Why this exists

Understanding a site shouldn't take days or even hours

Most of the time, the information you need already exists. It is spread across planning portals, by‑law documents, policy layers, and mapping tools that weren’t designed to talk to each other.

  • What is this site’s potential?
  • What is the context of this property?
  • What policies apply to this site?
  • What risks are hidden in the data?
  • How do overlapping regulations interact?
Ratio.City brings all of this into one place, structured, mapped, and ready to use.
Fragmentation
Data lives across dozens of sources
PDFs, municipal portals, disconnected GIS systems, and internal files all require manual collection and interpretation.
Inconsistency
Same data, different conclusions
Different teams reach different conclusions from the same regulatory data, creating risk at the start of every project.
Cost
Mistakes discovered too late
Weeks of diligence can be replaced by assumptions, with critical constraints discovered only after capital is committed.
Outdated information
The rules change
By‑laws and policies evolve, and it’s not always clear which version of the rules you’re working with.

Who we help

Built for all professionals shaping Canadian cities

Different roles face different challenges. Find out how Ratio.City fits into your workflow.

De-risk every site decision before you commit capital

Most site evaluations begin with more questions than answers. The constraints that matter most are often the hardest to find.

  • Unclear zoning interpretations that slow decisions
  • Due diligence cycles that take weeks and cost more than they should
  • Hidden constraints discovered only after capital is committed

Validate what’s possible before you invest. Not after.

How it works

From data to decision, in four steps

Step 01
Find a site
Search by address or filter by zone, lot size, and location to find the property you need.
Step 02
Build your picture
Overlay zoning, policies, infrastructure, heritage, and environmental information in one view.
Step 03
Analyze potential
Understand what is permitted, what the development potential is, and how constraints interact.
Step 04
Share insights
Generate reports and align your team around findings linked back to their source.
No setup required. See results immediately.
The platform

A complete platform for site understanding

Locate

Understand constraints
Surface policies, heritage overlays, environmental risks, and regulatory interactions in one unified view.
Model
Test scenarios in 3D
Visualize what’s possible on a site directly within its regulatory limits, without switching tools.
Collaborate
Align your team
Work from a shared environment with the same data, the same context, and fewer conflicting conclusions.
Report
Export clear insights
Generate defensible reports with source attribution for every data point, built for confident decisions.

Data integrity

Built on real data. No assumptions.

All data is sourced, structured, traceable, and audited on a regular cadence.

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 on the Ratio.City platform is reviewed and linked to its source, whether municipal, provincial, federal, or partner.
