Ways to price and run a renovation, compared

ArrangementHow it worksBest fit whenWatch out for
Fixed price (stipulated sum)One price for a defined scope; changes are priced through written change ordersPlans and finishes are chosen before signing and the house has few unknownsThin scope descriptions, low allowances and expensive change orders; hidden conditions may be excluded
Fixed price with allowancesFixed price for labour and most materials, plus dollar allowances for items you pick laterYou need to start before every finish is selectedAllowances 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 feeOlder houses with many unknowns, or high-end work where choices evolveNo ceiling unless the contract sets one; you need invoices and regular cost reports
Time and materialsHourly or daily labour rate plus materials, billed as work proceedsSmall repairs and jobs where the scope cannot be definedBudgets drift; ask for a written estimate and, in Ontario, note the CPA's limit on charging more than 10% above an estimate

Frequently asked questions

How much does a home renovation cost in Canada?

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.

Are your cost ranges real market prices?

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.

Do I pay GST/HST on a renovation?

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.

How much contingency should I add?

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.

How big a deposit should I pay a contractor?

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.

Do I need a building permit to renovate?

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.

Is there a federal tax credit for renovations in 2026?

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.

Do you rank or recommend contractors?

No. We do not publish rankings, ratings, reviews or testimonials, and we are not paid by contractors to appear on the site. We explain how to compare quotes and what to check on official registers so you can choose the best fit for your project.
