Read every renovation quote from the scope outward, never from the total upward. A grand total is just the last cell in a spreadsheet. If one kitchen quote includes disposal, electrical notifications, finished drywall, hardware, floor protection, and HST while another leaves those items for later, the cheaper number has not won. It has simply arrived underdressed. The Ontario renovation HST guide explains how to verify that tax line.
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, run five blunt checks. If a quote fails one, send it back for revision. Homeowners should not need detective training to buy a bathroom.
- 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. We like this part boring. Boring paperwork is lovely paperwork.
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.
Swipe to compare
| 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. One is a scope. The other is a shrug with punctuation.
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. Do not borrow the totals. Borrow the list of things that should not vanish between pages.
Allowances are decisions on layaway
We like allowances when they solve a real timing problem. A realistic allowance lets design continue before every faucet and handle is chosen. A tiny allowance exists mainly to make the quote look lean today and the invoice look surprised later. That shortcut deserves daylight.
- 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 nobody can name one you would actually buy, the allowance is decorative fiction.
- 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
We respect a clear exclusion. It shows the edge of what a contractor knows and has priced. Concealed damage, asbestos remediation, utility upgrades, engineering, permit fees, appliance installation, adjacent painting, and out-of-area patching may all be reasonable exclusions. What makes us suspicious is a necessary, foreseeable item 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. Fog is weather, not a scope-writing technique.
Permits, licensed work, and the person holding the clipboard
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. Our rule is firm: permit-required work does not begin because somebody says the permit is basically in process.
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
We prefer payments tied to completed, visible milestones, not dates floating loose on a calendar. 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. Money should not outrun the work.
- 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.
Normalize three quotes before choosing one
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. Never donate an inclusion to a quote that did not earn it.
Ask every contractor the same short questions in writing, then judge the answers as part of the quote. Clear questions should produce clear answers. If asking whether disposal is included launches a six-message philosophical debate, imagine discussing a wet subfloor on demolition day.
- 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?
Red flags that are actually red
- 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 do not treat the cooling-off period as a free demolition coupon.
We do not expect a quote to predict the future perfectly. Houses are rude enough to hide things. We do expect it to identify what is known, label what is not, price what can be priced, and give both sides a calm procedure for the rest. Pair this checklist with our guide to hiring a carpenter in the GTA, then choose the proposal you understand, not merely the number you hope is true.
