Is it legal for a contractor in Ontario to ask for a deposit?

Yes, asking for a deposit is entirely legal and standard practice in Ontario. There is no law that prohibits deposits for trades work; however, the amount should be reasonable (generally 10–30%) and the terms should be spelled out in a written contract.

What should I do if a contractor disappears after taking my deposit?

File a report with your local police and the Ontario Ministry of Government and Consumer Services. If you paid by credit card or e-transfer through certain banks, you may be able to dispute the charge. This is one reason to avoid paying large deposits in cash, as cash transactions leave almost no recourse.

Do I need to verify WSIB coverage even for small jobs?

Yes. If a worker is injured on your property and the contractor does not have valid WSIB coverage, you as the homeowner could be held liable for costs. Request a WSIB Clearance Certificate for any job, regardless of size, and verify it directly on the WSIB website before work starts.

What is a holdback and does it apply to my home renovation in Ontario?

A holdback is a percentage of payment withheld until the work is fully complete and the lien period has expired. Under Ontario's Construction Act, a mandatory 10% holdback applies to many construction projects. Even if your project falls below the Act's threshold, voluntarily holding back 10–15% until final completion gives you practical leverage to ensure deficiencies are fixed.

How can I check if a contractor is licensed in Ontario before paying a deposit?

You can verify electrical contractors and electricians through the ESA website, gas fitters through the TSSA, and certified tradespeople through the Ontario College of Trades (now administered under the Ontario government's skilled trades framework). Always ask for a licence or certificate number and confirm it independently — never rely solely on what the contractor tells you.

How Much Deposit Should a Contractor Ask For in Ontario? (2026)

You've found a contractor you like, the quote looks reasonable, and they're asking for money before the work begins. That's completely normal — but how much is fair, and when should a deposit request make you nervous? For GTA homeowners, understanding contractor deposit norms can be the difference between a smooth renovation and losing thousands of dollars to a fraudulent operator. Here's what you need to know before you hand over a single dollar.

What Is a Normal Contractor Deposit in Ontario?

For most residential trades work in the GTA, a deposit of 10 to 30 per cent of the total contract value is considered industry standard. This upfront payment covers a contractor's initial material costs and reserves time in their schedule. The exact percentage typically depends on the size and nature of the project:

Small jobs (under $5,000): A deposit of 10 to 20 per cent is typical. Some smaller trades — such as an electrician doing a panel inspection — may require no deposit at all.
Mid-size renovations ($5,000–$50,000): Expect a deposit in the 15 to 25 per cent range to cover materials like fixtures, lumber, or specialty electrical components.
Large projects ($50,000+): A deposit closer to 10 to 20 per cent is common because the overall dollar amount is already substantial, and payments are broken into multiple milestones.

Remember that all quoted prices from HST-registered contractors should include 13% HST or show it clearly as a separate line item. If a contractor is quoting large jobs entirely in cash with no HST, that is itself a warning sign worth noting.

Why Do Contractors Ask for a Deposit?

Legitimate contractors use deposits for practical business reasons. Materials often need to be ordered and paid for before a single tool touches your home. Specialty items — a custom electrical panel, a high-efficiency boiler certified under TSSA (Technical Standards and Safety Authority) requirements, or bespoke cabinetry — can require significant lead time and upfront supplier payments. A deposit also compensates the contractor if a homeowner cancels after materials have been purchased. In short, a reasonable deposit protects both parties.

Progress-Payment Schedules: The Smarter Way to Pay

For any renovation over a few thousand dollars, a progress-payment schedule is far safer than a large lump sum. Instead of paying 50 per cent upfront and the rest on completion, you tie payments to specific, verifiable milestones. A well-structured schedule might look like this:

Deposit (10–25%): Paid on signing the written contract, before work begins.
First progress payment (25–30%): Released when rough work is complete — for example, after rough-in electrical or plumbing is inspected.
Second progress payment (25–30%): Released at a clearly defined mid-point, such as drywall installation or tile completion.
Final payment (15–20%): Paid only after all work is finished to your satisfaction, permits are closed, and any deficiencies are corrected.

Holding back a meaningful final payment — sometimes called a holdback — gives you real leverage to ensure the job is completed properly. Under the Ontario Construction Act, owners are actually required to hold back 10 per cent of the price of services and materials on projects subject to the Act, protecting against liens. Even on smaller jobs, voluntarily applying this principle is smart practice.

Red Flags: When a Deposit Request Signals Fraud

Not every contractor asking for a large deposit is operating in good faith. The following are serious warning signs that should make any GTA homeowner pause:

Demanding 50% or more upfront: Legitimate contractors rarely need half the contract value before starting. A request for 50, 60, or even 100 per cent upfront is a common tactic used by fraudulent operators.
Cash only, no receipt: Reputable contractors accept cheques or electronic transfers and provide written receipts. Insisting on cash with no paper trail removes your ability to dispute charges or prove payment.
No written contract: A verbal agreement is extremely difficult to enforce. Every project should have a written contract outlining scope, materials, timeline, payment schedule, and warranty terms.
High-pressure urgency: Phrases like "I need the deposit today or I'll give the slot to someone else" are designed to prevent you from doing due diligence.
No verifiable credentials: In Ontario, electricians must be licensed through the Electrical Safety Authority (ESA), gas fitters through TSSA, and skilled tradespeople in over 20 compulsory trades must hold certificates through Ontario College of Trades (OCOT). Any contractor unwilling or unable to provide their licence number is a red flag. You should also confirm active WSIB (Workplace Safety and Insurance Board) coverage to protect yourself from liability if a worker is injured on your property.

How to Protect Yourself Before Paying Any Deposit

A few practical steps can dramatically reduce your risk as an Ontario homeowner:

Always get at least two or three written quotes before committing.
Verify licences directly with ESA, TSSA, or OCOT — do not rely solely on a contractor's word or a logo on their truck.
Request a WSIB Clearance Certificate and confirm it is current before work begins.
Pay by cheque or e-transfer so there is a documented paper trail.
Never pay the full deposit in one cash transaction, even if the percentage itself seems reasonable.
Ensure your written contract specifies what happens to the deposit if either party cancels.

The Bottom Line

A deposit of 10 to 30 per cent, tied to a clear written contract and a milestone-based payment schedule, is normal and fair for trades work in the GTA. Anything that deviates significantly from that range — especially large cash-only demands with no paperwork — deserves serious scrutiny. Taking the time to verify credentials, ask questions, and structure payments properly is the single most effective way to protect your home and your wallet.
