Teranet's Province of Ontario Land Registry Information System (POLARIS) property boundaries data


These datasets were provided to the Geospatial Centre by Teranet in 2005, 2006, 2007, 2008, 2009, 2010, 2012, 2014, 2016, 2018, 2023. Ownership parcels are based on title records from the Ministry of Government Services, reflecting the ownership boundaries of each property. 

The library has assessment parcels (not assessment values) which are based on records from Municipal Property Assessment Corporation (MPAC) and reflect assessment boundaries of each property. While these are typically one-to-one in urban areas, they are not always. An example could be a farmer who owns a single large parcel that is assessed for tax purposes as two properties – one at an agricultural rate and a second at a residential or industrial rate.

Please note that we do not have access to any property values, prices, sale history, etc.

In October 2007, the Regional Municipality of Waterloo provided to the Geospatial Centre a parcel-based file of coded land use information for the Region. This record has been joined to Teranet's ownership parcels for Waterloo in order to create a property parcel land use map of the Region of Waterloo. 

Region of Waterloo: land use 2020

This unique product was created by Geospatial Centre staff by combining: Southern Ontario Land Resource Information System (SOLRIS) 3.0 (2000 - 2015) with Teranet's Waterloo Assessment (2018).
