How much does a home renovation cost in Canada? Cost drivers and illustrative ranges
What drives renovation prices in Canada, illustrative per-square-foot ranges for common projects, how those ranges are built and how to turn them into a budget.
There is no single price for a renovation in Canada. What you pay depends on what is in scope, how many square feet it covers, the finish level, how much structural, plumbing, electrical and HVAC work is involved, local labour rates, permits, and how many unknowns the house is hiding. A cosmetic refresh can cost a few tens of dollars per square foot; a gut kitchen or bathroom can cost many hundreds per square foot because cabinets, fixtures and several trades are concentrated into a small room. The fastest way to a realistic number is to define the scope, apply a per-square-foot range to it, add one-time costs, a contingency and sales tax, and then replace your assumptions with written quotes.
This overview links to every guide in the costs section: kitchen renovation cost, bathroom renovation cost, basement finishing cost, home addition cost, GST/HST on renovations and renovation tax credits in 2026.
Illustrative cost ranges by project type
The table shows the presets used in our renovation cost estimator. They are illustrative, before tax, in Canadian dollars per square foot of renovated floor area.
| Project type | Illustrative range per sq ft | Example size | Illustrative total before tax and one-time costs |
|---|---|---|---|
| Basement finishing, no bathroom | $45–$85 | 800 sq ft | $36,000–$68,000 |
| Basement finishing with a bathroom | $70–$125 | 800 sq ft | $56,000–$100,000 |
| Basement secondary suite | $150–$275 | 700 sq ft | $105,000–$192,500 |
| Kitchen, mid-range | $250–$500 | 150 sq ft | $37,500–$75,000 |
| Kitchen, custom or high-end | $500–$1,000 | 150 sq ft | $75,000–$150,000 |
| Bathroom, full gut, mid-range | $450–$850 | 50 sq ft | $22,500–$42,500 |
| One-storey addition | $350–$650 | 400 sq ft | $140,000–$260,000 |
| Whole-home cosmetic refresh | $40–$100 | 1,800 sq ft | $72,000–$180,000 |
| Whole-home gut renovation | $250–$450 | 1,800 sq ft | $450,000–$810,000 |
How we built these ranges
Each range is an editorial illustration. We started from the components a contractor would price for that project (demolition and disposal, framing, insulation and drywall, flooring, cabinets and fixtures where relevant, plumbing, electrical and HVAC work, finishing, and the contractor's overhead and profit), assumed a mid-sized house in an urban market, and rounded the sum to a range wide enough to cover basic to better finishes. They are not taken from surveys, published price lists or any company's quotes, and they are not averages. No official body publishes a national renovation price index for homeowners, so treat any single "average cost" you see online with caution and ask how it was built.
The main cost drivers
Scope and size
Area matters, but the number of wet rooms and trades matters more. A kitchen of 150 sq ft has cabinets, counters, appliances, plumbing, a dedicated electrical circuit for the range, ventilation and lighting; a bedroom of the same size has paint and flooring. That is why kitchens and bathrooms dominate per-square-foot tables.
Finish level
Moving from stock to semi-custom to custom cabinetry, from laminate to quartz or stone counters, or from vinyl plank to hardwood or large-format tile can double the materials line. Finish level is the driver you control most directly, and it is where allowances in a quote often hide.
Structural, mechanical and code work
Removing a load-bearing wall needs a beam, posts, sometimes engineering and footings. Moving a toilet or a kitchen sink across the room means new drain lines, possibly through the floor structure or slab. Older electrical panels may lack capacity for new circuits. Bringing an older house up to current code where the work touches it (smoke alarms, egress windows, fire separation for suites) adds cost that cosmetic estimates ignore.
Location and labour market
Labour rates and the availability of trades vary between large metro areas, smaller cities and rural or northern communities, where travel time and shipping materials add up. Busy seasons also matter: exterior work and additions compete for crews in spring and summer.
Permits, drawings and inspections
Municipal permit fees, drawings, engineering letters and the time lost waiting for inspections all belong in the budget. See building permits and inspections.
The house itself
Age, condition and access drive surprises: asbestos-containing materials in pre-1990 houses, knob-and-tube wiring, galvanized plumbing, rot, a basement with moisture history, a narrow lot where materials must be carried in by hand. Each one belongs in your contingency.
From range to budget: a short worked example
Illustrative: finishing an 800 sq ft basement in Ontario without a bathroom.
- Area × illustrative range: 800 × $45 = $36,000 (low); 800 × $85 = $68,000 (high).
- One-time costs (drawings, permit, bin): $3,000. Range: $39,000–$71,000.
- Contingency at 15% of the high figure: $71,000 × 15% = $10,650. Budget ceiling before tax: $81,650.
- HST at 13%: $81,650 × 13% = $10,614.50. Ceiling with tax: $92,264.50.
The steps match the estimating method, and the calculators handle the contingency and the sales tax.
Costs people forget
- Living elsewhere during a kitchen or whole-home job: rent, storage, eating out.
- Appliances and fixtures you buy yourself, which carry tax at the store and may not be covered by the contractor's warranty.
- Design fees charged whether or not you go ahead.
- Higher property tax after a major addition or suite, once the assessment is updated.
- Insurance: tell your home insurer about major renovations; some policies have conditions for vacant or under-construction homes.
- Financing costs if you borrow against the home.
Related projects covered elsewhere
Roof replacement, heating systems and heat pumps, solar panels, water leak repairs and window replacement have their own price logic and programs. We only touch on them here. If your renovation includes them, get separate quotes from specialists and check provincial energy-efficiency programs and your municipality's rules.
Mistakes to avoid
- Using a national "average" without knowing what it includes.
- Comparing quotes that price different scopes.
- Forgetting tax: on a $60,000 Ontario contract, HST alone is $7,800.
- Spending the contingency on upgrades before the walls are open.
- Skipping permits to save time, then paying for it at resale or with your insurer.
FAQ
What is a realistic price per square foot for a renovation?
It depends on the room. Our illustrative presets run from around $40–$100 per sq ft for a cosmetic refresh to several hundred dollars per sq ft for kitchens and bathrooms. Replace them with quotes from your area.
Why is my quote much higher than online averages?
Online averages rarely say what they include. Structural work, plumbing moves, older houses, permits and higher-end finishes can push a quote far above a generic figure. Ask the contractor for a line-item breakdown.
Should I renovate in phases?
Phasing can spread cost, but repeated mobilisation, permits and demolition can make the total higher. Plan the rough-in work (plumbing, electrical, ducting) for later phases now.
Do renovations add equivalent value to the home?
Not necessarily. Resale value depends on the local market. Treat a renovation primarily as a cost for your use of the home, and ask a local real estate professional if resale value matters.
