Deposits, Payment Schedules and Contracts: What Ontario Homeowners Should Know

The general rule: never pay in full up front

This is the single most important rule in this guide, and it is worth stating plainly. A contractor who asks for full payment before any work begins is asking you to absorb all of the risk in the relationship. If the job goes poorly, is left unfinished, or the company disappears, you have already handed over your only real leverage. Reputable contractors do not need to ask for this, because a staged schedule tied to progress protects their cash flow just as well while keeping the arrangement fair.

What a reasonable deposit looks like

Deposits exist for a legitimate reason. They let a contractor order materials, schedule crews and commit to your project instead of someone else's. A reasonable deposit is usually a modest percentage of the total contract value, often enough to cover initial material costs, not the bulk of the job. Exactly what counts as reasonable can vary by project size and by what materials need to be ordered up front, so ask the contractor to explain what the deposit is specifically covering rather than accepting a round number without context.

• Ask what the deposit pays for specifically, such as materials that need to be special-ordered.
• Be more cautious of a large deposit on a large project, since the dollar exposure is higher even if the percentage looks similar.
• A deposit should be described in the written contract, not just requested verbally or over text.
• Pay deposits by a traceable method, cheque or e-transfer with a clear record, rather than cash.

Staged payments tied to milestones, not the calendar

Beyond the deposit, the rest of the contract price should be broken into stages tied to completed, verifiable work, not simply spread evenly across the calendar. A payment schedule tied to milestones means you are always paying for work you can see, which keeps the incentives aligned for both sides.

1. 01

   Deposit at signing

   Covers initial materials and secures your spot in the schedule.

2. 02

   Progress payment at a defined milestone

   For example, once framing or footings are complete and pass any required inspection, not simply after a set number of days have passed.

3. 03

   Progress payment at a second milestone

   For example, once major materials are installed, such as decking, siding or cabinetry, and before finishing details.

4. 04

   Final payment on completion

   Paid once the work is finished, inspected if applicable, and you have had a chance to walk through it. This is also the natural point to apply any holdback.

A schedule with only two payments, deposit and final, can work for smaller jobs. For anything running several weeks or longer, more stages give both sides a clearer picture of where things stand and reduce the size of any single payment that is exposed if something goes wrong partway through.

Holdbacks: what they are and when they apply

A holdback is a portion of the final payment withheld for a period after substantial completion, giving you time to confirm the work holds up and giving subtrades and suppliers a window to file a claim if they were not paid by the general contractor. Construction lien holdback rules in Ontario apply in certain circumstances and are more relevant on larger projects, particularly ones involving multiple subcontractors or larger dollar values, than on a small repair job. If your project is significant in scope or cost, it is worth asking your contractor directly how they handle holdbacks and, if the amounts involved are large, confirming your understanding with a lawyer rather than relying on general guidance.

Practically, even outside of formal lien holdback rules, it is reasonable for a homeowner to hold back a final portion of payment, often in the range of ten percent, until any deficiencies identified during a walkthrough are fixed. This should be agreed to in the contract up front rather than announced as a surprise at the end.

Ontario's Consumer Protection Act and the cooling-off period

Ontario's Consumer Protection Act includes rules that apply specifically to contracts signed away from the seller's regular place of business, commonly called direct sales or door-to-door contracts. If a contractor signs you up at your kitchen table after an unsolicited knock on the door, rather than at their office or showroom, that contract may fall under these direct sales rules, which generally include a cooling-off period, often ten days, during which you can cancel without penalty.

• This cooling-off protection generally applies to direct sales contracts, not contracts you initiate yourself by visiting a contractor's office or calling them after researching options.
• If a contract is covered, cancellation rights and the process for exercising them are supposed to be disclosed to you in writing at the time of signing.
• If in doubt about whether a specific contract qualifies, Ontario's Ministry of Public and Business Service Delivery publishes consumer protection guidance that can clarify how these rules apply to your situation.

Put the whole schedule in the written contract

None of this matters if it only exists as a verbal understanding. The deposit amount, the milestone schedule, the holdback terms and the total contract price should all appear in a single written contract signed before any money changes hands. If you are also comparing multiple quotes at this stage, it is worth reading how to read a contractor quote alongside this guide, since a clear payment schedule and a clear scope tend to come from the same well-run companies.
