Key Takeaways
- Ontario's consumer protection guidance recommends keeping a renovation deposit to no more than 10% of the contract price, and never paying the full amount before the work is done.
- If you sign the contract at your home rather than at the contractor's place of business, it's treated as a "direct agreement" under the Consumer Protection Act, which comes with a 10-day cooling-off period and specific contract-content rules.
- The Consumer Protection Act also caps cost overruns: the final price can't run more than 10% over a written estimate unless you've signed off on the extra work first.
- Industry bodies like the Canadian Home Builders' Association and the Better Business Bureau both treat a demand for 100% upfront, or a deposit north of 25-30%, as a warning sign, not a normal ask.
- A payment schedule tied to real milestones, framing, rough-in, pour day, final walkthrough, protects both sides better than either a lump sum or a pile of tiny weekly invoices.
What's a normal deposit on an Ontario renovation contract?
Smaller than most homeowners expect the first time they see a contractor's proposal. Ontario's own guide for home renovation and roofing businesses recommends keeping deposits to a minimum, "no more than 10%" of the total project cost, and it's blunt about the other end of the transaction too: never pay the full amount of the contract before the work is done. The Canadian Home Builders' Association lands in the same range, telling homeowners that deposits "should not generally exceed 10% of the total cost of the work," with the usual carve-out for special-order materials, custom cabinetry or an imported tile that a supplier needs paid for before it ships.
Deposits and payment schedules are one piece of a bigger vetting process, covered in full in how to choose a renovation contractor in Ontario, but they're often the first concrete number that tells you what kind of contractor you're dealing with. That 10% figure isn't a hard legal ceiling everywhere in the province. It's a recommendation, repeated by government guidance and industry associations because it lines up with how a legitimate contractor actually spends the money: a small amount to lock in scheduling and cover initial material orders, not to fund the job before a single wall comes down. Some contractors quote a bit higher, and the Better Business Bureau puts the broader normal range at 10-30% depending on project size and material lead times. What both sources agree on is the shape of a bad deal: anything that starts creeping toward half the contract price before work begins is outside normal territory.
Does Ontario law actually require a maximum deposit?
Not as a flat rule for every renovation contract, and this is where a lot of online advice oversimplifies. The Consumer Protection Act, 2002 draws a distinction based on where you sign, not on what trade you hired. A "direct agreement" is a contract negotiated or signed in person somewhere other than the contractor's place of business, which in practice covers most renovation deals: the contractor comes to your house for the measure, and you sign the quote at your kitchen table. Sign that way and the Act's specific protections kick in, including a 10-day cooling-off period and requirements that the contract itself spell out the deposit amount, the payment schedule, and the estimate.
Where it gets murkier is a contract you sign at a showroom, a design centre, or the contractor's own office. That's not automatically a "direct agreement" under the Act, and the specific consumer protections attached to that category may not apply the same way. Ontario's own guidance on your rights when starting home renovations or repairs doesn't hand every in-person renovation contract identical treatment just because a human signed a piece of paper in front of another human, it matters where that signing happened. If you're not sure which category your contract falls into, that's a fair question to put directly to whoever you're hiring, not something to assume. A written, itemized quote settles most of the ambiguity anyway, because it forces the deposit and payment schedule onto paper regardless of which legal category the signing location puts you in.
Why is a 100% upfront demand treated as a red flag everywhere?
Because there's no legitimate reason for it. A contractor who has secured your full payment before framing a single wall has no financial reason left to show up, finish on schedule, or fix anything that goes wrong. The BBB states it plainly: never pay the total project cost upfront, even when a contractor offers a discount for doing it, and treat any request for more than half the contract price before work starts as a reason to slow down and ask harder questions. That's not a niche caution aimed at unlicensed operators, it's standard guidance repeated across consumer protection agencies and trade associations because the pattern shows up in scam complaints often enough to name it outright.
The mechanics of a renovation explain why the industry lines up on this. A legitimate contractor's costs are staged, not front-loaded: a deposit to hold your slot and order the first materials, then payments tied to completed phases as labour and materials actually get consumed. A 100% upfront ask skips every one of those checkpoints and leaves you with no leverage if the crew doesn't show, the material is wrong, or the work fails inspection. It's the same logic behind a broader pattern we cover in red flags to watch for when hiring a renovation contractor: a demand for full or unusually large payment before work starts is one of the clearest, most consistent signals that something else about the deal is likely off too.
What should a payment schedule actually look like?
Tied to milestones you can see and verify, not to a calendar. CHBA's guidance is specific on this point: payment terms should set out how and when each instalment is due, at regular intervals or against defined progress stages, and a price quote should note what portion of the work each payment is tied to. That's the difference between a schedule you can hold a contractor to and a vague promise to "pay as we go."
On a kitchen or bathroom job that usually breaks down into something like: deposit on signing, a payment when materials are ordered or delivered, a payment at rough-in (once plumbing and electrical are open and inspected), and a final payment on completion, held until the punch list is actually clear. A concrete pour follows the same principle on a shorter timeline: base preparation and forming, the pour itself, and a final payment after the cure period and finish work are done. In both cases the underlying rule doesn't change, you're paying for work that's already happened or materials that are already on site, not work that might happen next week.
The Consumer Protection Act adds one more piece of leverage on top of the payment schedule itself: the final price on an estimate-based contract can't run more than 10% over the original number unless you've agreed to the extra work and signed a revised estimate first. A written, itemized quote and a change-order process for anything that changes mid-project is what actually enforces that cap in practice, which is exactly the shape covered in why an itemized quote matters more than a low price and in how to actually read a renovation contract before you sign.
| Payment stage | What it should be tied to | Roughly when |
|---|---|---|
| Deposit | Signing the contract, locking the schedule, ordering the first materials | Contract signing |
| Materials/progress payment | Materials on site or delivered, first phase of labour complete | Early in the build |
| Rough-in payment | Framing, plumbing, and electrical open and passed inspection | Mid-project |
| Final payment | Punch list cleared, site cleaned, warranty documents handed over | Completion |
How does this play out on a real renovation or concrete job?
Every project we run, in the GTA and across Kitchener-Waterloo-Cambridge, Guelph, Hamilton, and Niagara, starts the same way regardless of trade: an on-site measure, then a written, itemized quote before any deposit changes hands. That quote is fixed, and it's what gets billed against as the job moves through its stages, so a scope change part way through means a signed change order with a new number attached to it, not a surprise on the final invoice. That structure is what a payment schedule is actually protecting, on either side of the transaction.
The specifics still vary by trade. A bathroom renovation in Hamilton usually runs payments against plumbing rough-in and waterproofing before tile goes down, because those stages are the ones that are expensive to redo once they're covered. A flooring installation in Cambridge is shorter and simpler, often just a deposit and a completion payment, since there's rarely a hidden rough-in stage hiding behind the finish. Concrete work compresses the whole schedule into days rather than weeks: a concrete steps project in Kitchener is typically deposit, then a payment once forming and the pour are done, then final payment after the cure period, because there isn't much daylight between "started" and "finished" on a job that size.
Frequently asked questions
Is a 10% deposit a legal requirement in Ontario?
No, it's a recommendation from Ontario's consumer protection guidance and echoed by industry bodies like CHBA, not a hard statutory cap that applies to every renovation contract. What the Consumer Protection Act does set as a firmer rule, for contracts that qualify as direct agreements, is the 10-day cooling-off period and the requirement that the contract itself disclose the deposit and payment schedule in writing.
What should I do if a contractor asks for 50% or more upfront?
Ask why, in specific terms, before agreeing to anything. A legitimate reason exists sometimes, custom-ordered materials with a long lead time and a supplier that requires prepayment being the most common one, and a contractor should be able to explain that clearly and show it on the written quote. If the answer is vague, or the request is simply "that's how we do it," treat it the way the BBB and CHBA both frame it: as a deviation from normal practice that's worth walking away from rather than negotiating down.
Can a contractor legally raise the price after I've signed a quote?
Only within limits, and only for work you've actually agreed to. Under the Consumer Protection Act, the final price on an estimate-based contract can't exceed the original estimate by more than 10% unless you've approved new work or a new price along the way, which is normally handled through a signed change order. That's part of why a written, itemized quote matters more than a low headline number, it's the document that makes this cap enforceable in the first place.
What's a holdback, and is it the same thing as a deposit?
No. A holdback is the opposite end of the payment schedule: a percentage of each payment that you retain for a set period after work is done, as protection against a subcontractor or supplier placing a lien on your property if the contractor doesn't pay them. A deposit happens at the start of a project to secure your booking; a holdback happens at the end to protect you after the fact. Both should show up in a properly written contract, and neither should be skipped because a contractor asks you to.
Bottom line
A reasonable Ontario renovation deposit sits in roughly the 10% range, tied to a payment schedule that follows real, verifiable stages of the work rather than a calendar or a lump sum. A written contract signed at your home generally gives you the Consumer Protection Act's direct-agreement protections, including the cooling-off period and the 10% cap on cost overruns above a signed estimate, though the same protections don't automatically extend to a contract signed at a contractor's own premises. None of this is unique to any one trade or any one company, it's the baseline every legitimate renovation or concrete contractor in the province should already be working to. If a quote you're holding doesn't spell out the deposit, the payment schedule, and what happens if the scope changes, that's worth raising before you sign, not after.
