Hiring a Renovation Contractor in Ontario: The Checklist
Last updated · Filteraty Editorial
Protecting yourself when hiring an Ontario renovation contractor comes down to sequence: check the credentials that apply to the work, put the full scope in a written contract before money moves, keep the deposit proportionate to work actually started, understand your Consumer Protection Act rights, and settle in writing who pulls any permit.
What should you verify before you shortlist anyone?
The credentials that actually apply to your project, which in Ontario depends on the work, not on a single licence. Electrical work needs an ESA-licensed contractor, gas work a TSSA-registered one, plumbing a certified tradesperson, and in Toronto the business itself needs a municipal renovator licence. Our licence-checking guide walks each free lookup step by step, and the Consumer Beware List shows businesses charged under consumer protection law.
Do this before collecting quotes, not after falling in love with one. A shortlist built from verifiable companies makes every later step cheaper.
What belongs in a renovation contract?
Everything you would otherwise have to argue about later: the full scope of work in specific terms, the price and what it excludes, start and completion dates, a payment schedule tied to work stages, how changes get priced and approved in writing, who obtains permits, cleanup and disposal, and warranty terms. Ontario’s consumer protection rules require written contracts for home renovation agreements above a modest threshold. But the legal minimum is beside the point; the contract is the instrument that makes two people mean the same thing by "finish the basement."
A contractor who resists writing the scope down is telling you how change orders will go. The written scope also powers everything else on this page: quotes become comparable, the deposit becomes proportionate to something, and disputes become checkable against a document.

How much deposit is reasonable?
Ontario law sets no general cap on renovation deposits, so proportion is your protection: enough to cover materials the contractor must order for your job, and no more. Commonly that lands around ten to fifteen percent of the contract price. A demand for half the job up front, or for cash, is a risk transfer from the contractor to you, and renovation-deposit fraud cases in the GTA regularly begin exactly there.
Tie every subsequent payment to completed, visible work stages in the contract, and keep the final payment large enough to matter until deficiencies are corrected. The payment schedule is not bookkeeping; it is your leverage, spent down as the job progresses.
What rights does the Consumer Protection Act give you?
Ontario’s Consumer Protection Act gives homeowners specific rights that renovation situations trigger more often than most: a cooling-off period for contracts signed after a salesperson comes to your door, rules against charging far above an estimate without your agreement, and remedies when contracted work is not delivered. The exact rules and current thresholds are laid out on the province’s own page, which is the version worth trusting over any blog summary, including this one.
The practical takeaway: if you signed at your kitchen table under time pressure, you likely have more room to reverse than you think, but the clock is short. Check the province’s page the same day, not next month.

Who should pull the building permit?
Settle it in writing before work starts, because the answer changes your risk. Permits exist for structural changes, most basement conversions, plumbing and electrical alterations, and more. Work done without a required permit can mean orders to expose or redo finished work, plus complications when you sell. In Toronto, the city’s building division publishes what needs a permit and how to apply.
Many contractors pull permits routinely and price it in; some quote low by quietly leaving permits to you or skipping them. "Who obtains and pays for permits?" is a one-line contract clause that prevents the most expensive category of surprise a renovation can produce.

What are the red flags worth walking away from?
Most renovation disasters announce themselves early, in a pattern regulators and police warnings describe consistently. The common thread is urgency: pressure to decide today, pay today, or skip a step that exists to protect you. Legitimate contractors in the GTA are busy, and a busy professional is rarely in a hurry to close you.
Any one of these is a conversation worth having; two or more together is an answer. Walking away costs you a few days of scheduling; the alternative has cost GTA homeowners their deposits and, in the worst cases, a half-finished house.
- •Door-to-door solicitation with "we’re doing work in the area" pricing that expires today
- •Large deposit demanded up front, especially in cash
- •No written contract, or a one-paragraph "contract" with no scope
- •No verifiable licence number, insurance certificate, or WSIB answer (see our verification guides)
- •Pressure to skip permits "to save you money"
- •A quote dramatically below every other bid: the risk has not vanished, it has moved to you
How does this work on Filteraty?
Filteraty handles the first step for you: contractors are screened against Ontario’s public registries before matching, and each profile shows what was checked and when. The rest of the checklist stays in your hands by design: you contract and pay your contractor directly, Filteraty is not a party to that agreement, and the contract you sign is between the two of you. Describe your project once and you will be comparing quotes from companies whose verification records you have already read.
Common questions
Do I need a written contract for a small job?
Make one anyway. Ontario’s consumer protection rules require written agreements for home renovations above a modest dollar threshold, but the contract’s real job is defining scope, and scope disputes happen on the smallest jobs as reliably as on the largest. One page with scope, price, dates and payment terms is enough for small work.
Can I cancel after signing?
Sometimes. Ontario’s Consumer Protection Act provides a cooling-off period for agreements signed as a result of door-to-door contact, and other remedies in specific situations. The rules and current thresholds are on ontario.ca; check them immediately, because the windows are short.
Should I ever pay in cash?
A cash discount usually means no paper trail, no HST, and often no contract, which is precisely the protection you are selling for the discount. If something goes wrong on a cash job, you may have nothing showing the work was ever commissioned.
What if the work fails inspection or has deficiencies?
This is what your held-back final payment exists for. Document deficiencies in writing against the contracted scope, give the contractor the contractual chance to correct them, and pay the balance when they are corrected. If the contract ties payments to stages, an unresolved deficiency list is a stage not yet complete.
