7 questions to ask before hiring a general contractor in Toronto
Why these seven questions matter for Toronto projects
Choosing the right general contractor for a commercial build-out or a residential renovation in the Greater Toronto Area affects cost, schedule, code compliance, and final finish quality. A single contractor commonly coordinates multiple trades, arranges permits, and manages inspections. Deeroi Constructions asks for the project address, scope, and deadline so bids are comparable and the team can plan trades and produce a clear construction path. Use that intake as a model when you request quotes so each bidder prices the same brief (Deeroi Constructions).
This article lists seven specific checks to use in interviews and proposals. For each item you will get the exact question to ask, a responsible answer to expect, and the warning signs that should prompt follow up or disqualification.
7 questions to ask before hiring a general contractor Toronto
1. Who is the constructor on this project and who will pull permits
Question to ask: "Will your company act as the constructor and will you pull permits in your name?"
What to expect: In Ontario, when an owner hires a single contractor to perform all work, that contractor is the constructor and remains responsible for the project even if work is subcontracted. Ask the bidder to confirm in writing that they will take constructor responsibility and to name who will apply for and manage municipal permits (Constructor guideline | ontario.ca).
Warning signs: A contractor who insists permit responsibility belongs to the owner but cannot explain how inspections will be scheduled or who will attend them. Unclear permit ownership can lead to missing inspection records and gaps in site-safety accountability.
2. Is the estimate a fixed price or an allowance-based bid
Question to ask: "Is this a fixed-price quote for the full scope, or are there allowances and provisional sums? Can you itemize them?"
What to expect: A responsible estimate separates defined scope items from allowances for finishes, appliances, or equipment. It shows unit pricing and provisional sums so you can compare bids on the same basis and see where costs may vary.
Warning signs: One-line totals with few line items, vague allowances described as "to be selected later," or no contingency. Those formats often make change orders the default route for routine decisions and hidden costs.
3. How will change orders be handled and priced
Question to ask: "Show me your change-order form and explain the approval, pricing, and timing process for changes after work starts."
What to expect: A clear change-order workflow: a written request, agreed price or transparent rate, client sign-off, and schedule adjustment. Reputable contractors supply a sample form and explain common triggers for extras such as site conditions, millwork revisions, or finishing selections.
Warning signs: Verbal promises about extras or refusal to show a sample change-order form. That gap often leads to disputes about scope and unexpected invoices.
4. Who are the key subcontractors and can you share recent references and photos
Question to ask: "Who will do the millwork, electrical, plumbing, and waterproofing? Can you provide references and recent photos of similar projects?"
What to expect: A named list of primary subcontractors, contactable references, and recent project photos showing the finished quality. For restaurant build-outs or bank renovations, expect close-up images of millwork joints, counter returns, and integrated lighting that demonstrate finish quality.
Warning signs: Generic claims that trades are "trusted" without names, or a portfolio that lacks projects similar to your scope. If finish quality matters, ask explicitly for photos of details such as tile waterproofing and millwork returns.
5. What is the proposed schedule and how will trade coordination be managed
Question to ask: "Provide a preliminary schedule with major milestones and explain how you will coordinate trades to keep the sequence on track."
What to expect: A milestone-based schedule that lists start date, major trade windows, inspection milestones, and a short description of coordination practices: who runs site meetings, how delays are raised, and how long lead items are managed.
Warning signs: Only a vague completion target such as "6 to 8 weeks" without milestones, or a contractor who blames delays on external factors without describing mitigation steps. Commercial build-outs require close sequencing of millwork, electrical, mechanical, and finishes.
6. What insurance, WSIB, and safety documentation will you provide
Question to ask: "Can you show proof of liability insurance, applicable WSIB clearance or equivalent, and your jobsite safety plan?"
What to expect: Copies of insurance certificates showing project limits, WSIB clearance or account details where applicable, and a concise safety and site-cleaning plan. If the contractor will act as constructor, they should describe site safety coordination, supervision, and daily housekeeping routines.
Warning signs: Hesitation to share insurance or WSIB documentation, or noncommittal answers about safety. Those gaps increase exposure to liability, stop-work orders, and inspection issues.
7. How do you document scope, quality standards, and final acceptance
Question to ask: "How will you record the agreed scope and quality standards and what is your final acceptance process for practical completion?"
What to expect: A written scope of work referenced by the contract, a finish checklist or photographic schedule for key items, and a practical completion walk-through with a punch list and sign-off procedure. This approach reduces disagreements about what was promised versus what was delivered.
Warning signs: Reliance on verbal assurances for finish standards or no formal acceptance and punch-list process. Without documented acceptance, owners often accept substandard items or face disputes when releasing retainage.
How to compare bids and spot hidden costs

When you receive multiple estimates, use this quick checklist:
- Scope clarity: Does each bid describe the same work and exclusions?
- Allowances and provisional sums: Are they clearly itemized and priced?
- Unit pricing: Are rates listed for doors, tiles, labour and other common change items?
- Contingency and schedule risk: Is a contingency included and is the schedule realistic?
- Payment milestones: Are deposits and milestone payments tied to deliverables?
- Trade coordination detail: Does the contractor explain sequencing and lead-time management?
Rank bids by documented scope, portfolio fit, trade coordination plan, and schedule confidence rather than lowest price alone. A low bid with a vague scope frequently becomes the most expensive once allowances and extras are added.
Ontario permits, constructor responsibility, and inspections
Ontario guidance states that when an owner hires only one contractor to do all the work, that contractor is the constructor and is responsible for site safety, coordination, and compliance even if subcontractors perform the work. Confirm in writing who will sign permit applications, schedule inspections, and represent the project to municipal authorities (Constructor guideline | ontario.ca).
Treat any refusal to accept constructor responsibility as a major decision risk. Permit ownership determines who manages inspections, code questions, and interactions with municipal building officials.
Common owner objections and reasonable contractor responses

Price is too high: A reliable contractor will break the estimate into high-cost items, propose value-engineering options, and explain tradeoffs rather than simply reducing material quality.
Request for a guaranteed finish date: Contractors can contract to milestones or liquidated damages in some arrangements, but a reasonable commitment will include contingencies for supply delays and inspections rather than an absolute, unconditional guarantee.
Desire to hire cheaper subs directly: Expect the contractor to vet or refuse unvetted subs. If a contractor will not coordinate and guarantee subcontracted work, quality and warranty gaps commonly follow.
Documents to request before you sign and keep during the project
Ask for and keep copies of these items:
- Detailed scope of work and the written contract
- Line-item estimate with allowances and contingency
- Payment schedule and milestone definitions
- Sample change-order form and approval workflow
- Insurance certificate and WSIB or equivalent documentation
- List of key subcontractors and recent references with photos
- Site safety plan and daily site-cleaning expectations
- Punch-list and practical completion acceptance form

Frequently asked questions
Do I need a building permit for a commercial build-out in Toronto and who pulls it
Most commercial build-outs need permits. The contractor acting as constructor will usually apply for and manage permits. Confirm who will pull permits and which inspections the contractor will handle.
What does it mean that the contractor is the constructor under Ontario rules and why does it matter
Under Ontario rules the constructor is legally responsible for safety, coordination, and compliance even when work is subcontracted. That status affects who signs permits, schedules inspections, and enforces site safety (Constructor guideline | ontario.ca).
What should be included in a detailed construction estimate for a restaurant or retail fit-out
An effective estimate lists the full scope, itemized finishes, allowances, provisional sums, unit pricing, contingency, and a milestone payment schedule. For restaurants expect separate line items for millwork, bar counters, lighting packages, and mechanical adjustments.
How can I verify a contractor's recent work and confirm finish quality before hiring
Request recent project photos and contactable references, and ask for close-up images of critical details such as millwork joints, tile waterproofing, and counter returns. If possible, arrange a timed visit to a current site to see trade coordination and cleanliness firsthand.
