How to Compare Renovation Quotes in Ontario
Learn how to compare renovation quotes in Ontario: same scope, fixed price vs estimate, allowances, exclusions, HST, and the 10% rule. Practical guide.
Comparing renovation quotes is not a matter of lining up the totals and picking the lowest. A quote is only meaningful when every bidder priced the same scope, the same materials and the same responsibilities. Most of the work of comparing happens before the first quote arrives: writing a clear scope, sending the same package to every contractor, and asking each one to break the price down the same way. Once the quotes are in, the comparison is about what is included, what is excluded, and what kind of price you are actually being given.
Start with one written scope for every bidder
If three contractors walk through the same kitchen and each writes their own scope, you will get three quotes for three different jobs. One includes new drywall, one patches, one allows for new wiring, one does not. The totals will differ for reasons that have nothing to do with value.
Write a scope document before you call anyone. It should list the rooms, the work, the fixtures and finishes you want, and what is staying. Say who supplies what: tiles, cabinets, the vanity, the light fixtures. State what is not included. Send the same document to every bidder and ask them to price it line by line.
This is also the moment to settle the big decisions. Changing the layout after quotes are in means every quote has to be redone. The step-by-step decisions that come before hiring are set out in how to plan a home renovation in Ontario.
Fixed price, estimate, or cost-plus
Quotes come in three broad forms, and they are not interchangeable.
| Type | What it means | What to watch |
|---|---|---|
| Fixed price (or stipulated price) | The contractor commits to a price for the defined scope | Only as good as the scope; changes go through change orders |
| Estimate | A prediction of what the work will cost | Under the Consumer Protection Act, a contractor may not charge more than 10% above a written estimate unless you agree to new or different work or a new price |
| Cost-plus | You pay the contractor’s costs plus a fee | The fee and the definition of costs need to be in writing; the final price is open-ended |
A fixed price is not automatically better. It is only fixed for the scope written down. If the scope is vague, the fixed price will be padded to cover the unknowns, or it will be abandoned once the work starts. An estimate gives less certainty but can be appropriate where the work is genuinely hard to define, such as opening a wall in an older house. Cost-plus shifts the risk of surprises to you and is best used with a very clear definition of costs and a cap you can live with.
Ask each bidder which form they are using, and make sure the contract says the same thing. The Consumer Protection Act, 2002 requires a home renovation contract to be in writing, and the province advises that it include a detailed description of the work and materials, the total price and payment terms, start and completion dates, warranties, and which trades are subcontracted. A quote is not a contract; the contract is what protects you. The items to check are listed in the renovation contract checklist for Ontario homeowners.
Read the breakdown, not just the total
A contractor quote breakdown should let you see where the money goes. Ask for the price split into labour and materials by trade or by room, and for the major items listed separately: cabinets, countertops, flooring, plumbing fixtures, electrical, drywall, painting, cleanup and disposal.
A one-line quote for a whole kitchen tells you nothing. You cannot tell whether the electrical allowance is realistic, whether disposal is included, or whether the tile is an allowance or a fixed selection. When quotes are broken down the same way, you can compare line to line and see which bidder is cheaper on framing and more expensive on finishes, and why.
Ask each bidder to state:
- What is included and what is excluded.
- Who obtains permits and who pays for them.
- Who arranges inspections and who is on site to meet the inspector.
- Who supplies and who installs fixtures and finishes.
- Who protects floors and furniture, and who removes debris.
- Whether the price includes HST.
Allowances and exclusions
An allowance is a placeholder sum for something not yet chosen, such as tile, lighting or a vanity. It is not a price. If the allowance is low and your actual selection costs more, you pay the difference. Two quotes can look similar and behave very differently if one carries realistic allowances and the other carries low ones to keep the total down.
Ask for every allowance to be listed with its amount and what it covers, and ask what happens if you go over. A quote with generous allowances may be more honest than one with low allowances and a lower total.
Exclusions matter just as much. Common exclusions include permits, engineering, asbestos testing or removal, electrical work beyond a set number of outlets, repairing what is found behind a wall, and HST. An exclusion is not necessarily unfair, but it has to be visible before you compare totals. Add the likely cost of each exclusion to the quote in your own notes so the comparison is like for like.
HST and the number you actually pay
Ontario’s HST is 13% (5% federal and 8% provincial) and applies to renovation labour and materials. A quote should say whether HST is included. A quote that excludes HST is not comparable with one that includes it, and the difference is large enough to change the ranking. Ask every bidder to state it plainly in writing.
The province’s advice on three estimates
The province recommends getting written estimates from at least three contractors. Three quotes do more than find a price: they show you the range, reveal what different contractors think the job involves, and give you a basis for asking questions. If one quote is far below the others, that is a question, not a bargain.
Why renovation quotes are so different
Homeowners often ask why renovation quotes vary so widely for what looks like the same job. The usual reasons:
- Different scopes, because the bidders interpreted a vague brief differently.
- Different allowances, as above.
- Different assumptions about what is behind the walls, especially in older homes.
- Different crews: one contractor uses employees, another subcontracts every trade.
- Different overheads and insurance costs, which are legitimate differences.
- Different permit and inspection responsibilities.
- Different finish levels, even when the words in the scope are the same.
A quote that is far lower than the rest deserves scrutiny. Ask what is excluded, what allowances are set, whether permits and HST are in, and what happens if the work turns out to be more involved. A low quote that grows through change orders is not cheaper. The warning signs to weigh alongside price are covered in how to choose a renovation contractor in Ontario.
Questions to put to every bidder
Before comparing totals, ask each bidder the same questions and write the answers down:
- Is this a fixed price, an estimate or cost-plus?
- What is excluded, and what would each exclusion likely add?
- What allowances are included, and at what amounts?
- Is HST included?
- Who pulls the permits, and are permit fees in the price?
- Who is responsible for utility locates before digging?
- Which trades are subcontracted, and who pays them?
- What is the payment schedule and deposit?
- What warranty do you provide, and for how long?
- What is the start date and completion date?
Some of these are legal matters. Paid electrical work must be done by a Licensed Electrical Contractor with an ESA permit; gas work by a TSSA-registered contractor; plumbing changes need a plumbing permit and a licensed plumber; structural changes need a design by a qualified designer or engineer and a building permit. A quote that quietly leaves these out is not a complete price. How the law applies to a particular contract is a question for a lawyer.
What goes wrong when comparing quotes
- Comparing totals from different scopes. The most common mistake. Fix the scope first.
- Ignoring allowances. A low allowance is a future extra, not a saving.
- Missing exclusions. Permits, HST, asbestos testing and hidden repairs are frequent omissions.
- Choosing on price alone. The lowest quote is not the lowest cost if it grows through change orders or is backed by weak insurance and no written contract.
- Skipping the contract. A quote is a sales document; the written contract is what you can rely on.
- Paying too much up front. The province recommends a deposit of no more than 10% of the contract price.
- Forgetting the holdback. Under the Construction Act, every payer, homeowners included, must hold back 10% of each payment. A subcontractor can lien a home even when the general contractor has been paid. How this applies to one contract is a question for a lawyer.
- No change orders. Any change to scope, price or schedule should be written and signed by both sides before the extra work is done.
- Not checking the permit stage. Covering work before it is inspected can mean opening it up again.
Turning the chosen quote into a contract
Once you have chosen, the quote becomes the basis of the written contract, not a substitute for it. The contract should repeat the scope, the price and what it includes, the allowances, the exclusions, the payment schedule, the start and completion dates, the warranty and the cleanup. Attach the quote and the scope as schedules so there is no argument later about what was priced.
A contract signed in the home can be cancelled for any reason within 10 days of receiving the written copy. That cooling-off period is a protection, not a reason to sign quickly. Read the contract before you sign, and take advice if anything in it is unclear.
Common questions
What is the difference between a renovation estimate and a quote?
An estimate is a prediction of what the work will cost; a quote, often called a fixed or stipulated price, is a commitment to a price for a defined scope. Under Ontario's Consumer Protection Act, a contractor may not charge more than 10% above a written estimate unless you agree to new or different work or a new price. Ask each bidder which one you are getting.
Why are renovation quotes so different for the same job?
Usually because the bidders priced different scopes, used different allowances, made different assumptions about what is behind the walls, or included different permits, trades and finish levels. Sending one written scope to every bidder and asking for the same breakdown makes the quotes comparable.
Should I choose the lowest quote?
Not on price alone. A quote that is far below the others often excludes permits, HST or key trades, or carries low allowances that become extras later. Compare what is included and excluded, the allowances, the payment schedule and the warranty before deciding.
Do contractor quotes include HST in Ontario?
Not always. Ontario's HST is 13% and applies to renovation labour and materials, so a quote should state whether HST is included. A quote that excludes HST is not comparable with one that includes it.
How many quotes should I get for a renovation?
The province recommends written estimates from at least three contractors. Three quotes show you the range, reveal what different contractors think the job involves, and give you a basis for asking questions before you sign a contract.
