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. Whether you're evaluating a site, reviewing an application, or trying to understand what's permitted in your neighourhood, getting a clear answer takes far longer than it should.
- 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 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.
Outdated information
The rules change
By-laws and policies change and it is not always clear which version of the rules you are working with.
