 📂 Before you allow another contractor to fix the mess, take dozens of clear, high-resolution photographs and videos of the defective work. Keep copies of the original contract, all text messages, emails, and proof of every payment or cheque you gave to the contractor.
Step 2: Hire an Expert Builder for a Report
A judge is a legal expert, not a construction expert. To prove the workmanship is legally “poor,” you usually need an independent expert to evaluate it. 🔍 You should hire a licensed engineer, architect, or a reputable Toronto contractor to inspect the work and write a formal expert report. This report will detail exactly what building codes were violated and provide an estimate to fix the damage.
Step 3: Send a Final Demand Letter
Before initiating a lawsuit, send a formal demand letter to the contractor’s registered business address. ✉️ Having a local law firm or paralegal draft this letter shows the contractor you are serious. Give them a strict 10-to-14-day deadline to either refund your money or pay for the damages outlined in your expert report.
Step 4: File Your Claim at the Proper Courthouse
If the contractor ignores the letter, you must file a Plaintiff’s Claim. 📄 If the damage is under $50,000 CAD, you will file at the Toronto Small Claims Court. If it exceeds $50,000, your lawyer will issue a Statement of Claim in the Superior Court of Justice. The court will stamp your documents, and you must then have them officially served to the contractor.

How Long Does the Process Take?
Civil litigation moves slowly. ⏳ If your case is in the Toronto Small Claims Court, expect it to take 10 to 18 months from filing your claim to getting a trial date. If you are pursuing a larger lawsuit in the Superior Court of Justice, the mandatory steps of pleadings, documentary discovery, and mediation mean it will typically take 2 to 4 years to reach a final trial.
Frequently Asked Questions (FAQ)
What if the contractor’s company went bankrupt?
If the contractor’s incorporated business has officially filed for bankruptcy, all legal actions against the company are automatically paused (stay of proceedings). You will have to file a claim as an unsecured creditor, and unfortunately, you may only recover pennies on the dollar.
Can I sue for the stress they caused me?
Generally, Ontario courts award damages strictly to compensate for actual financial losses (like the cost of hiring a new builder). While aggravated or punitive damages for mental distress are possible, they are exceptionally rare in standard breach of contract cases.
Do I need a lawyer for Small Claims Court?
You are allowed to represent yourself in Small Claims Court. However, many Torontonians choose to hire a licensed paralegal or a law firm, as they understand the Rules of the Small Claims Court and can handle the complex paperwork and trial procedures for you.
How long do I have to sue my contractor?
Under the Limitations Act of Ontario, you generally have exactly two years from the day you discovered the defective work (or the day the contractor walked off the job) to officially file your lawsuit. If you miss this deadline, your claim is legally barred.
