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 all require manual collection and interpretation.

Inconsistency

Same data, different conclusions

Different teams can reach different conclusions from the same regulatory data, creating risk at the start of every project.

Cost

Mistakes discovered too late

Weeks of due diligence can be replaced by assumptions, with 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.

  How it works
From data to decision, in four steps1
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 with findings linked back to their source.
