Toronto early feasibility is a ladder, not a product: free desktop screens to $2,490 studies, $5,000+ engineering, and a $3,000 City check
Asked:
“How do Toronto builders, architects, and small developers currently perform early-stage feasibility checks, and what do they pay for them?”
As of 9 October 2026, 40 priced offerings from 23 independent hosts — City of Toronto pages, local architects, planners, design-build firms and software tools — map a staged, hybrid workflow. 24 of the 40 are free, mostly lead-generation screens from design-build firms; paid, more independent work runs from a $300 consult to $31,500+ pre-application engagements. All prices in Canadian dollars unless noted.
The feasibility ladder: what each rung costs and what uncertainty it retires
Free builder screens cover zoning, lot limits, unit mix, rough budgets and even rents — but they are sales-funnel estimates, not independent opinions or zoning certificates. metrohomesdesignbuild.ca
The cheapest documented, coordinated study is a $1,089 pre-design report; a full multiplex study covering up to 10 units starts at $2,490 + HST and is delivered in days. baukultur.ca · tesa.ca
City validation is cheap relative to the risk it retires: a 2026 Zoning Applicable Law Certificate benchmark of $214.79, and a $3,000 PAC deposit per application type that is credited against the application fee if filed. renovationrm.ca · toronto.ca
The $14,000–$31,500+ figure for a full planner-led pre-application engagement is single-sourced from one software vendor's page and should be read as a high-end benchmark, not a market average. prebuildiq.ca
Minimum viable stack, by who you are
Homeowner testing a fourplex or garden suite
Free desktop screen (City maps + a tool like Metrohomes or Plexora) to rule the lot in or out
One independent check: $300–600 architect consult, or the $399 written garden-suite report
If building: ZALC-style City zoning review (~$215) before committing to drawings
Cash outlay before design: roughly $500–800
Architect testing massing
Desktop zoning and overlay pull: by-law 569-2013, lot fabric, heritage/ravine/tree layers — free
Quick envelope and yield sketch in-house; a $1,089 pre-design study format is the benchmark deliverable
City ZALC review (~$215) to document as-of-right compliance for the client
Cash outlay: roughly $215 plus your own hours
Small developer considering acquisition
Free desktop screen plus a pro-forma pass with sensitivities (free tools exist; software from $199/mo)
Coordinated study from $2,490 + HST, or planning due diligence $1,500–5,000 if severance/ZBA risk
Engineering feasibility $5,000–10,000 if servicing or technical risk; PAC ($3,000 deposit) before filing
Cash outlay before firm offer: roughly $4,000–15,000

Method: 40 priced feasibility offerings extracted 2026-10-09, one row per offering, across 23 independent hosts (City of Toronto, local architects, planners, design-build firms, software tools); no single URL backs more than half the rows. Prices are as published, CAD unless flagged; duplicates of one provider's similar offers are collapsed in the ladder and shown in full in the table; 2022 City fee rows are kept for context only, superseded by the 2026 $214.79 ZALC benchmark and $3,000 PAC deposit. The $14,000–$31,500+ pre-application figure is single-sourced. Scope text trimmed for space.
