How to Choose a Renovation Contractor in Toronto: 7 Questions to Ask Before You Sign

This is the single most important question and the easiest to verify. In Ontario, any contractor doing work above a basic handyman level should carry general liability insurance (typically $2 million minimum) and have active WSIB coverage for their crew. If a worker gets injured on your property and the contractor has neither, the liability lands on you as the homeowner.

• Ask for proof of insurance — a real PDF certificate, not a verbal assurance.
• Verify WSIB clearance directly at wsib.ca with the clearance certificate number.
• Confirm any trades performing licensed work (electrical, gas, plumbing) hold the appropriate ECRA/TSSA licences.

A contractor who cannot produce these documents within 24 hours is not someone you want building inside your home — full stop.

Photos on a website are useful, but visiting a recent project in a comparable building or neighbourhood is much more revealing. Contractors who do a lot of work in Toronto and GTA should be able to point you to recent projects in Etobicoke, Oakville, Mississauga, Thornhill, North York, or Midtown — wherever your project is located.

• Ask for a portfolio with addresses (or general neighbourhoods) and dates.
• Request 2–3 references for projects completed within the last 12 months.
• If possible, visit a project in person to see finish quality up close, not just in photos.

This question separates renovation companies into two very different operating models. In-house crews are employed by the company, work together long-term, and the company is directly accountable for their work quality. Subcontracted crews are hired per project from a pool of available trades.

• In-house crews — more consistent quality, single point of accountability, smoother communication, fewer scheduling gaps.
• Subcontracted crews — more capacity for large projects, but quality varies and trades may juggle multiple jobs.
• Hybrid models — some companies have a core in-house team plus specialty subs (e.g., custom cabinetry); reasonable if managed well.

There is no universally right answer, but you should know which model you are buying into before you sign. We work with full-time in-house crews with 30+ years of combined experience.

Quotes that come back as a single number are almost always missing scope. A reliable renovation contractor in Toronto will provide an itemised quote that explicitly lists every category of work.

• Demolition and debris removal
• Plumbing rough-in and final connection
• Electrical rough-in and final connection
• Waterproofing (for wet areas)
• Drywall, framing, and painting
• Tile install (square footage specified)
• Fixtures, vanities, and hardware (allowance or specific products)
• Final cleaning and walkthrough

If any of these categories is missing or vague ("includes finishing"), ask for clarification in writing. A clear scope protects both sides and prevents the change-order surprises that wreck renovation budgets.

Realistic timelines for typical Toronto and GTA renovations: a 3-piece bathroom = 2–4 weeks, a full kitchen = 4–8 weeks, a full home renovation = 12–20+ weeks. Any contractor quoting half these timelines is either over-promising or planning to compromise quality.

• Ask for a written timeline with major milestones, not just a start and end date.
• Discuss what triggers delays (material backorders, condo board approvals, scope changes) and how they are handled.
• Confirm whether the contractor takes on multiple concurrent projects — if so, ask how your project is staffed.

Renovations rarely finish on the original day. A contractor who is upfront about realistic timelines and how they manage slippage is more trustworthy than one who promises an aggressive deadline you both know will slip.

Payment structure is one of the strongest signals about contractor reliability. Reasonable structures tie payments to milestones, not calendar dates.

• Deposit (10–25%) before work begins
• Progress payments tied to specific milestones (demolition complete, rough-in inspected, tile installed)
• Holdback (10–15%) released after final walkthrough and deficiency list resolved

Avoid contractors asking for 50%+ upfront, weekly draws regardless of progress, or cash-only payment. Those structures protect the contractor against your worst-case but expose you to theirs.

A renovation generates dozens of decisions per week — tile choice, fixture pick-ups, schedule changes, deficiency call-outs. You need to know exactly who you talk to and how quickly they respond.

• A single named project manager or owner who is reachable during business hours.
• A clear communication channel (phone, email, or a project management app like Buildertrend or CompanyCam).
• Expected response time for non-urgent questions (24 hours is reasonable; 72+ is not).

Renovation problems multiply when communication is unclear. A contractor who is hard to reach during the sales process will be impossible to reach mid-project.
