What's a typical deposit for a contractor in Canada? (And when 50% is a red flag)

The deposit question is usually asked backwards. Homeowners ask “what percentage is normal?” when the question that actually protects you is “what is each payment tied to?” After 19 years on the contractor's side of these schedules, here is how to read one properly.

What's a standard contractor deposit?

Deposits on residential work commonly run 10–25%. The honest reasons a deposit exists: it commits your spot in the contractor's schedule, and it funds upfront material orders. That second reason is why the percentage legitimately varies — a deck built from lumber bought the week work starts needs little upfront; a kitchen with custom cabinetry on a six-week lead time may reasonably carry a larger deposit, because the contractor is writing a five-figure cheque to the cabinet shop long before installation.

So when a deposit looks high, the question isn't “is this a scam?” It's: “what does the deposit cover?” A specific answer — “cabinet order, window order, permit fees” — is reassuring. A vague one is not.

What's a reasonable deposit amount?

Beyond common practice, two Canadian authorities have put numbers in writing. The Canadian Home Builders' Association's Get it in Writing! guidance says deposits “should not generally exceed 10% of the total cost of the work” — with one exception: custom materials or products you've requested that are not returnable and must be pre-paid by the contractor, where an additional deposit is to be expected.

Ontario adds a protection at the other end of the project. Under the province's Consumer Protection Act guidance, if an estimate is included as part of a home renovation contract, the final price cannot be more than 10% over that estimate unless you've agreed to new work or a new price and signed a change to the contract. Together, the two rules bracket your money: the guidance keeps the deposit small at the start, and the estimate rule holds the total at the end.

The structure matters more than the percentage

A payment schedule has one job: keep money paid roughly in line with work completed, all the way to the end. The protective pattern looks like this:

• Deposit — 10–25%, sized to real upfront commitments.
• Progress draws tied to milestones — “on completion of demolition,” “on rough-in inspection passing,” “on drywall complete.” Milestones you can see with your own eyes.
• A meaningful final payment on completion — due when the punch list is done, not on a calendar date. This is your leverage for the last 2% of the job, which is famously the hardest part to get finished.

Is a 50% deposit normal? The actual red flags

• Large deposit with no stated purpose — 40–50%+ on a mid-size job with no material-order explanation. If that's the ask you're facing, here's what to do about a 50% deposit demand.
• Nearly everything due before completion — any schedule where 90%+ is paid while real work remains.
• Cash-only with no paper — beyond the obvious risks, a price that only exists in cash usually means no HST, which often travels together with no insurance and no warranty. The discount is rarely worth what it silently removes.
• Pressure to pay the deposit today — legitimate schedules survive a few days of thought.

One more Canadian wrinkle worth knowing exists: on larger projects, provincial builders' lien legislation involves holdbacks — a percentage retained from payments for a statutory period to protect against liens from unpaid subcontractors. Most modest renovations never engage with this formally, but on a major project it is worth asking your contractor — or a lawyer — how holdback applies in your province. A contractor who understands the question is itself a good sign.

Payment schedule problems are quote problems — they are visible on the page before you sign, sitting right next to the allowances and the scope language covered in the main guide. Five minutes of reading the schedule against the “what is each payment tied to?” test catches nearly all of them. If it's the whole number that's worrying you, not just the schedule, here's how to check a quote you're unsure about.
