What nine of the most common home projects actually cost in Ontario this year — planning ranges drawn from NorthPeak's free Canadian cost calculators, calibrated to published 2026 contractor pricing.
Ontario renovation costs in 2026 remain sharply tiered by scope: the gap between a cosmetic refresh and a full gut is typically 2–4×, and the single biggest cost driver across nearly every project is labour and site preparation — the work hidden under the finished surface.
Key findings: a mid-range bathroom runs $10,000–$21,000+ while a primary ensuite reaches $35,000+; a full basement finish costs $50–$100 per square foot province-wide (up to $130 in Toronto); and a standard furnace-plus-AC replacement for an 1,800 sq ft Ontario home lands at $8,000–$13,900.
On the financing side, a $500,000 Ontario home with 20% down at a 5.00% rate costs roughly $2,326/month in principal and interest alone — before taxes, insurance, or utilities. Every figure in this report links back to a free NorthPeak calculator where readers can build their own estimate.
Moving plumbing and custom showers are the two great budget multipliers.

This report compiles the planning ranges published on NorthPeak Estimates' free Canadian cost calculators, each calibrated to published 2026 contractor pricing and checked in October 2026. Figures are budgeting ranges — not contractor quotes — and exclude HST/GST unless noted. Regional labour, site access, finish level, and hidden conditions (moisture, structural issues, outdated wiring) can move real quotes outside these bands.
Calibration sources cited across the calculators include HomeStars (2026 Canadian cost guides), Angi (2026 national data), HomeAdvisor, Home Depot Canada, the Canadian Home Builders' Association, and Networx. The mortgage example uses the standard Canadian semi-annual compounding formula. Full per-figure sourcing is documented in the report's data file.
