Most homeowners spend the first contractor conversation asking about price and finish options, then find out the things that actually mattered, who was really on site, who pulled the permit, who answers the phone once the invoice is paid, only after something's already gone wrong. Our own about page puts it plainly: if you're comparing contractors, ask the same questions you'd ask anyone else, "who is actually on site, who pulls the permit, and who you call if something needs fixing after the job is done." That's not a sales line, it's the actual filter worth running before a deposit changes hands.
This list is the proactive half of that filter. If you want the warning signs that mean walk away, our red flags to watch for when hiring a renovation contractor covers that side. This piece is the opposite angle: the specific questions worth bringing to a first conversation with anyone you're considering, ours included, and what a straight answer actually sounds like versus a dodge. It rounds up the questions our own complete guide to choosing a renovation contractor in Ontario touches on piece by piece, in one list you can actually use.
Key Takeaways
- Who's physically on your job site, and whether that's the same person from the first measure to the final walkthrough, tells you more than almost any other question you can ask.
- "Licensed and insured" only means something once you ask which licence, for which trade, and see the WSIB and liability paperwork yourself rather than taking the phrase at face value.
- A deposit over 10% or a payment schedule that isn't tied to completed work is worth a follow-up question, not an automatic disqualifier, but it is worth asking about directly.
- The single question that separates a contractor worth hiring from one that isn't: who do you call if something needs fixing six months after the crew has left.
1. Who will be on my job, and is it the same crew throughout?
Ask this before you ask about price. Some renovation companies run one crew, in-house trades or long-term partners who work the same jobs together and answer to the same project manager, from the first measure to the final walkthrough. Others sell the job in a sales meeting, then hand it off to whichever subcontractors are free that week, with no one person accountable for how the framing, the plumbing, and the tile actually line up. That difference is invisible in a glossy quote and very visible the first time you have to re-explain your own project to a tradesperson who's never seen the drawings.
A straight answer names a specific person and describes how long that person has worked with the crew doing the physical labour. A dodge sounds like "we'll figure out who's available." This matters more on a job with real trade coordination, a concrete driveway in Kitchener depends on the crew pouring the slab understanding the same subgrade compaction and drainage plan the estimator specified, not learning it fresh on pour day from a printed sheet.
2. Can you show me your licence and insurance, not just mention it?
Ontario doesn't licence general renovation contractors as a category, but specific trades inside your project, electrical, gas, plumbing, absolutely are regulated, and "insured" actually covers two separate things: liability insurance for property damage and WSIB coverage for worker injuries. Neither one should be a verbal claim you have to take on faith. A WSIB clearance certificate is free to look up directly on WSIB's own site, and a legitimate electrical subcontractor's licence number checks against the Electrical Safety Authority's public contractor search in under a minute.
A good answer hands you a certificate number or a licence number without hesitation, because it's paperwork the contractor already has on file for every job. Our full breakdown of what "licensed and insured" actually means goes through exactly which credential covers which part of a renovation, since the phrase alone tells you almost nothing until you know what to ask for specifically.
3. Who pulls the permit, and what if an inspection flags something?
Either the homeowner or the contractor can be the named applicant on a building permit in Ontario, but that choice doesn't change who's legally on the hook if the work goes ahead without one. It's still the property owner. That makes this question worth asking directly rather than accepting "don't worry, we'll handle it" as a full answer. Ask who applies, when the application actually gets submitted relative to the deposit, and who's responsible for booking the inspections along the way.
This comes up constantly on work that pulls in a real permit review, a basement renovation in Toronto that adds a legal secondary suite needs its own residential-unit permit on top of the interior-alteration fee, and skipping that step doesn't just risk a fine, it risks a rental unit that was never legally created in the first place. Our guide to who's actually responsible for pulling permits walks through what should be in writing before anyone breaks ground.
4. What's the payment schedule, and how much is due upfront?
A deposit itself isn't a warning sign. The size and the timing are what tell you something. Ontario's own consumer protection guidance points to keeping a deposit around 10% of the contract price, tied to a written, itemized quote that already exists, not a number requested before any scope has been agreed on paper. A payment schedule that's staged to actual milestones, framing complete, rough-in passed, final walkthrough, protects you if a job stalls partway through. A single large sum upfront doesn't.
Ask for the schedule in writing before you ask about the total price. Our guide to deposit and payment schedules that are normal in Ontario covers the specific structure worth expecting and the patterns that should make you pause.
5. Is the price fixed, and what happens when a wall comes open?
A one-line total, "kitchen renovation: $42,000," tells you nothing about what's actually included, and it's the format most likely to grow once the crew starts. An itemized quote breaks out materials, labour, permits, and cleanup separately, so you can see exactly what you're paying for and compare it apples-to-apples against a second contractor's number for the same scope.
Just as important is what happens when the estimate meets the real house. Ask specifically how change orders get handled if something turns up that the quote couldn't have caught, old wiring behind a wall, rot under a subfloor. A contractor who documents the specific unforeseen condition, prices only that piece, and asks for your written approval before doing the extra work is a different experience than one who treats every surprise as an opening to renegotiate the whole job. Our comparison of an itemized quote versus a low price covers why the cheapest number on paper is often the most expensive one by the time a project actually finishes.
6. What's the realistic timeline, and what happens if it slips?
Ask for an actual start date and completion date, not "a few weeks," and ask what happens to your schedule and your budget if the project runs long. Some delays are outside anyone's control, a material backorder, a failed inspection that needs a re-do. What matters is whether the contractor communicates a slip as soon as they know about it or lets you find out when the crew simply doesn't show up on the day you expected them.
A kitchen or bathroom typically runs two to four weeks once work starts; a basement or a legal secondary suite runs six to ten, since that scope pulls in framing, electrical, plumbing, and egress review on top of the finish work. If a quote for that kind of project comes back with a timeline dramatically shorter than that range, ask what's being skipped to hit it.
7. Can I read the contract first, and does it match what we agreed?
A verbal understanding is not a contract, and in Ontario any home renovation agreement worth more than $50 is legally required to be in writing. What matters beyond that legal minimum is whether the document you're handed actually reflects the conversation you had: the scope described specifically rather than in vague allowances, materials named by brand and model, the payment schedule, the warranty terms, and who's responsible for permits, all spelled out in the text rather than promised out loud and left off the page.
Take the contract home and read it fully before you sign, and treat any pressure to sign on the spot as its own answer to this question. Our section-by-section walkthrough of how to actually read a renovation contract covers what each part should say and the vague language worth pushing back on.
8. What warranty do you offer on the actual workmanship, in writing?
There's no government-backed warranty program standing behind a renovation the way Tarion stands behind a new home, which means whatever protection you have after the crew leaves comes entirely from what your contractor put in writing. Ask specifically about workmanship, the labour itself, separately from a manufacturer's product warranty on materials, since those are two different documents on two different clocks, and losing track of which one covers a specific problem is the most common mix-up homeowners run into after the fact.
Ask to see finished examples of the same kind of work somewhere in your area, not just fresh installation photos. A flooring installation in Hamilton that's a year or two old and still tight at the seams tells you more about a contractor's actual workmanship than a portfolio shot taken the week it was finished. Our guide to warranty expectations for renovation and concrete work covers what's typical to ask for and how concrete and interior finishes tend to be warrantied differently.
9. Can I talk to recent clients and see reviews you didn't pick?
Anyone can hand you two happy customers. What's harder to fake is a broad, recent, and specific track record, project photos beyond a handful of staged shots, and reviews that weren't curated for the sales conversation. The Better Business Bureau's guidance on hiring a general contractor recommends asking for references from work similar to your own project and following up on them directly rather than treating a short list on a sales sheet as sufficient. Ask for references from the last year, not just the ones a contractor is proudest of, and ask what a legitimate reviews page actually looks like before you take a testimonial on a website at face value.
We keep our own client feedback public rather than filtered for a pitch. Our reviews page has the unedited version, project by project, and it's worth reading before you sign with us or with anyone else you're comparing against.
The one question that sums up all the others
If a contractor answers every question above clearly, without hedging, there's usually one underlying thing they've already told you: who you can actually call if something needs fixing after the job is done. That's the question our own about page tells people to ask us directly, because the answer shouldn't change between the first conversation and the final walkthrough. A contractor who's vague about who's on site, who pulled the permit, or what the warranty covers is usually being vague about that last question too, whether they say so out loud or not.
Frequently asked questions
Is it rude to ask a contractor for licence and insurance proof before hiring them?
No, and a legitimate contractor won't treat it that way either. Asking to see a WSIB clearance number or an electrical subcontractor's licence is a five-minute check that protects you if something goes wrong, and it's a request contractors field regularly. A contractor who bristles at the question, rather than simply producing the number, is telling you something more useful than the number itself would have.
How many of these questions should I ask in the first conversation versus save for later?
Ask about crew structure, licensing and insurance, and the payment schedule in the first conversation, before a deposit is discussed seriously. Permits, warranty terms, and the exact change-order process can wait until you're comparing a written quote, since those answers are easier to evaluate once you have something on paper to check them against. Either way, get every one of these answers in writing eventually, not just spoken out loud.
What if a contractor gives good answers verbally but the written contract says something different?
Trust the document, not the conversation. If a contract omits a warranty term, a permit responsibility, or a payment schedule detail that was promised verbally, that gap is the actual risk, regardless of how the sales conversation went. Ask for the contract to be corrected before you sign rather than assuming the verbal promise still applies once there's a signature on the page.
Should I ask these same questions if I'm only doing a small project, like a single room?
Yes, scaled to the job. A small painting or flooring project doesn't pull in the same permit or licensing questions a basement renovation does, but the payment schedule, the warranty, and who's actually on site still apply at any size. The scope of the questions shrinks with the project; the need to ask them doesn't.
