Geographic Township Improved

Coordinate system: 4269 - "NAD83"


This data set is a polygon coverage that can be used to identify the location of townships in the province of Ontario. A township is a fundamental land subdivision in the original survey fabric of the province as completed by the Crown. A polygon feature that identifies a surveyed area that may or may not comprise of lots and concessions.

The spatial accuracy for some of the township fabric from the NRVIS and the LIO warehouse was improved through the Ontario Parcel, Township Realignment and Township Improvement projects. Improvements to the fabric may include:

  • road allowance widths
  • spatial changes to better represent where the township boundaries are located
  • more consistent concession names
  • Materials used to improve the location of township lines may include:

  • Township Improvement plots
  • survey information (i.e. retracements)
  • original township plans
  • surveys notes, etc.
  • NRVIS physical features such as fencelines, and water bodies
  • GPS Ontario Road Network geometry
  • Other township improvement materials were also used to improve the lot fabric in some townships. Please note: not all townships have been improved.
