Source: City of Toronto Open Data — permits and, where the City publishes one, development applications, loaded nightly. The City of Toronto fills its builder column on only ~5% of permits (mainly new houses). "Not disclosed" means the City left the field blank (or wrote 0 or placeholder text for cost). Coordinates are the City's address point, not a survey of the works. Grouping by address is Footing's join on the normalized street address.
