Toronto parcel picker + zoning
Click any lot on the satellite map. SiteYield pulls the parcel geometry, zoning code, exception schedules, MTSA / PMTSA proximity, heritage adjacency, and transit distance. Multi-parcel assembly merge.
Click a parcel to generate zoning-backed massing, a live pro forma, comparable approvals, and a decision-ready feasibility report — without rebuilding the same model from scratch.
Built for Toronto developers, architects, planners, and infill investors.
Parcel to pro forma in three moves.
Press Generate Optimal Massing and SiteYield reads your lot polygon, your zoning code, every applicable Toronto Tall Building Design Guideline, and the 362 most recent comparable approvals within 1 km — then returns a high-IRR option, benchmarked against recent approved precedent within 1 km to support a defensible planning case.
Everything else on this page — the custom geometry editor, the conservative, balanced, and aggressive approval paths, the live pro forma, the shadow study, the 40-page report — exists to refine what this button gives you. Most users stop after one click.
A real Toronto sample project, end to end — the same artifacts you generate for your own site.
58-storey mixed-use highrise — 691 units + 13,000 sf retail on a 12,938 sf downtown lot.
Read section →230 Adelaide St West — 12,938 sf in St. Lawrence, steps from St. Andrew subway.
Read section →CRE x48 site-specific exception — FSI 49×, well above the 2–3× CRE baseline.
Read section →58-storey tower on a 6-storey podium, 634,105 sf GFA — three massing options.
Read section →Sources & uses, 10-year DCF, sensitivity and Monte Carlo — fully editable.
Read section →Benchmarked to nearby ZBLAs reaching 40–60× FSI on downtown transit sites.
Read section →Entitlement, market and construction risks rated by severity, with by-law citations.
Read section →Formalize a ZBLA, confirm S37, commit affordable units, refine setbacks in SPA.
Read section →If you're checking whether a garden suite fits in your own backyard, you want SiteYield Home — same engine, homeowner-friendly UI, free.
Go to SiteYield Home →Site intelligence, massing, underwriting, and the deliverables a lender or partner actually reads — grouped by the order you use them. No juggling Excel, Mapbox, AutoCAD, and a planner’s email chain.
Click any lot on the satellite map. SiteYield pulls the parcel geometry, zoning code, exception schedules, MTSA / PMTSA proximity, heritage adjacency, and transit distance. Multi-parcel assembly merge.
Live capacity checks against City of Toronto and Ontario Energy Board open data — water, sanitary, stormwater, and electrical headroom at your address. Surfaces constraints before you commit.
300+ active applications within 1 km from Toronto’s open data — storeys, FSI, status, and decision dates. Sourced precedent for your rezoning narrative.
Trace any building footprint — L, U, chamfered, notched. Snaps to lot edges within 3 m. Drag any vertex to reshape.
Stack a wide podium and a stepped-back tower with per-edge step-back control to meet Toronto’s tower setback and separation requirements.
Curtain wall, brick podium, balcony stacks, mullion grid, rooftop amenity and green roof, mechanical penthouse — all parameter-driven.
Animate sun position by date and time, with equinox / solstice presets, cast onto neighbouring buildings and heritage districts to check Tall Building Guideline shadow windows.
Hard cost, soft cost, DC / CBC, parkland, financing, and sales velocity in one model. Move an assumption and every downstream number recalculates instantly.
Full 10-year DCF, tornado-chart sensitivity, and a Monte Carlo risk distribution — so you see the range of outcomes, not a single point estimate.
Per-unit pricing built from a base rate × floor, exposure, view, and corner premiums — closer to how units actually sell than a flat $/sq ft.
Reads your massing and estimates the likely approvals path — OPA / ZBA / SPA / Minor Variance — with Planning Act citations and comparable precedent. An estimate to plan around, not a legal opinion.
Bound feasibility report (Executive Summary → Recommendations), PowerPoint for IC memos, and CSV for the analysts.
Shareable view-only links plus .obj / .mtl 3D export into SketchUp, Revit, or Rhino — so your architect, planner, and lender start from your model.
Every figure traces back to a named source or a setting you control — nothing is a black box.
Pre-development is the ugliest part of building. The math is opaque, the data is fragmented, the tools are 1990s. Every developer's "feasibility model" is a personal Excel sheet built over a decade — undocumented, unsharable, untrustable.
SiteYield.ai exists because someone had to write the calculator that actually makes sense. One that respects the rigor of how developers, planners, and lenders really think — and one that produces output you'd actually send to your IC.
We're focused on Toronto first because Toronto is where we know the by-law. Vancouver, Ottawa, and the GTA are next. Every city we add deepens the same engine: real zoning data, real comparables, real construction economics.
Same engine, homeowner-friendly. Draw your lot and SiteYield Home checks setbacks, footprint, and how big a suite you can build — then hands you a feasibility PDF with a cost band and permit timeline. Free for Toronto homeowners.

As accurate as the assumptions you give it. Costs draw on the Altus 2026 Canadian Cost Guide, development charges on the current City of Toronto schedule (with Bill 23 rental treatment), and financing on current rates — all of which you can override. It runs full DCF, sensitivity, and Monte Carlo so you see a range of outcomes, not a single number. Treat it as a fast, defensible screening model, not a final appraisal.
Parcel geometry and zoning from the City of Toronto, By-law 569-2013 and its exception schedules, planning overlays, nearby development applications from Toronto’s open data, and the Tall Building Design Guidelines. Cost and financing benchmarks come from published industry sources. Every input is shown with its source.
Yes — every cost, rent, sale price, financing term, and timeline assumption is editable. The defaults are a starting point; the model is yours to tune to your deal.
No. It compresses the weeks between “I found a site” and “I know whether to pursue it.” Your architect still designs the building, your planner still runs the approvals, and your lawyer still gives the legal opinion. SiteYield gets you to a defensible go / no-go before you spend on consultants.
Toronto today — that’s where the by-law data is modelled in depth. The GTA, Ottawa, and Vancouver are on the roadmap. The engine is jurisdiction-agnostic; per-city by-law data is what takes time. Tell us where you build and we’ll add you to the list.
Your projects stay in your browser by default. Server-side save for cross-device access is opt-in and encrypted. We don’t train models on your projects, and we don’t sell your data.
Yes — a 40-page bound PDF, PPTX for IC memos, CSV for analysts, and .obj / .mtl 3D export that opens in SketchUp, Revit, or Rhino, plus shareable view-only links.
That’s what it’s built for. The report is structured for IC and lender review — executive summary, pro forma, comparables, planning pathway, and a risk register — with every figure traceable to a source or an assumption you set. It supports the decision; it doesn’t replace formal appraisal or legal due diligence.
