Toronto cost guide
Whole-home renovation cost in Toronto (2026).
A whole-home renovation in Toronto in 2026 generally runs about $60 to $100 per square foot for a cosmetic refresh, $100 to $175 for a mid-range renovation, and $175 to $350 per square foot for a full gut and rebuild. Across Toronto and the 905, that puts a comprehensive gut-and-rebuild at roughly $300,000 to $700,000 before HST, an addition or a lowered basement.

Where the money actually goes
Age and condition of the house
The biggest unknown
Knob-and-tube wiring, galvanized or lead supply lines, clay drains, balloon framing and no insulation are common in pre-war Toronto stock and each carries real cost.
Structure and engineering
Drives permits and schedule
Removing load-bearing walls, adding beams, underpinning or lowering a basement all need drawings, permits and inspection windows.
Mechanical, electrical and plumbing
Often 20–30% of a gut job
A new panel and service upgrade, full rewire, repiping and HVAC redesign are frequently underpriced in optimistic quotes.
Kitchen and bathrooms
Selection-driven
These rooms usually carry the largest allowances, so they explain most of the gap between two quotes on the same house.
Schedule, supervision and contingency
Rarely a visible line
Six to twelve months of site supervision, temporary housing and a 10–15% contingency belong in your budget even if they are not in the quote.
The anatomy of a whole-home quote
On a project this size the contract language matters as much as the total. Work down these lines and ask the question beside each one before you sign.
| Quote line | What to ask |
|---|---|
| Scope definition | Which drawings and specification set is this price based on, and what revision date? |
| Contract type | Is this fixed price, cost-plus with a fee, or an estimate that can move? Where does it say so? |
| Allowances schedule | What dollar figure is assumed for cabinets, tile, fixtures, flooring and appliances, and how are overages priced? |
| Permits, engineering, surveys | Who applies, who pays, and what happens to the schedule if the city takes longer than assumed? |
| Existing conditions | What is assumed reusable — wiring, plumbing stacks, framing, foundation — and who carries the cost if it isn't? |
| Change order process | How is a change priced and approved, and what markup applies to extras? |
| Payment schedule and holdback | Are payments tied to completed milestones, and is the Ontario construction holdback handled properly? |
| Exclusions | What is explicitly excluded, and which of those items will you still have to pay someone for? |
Frequently asked questions
How much does a whole-home renovation cost in Toronto?
In 2026, published GTA guides put a comprehensive gut-and-rebuild at roughly $150 to $350 per square foot, or about $300,000 to $700,000 for a typical home. Cosmetic whole-house refreshes can run closer to $60 to $100 per square foot.
Why do whole-home quotes vary so much between Toronto contractors?
Large quotes differ mainly in what they assume rather than in their labour rates: allowance levels, how much existing wiring and plumbing is reused, whether permits and engineering are included, and whether the price is fixed or an estimate. A 30 to 50 percent spread on the same house is common.
How much contingency should I budget?
For a gut renovation of an older Toronto home, 10 to 15 percent above the contract price is a reasonable contingency, because hidden conditions behind plaster and below the floor are only discovered after demolition.
Should I get a second opinion before signing a large renovation contract?
On a project of this size a review is cheap insurance. Arden reviews your quote for $49 and shows you the missing scope, thin allowances and contract terms to raise before you sign.
