Introduction

Not all renovations are created equal when it comes to adding value to your home. Some projects can return 90%+ of their cost when you sell, while others barely recoup 50%. Understanding which renovations offer the best return on investment (ROI) is crucial whether you're preparing to sell or simply want to make smart improvements.

In this comprehensive guide, we'll break down the renovations that add the most value to Canadian homes in 2025, backed by real data and expert insights.
