This question is non-negotiable. Ask for both documents before the conversation goes any further.
A qualified contractor can arrange current certificates quickly. Best practice is to have the insurance certificate sent directly from the contractor’s broker, not as a photocopy, and to verify WSIB clearance yourself online. Both checks are free and take minutes. If a contractor stalls or makes excuses, move on.
Permits protect you. They ensure structural, electrical, plumbing and mechanical work is reviewed and inspected before it is closed up behind walls and ceilings. Work that fails inspection must be corrected, sometimes by reopening finished surfaces. Unpermitted work discovered at resale can lower your sale price, trigger conditional offers or derail the transaction. The answer should be specific. A knowledgeable contractor can tell you right away which approvals your project needs and why:
A contractor who says permits are unnecessary when they clearly apply, or suggests skipping them to save time and money, is telling you how they will approach the rest of your project.
| At Maple Leaf Quality Renos, we manage all permits and approvals in-house on every project, and we never begin construction without them in hand. |
Many renovation contractors act as project managers and subcontract the trades. That is not a problem in itself, but it becomes one when subcontractors are unlicensed, unvetted or working without direct oversight. Ask specifically:
In Ontario these are legal requirements, not preferences. Unlicensed electrical work is a serious fire risk, and improper plumbing can cause major water damage and resale problems. A qualified contractor names the trades, their licences and how they are supervised. Vague talk about an "experienced team" or "trusted guys" does not answer the question.
A professional renovation estimate is not a single number. It is a written document listing every part of the scope: materials (by brand and grade where it matters), labour, explicit exclusions, permit costs, timeline and payment schedule, with each line priced separately. Vague estimates are one of the most reliable warning signs in the GTA. A low, single-line number wins the job, then grows during construction as scope additions, upgrades and hidden conditions are added to the invoice, long after you can realistically walk away. If a contractor cannot or will not itemize the scope, their pricing will be impossible to manage once work begins.
A professional payment schedule is tied to completed milestones, not dates. A reasonable structure starts with a modest deposit at signing, with the balance released as defined stages are completed, such as demolition, framing and rough-ins, and a final payment at handover.
Be immediately concerned if a contractor asks for cash or offers a cash discount. Cash-only requests are not about convenience. They remove your ability to document what you paid, when and for what.
References are among the most reliable signals of contractor quality. Ask for three recent clients with projects similar to yours, with real contact information, not testimonial screenshots or review links. When you call, ask:
A contractor with a strong track record has clients happy to talk. One who cannot provide three reachable references has work that cannot withstand examination.
Communication breakdown is one of the most common sources of renovation stress. A contractor who is responsive during the estimate and hard to reach once construction starts is a familiar pattern. Before signing, confirm:
A contractor with a structured process can describe it clearly. One without will offer vague promises of being "always available."
Your renovation contract is the legal document that protects you if something goes wrong. Before you commit, confirm it includes:
A one-page letter, vague scope or verbal agreement leaves you exposed, and in renovation, unexpected situations almost always arise. Never let construction start without a signed, detailed contract in hand.
A workmanship warranty is the contractor’s written commitment to correct defects in their work at no cost within a set period after completion. In the GTA, one to two years is standard. It is separate from manufacturer warranties on products and covers the quality of the installation itself. Ask what it covers, what it excludes and how claims are handled. A written warranty with a clear claims process shows confidence in the work. "We’ll come back if anything goes wrong" is not a warranty.
Most homeowners never think to ask this, and it is one of the most revealing questions of all. A contractor who has truly managed projects like yours can speak confidently about the technical requirements. For example, ask:
You do not need to know the answers. Listen to how they respond. A knowledgeable contractor answers directly, explains the reasoning and welcomes the conversation. One who does not know deflects, offers vague reassurance or steers back to price. Technical confidence is evidence of experience.
A contractor who answers all 10 questions clearly and specifically is worth taking seriously. Request the written estimate, review the contract, call the references and verify insurance and WSIB before you sign or pay anything. A contractor who struggles, deflects or gets defensive when pressed is showing you how they will manage your project once they have your deposit.
