Standard Delivery Options
Option for Polygonised Parcel Data
Nonstandard Delivery Options


The Ontario Parcel product is a digital product comprising assessment parcel data, and either ownership parcel data or Crown parcel data and supporting data. Ownership parcel data consists of ownership boundaries and property identification numbers (PINs). Assessment parcel data consists of assessment boundaries and assessment roll numbers (ARNs). Crown parcel data consists of Crown parcel boundaries and identifiers.

Supporting data varies depending on the geographic location in question. In areas where POLARIS (Province of Ontario Land Registration Information System) standard ownership mapping exists, the supporting data includes the geographic township fabric, plan boundaries and text, road and railway names, major easements, major water bodies and First Nations boundaries. In areas where BIM (Basic Index Mapping) standard ownership mapping exists, the supporting data includes the geographic township fabric, plan text, road and railway names, major easements, major water bodies and First Nations boundaries. In areas that have no ownership mapping at the time the Ontario Parcel product was created, the available supporting data is limited to the geographic township fabric, road names and major water bodies.

The accuracy of the Ontario Parcel product is variable from location to location and depends on the source data available and the build procedure employed. In areas where POLARIS standards were used to assemble the ownership mapping and where good control and legal or cadastral surveys were available, the data has better accuracy than other types of Ontario Parcel mapping. In areas where the product is assembled upon 1:10,000 (or smaller) scale topographic mapping, and where control and surveys are not available, or not used, the data is much less accurate.

Standard Delivery Options

Teranet’s Standard Delivery
A standard delivery consists of a series of CAD (Computer Aided Drafting) files. A separate file is delivered for each “map block.” A “map block” is a predefined geographic area, identified by a five-digit block number, that contains an average of 300 to 500 parcels.

An initial delivery would include all map blocks in the contracted area. Subsequent updates would include only those map blocks that had been updated since the previous delivery.

Clients have a number of options to customize their delivery of the Ontario Parcel product.

Update Frequency

  • Once every three months; or

  • Once every six months; or

  • Once a year.

Data Content

  • Ownership parcel data plus supporting data; or

  • Assessment parcel data plus supporting data; or

  • Ownership parcel data plus assessment parcel data plus supporting data.

For each option, all available features within the selected data types will be provided. In areas where there is no ownership parcel data, only the second option is available.

Datum and Projection

  • NAD 83, 6 degree UTM; or

  • NAD 83, 3 degree MTM; or

  • NAD 27 (74 adjustment), 6 degree UTM; or

  • NAD 27 (74 adjustment), 3 degree MTM; or

  • NAD 83 unprojected latitude and longitude.

For all deliveries of NAD 27 data, the Canadian National Transformation Version 1.1 will be used.

File Format

  • Microstation 95 DGN files; or

  • AutoCad DXF v12 files; or

  • AutoCad DWG v12, v14 or v2000 files

Option for Polygonised Parcel Data

Parcel data is entered in the database as individual boundary lines, each with a text item for the associated PIN, ARN or Crown parcel identifier. In addition to these CAD files, a set of polygonised parcels is also available to municipalities as a standard option. These polygons are created using software to merge the individual boundaries into a single polygon and assign the polygon with the appropriate identifier. Use of this process may involve some generalization, such as the approximation of mathematical arcs through use of a series of line segments.

Clients can opt to receive either polygonised assessment parcels or polygonised ownership parcels. Assessment polygons are associated with the ARN identifier while ownership polygons would be associated with the PIN identifier.

This data is available in any one of three formats: ESRI Shape, Intergraph GeoMedia and MapInfo. To create these files, data from several map blocks are merged together, for example, into a single file for a municipality. Updates would consist of the complete redelivery of all parcel polygons in the contracted area.

MNR’s LIO Warehouse Standard Delivery
Data is available from the Land Information Ontario (LIO) Warehouse in the following formats:

  • SNIF Shape files (in a structure format) - The assessment, Crown and ownership parcel data are available in separate layers.  Within the SNIF package are ESRI shapefiles (.shp, .shx, and .dbf) for the graphic data and ASCII files for the attribute data. Through the Ontario Parcel agreement, the ownership data is currently only available through the LIO Warehouse to full Ministry of Natural Resources (MNR) List Users.  Municipalities wishing to access the ownership data must be licensed through Teranet.  Municipalities, however, can access assessment data through the LIO Warehouse.

  • SNIF AutoCAD DXF v12 files (unstructured format) - The CAD files are only available to full MNR List Users as a package product based on Land Registry Office boundaries.  MNR List Users are eligible to receive parcel data within their jurisdiction.  The updates are provided as a separate file on a block basis. Within the SNIF package are assessment, Crown and ownership data, as well as background information such as roads, hydrology and township fabric.

Update Frequency

Licensed clients will eventually be able to access updates from the LIO warehouse whenever they wish through their LIDS account.

Data Content
LIO Warehouse

When accessing the SNIF Shape files, the client will receive the parcel boundaries and identifiers.  Assessment parcels are areas defined by a boundary, an Assessment Roll Number (ARN) and now where available civic addressing for each parcel. The ownership parcels are areas defined by a boundary and a Property Identification Number (PIN). Currently, only the geometry is available for the Crown parcels.

When accessing the SNIF AutoCAD packaged product, MNR List Users will receive assessment, Crown and ownership data, as well as background information such as roads, hydrology and township fabric.

Datum and Projection
MNR’s LIO Warehouse:

  • NAD83 geographic latitude and longitude

File Format
MNR’s LIO Warehouse:

  • SNIF ESRI Shape files (structured data)

  • SNIF AutoCAD DXF v12 (unstructured data, packaged product)

Option for Polygonised Parcel Data

Available from the LIO Warehouse in SNIF ESRI Shape files.

Nonstandard Delivery Options

In addition to the standard delivery options described above, Teranet, MPAC or MNR may offer other options. These could include:

  • Crown parcel data;

  • Additional copies of a delivery;

  • More frequent deliveries;

  • Data in other GIS or CAD formats;

  • Additional sets of polygonised parcels;

  • Transactional updates for some features;

  • Teranet's GeoServer data delivery product;

  • Ontario Parcel data bundled with third-party data or products;
