The Homeowner’s Guide to Hiring a Contractor Without Getting Scammed in Canada
Hiring a contractor is a significant decision. For many homeowners, the process is filled with a sense of apprehension and a legitimate fear of being taken advantage of. Whether it’s an unexpected vehicle repair bill or an undisclosed fee on a major project, the risk of financial misdirection is a common concern. You want to feel confident that your investment will result in outstanding service and a high-quality finished product.
This level of concern is particularly acute when planning a new roof or siding project. Your home’s exterior is its primary defense against Canada’s diverse and often harsh climate. The sheer number of roofing and siding companies can be overwhelming, leaving homeowners uncertain about who to trust.

While the home services industry, like any other, has its share of unethical practitioners, a greater number of highly professional and reliable contractors exist. The key to a successful project lies in a vigilant and informed approach to vetting potential companies. This guide provides a comprehensive 9-point checklist designed to empower you. By following these steps, you can protect your investment and ensure your exterior renovation is completed to the highest standards.
Your 9-Point Contractor Vetting Checklist
To ensure your project is a success, you need to go beyond a simple quote. Here are the nine essential points you must check before signing any agreement.
1. Proof of Insurance
A reputable contractor should carry a liability insurance policy, typically with coverage between $2 and $5 million. This isn’t money sitting in a bank account; it’s a guarantee from an insurance company that they will cover damages if the contractor is found liable for an accident. For example, if a roofer accidentally drops a piece of equipment and puts a hole in your siding, or if a ladder falls and damages your neighbor’s property, the policy covers the cost of repairs. Without this insurance, you could be left to pay for the damages out of your own pocket. To be safe, always request a Certificate of Insurance directly from the contractor’s insurance provider—this document proves the policy is active and valid.
2. Business Registration
A contractor must be a legitimately registered business in your province or territory. This is a crucial sign of a legitimate, long-term operation, not a “fly-by-night” crew. Registration shows they are a real company with a verifiable address, a legal name, and a public record. It means they’re accountable and can be located if something goes wrong. You can often verify a business’s registration status by searching on your provincial government’s corporate registry website.
3. Workers' Compensation
In every province and territory in Canada, contractors are required to be registered with a Workers’ Compensation Board (WCB), such as WSIB in Ontario or WorkSafeBC. This mandatory insurance program protects workers who are injured on the job. If a worker gets hurt on your property and the contractor doesn’t have proper coverage, you, the homeowner, could be held personally liable for the worker’s medical bills, lost wages, and rehabilitation costs. A valid, clean clearance certificate proves that the contractor is registered and their account is in good standing, transferring all liability away from you.
4. Positive References

Don’t just take their word for it—get at least three confirmed, satisfied homeowners to vouch for their work. A reputable contractor should be happy to provide you with a list of recent clients you can contact. Speaking directly with past customers can give you insight into the contractor’s professionalism, communication, quality of work, and ability to stick to a timeline.
5. Clean Reputation
A clean reputation is a sign of a trustworthy business. Search for the contractor’s name and company online. Look for any unresolved complaints, disputes, or legal issues with the Better Business Bureau or other consumer review platforms. While one negative review isn’t necessarily a red flag, a pattern of unresolved complaints should be a major concern.
6. Portfolio of Recent Work
Ask to see a portfolio of recent work. Verified before-and-after photos from recent projects show that the contractor has a consistent track record of quality. A solid portfolio demonstrates their experience and ability to successfully complete projects similar to yours.
7. Safety Requirements
Professional contractors prioritize safety. They should be able to confirm that they follow all mandated safety protocols, including the use of fall arrest systems and proper training like WHMIS (Workplace Hazardous Materials Information System). Their adherence to safety standards not only protects their workers but also shows a commitment to professionalism and a reduced risk of on-site accidents.

8. Detailed Written Estimates
A reputable contractor will provide a clear, itemized quote. This isn’t just a simple number; it should contain a detailed scope of work, a list of materials, and a clear timeline for the project’s completion. A detailed estimate prevents unexpected costs and ensures complete transparency before the work begins.
9. Signed Service Agreement
Never proceed without a signed service agreement. A written contract protects both you and the contractor. It should clearly outline the scope of work, the agreed-upon price, the payment schedule, a start and end date, and any warranty information. A professional contract ensures accountability and provides a legal reference in case of any disputes.
