Address Prefill

Type the address. The form fills in.

Every listing starts with the same research: the board area and community, the school boards, the zoning, the roll number, the lot, the taxes. Listing Launchpad does that research the moment you type the address, fills what it finds into the listing and tells you where each value came from.

In short

Address prefill fills a new Ontario listing in two passes. A free lookup of public data comes back first: location, board area, school boards and, in about thirty municipalities, city open data such as zoning, lot, PIN and roll number, plus an estimated property tax. A web search then runs on the server and fills more. It only fills empty fields, and every value carries its source.

The public-record pass

As soon as you enter the address, Listing Launchpad locates the property and fills the postal code, the nearest cross street, which side of the street the house faces, directions and whether the area is urban or rural. It then places the property in your board's area tree, Region, Municipality and Community, for both the PropTx and Cornerstone trees, and names the school boards for the municipality. In Hamilton it fills the actual catchment schools as well.

In roughly thirty Ontario municipalities, including Toronto, Ottawa, Hamilton, Mississauga, Brampton, the York Region towns, Burlington, Oakville, Durham, Niagara, Barrie, Kitchener-Waterloo, Guelph, Kingston and London, it reads the city's own open data. Depending on the city, that can be zoning, garbage day, municipal water and sewer, lot area and shape, PIN, roll number, legal description, storeys, a pool and the year built.

Where an assessed value is found, it estimates the property tax from the municipality's current residential rate, and labels the figure as an estimate.

A web search that cites its sources

The second pass is a web search that runs on the server, so you can close the tab and it still finishes and saves. It looks for the property's own records and past listings, and it never searches the things only you should decide, like price, deposit, HST, MLS number, showing terms or rental costs. For a condo, it only takes a figure from that exact unit's own record.

The AI Auto-fill panel lists the sources grouped by what each one contributed, and the ones it searched and took nothing from. Each filled field carries a mark that says where its value came from and that you have not reviewed it yet.

Your typing always wins

Prefill only ever fills empty fields. If you type into a field while the search is running, your value stays. Search again re-runs the web pass later, still filling blanks only. The web search costs 3 AI copy generations and is refunded when it finds nothing.

Frequently asked questions

Will prefill overwrite what I typed?

No. It only fills fields that are empty, and anything you type while it runs stays as you typed it.

Where did a value come from?

Click the mark at the end of the field, or open the sources list in the AI Auto-fill panel. Every filled field records its source.

Does it work outside Ontario?

Not today. Board areas, school boards and the municipal data sources are all Ontario.

Is the property tax figure exact?

No. It is an estimate from the assessed value and the municipality's published residential rate, and it is labelled as one. Some municipalities with area-based rates get no estimate.

Does it cost anything?

The public-data lookup is free. The web search uses 3 AI copy generations from your monthly allowance and is refunded if it finds nothing.
