Two renovation quotes can be thousands of dollars apart and describe different jobs. Before comparing totals, put them beside each other and check what you would receive at completion. Disposal, electrical notifications, wall repairs, hardware, and tax are easy to overlook. The Ontario renovation HST guide helps you check that last line. Ask the awkward question before signing. It gets more expensive afterward.
This guide is practical information, not legal advice. For a large or unusual project, Ontario itself recommends having a lawyer review the contract. The province's current home-renovation consumer guide is the right official starting point.
The five-minute top-line test
A first pass takes five minutes. Before comparing cabinet brands or tile allowances, check these five items. If a quote fails one, send it back for revision.
- Identity: Is the contractor's legal or operating name, physical address, phone number, and email shown? Does the name match the entity taking your deposit?
- Scope: Can you point to a written description of the finished result, not merely a list of verbs such as demo, frame, finish?
- Total: Does the number clearly say whether applicable taxes are included? Is the payment currency obvious?
- Time: Are there proposed start and completion dates, or at least a duration and the conditions that start the clock?
- Signatures and attachments: Are the drawings, finish schedule, estimate, and exclusions part of the same agreement, with a date or revision number?
Ontario says renovation contracts over $50 must be in writing and should state the contractor's contact information, detailed work and materials, warranties, total cost and payment terms, schedule, deposit, cleanup responsibility, and subcontracting arrangements. The government's guide for renovation and roofing businesses describes the supplier side.
Read the scope one finished surface at a time
To test a scope, mentally walk the finished room. Touch every visible surface and ask where it appears in the quote, then work backward into the hidden layers. A bathroom is not just tile and fixtures. It is demolition, disposal, framing, plumbing, electrical, ventilation, substrate, waterproofing, finishes, inspections, protection, and cleanup.
| Area | Useful detail | Vague version to question |
|---|---|---|
| Demolition | What is removed, what remains, disposal, protection, and any hazardous-material assumption | Demo as required |
| Materials | Manufacturer or performance level, product line, size, finish, quantity, and who purchases it | Supply quality materials |
| Installation | Substrate preparation, layout, fastening or setting method, transitions, and finish standard | Install tile |
| Trades | Which licensed or qualified trade does what, including notifications and inspections | Electrical and plumbing included |
| Completion | Cleanup, disposal, commissioning, inspection documents, manuals, warranty, and deficiency process | Final cleanup |
A useful scope does not specify every screw. It does define the outcome and the choices that affect performance or price. Install owner-selected tile is weak. Install porcelain tile up to a stated material allowance over the specified uncoupling membrane, including standard grid layout, grout, edge profiles, and transitions is comparable. The second version gives bidders the same installation to price.
If you are comparing kitchen numbers, the line-by-line categories in our GTA kitchen renovation cost guide make a useful cross-check. For bathrooms, use the same method with the GTA bathroom renovation cost guide. Use the categories to check your quotes for missing work.
Check what each allowance buys
An allowance can help when a product has not yet been selected. A realistic allowance lets design continue before every faucet and handle is chosen. Check whether the allowance covers products you would actually choose; otherwise your working budget is too low.
- Ask whether the allowance covers material only or material plus delivery, handling, installation, waste, and tax.
- Ask for a sample product that fits the allowance. If none suits your needs, revise the allowance before signing.
- Ask how savings and overruns are reconciled. Both directions should use the same arithmetic.
- Ask whether contractor markup applies to an allowance overrun and whether it was already included in the base amount.
- Set selection deadlines. A tile choice made after the installer is booked can affect time even if it fits the allowance perfectly.
Exclusions deserve the same attention as inclusions
A clear exclusion tells you what remains outside the price. Concealed damage, asbestos remediation, utility upgrades, engineering, permit fees, appliance installation, adjacent painting, and out-of-area patching may all be reasonable exclusions. Ask about any necessary work missing from both the price and the exclusions.
Circle if required, by owner, not included, TBD, and as needed. Ask what turns each phrase into a price. If the answer is known now, price it now. If it is genuinely unknowable, define the investigation, rate, allowance, or change-order process.
Assign permits and licensed work
Ontario's consumer guide says the homeowner remains responsible for building permits and legal requirements. A contractor can act on your behalf, but the contract should say who prepares drawings, pays fees, submits, answers comments, books inspections, and provides final records. Obtain required permits before starting the work they cover.
Electrical work deserves its own line. The Electrical Safety Authority says that almost all electrical work must be reported through an ESA notification and that a person hired to perform electrical work in an Ontario home must be a Licensed Electrical Contractor. The quote should identify the electrical contractor's ECRA/ESA licence number and notification fee where applicable. Fuel work has its own regime: TSSA's registry lets you verify an authorized fuels contractor.
Match payments to progress you can see
Tie payments to agreed progress you can verify. Second payment on September 15 tells you nothing if cabinets have not arrived. Second payment after rough framing is complete and the applicable inspection has passed ties money to an observable result.
- Keep the deposit modest. Ontario recommends no more than 10% as consumer guidance, although that recommendation is not the same thing as a universal statutory deposit cap.
- Avoid front-loading. Payments should not leave the contractor paid far ahead of completed work and delivered materials.
- Define what evidence unlocks a milestone: delivery, completed installation, inspection, or signed review.
- Keep the statutory Construction Act holdback separate from a contractual deficiency amount. The Construction Act generally requires a 10% holdback where the Act applies, with technical timing rules. Get legal advice for the release date on a substantial project, especially after Ontario's 2026 amendments.
- Require invoices and receipts that identify the contracting entity. Verify a GST/HST number with the Canada Revenue Agency's registry if something does not line up.
Compare three quotes on the same basis
Ontario recommends at least three written estimates. Compare them only after normalizing scope, material tier, allowances, exclusions, permits, design, trades, protection, disposal, tax, schedule, warranty, and payments. Put each contractor in a column. Leave blanks as blanks. Ask about a blank rather than assuming the item is included.
Ask every contractor the same short questions in writing, then judge the answers as part of the quote. How clearly a contractor answers now is useful information about working together later.
- Which three items are most likely to change this price?
- Which products are allowances, and what specific products fit each allowance today?
- What work must be completed by the owner or another vendor?
- Which permits, notifications, inspections, and professional drawings are included?
- What is the change-order markup, and how are schedule effects shown?
Reasons to pause before signing
- A large deposit demanded immediately to hold a price, especially with pressure to sign at home.
- A cash discount tied to no invoice, no HST, or no written contract.
- A total with no meaningful scope, or a scope full of standard, quality, and as required without definitions.
- No physical business address, a payment recipient that does not match the contractor, or resistance to providing licence information for regulated trades.
- Full payment due before final inspection, deficiency review, or delivery of closeout records.
Before signing, search both the business and operator on Ontario's Consumer Beware List, verify regulated trades, call references for similar work, and read the contract without the salesperson waiting beside you. If you sign a qualifying renovation or repair agreement worth $50 or more in your home, Ontario's current guidance says a 10-calendar-day cooling-off period generally applies. Work requested during that period can create an obligation to pay reasonable compensation for work and non-returnable materials, so clarify the consequences before requesting early work.
A quote cannot predict every concealed condition. It should distinguish known work from assumptions and explain how changes will be agreed. Pair this checklist with our Ontario contractor-verification guide, then choose the proposal you understand, not merely the number you hope is true.
