AA Data · Parcel entitlement for Canada
We encode each city’s zoning by-law and run it on every parcel. Each lot becomes a record: homes allowed, the building that fits, the clause behind each figure and the rental market around it, by API or bulk file.

Entitlement drives land value, the loan a site can carry and the homes a city can count toward its target. Today it is read from by-law PDFs, one site at a time.
Lenders and insurers
$4–12K
and about three weeks for a consultant zoning report on one site
A construction loan waits on that report before it can be priced. One API call returns the same entitlement, with the clauses, in seconds, and a batch call covers a whole loan book.

homes at 40 Livingstone St E: by-law maximum, then buildable
Highest and best use starts from what zoning permits. The record gives both figures, the building envelope behind them and the rents in the lot’s CMHC survey zone.
Municipalities
23,000
homes Ontario asks Barrie to build by 2031; 1,459 counted in 2024 against 1,917
Targets are counted in homes. The city sees what its by-law allows on every lot, and what a draft or an amendment would change, before it reaches council.
The rules change. The data follows.
Ontario’s Planning Act s.35.1 now permits up to three units on a residential lot whatever the by-law says, and cities amend their by-laws through the year. A city re-runs in about a minute when a rule changes, and every snapshot is kept, so an answer can be replayed as of the day a loan was written.
What we have
Each layer keeps its source, licence and date. A field goes into delivered data only when its publisher’s terms allow commercial use; the rest is withheld and named in the record.
Zone standards, special provisions and the provincial rules that override them, each tied to its clause and page.
Every lot in 6 Ontario cities
Frontage measured at the required front yard, depth and area, from each city’s parcel fabric.

Products
The API and bulk files carry the record; the Government desk adds what a draft by-law would change; a site report prints one parcel. A city we encode for one buyer is ready for the others.
Parcel entitlement by API or bulk file, for underwriting and collateral review.
A capacity desk for staff: every lot in the city, what the by-law allows on it, and what a draft would change.
One parcel's record as a PDF: a free quick read on any address, or a feasibility study drawn to scale.

Why it is different
Zoning portals show what a lot is zoned. Permit feeds show what was filed. Neither says what the zone allows on that lot, and a consultant answers one site at a time.
| Consultant report | City zoning portal | Permit and application feeds | AssetAvenue | |
|---|---|---|---|---|
| Homes a lot allows | Per site, by hand | Zone name only | Not offered | Every lot, computed |
| Clause behind each figure | In the report text | Link to the by-law | Not offered | On every figure |
| A draft by-law tested on every lot | Not offered | Not offered | Not offered | Yes |
| Covers the whole city | One site at a time | Yes | Yes | Yes |
| Time to an answer | About three weeks | Minutes, then read the by-law | Not offered | Seconds |
| Cost per site | $4,000–12,000 | Free | Subscription | Per lot or annual licence |
Coverage
Cities are added by the size of their construction lending and the licence on their data. Only sources whose terms allow commercial use go into delivered data.
