Cost Range Snapshot
GTA core and secondary Ontario PSF bands, with hard cost, soft cost, and HST exposure separated where useful.
A library of building-type-specific cost guides anchored in Q4 2025 benchmark data. Each guide explains the math behind a Class D estimate: PSF range, regional development charge variation, regulatory triggers, and the line items that move the budget materially.
Use these guides before, during, or after running the calculator.
Run the Class D Calculator Read the MethodologyEach guide covers one project type from the calculator's cost model and helps owners understand what belongs in an early feasibility budget.
GTA core and secondary Ontario PSF bands, with hard cost, soft cost, and HST exposure separated where useful.
Major scope items that move the budget, including envelope, structure, MEP, fit-out, equipment, schedule, and site constraints.
Planning notes for Toronto, Mississauga, Brampton, Halton, and secondary Ontario markets where development charges and labour conditions vary.
These pages match the strongest commercial search demand and the most useful calculator pathways for Ontario owners.
Distribution centres, tilt-up shells, cold dock formats, site servicing, and Reg. 851 trigger overlap.
Open guideMOH redevelopment, OBC Part 3, healthcare complexity, PHSR exposure, FF&E, and commissioning allowances.

Wave 1 starts with the five guides above. The next batch can expand into heavy manufacturing, food processing, clinics, schools, recreation, hotel, dealership, and self-storage cost pages.
Separate articles can explain development charges, permit fees, construction management fees, design fees, and Class D contingency reserves.
Those pages should come after the five priority building-type guides, because they support the calculator but are less important than the main commercial project searches.
Some cost drivers need a qualified engineering review before the budget can be treated as reliable: structural changes, MEP tie-ins, PHSR triggers, OBC Part 3 requirements, equipment installations, refrigeration systems, or sealed documentation for permits. ProWise Engineering is an important consultant resource when the estimate depends on those technical assumptions.
Connect with ProWise EngineeringIf you are still testing feasibility, start with the Class D calculator. If the project has drawings, documents, or a target site, request a detailed estimate review.
