Illustrative kitchen remodel ranges for Canadian homes, the cost of cabinets, counters, layout changes and trades, a worked budget and how to read kitchen quotes.
Pitfalls, disputes and official sources
The most common ways Canadian renovations go wrong, which official body or statute deals with each, and a directory of federal, provincial and municipal sources to verify rules.
Turn the floor area of your project into an illustrative low-to-high price range by project type, plus one-time costs such as design, permits and disposal.
Add GST/HST, or GST plus QST or PST, to a renovation contract price to see the tax and the total you will actually pay.
Add a contingency percentage and fixed allowances to your base estimate to get a total renovation budget you can plan around.
Work out how much to keep back from a renovation progress invoice under a provincial lien act, and how much to pay now after deposits.
Check that every contractor quote covers the same scope and the protections you need before you compare prices or pay a deposit.
| Arrangement | How it works | Best fit when | Watch out for |
|---|---|---|---|
| Fixed price (stipulated sum) | One price for a defined scope; changes are priced through written change orders | Plans and finishes are chosen before signing and the house has few unknowns | Thin scope descriptions, low allowances and expensive change orders; hidden conditions may be excluded |
| Fixed price with allowances | Fixed price for labour and most materials, plus dollar allowances for items you pick later | You need to start before every finish is selected | Allowances set unrealistically low to make the quote look cheaper; check whether they include installation and tax |
| Cost-plus (percentage or fixed fee) | You pay actual costs of labour, materials and subtrades plus a markup or fixed fee | Older houses with many unknowns, or high-end work where choices evolve | No ceiling unless the contract sets one; you need invoices and regular cost reports |
| Time and materials | Hourly or daily labour rate plus materials, billed as work proceeds | Small repairs and jobs where the scope cannot be defined | Budgets drift; ask for a written estimate and, in Ontario, note the CPA's limit on charging more than 10% above an estimate |
It depends on the project, the floor area, the finish level, the age of the house and your local labour market. As an illustration only, finishing an 800 sq ft basement without a bathroom might fall somewhere around $39,000–$71,000 before tax with our preset assumptions, while a mid-range kitchen or a full bathroom costs far more per square foot. Use the estimator and then replace the presets with written quotes.
No. They are illustrative ranges we build from typical components and round, explained on each page. They are not surveys, averages or quotes, and they can be wrong for your city, your house or this year's material prices. Their purpose is to help you sanity-check a budget and ask better questions.
Generally yes. Renovation services and materials supplied by a GST/HST-registered contractor are taxable, at 13% HST in Ontario, 14% in Nova Scotia, 15% in the other Atlantic provinces and 5% GST elsewhere, plus QST in Quebec and PST in Saskatchewan. See GST/HST on renovations.
There is no official figure. A common planning rule is around 10% for straightforward cosmetic work and 15–20% or more for older houses, structural changes or projects without final plans. The contingency calculator does the arithmetic.
Keep it modest and tied to real costs such as custom-ordered materials, and pay the rest in stages as work is completed and inspected. In Quebec, an RBQ-licensed contractor's licence security can help in limited cases if a deposit is lost. See deposits and holdbacks.
Often. Structural changes, additions, new plumbing, basement finishing and secondary suites generally need a permit from your municipality, while painting or replacing cabinets in the same layout usually does not. Your city's building department decides; see permits and inspections.
There is no general one. The Multigenerational Home Renovation Tax Credit applies when you create a secondary unit for a senior or an adult with a disability to live with a relative, and the Home Accessibility Tax Credit applies to accessibility work for qualifying individuals. The Canada Greener Homes Grant and Loan are closed to new applicants. See renovation tax credits in 2026.
