Your Contractor Hiring Checklist

Contractor Selection, Contracts & Homeowner Protection May 11, 2026 By ALDO Homes
Your Contractor Hiring Checklist

This checklist brings together everything uncovered in the first two parts of the Aldo Homes Homeowner Protection Series — the warning signs of contractor fraud and the legal gaps that leave Ontario homeowners exposed. It is not a generic list of tips. It is a step‑by‑step defence system built directly from real scam patterns, real enforcement failures, and the nine systemic loopholes that dishonest contractors exploit across the province.

If Part 1 showed you how scams actually happen, and Part 2 revealed why the legal system often can’t stop them, this final guide gives you the practical, actionable process that closes those gaps. Every step in this checklist corresponds to a specific vulnerability documented in real cases — from verifying insurance directly with the insurer, to searching a contractor’s personal litigation history, to enforcing the statutory holdback that protects you from liens.

At Aldo Homes, we believe homeowners deserve more than warnings — they deserve a clear, structured method to protect their home and their money. This checklist is the method. Whether you’re planning a small repair or a major renovation, these steps provide the same due diligence framework we would want for our own family. In a province where renovation contractors are not licensed, warranties don’t apply, and enforcement is limited, a methodical hiring process is the strongest protection you have.

📘 1. Introduction — This Checklist Is Built on Real Gaps {#1-introduction—this-checklist-is-built-on-real-gaps}

This checklist distills everything from the Aldo Homes Homeowner Protection Series into a single, actionable tool. It is not a generic guide assembled from best practices — it is built directly on the warning signs documented in real scam cases affecting Ontario homeowners, as well as the nine systemic loopholes we identified in Ontario’s legal and regulatory framework. Every step below addresses a specific vulnerability that has cost real families real money.

This checklist is built on the warning signs and legal gaps we’ve documented. If you haven’t already, we strongly recommend reading the first two parts of this series: How to Spot a Contractor Scam in Ontario (Part 1) and Ontario Contractor Laws — What Protects You (and What Doesn’t) (Part 2). Together, they provide the full context for each step you’ll find below.

Here is the uncomfortable core truth: the single most effective protection available to you is not a law, not a government registry, and not a warranty program. It is your own informed, methodical vetting process. The 20 steps that follow are designed to give you exactly that — a structured process that closes the gaps the system leaves open.

🧭 2. Before You Contact Any Contractor {#2-before-you-contact-any-contractor}

Why This Phase Matters

The work you do before contacting a single contractor determines whether you can evaluate quotes accurately, spot red flags early, and negotiate from a position of knowledge rather than hope.

  1. Define your scope of work in writing.

    • Even a rough description helps you compare quotes accurately and ensures every contractor is bidding on the same work. Include the areas of the home affected, the type of work required (demolition, structural, electrical, plumbing, cosmetic), and your desired outcome. This document becomes the basis for every quote you receive.
  2. Research permit requirements.

    • Call your municipality’s building department to find out which permits are required for your project. Do not rely on the contractor’s word for this. Permit requirements vary by municipality, and a contractor who tells you “no permits are needed” for work that clearly involves structural, electrical, plumbing, or HVAC changes is either uninformed or deliberately avoiding oversight.
  3. Set a realistic budget.

    • Get informal estimates from at least one trusted source — a knowledgeable friend, a building supply store, or an online estimator — before soliciting formal quotes. This gives you a baseline to identify quotes that are suspiciously low. A quote that undercuts the market by 30–40% is not a bargain; it is a warning sign.

📝 3. During the Quoting Process

Key Principle: This is the phase where the majority of contractor scams can be prevented. Every step below targets a specific tactic used by fraudulent contractors to bypass scrutiny.

  1. Get a minimum of three written quotes.

    • Be wary of any quote dramatically lower than the others. A significantly lower quote may indicate the contractor plans to cut corners on materials, skip permits, or inflate costs through change orders later. Equally, be cautious of vague quotes that lack line-item detail — these make it impossible to compare value or hold the contractor accountable.
  2. Verify business registration.

    • Search the contractor’s business name on the Ontario Business Registry. A legitimate contractor will have a registered business. If the business is not registered, treat this as a disqualifying red flag. Note the registration date — a brand-new registration on a company that claims years of experience warrants further investigation.
  3. Search the individual’s name — not just the company name.

    • Search on CanLII, the free Canadian legal database, for any court history. Also search on the Ontario Court database. Contractors who cycle through company names — dissolving one numbered company and creating another — can only be tracked by searching their personal name. This is one of the most important steps in the entire checklist.
  4. Request and verify insurance.

    • Ask for a current Certificate of Insurance showing both commercial general liability insurance and WSIB (Workplace Safety and Insurance Board) coverage. Do not accept a copy from the contractor alone — call the insurer and WSIB directly to confirm the policy is active and covers residential renovation work. Expired or falsified insurance documents are a common tactic.
  5. Check references independently.

    • Call at least two past clients provided by the contractor. Ask specific questions: Was the project completed on time? Were there unexpected cost increases? Would you hire them again? If possible, visit a completed project in person. A contractor who cannot or will not provide verifiable references is not worth your risk.
  6. Review online presence critically.

    • Look for a history of reviews over multiple years on Google, HomeStars, or other platforms. Be skeptical of profiles with only recent five-star reviews, no photos, or no organic web presence beyond paid advertisements. A legitimate contractor with years of experience will have a verifiable digital footprint — not just a polished ad.

📑 4. Before Signing the Contract

Warning: A verbal agreement is not a contract. If anything goes wrong, your ability to recover depends almost entirely on what is written down and signed. This section is non-negotiable.

  1. Insist on a detailed written contract that includes ALL of the following:

    • Full legal name and address of the contractor (matching their business registration)
    • Detailed scope of work, including specific materials to be used (brand, model, grade)
    • Total price and a payment schedule tied to specific milestones (not dates)
    • Start date and estimated completion date
    • Change-order process with clear pricing rules for any additions or modifications
    • Written warranty terms (what is covered, for how long, and how to make a claim)
    • Permit responsibilities (the contract should state that the contractor is responsible for pulling all required permits)
    • Dispute resolution process
  2. Never agree to more than 10–15% as a deposit.

    • A legitimate contractor can purchase initial materials with a modest deposit. A demand for 30–50% or more before any work begins is one of the most common indicators of fraud. This single rule — enforced consistently — would have prevented a significant number of the scam cases documented in Part 1 of this series.
  3. Ensure the contract specifies that the contractor is responsible for pulling all required permits.

    • If the contractor claims permits are not needed for work that clearly requires them (structural changes, electrical, plumbing, HVAC), this is a red flag. Verify independently with your municipality. Unpermitted work can result in fines, forced removal, insurance claim denials, and complications when selling your home.

🔧 5. During the Project

  1. Maintain the 10% statutory holdback under the Construction Act.

    • This is not optional. The holdback protects you from construction liens filed by unpaid subcontractors and suppliers. Under Ontario’s Construction Act, the holdback must be retained until 60 days after the last work is completed. Releasing the holdback early exposes you to personal liability for unpaid claims — even if you have already paid the general contractor in full.
  2. Pay only upon completion of defined milestones.

    • Never pay ahead of work completed. Your payment schedule should be tied to verifiable stages of completion (e.g., demolition complete, framing complete, rough-in inspected, drywall finished) — not to calendar dates. If a contractor pressures you to pay for the next phase before the current phase is finished, this is a red flag.
  3. Document everything.

    • Photograph progress daily. Keep all receipts, emails, text messages, and written communications. This documentation is your primary evidence if a dispute arises. Date-stamped photos are especially valuable. Create a simple folder system — digital or physical — organized by date, and back it up regularly.
  4. Request lien waivers from subcontractors and suppliers as work progresses.

    • A lien waiver (also called a statutory declaration) confirms that the subcontractor or supplier has been paid for their portion of the work. This protects you from liens being filed against your property even after you have paid the general contractor. Request these at each payment milestone.
  5. Never pay in cash (unless a written receipt is given)

    • Use a cheque or e-transfer to the registered business name only. If the contractor asks you to send payment to a personal account or requests cash to “save you the HST,” treat this as a serious red flag. Cash payments eliminate the paper trail you need for any future legal action and may also make you complicit in tax evasion.
  6. Tip

    • Keep a dedicated email thread or written log for all project communications. Verbal agreements made on-site should be confirmed in writing the same day — even a brief email that says “Confirming our discussion today about [change]” creates a valuable record.

📦 6. At Completion

  1. Do not release the holdback until 60 days after the last work is completed.

    • Release the holdback only after confirming that all subcontractors and suppliers have been paid. Request final lien waivers from all parties. The 60-day period is the window during which subcontractors can preserve a construction lien against your property. Releasing the holdback prematurely removes your only financial leverage.
  2. Obtain a final inspection from the municipality.

    • Confirm that all permitted work has been inspected and meets the Ontario Building Code. Request a copy of the inspection report for your records. This is essential if you ever sell the home or refinance. Unpermitted or uninspected work can reduce your home’s value and create liability.
  3. Get the warranty in writing.

    • Ensure the warranty document specifies exactly what is covered, for how long, and the process for making a claim. A verbal warranty is worth nothing in a dispute. Keep this document with your other project records permanently — warranties on workmanship and materials may extend for years beyond project completion.

🚨 7. What to Do If You’ve Been Scammed

If you believe you have been defrauded by a contractor, act quickly and methodically. The steps below are organized by urgency.

Immediate Steps:

  • Stop all further payments. Do not pay anything additional regardless of pressure or threats. Any demand for more money at this stage is an attempt to extract maximum value before disappearing.
  • Document everything you have — contract, receipts, photos of work done (or not done), text messages, emails, bank statements showing payments made. Organize this material chronologically. This is your evidence file.
  • Secure your property. If the contractor has keys or access codes, change locks and codes immediately. If your tools or materials are at risk, take steps to secure them.

Reporting

  • File a complaint with the Ministry of Public and Business Service Delivery at ontario.ca/consumer-protection.
  • Report to police. If the amount exceeds $5,000, the conduct may constitute criminal fraud under the Criminal Code of Canada. File a report with your local police service. Request a case number for your records.
  • File a complaint with the BBB (Better Business Bureau). This won’t recover money directly but creates a public record that warns other homeowners and may support future legal action.
  • Report to the Canadian Anti-Fraud Centre at antifraudcentre-centreantifraude.ca.
  • Report underground economy activity to the CRA Leads Program (by phone or online). If the contractor demanded cash payments or avoided charging HST, this is tax fraud in addition to contractor fraud.
  • For amounts up to $35,000, file a claim in Small Claims Court. You can represent yourself. The process is designed to be accessible. Filing fees are modest ($102 for claims over $2,500 filed electronically).
  • For amounts over $35,000, consult a litigation lawyer. Many offer free initial consultations. Gather your evidence file before the consultation to make the meeting productive.
  • Before investing in litigation, consider whether the contractor has identifiable assets. A judgment against a dissolved numbered company with no assets is not worth the legal fees. A lawyer can advise on the likelihood of collection.
  • Check whether your home insurance covers any portion of the loss. Some policies have limited coverage for contractor fraud or faulty workmanship. Review your policy or call your insurer to ask.

Important

  • Time limits apply. The Ontario Limitations Act generally provides a two-year window from when you knew or ought to have known about the issue. Do not delay in seeking legal advice if the amount involved is significant.

🏁 9. Final Word from Aldo Homes {#9-final-word-from-aldo-homes}

The uncomfortable truth is that Ontario’s regulatory framework places the burden of protection disproportionately on homeowners. There is no licensing body for renovation contractors. There is no government-backed warranty for renovation work. And there is limited enforcement capacity for the protections that do exist. The nine gaps we documented in Part 2 of this series are not theoretical — they are the specific openings that fraudulent contractors exploit, repeatedly, across the province.

This is not a reason to avoid renovating your home. Home improvement is often necessary, and when done well, it adds value to your property and quality to your life. But it is a reason to approach every project with the same diligence you would apply to any major financial decision — because that is exactly what a renovation is. A $50,000 renovation deserves at least the same scrutiny you would give to buying a $50,000 vehicle.

The single most effective protection is not a law or a government program — it is your own informed, methodical vetting process. The extensive steps described in this checklist are not burdensome. They are the cost of operating in a system that does not yet do enough to protect you. Every step you complete reduces your risk. Every step you skip is a gap that a dishonest contractor can exploit.

At Aldo Homes, we believe that transparency is the foundation of trust. We publish this guide — and the entire Homeowner Protection Series — because homeowners deserve to understand not just the protections that exist, but the gaps in those protections. An informed homeowner is the most effective defence against contractor fraud. If you have questions about your renovation project or want to learn more about how Aldo Homes operates, contact us directly. We welcome the scrutiny — because legitimate contractors have nothing to hide.

❓ FAQ

1. Why is defining the scope of work so important?Because it ensures every contractor is quoting the same work, making comparisons accurate and preventing vague or misleading estimates.
2. Why should homeowners research permit requirements themselves?Because contractors may incorrectly claim permits aren’t needed, municipalities vary, and unpermitted work can cause fines, insurance issues, and resale problems.
3. Why are dramatically low quotes a red flag?They often indicate corner-cutting, skipped permits, cheap materials, or planned cost inflation through change orders.
4. Why must homeowners search the contractor’s personal name?Because fraudulent contractors frequently dissolve and reopen numbered companies; only personal name searches reveal litigation history.
5. Why is verifying insurance directly with the insurer necessary?Because expired or falsified insurance documents are common in contractor fraud cases.
6. Why is a detailed written contract nonnegotiable?Because verbal agreements are unenforceable, and written terms determine your ability to recover losses if something goes wrong.
7. Why is the 10% holdback required?Because the Construction Act mandates it to protect homeowners from liens filed by unpaid subcontractors and suppliers.
8. Why should homeowners never pay in cash?Cash eliminates the paper trail needed for legal action and may involve tax evasion, increasing homeowner liability.
9. What should homeowners do immediately after realizing they’ve been scammed?Stop payments, document everything, secure the property, and begin reporting to relevant authorities.
10. Why does the Limitations Act matter?Because homeowners generally have two years to take legal action from the moment they knew or should have known about the issue.
