Toronto feasibility, computed
Decision-grade screening in minutes, not a $10k two-week consult — click a parcel for zoning-backed massing, a live pro forma, and a lender-facing report.
Built for Toronto developers, architects, planners, and infill investors.
BUILT ON OFFICIAL, AUDITABLE DATA — City of Toronto Open Data · By-law 569-2013 · Altus 2026 costs · not black-box AI
Underwrites against live, official data — not black-box AI
Reports cite these sources for every key input — including live filings from Toronto's most active developers.
Scroll the workflow. Every step is auditable, every number sourced — and the whole run takes minutes, not weeks.
Search any Toronto address or click a lot on the satellite map. SiteYield pulls the cadastral geometry, zoning code, exception schedules, overlays, and nearby planning context in one click.
By-law 569-2013, Tall Building Guidelines, angular planes, MTSA context, and 300+ live comparable applications within 1 km — every constraint cited to its source, not a black box.
Press Generate for the highest-value compliant scheme, or design your own like a game: stamp, draw, drag edges, pull the roof, split a podium. Live zoning warnings keep every move honest.
Hard costs, DCs, financing, unit pricing, DCF, and Monte Carlo — recalculated live as the building changes shape. Move a wall, watch the IRR.
A comprehensive, source-cited feasibility package — executive summary, comparables, planning path, risk register — ready for your lender or IC the same afternoon.
From a tower-on-podium to a row of freehold multiplexes — watch the building rise, the density resolve, and the returns land. Illustrative figures from real Toronto site parameters.
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 comprehensive report — exists to refine what this button gives you. Most users stop after one click.
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.
The same sourced, auditable feasibility package — read four different ways. No more reconciling the broker’s teaser, the developer’s spreadsheet, and the planner’s memo.
Screen more sites, faster. Go from listing to a defensible go / no-go — massing, pro forma, approvals path — before you spend on consultants.
List the upside, not just the lot. Package a parcel with zoning-backed massing, FSI, and value support a sophisticated buyer can verify.
Arrive at pre-consultation with massing already tested against 569-2013, angular planes, and sourced precedent within 1 km.
Stress the sponsor’s numbers against sourced costs, live comparables, and a full sensitivity range — transparent assumptions, cited inputs.
Comparisons reflect typical Toronto consultant feasibility pricing and timelines — not measured customer stats. We’re early; we’ll publish real numbers when we’ve earned them.
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.
See it live first. Upgrade when the deal is worth it. Every paid plan unlocks both SiteYield and SiteYield Home — one account, two tools.

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 comprehensive 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 key inputs cited to a source or an assumption you set. It supports the decision; it doesn’t replace formal appraisal or legal due diligence.
See it live, no signup required — the demo runs massing, a pro forma, comparables, and a lender-facing report across all three asset classes.
