// note Estimate only — Canadian basement renovation costs vary widely by city (Toronto/Vancouver run 20–30% higher than national average). Sales tax assumed payable on labour + materials. Egress windows are required by code for legal bedrooms. Exterior waterproofing only adds cost if you have a water-ingress problem.
