LIO Topographic Data Cache

Note: Geospatial Ontario will no longer be making updates to the LIO Topographic Cache. The final update to this service was completed in September 2025 and the service will be discontinued in 2028. For more up-to-date information use the Ontario Vector Topographic Data Cache.

The Land Information Ontario (LIO) Topographic Data Cache is a collection of topographic data built using a series of pre-drawn maps. The maps are compressed for fast, seamless display at predefined scales. The topographic data includes constructed and natural features that make up Ontario’s landscape. The cache provides limited data from areas outside Ontario’s boundaries, such as the United States and adjacent provinces and territories.

Technical information
  The LIO Topographic Cache will remain available for use until 2028. However, the underlying data will not reflect any future updates.
  Some cache layers have been processed in a way that makes it easier for them to be displayed in a mapping product.
  Other layers are unchanged from the authoritative data.
  The cartographic symbology used in the data cache is intentionally muted to allow users to showcase their data.
  The LIO Topographic Data Cache is created from many source datasets as described in the LIO Topographic Data Cache user guide. If you are interested in obtaining this authoritative data, you can download it from Geospatial Ontario.
  Contact Geospatial Ontario at [email protected] to get a copy of the cache for use in mapping applications.   Additional Documentation Status  The final update to this service was completed in September 2025.
