Why this exists

Planning decisions are still unnecessarily difficult

Before any project moves forward, teams need to answer simple but critical questions.

Planning teams don’t lack data.
They lack a clear, unified way to interpret it.
  • What can actually be built here?
  • What policies apply to this site?
  • What risks are hidden in the data?
  • How do overlapping regulations interact?
Fragmentation
Data lives across dozens of sources
PDFs, municipal portals, disconnected GIS systems, and internal files — each requiring manual collection and interpretation.
Inconsistency
Same data, different conclusions
Different teams reach different conclusions from the same regulatory data, creating risk concentrated at the start of every project.
Cost
Mistakes discovered too late
Weeks of due diligence replaced by costly assumptions — and critical constraints discovered after capital has already been committed.
Ratio.City brings all of this into one place — structured, mapped, and ready to use.
Who we help

Built for every professional shaping Canadian cities

Different roles face different challenges. See how Ratio.City adapts to your workflow.

De-risk every site decision before you commit capital

You’re evaluating sites under uncertainty — unclear zoning interpretation, long due diligence cycles, and risk concentrated at the very start of your process.

  • Unclear zoning interpretation
  • Long, expensive due diligence cycles
  • Hidden constraints discovered too late
Instantly validate what’s possible before investing time and capital.

Navigate policy complexity with a single source of truth

You’re managing multiple overlapping policy layers, stakeholder expectations, and inconsistent data interpretations — simultaneously.

  • Multiple overlapping policy layers
  • Inconsistent data across departments
  • Stakeholder communication bottlenecks
Bring policy, zoning, and context into one shared view your entire team can trust.

Test scenarios within verified site constraints

You need fast iteration at the feasibility stage — before committing to a design direction. Real context, from day one.

  • Feasibility studies taking too long
  • Iterating without real site data
  • Discovering limits mid-design
Model ideas directly within verified real-world constraints from your first session.

Centralize planning data with access controls built in

You’re managing growing pressure to digitize, standardize, and share planning data — internally and with the public.

  • Siloed internal datasets
  • Public vs. internal access challenges
  • Pressure to accelerate review cycles
Digitize, centralize, and manage planning data securely — with role-based access controls.

How it works

From data to decision — in four steps

1
Find a site
Search by address or filter parcels using real zoning constraints, lot size, and proximity parameters.
2
Layer data
Overlay zoning, policies, infrastructure, heritage, and environmental constraints in a unified view.
3
Analyze potential
Understand what can be built, what risks exist, and how constraints interact — all backed by verified data.
4
Share insights
Generate reports and align your team — every finding linked back to its source.
The platform

A complete platform for site understanding

Locate
Find opportunities
Filter parcels using real-world constraints — zoning, density, lot size, proximity to infrastructure and transit.
Analyze
Understand constraints
Surface policies, heritage overlays, environmental risks, and regulatory interactions in a single view.
Model
Test scenarios in 3D
Generate massing envelopes and test design scenarios directly within verified site constraints.
Collaborate
Align your team
Work from a shared environment — same data, same context, and the same conclusions across disciplines.
Report
Export clear insights
Generate exportable reports with source attribution for every data point — built for defensible decisions.
Integrate
Bring your own data
Layer your internal datasets alongside verified public layers — with full access control.
Data integrity

Built on real data. Not assumptions.

Planning decisions cannot rely on approximations.

No black-box outputs. No AI-hallucinated policy. Just data you can verify, trace, and defend.

AI can summarize information. It cannot replace verified planning data.

Each layer is validated, structured, and linked to its primary source — whether municipal, provincial, federal, or partner.
