Average renovation costs in Canada — 2026
Canadian renovation costs are typically quoted per square foot of affected area. For whole-home renovations — defined as significant work across multiple rooms, including kitchen, bathrooms, and potentially structural changes — the range sits between $125 and $275 per square foot as of 2026. The wide range reflects differences in finish level, regional labour rates, and the age of the home.
For context, Ontario homeowners undertaking a whole-home renovation on a home between 1,250–1,600 sq ft spent an average of $52,275, with the range from $19,500 to $88,400 capturing the spread from cosmetic refreshes to full gut renovations.
Project-specific cost ranges (Canada, 2026)
| Project | Low | Average | High |
|---|---|---|---|
| Kitchen renovation | $15,000 | $32,000 | $65,000+ |
| Bathroom renovation | $8,000 | $14,500 | $28,000+ |
| Basement finishing | $20,000 | $33,000 | $55,000+ |
| Roofing (shingle replacement) | $5,000 | $9,500 | $18,000 |
| Window replacement (10 windows) | $8,000 | $14,000 | $22,000 |
| Deck construction (standard) | $7,000 | $13,000 | $25,000+ |
| Furnace replacement | $3,500 | $5,500 | $9,000 |
| Electrical panel upgrade (200A) | $2,500 | $4,000 | $7,500 |
Toronto and Vancouver consistently run 20–35% above the averages shown. Rural and smaller-city markets tend to run 10–20% below. Ottawa, Calgary, and Edmonton generally track close to the national average.
The renovation timeline, phase by phase
Realistic renovation timelines are longer than most homeowners anticipate at project outset. The phases where time is consistently underestimated are design and drawings, permit processing, and material lead times — none of which are within a contractor's control once a project is underway.
Planning and scope definition (1–3 weeks)
Before any money changes hands, a clear written scope is necessary. This means room-by-room descriptions of what's changing, decision points on finish level (mid-range vs. custom), and explicit decisions on what's out of scope. Projects that start without a defined scope are the ones that expand by 50% mid-construction.
Design, drawings, and engineer review (3–8 weeks)
For projects requiring structural changes or additions, stamped engineer drawings are required for permit applications. Finding an engineer who is available and familiar with residential work in your municipality takes time. For kitchen and bathroom renovations that don't touch structural elements, a designer's drawings or detailed contractor sketches may suffice for permit purposes.
Contractor selection and quoting (2–5 weeks)
Getting three written quotes from licensed contractors — and actually comparing them properly — takes time. General contractors are typically booked 4–12 weeks out for the start of major work in most Canadian markets. Don't compress contractor selection to accept the first available start date.
Permit application and approval (2–8 weeks)
As covered in the building permits guide, permit timelines vary significantly by municipality. Plan for 4–6 weeks as a baseline for most major Canadian cities. This phase runs in parallel with contractor selection once drawings are complete.
Material ordering and lead times (2–8 weeks)
Custom cabinetry is typically 6–10 weeks from order to delivery. Windows are often 4–8 weeks. Tile from certain suppliers runs 3–6 weeks. Appliances can be in stock or 6+ weeks out depending on model. Material lead times are a frequent cause of mid-project delays and should be mapped out before construction begins.
Construction (6 weeks to 8+ months)
A bathroom renovation runs 2–4 weeks of active construction. A kitchen runs 4–8 weeks. A basement finish with electrical and plumbing rough-in typically runs 8–12 weeks. A whole-home renovation on a 1,500 sq ft home is realistically 5–8 months of construction. These timelines assume good coordination between trades — delays in one trade (plumber hasn't roughed in before the electrician needs to work) cascade quickly.
Inspections and closeout (1–3 weeks)
Final inspections, occupancy certificates (for additions with a secondary suite), and contractor deficiency walkthroughs add time at the end. Don't assume a project is done until the final inspection is passed and a written deficiency list from your walkthrough has been addressed.
Contingency budgeting
The standard contingency recommendation for Canadian renovations is 10–15% of the total project cost for homes built after 1990, and 15–25% for homes built before 1980. Pre-1980 homes commonly contain surprises behind walls: galvanized plumbing past its service life, knob-and-tube or aluminum wiring that triggers code upgrades, asbestos in insulation or drywall compound, and undersized structural members that don't meet current load requirements.
Contingency is not a slush fund for scope additions — it's specifically for unexpected conditions discovered mid-project. Keep it separate from the base budget and resist the temptation to spend it on finish upgrades when the project is going smoothly.
What consistently drives overruns
- Scope changes mid-construction. Every change order issued during active construction costs more than the same change made before work started. Structural changes after framing inspection are particularly expensive.
- Discovering existing non-code-compliant work. Opening a wall in a pre-1990 home often reveals plumbing or wiring that must be brought to current code before new work can proceed. This is a permit condition in most municipalities.
- Material cost increases. Lumber and engineered wood products have had significant price volatility since 2020. Quotes locked in January may not hold in June for a project that didn't start until April.
- Inadequate contractor coordination. Projects managed without a general contractor (owner-managed with direct-hired subtrades) run longer on average because the homeowner is managing scheduling coordination between trades without experience doing so.
How to compare contractor quotes
Three quotes is the standard minimum. When comparing them, ensure each quote covers the same scope — an apparent 20% price difference often disappears when you notice one quote excludes permit fees, disposal, or a critical trade. Ask each contractor to break out materials separately from labour. Verify that all contractors are providing quotes for the same finish level (standard vs. premium fixtures, for example). Confirm that HST/GST is included or clearly excluded in each quote.
References matter more than price. A contractor who comes in 10% higher with documented references from comparable projects in your neighbourhood is generally a lower risk than the cheapest quote from an unknown operator.
