Methodology

What these numbers are — and aren't

Every figure is a declared construction value from a Toronto building permit, classified by GROUND's cost taxonomy (minimum 8 comparables per published category) over the trailing 24 months. Declared values can understate actual hard cost — awarded-contract benchmarks (tiers A/A+) arrive with award ingestion and will recalibrate these numbers where declarations run low.
