How to find a general contractor in the GTA without getting burned

Hiring the wrong contractor is the most expensive mistake a homeowner makes during a renovation. Hiring the right one is the cheapest way to make the rest of the project go well. The interview is where the difference is decided.

What "licensed" actually means in Ontario

There is no general contractor license in Ontario. None. A contractor cannot put "licensed general contractor" on their truck because no such credential exists in this province. What exists are these:

• Trade-specific licenses. Electricians need an ECRA/ESA license. Plumbers need a Master Plumber license through the Ontario College of Trades. Gas fitters, sheet metal, refrigeration — each has its own.
• Municipal business licenses. The City of Toronto requires a business license for renovation contractors, which is mostly an administrative registration.
• HCRA. The Home Construction Regulatory Authority licenses new home builders, not renovators. If you are doing a new build, the contractor needs HCRA registration. If you are doing a renovation, this does not apply.
• WSIB. Workplace Safety and Insurance Board coverage is mandatory for any contractor with employees. A WSIB clearance certificate confirms current coverage.
• Insurance. Liability insurance is not legally required but is a baseline expectation. Ask for the certificate of insurance on the contractor's letterhead showing coverage limits in force for the project dates.

When a contractor says "we are fully licensed and insured," ask for what specifically. The answer is usually: a municipal business license, WSIB coverage, and a liability policy. That is the floor, not a credential.

The seventeen questions

Have these on a printed list. Ask all of them. Take notes.

1. How long have you been operating under your current business name?
2. Are you a corporation, a sole proprietorship, or a partnership?
3. Can I see your WSIB clearance certificate dated this month?
4. Can I see your liability insurance certificate, and what is the coverage limit?
5. Who will be the project lead on my job, and how many active projects will they be running concurrently?
6. Will subcontractors be used, and which trades will be in-house versus subbed?
7. Can I see three written references from projects completed in the last 18 months that are similar in scope to mine?
8. Can I visit a current jobsite of yours this week?
9. How are change orders priced, documented, and approved?
10. What is your payment schedule, and what triggers each payment?
11. How is the holdback handled at substantial completion?
12. What warranty do you offer in writing on workmanship and on materials?
13. How do you handle delays caused by your trades versus delays caused by my decisions?
14. Will the project lead be onsite daily, weekly, or as-needed?
15. How do you handle dust containment and protection of finished surfaces?
16. What is the dispute resolution process if we disagree on completed work?
17. Can I see the actual contract template you would propose?

The answers tell you a lot. The willingness to answer tells you more.

The red flags

A contractor who exhibits any of these should not be your contractor.

• Cash discounts. "We can save you the HST if you pay cash." This is illegal tax evasion that exposes you to liability if the CRA audits. It also tells you the contractor is willing to defraud the federal government, which raises questions about how they will handle your money.
• No written quote. If the price is verbal, it is not a price. It is an estimate that will be revised.
• Quote significantly below the others. A quote 25 percent below the next-cheapest is not a deal. It is missing line items that will reappear as change orders.
• No fixed payment schedule. "Pay as we go" or "pay when I ask" gives the contractor unilateral control of cash flow with no completion milestones to anchor it.
• Large deposit demand. Industry standard for a renovation is 10 to 15 percent on signing. A 40 percent deposit before any work has started is a major flag.
• Refusal to pull permits when permits clearly apply. See our permits piece for what triggers a permit.
• No WSIB coverage. If a worker gets injured on your property and the contractor is not WSIB-covered, you are personally exposed to the medical and disability claims.
• Pressure to sign quickly. "This price is only good for 48 hours" is a sales tactic, not a project condition.
• Vague references. "I can give you references but most of my clients are private and don't want to be contacted." Real contractors have a reference list of clients who consented to be called.

Any one of these is a serious flag. Two together is a hard pass.

How references actually work

Most homeowners ask for references and never call them. Of those who call, most ask "how was your experience?" and accept a vague positive answer. That is not reference checking; that is reference theatre.

Here is what to actually ask the reference:

• What was the original quoted price and the final paid price? A delta of more than 10 percent is a flag on the contractor's quoting accuracy.
• Was the project completed on the original schedule? If not, what was the delay and whose decision drove it?
• Were there change orders, and how were they documented and priced?
• What surprised you, good or bad, during the project?
• Was the project lead reachable and responsive during the work?
• Has anything failed or required follow-up in the time since?
• Would you hire them again for a different project? Why or why not?

Visit one current jobsite if the contractor will allow it. Five minutes on an active site tells you more than an hour at a finished one. Look at dust containment, material storage, the apparent organization of the trades, the cleanliness of cuts, the way the temporary services are run. If a site looks chaotic, the project running on it is likely chaotic too.

Quotes — how to compare them

Get three written quotes. Insist they be itemized in the same format so you can compare line items, not bottom-line numbers. The cheapest quote is almost never the cheapest project, because the gap between the cheap quote and the realistic quote becomes change orders mid-job, when you have no leverage.

Specifically compare:

• Demolition and disposal. Some quotes leave this off entirely.
• Permit fees and the contractor's time managing inspections.
• Electrical and plumbing rough-in scope, in detail.
• Waterproofing assembly in any wet area, by name (Kerdi, Wedi, Hydro Ban, etc).
• Finish allowances. A "tile allowance of $3/sq ft" means the contractor is assuming builder-grade tile. If you want stone porcelain at $12/sq ft, that gap is yours to fund.
• Project management and supervision time, broken out separately.

A quote that is 20 percent above the others, but covers items the others omit, is often the actual cheapest project.

Contracts — what should be in writing

The signed contract should include scope (with drawings or specs), price (with payment schedule), schedule (with start and substantial completion dates, plus what triggers an extension), change order procedure (in writing, signed before work proceeds), warranty terms, holdback handling, dispute resolution, and termination terms. Anything verbal between you and the contractor is unenforceable. Get it written.

What to do next

Interview at least three contractors using the question list above. Visit at least one current jobsite. Call at least two references per contractor and ask the actual diagnostic questions, not the polite ones. Get three itemized quotes and compare line items. The whole interview process takes three to five weeks. Spending that time saves months of trouble during the build.
